Re: Tiles upgrade Path

[Ken McWilliams]

Tiles and sitemesh are for traditional (non - single page applications)
development. Tiles has performance advantages over sitemesh. I don't think
the OP should experience any blockers with respect to tiles migration and
will gain version 3 benefits as well.

Re: Architectural considerations

[Ken McWilliams]

Regarding being at the right place, no this is a Struts specific mailing
list. The concerns you bring up are beyond the scope of Struts2, at least
in general. If you needed specific integration help, as you've seen the
people here are quite friendly, do feel free to ask.

Consider a general Java mailing list, and if you provide detailed
requirements and demonstrate efforts at an actual solution then Stack
Overflow would be good (they aren't too friendly if those requirements are
not met. While that can be challenging, the reward is faster and higher
quality results) given the previous threads I strongly advise a general
Java mailing list since the nature of advice is more sound-boarding than
specifics.

Re: How to determine if a Windows server is running Apache Struts?

[Ken McWilliams]

Programs can also be "exploded" (not in any type of zip file) so be sure to
search all files in the normal filesystem as well. To test your script just
create a couple zip files with some nested folders where you have placed
some made up files either called "struts.xml" or "struts2-core-*.jar" to be
sure that your script is able to identify them. If they don't find those,
your script is unhappy!

Re: How to determine if a Windows server is running Apache Struts?

[Ken McWilliams]

Struts isn't a stand alone program but a framework, typically seen as
project dependency which supports web development on the JVM.

I don't know the answer to 1) [although I will at the end go though the
process I would attempt to find such programs].

2) No. Struts2 [which is different code base from struts v1, and does not
share the same issues] is a Java Web Framework, it will run on any JEE
compliant web server, and will run on embedded web servers such as Jetty.

3) No. And the program list will not determine if the program uses the
struts framework.

How I would attempt to determine the issue:

Most programs will not have been obfuscated (which may make determining
this much harder).
Java applications are typically packaged as JAR, WAR, or EAR. These are all
just zip files. I would automate the process to scan for all such files,
open them recursively travel their internal folder structure and search for
either struts.xml OR struts2-core-*.jar where "*" is a version number, and
accumulate all such files and or paths to these files into a plain text
document and then check them by hand [to determine the version of struts,
and determine if it has the security exploit and/or is exploitable (if it
is isn't accessible to the outside world generally it isn't a concern, of
course this depends company size and the nature of what is being secured)].
Some assumptions could be made about the internal project structure that
could save a great deal of time but because of build differences these
shortcuts (assuming what folder libraries are stored in) could cause you to
miss something so it is probably best to just search everything.

Re: struts2 +rest service problem

As mentioned in the other thread have you added the conventions plug-in?

The indicated error indicates a failure of Struts2 to be able to find what
it needs so your posted source should not be at issue.

Re: struts2 with rest service

[Ken McWilliams]

Have you also included the struts2-conventions-plugin?


org.apache.struts
struts2-convention-plugin
2.5.10.1


struts2-rest-plugin most definitely depends on struts2-conventions-plugin
but it isn't a declared dependency. I've thought that was strange for some
time. All the bean configurations such as struts.convention.action.suffix,
couldn't work otherwise.

Todd, thank you this was a huge help!

I've followed what you did and added it into a demo project that isn't much
more complicated than what you provided, just so I know how it all works.

One of the things I found the hard way is if you move to Shiro 1.4 (the
latest) it won't start...

I would like to turn your project into an struts2/shiro integration guide
(although the provided project is quite straight forward). I'm using JPA
services to get my user credentials so a bit of a guide there wouldn't
hurt, so next step is to figure out how to make that work with shiro.

Regards,
Ken

The above was just a quick hack for illustration. If struts could extend
it's configuration and xml to provide package level scope (struts packages)
and object for such purposes, and some functionality to provide
configuration lookup from the perspective of a particular package a less
hackish/reflective hoop-jumping could be done when reimplementing the
conventions plugin, as it stands it's probably possible using this
interceptor technique.

That would be awesome. From having looked around on the web there is very

Re: Limitations using Struts2-conventions-plugin (lack of multiple configuration roots)

[Ken McWilliams]

Sure, doing Struts2/Shiro integration at the moment. Will come back to
this, it was a rant from running into issues when setting up some personal
demo projects. The limitation from one static configuration to cover all
conventions (which really just lets you use one convention, at least well).
And issues in certain configuration being picked up from the xml, views and
annotations(class and package level). Namely when actions are created by
only creating views, I didn't think I couldn't apply package level
annotations and have them configure the actions unless a class is also
created.

So yes I'll come back to this in a bit.

Re: Limitations using Struts2-conventions-plugin (lack of multiple configuration roots)

[Ken McWilliams]

Sure, it would be most ideal if there could be variables scoped to struts
action packages, and accessible from only within that package.

Step 1 (Create beans and constants scoped to the package level):
Simply creating an interceptor to hold all the configuration that is
currently found in struts-plugin.xml would be a lazy start, interceptors
are instantiated once per package so they meet the scope requirement well.
Perhaps creating extending


Step 2: (Create configuration based on the per-instance package state.)
I'm not sure how that would work out... The actions convention wiring
configuration would be run, once for each package that has this magical
conventions-config-interceptor in its stack. Probably creating a new
conventions plugin as proof of concept. I tried creation a configuration
provider a while back and got slowed down to the point of giving up.

End Objective:
To encapsulate conventions such that multiple types of conventions could
operate simultaneously starting at different roots. As an example, the rest
plugin depends on the conventions plugin however it changes the global
configuration in such a way that normal conventions no longer work. In this
way contributors could develop conventions based code which would be
readily mergeable with anyone else's (plugins which use conventions but
have no side effects).

Limitations using Struts2-conventions-plugin (lack of multiple configuration roots)

[Ken McWilliams]

I like to use the conventions plugin but find myself fighting with it more
often than not.

I think conventions should establish a "convention". Now the plugin
certainly does this in the *singular* but say I want restful services
handled by conventions, and then I want perhaps a set of packages to
contain public documents, and another set of packages to require some form
of security but also follow some sort of conventions... well I find it
impossible to use the conventions plugin and need to resort to additional
configuration. Creating packages in struts.xml, or using XML to override
the conventions.

Do you think it would be reasonable to have the conventions plugin, create
a new configuration interceptor for which all the constants (package level
constants, as there is one interceptor instance per stack), and the rest of
the conventions configuration could be looked up from each of these
configurations?

So the conventions plugin would need to check each struts package to see if
extends conventions-default and if so, wire the actions at startup for each
in turn. If that is too limiting perhaps just make this one interceptor a
requirement for the scan.

Also under this scheme, it would be good to create an "include" for the
Java package scan rather than the "exclude" which is more suited to one
root.

I think this scheme would greatly reduce annotation usage as it would be
possible to stay entirely within established conventions, rendering
overrides unnecessary.

Re: Update request to web site regarding Log4j and "Getting Started" section

[Ken McWilliams]

Sorry...

The following "Getting started" page "How To Create A Struts 2 Web
Application:
http://struts.apache.org/getting-started/how-to-create-a-struts2-web-application.html

Tells you to add:


org.apache.logging.log4j
log4j-core
2.8.2


When it should be both log4j-core and log4j-api:



org.apache.logging.log4j
log4j-core
2.8.2


org.apache.logging.log4j
log4j-api
2.8.2


Because struts has a dependency to an earlier version of log4j... if both
are explicitly specified even with x.x.x versions, most users would use the
latest and keep them in sync. It isn't fun to experience _any_ errors when
doing a starting tutorial.

Re: convention plugin struts.xml interceptors

[Ken McWilliams]

Am I wrong in assuming that this new package is supposed to be the default?
If so it should extend conventions-default and there is some constant that
should be set such that conventions uses this package by default.

Also, perhaps of greater importance: If conventions was working before then
the results would by default be in /WEB-INF/content/ and does not  now ask struts
to search at the root? In which case it probably won't find the previously
established views?

For reference see: https://struts.apache.org/docs/convention-plugin.html
Search on that page for:
struts.convention.result.path and
struts.convention.default.parent.package

Re: Struts2 Rest Mapper Taking Over Non Rest Json Result

[Ken McWilliams]

To solve a similar issue I ended up creating my own ContentTypeHandler. As
you already have a result it should be pretty easy to wrap (at least I
found it so). The problem is that after doing so all JSON will be handled
by your new Content type...

While this link shows how to use Jackson, you can create your own
implementation and then apply your own configuration in the same way:

Re: [Question] [struts2-rest-plugin] How shall I handle GET request /orders/{id}/items?

[Ken McWilliams]

There isn't a recommended way to handle deeply set lists as per your
example... Or I missed it. I'm not a fan of that plugin.

It is really trivial to do this without any plugins:
https://struts.apache.org/docs/wildcard-mappings.html
Wildcards or using the named-pattern matcher (although in the linked
documentation the heading is "Parameters in namespaces").

It may be possible to use conventions, it might be nice to use annotations
to specify the root and the child actions in the same class for grouping:
http://stackoverflow.com/questions/6037820/is-it-possible-to-use-wildcard-method-invocation-in-struts2-with-conventions-plu

Since you may need to resolve the child entity before fetching the child,
it might be convenient to have them in the same class... save you from
chaining.

Create/Update/Delete using the struts2-rest-plugin are pretty straight
forward but at only one level of access.

Re: Struts2 documentation and Stack Overflow

[Ken McWilliams]

The Tao of SO is changing all the time, perceptions of what was or was not
acceptable years back have changed. Documentation being so new I think it's
hard to say exactly how it will establish its self.   SO has _a_lot_ of
struts 2 questions... 10,334 at this time. If they were all distinct that
would be staggering but a lot of questions are minute variations of
each-other, if even that. Documentation could be used to fully explain
those sets and variations, so we can reference that one source. I've
stopped answering questions largely because struts2 isn't that complicated
and if one looks for all normal use cases, they've been addressed...
probably in triplicate.

What I am getting at is not reinventing the wheel. "About Struts", "About
Tags", "About Interceptors" there are things that can be said but in the
main, if it was to be all done over by several different groups... they
would probably need to speak to the same things before going someplace new.
Without some duplication, everything would be links. Which in theory makes
sense, in practice would result in unreadable garbage that wouldn't likely
be expanded upon.

I don't think it's any reflection on poor documentation by developers. The
Struts 2 documentation is very good. Sometimes the user community will do
interesting integrations, it would be trivial to plug this into
documentation but harder to get into official struts2 documentation. Which
frankly should probably be concerned with core functionality, aside from
plugins which document common integrations such as Spring. There are some
confusing areas involving some plugins that could stand for some user
supplied documentation. I think people would be more inclined to contribute
with some framework in place.

Anther way to put it, while the developer mind set is to factor out
commonality, "boiler plate is bad" It's really hard to create documents
without boiler plate. Templates and skeletons are our friend. I don't want
to move the whole site, but there are stubs that are reasonably needed.
Sound bites that have been well thought out, and silly to do over. It's not
a duplication, it's a shove another ship off the shore.

Struts2 documentation and Stack Overflow

[Ken McWilliams]

StackOverflow is a pretty huge site and a lot of people seek out Struts2
Q there, it would be nice if the Struts 2 documentation was available via
the new StackOverflow documentation initiative.

I was tempted to simply copy good chunks of the existing documentation,
there is certainly room for improvement but starting from scratch is
certainly a daunting effort.

What is the view on copying data from struts.apache.org to SO? (I know
there will be others from SO who follow this list and would probably do
pretty reasonable and good things with a green light)

Anyone can write a blurb, and it's looking a bit barren over there right
now.

Re: struts2-rest-plugin issues getting non-restful urls to cooperate

[Ken McWilliams]

I have not forgotten about this but in setting up a project I like
everything to work well, the restful urls and non-restful urls are more
less happy. My issue was with POST and PUT requests. The Action uses
model-driven, and with POST which calls create() all is well, while PUT
which calls update() and has almost identical code did not (there are a few
questions on StackOverflow with several different answers). The put method
also sets an id, and then decides to use model driven. I'm not sure what I
did wrong, anyways it somehow was solved out of frustration when I
re-implemented org.apache.struts2.rest.handler.ContentTypeHandler to use
FlexJson.

So a couple observations as a first time user of the struts2-rest-plugin:
- I like the Idea of this extension of conventions, adding constraints can
make you think along certain tried and true methods and make work faster.
- It would be nice if somehow this plugin directly required the conventions
plugin such that it also was able to incorporate the convention
annotations; that is, while these restful conventions are good being able
to override the result with a tiles result (and all the other conventions
overrides afforded with the well though out annotations provided by the
conventions plugin) would be particularly interesting.
- Since I couldn't get such annotations working I need non-restful urls to
render the views, which then call the service provided by the rest-plugin,
that really isn't a big deal.
- Back to results, the rest-plugin seems to favor ContentTypeHandlers...
which I was not familiar with until I ran into an issue where I didn't like
what it was producing. I found that I could recycle the code of my
FlexJsonResult type, if I used ActionContext to get the action (I forget
why right now, but there is a difference in method arguments) then I had
enough information to render what was needed.
- In using the rest-plugin for crud operations, I felt the need to create
interfaces so I would be forced/reminded of what needs to be implemented,
Struts2 has ActionSupport, it would be nice if similar interfaces already
existed for the rest-result type as there are a lot more methods which
typically need to be implemented.
- The documentation shows model driven, so I assume that is the suggested
method of use: I really don't like how the models type is required to be
Object because we are to support the index() method, which returns List
while the rest of the methods return T. So there are more often than not a
ternary operator in the getModel() method.

struts2-rest-plugin issues getting non-restful urls to cooperate

[Ken McWilliams]

I'm following these instructions to get restful and non-restful urls to
cooperate:

http://struts.apache.org/docs/rest-plugin.html#RESTPlugin-RESTandnon-RESTfulURL%27sTogetherConfiguration

Having followed the instructions on that page I've been able to set up a
project _only_ containing restful urls, but when I use the config which
supports both I get issues ( action not found).

A while back I used these instructions successfully but on an earlier
version of Struts. Can someone verify that these instructions work for
Struts 2.5?

I probably missed something really simple but a sanity test would be
greatly appreciated.

Re: Editing a JPA entity

[Ken McWilliams]

Just my two cents, you can avoid the lookup by using a JPQL UPDATE query.
If used to update a single record you avoid the lookup. If versioning is an
issue this may not be ideal (still you could manually set the version),
also if you expect to reuse objects you lose the ability to proxy, if those
are not issues... there is no reason not to do this.

Re: S2: How to tell if a response has been committed from an interceptor?

[Ken McWilliams]

Well you go down the chain create the result and then back up the chain.
So when going back up the response should already be committed.

see: https://struts.apache.org/docs/writing-interceptors.html

//modified code from above link to clarify
public String intercept(ActionInvocation invocation) throws Exception {
   //do stuff before response, going down the chain
   String result = invocation.invoke();
   //do stuff after response, going back up the chain, can't do what
you seem to be trying to do here...
   return result;
}

That aside, "Cannot create a session" isn't a good message because you
shouldn't be trying to create a session at all! It's part of the containers
responsibility to do that. You just ask for it. So the real cause of the
issue might be something else.

I think you should be able to add a more precise definition ahead of the

Re: struts2.5 - Action class is not called

[Ken McWilliams]

Well you are using wild cards in the action name. If you don't want to
switch between methods dynamically, that is you _always_ want to call
execute then you should remove the "*" from the name, remove the method
parameter, and then struts2 will assume execute should be called by
default.

Re: TokenInterceptor locking HTTP session for entire action invocation?

[Ken McWilliams]

Could a Striped lock not be used? If done, machinery would need to be
introduced which would quickly go beyond s2's prerogative. For instance an
interceptor could have this magic locking service injected and then say:
For User X, is token Y in use? Or for any user is token Y in use? But then
this brings up user management, which is outside of S2 and then security
quickly follows...

So keeping is simple, S2 offers a reasonable solution but I think you could
develop a more narrow locking scheme that locks on the value of the token
stored in a Striped lock:
http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/util/concurrent/Striped.html

Re: Struts 2 support of Java 8

[Ken McWilliams]

@Paweł, I must admit I had a similar problem, but it was not one with
struts2. When deploying with Glassfish you have to use the latest version
4.1 or lambda expressions in services will cause it to fail. Considering
the 4.1 was very recently released this was a big pain.

Re: Upgrading from Struts 2.0 to 2.3.16

[Ken McWilliams]

I'd be of the mind that during the upgrade that some how the resource:
'/mmr/jsp/templates/layout_
admin_window.jsp' and other folders were somehow moved and that
org.apache.tiles.
TilesException: ServletException including path is perfectly accurate.
Generally you don't want templates to be exposed and the include path
should start with /WEB-INF/...

If in doubt about dependencies follow one of the several struts2-tiles
integration threads using maven. I'm assuming you are not using maven. Then
copy the required dependencies into your project.

 Struts looks like it will be very useful to my web programming so
 I have ventured into the tutorials to
 start learning how to use it. I ran the first tutorial
 'basic_struts' successfully. Next, I am trying to
 run the 'Hello World' tutorial, but it is failing. I could use
 some suggestions on what may be wrong and
 some suggestions on debug methodology when using struts. Or at
 least pointers on where to looking
 for debugging techniques.  I am trying to do some reading to teach
 myself, but I'm floundering at this

 I'm running crunchbang Linux, using firefox 30.0, which is close
 to the latest edition. By the way, I'm
 aware of the firefox 'web console' but a beginner with that tool
 so I have not taken advantage of it so far.
 I'm running the tomcat6 server on my localhost.

 I have read the tutorial for 'Hello World' from:

 *
 *file:///usr/share/struts/struts-2.3.16.3/docs/hello-
 world-using-struts-2.html

 I have read each step in that tutorial and verified that the
 source code explained in the tutorial
 is in my sand box. I ran 'mvn clean project' and got a successful
 build. Then then copied the
 hello_world.war file to:

 * * /var/lib/tomcat6/webapps/hello_world

 *enter the URL:

 http://localhost:8080/hello_world/index.action

 in the address box on Firefox and got the following error from tomcat:

 My other webapps run ok out of /var/lib/tomcat6/webapps, so I at

 I thought about attaching the hello_world.war file, but because it
 is 4M-bytes, I decided not to. If someone would like
 to see it, I can provide it or a portion of it.

 I feel like there is an obvious error in my set up, but I cannot

  I have been using struts 2.1.8 for a while and last night noticed an

  For instance in the struts.xml file:

  - Within the package, I have an action mapping search
  - The webapp name is TestWeb.
 
  So to access this page, I can go to:
  http://localhost:8080/TestWeb/employee/search.action and this works.
  However, if anything is added to the URL after the namespace such as:
  http://localhost:8080/TestWeb/employee/someExtraText/search.action the

  Why does this happen?
 
 
  Reading the struts documentation
  (

OT: Architectural Semantics: Model View Presenter

[Ken McWilliams]

Marked as OT because this more of a conceptual issue and has to do with
talking to .NET developers regarding framework difference than with
framework use.

I'm trying to wrap my head around the Model View Pattern (MVP) pattern. My
issue is that I can't really differentiate it from what I do in Struts2.
But in no documentation is there any claim that Struts2 follows MVP. Also
it seems to be a term that only shows up mainly in Microsoft circles, is it
a sort of branding?

Given the Wikipedia article:
http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93presenter

There is a picture at the top of the wiki article that shows the following:


Model Business Objects = Presenter Contains the logic for application =
View UI Components Has no notion of the model.


This looks a lot like, the pattern most of us take for Struts2, where the
middle part, the presenter, is replaced by the Struts2 action.

The main difference is that this is less of an abstraction than found in
most JEE applications, as the chain is typically: Data tier objects =
service tier objects = struts2 action = view.

I'm supposing that this extra level, isn't required for the MVP pattern and
so omitted to focus on the pattern and not perhaps would be done in best
practice.

So is then is Struts2 following MVP (in most cases)? I've read that wiki
article twice and still don't see a difference. Any light on the matter
would be most welcome.

On the other hand if there isn't a difference, we should add Struts2 to the
list of MVP frameworks at the bottom!

Regards,
Ken

Re: Struts 2: Howto render output as HTML?

[Ken McWilliams]

If you want this behaviour for the whole application then set
struts.ui.theme to simple, inside struts.xml. Like so:

struts
   constant name=struts.ui.theme value=simple /
/struts

Since you mentioned a single page, you can do that too, you can even have a
single struts2 UI tag render under a different theme, these various options
are listed here:

Re: REST question

[Ken McWilliams]

Sounds like you have used the Open Session in View method... probably
provided by a custom interceptor, when adding the rest plugin you have
changed your action to the rest package and forgot to put your interceptor
back in place, so now you don't have a hibernate session and the view
generates this error.

 following exception:

 I know that's a Hibernate exception, but the jsp works fine without the
 REST Plugin.
 It's like the REST Plugin appends that extra s after the variable name in
 the .jsp or the value stack changes or something like that.

 The action is invoked without error in either case, and has into it's
 fields the required values.


 Does anyone has any pointer of what can be happening?

Re: S2 how to determine if a session exists from an Interceptor

[Ken McWilliams]

The OP has abstracted away most of the details, he is working with
MapString, Object! The session is not generally struts2s responsibility
it, generally it is maintained by the web container. Tomcat/Glassfish, etc.
And generally you would consider it in such an environment to always exist.
What kind of container are you deploying your application in? I recall
there being an interceptor that will attempt to create a session for light
weight containers, however if struts needs to create such a session object
it is doubtful that the container will be able to use it in a meaningful
way.

Could you please explain further what it is you are trying to do. Struts2
does things differently, if you are open to change there is probably a nice
way to resolve your issue. If we know a bit more... I'm certain we could
supply a much better answer than telling you to use the chain result

run (or possibly the short term) I have the feeling you're working towards
spaghetti actions.

Re: Tiles with Annotations

  convention-plugin has the advantage that it is not necessary to put an

Write an interceptor then apply it to the actions, assuming that the rules

Re: Struts Validation

[Ken McWilliams]

Have the action extend ActionSupport and have the class implement its own:
public validate(void).

Look at the code of ActionSupport (or JavaDoc) for how to set error
messages, if an error is set, after validate() executes, Struts2 will
assume an error has occurred and the action will return input.

This can be used in conjunction with the xml. Sometimes code just makes
more sense.

 executed as many times as there are objects the list ListEmployees.
 Now i have a Map of objects and i tried to write similar thing for it but

Re: Passing jsp tag attribute to Struts 2 tags

[Ken McWilliams]

Untested, and I didn't check the docs... but your expression in attribute
key of the following would require double evaluation. This is because an
attribute is a simple String or an OGNL expression. Your value in key
requires that concatenation occur after evaluation...

s:label key=form.label.%{name} cssClass=ym-required /

In stead an expression of the form: %{form.label. + name}, would be
better. Although there is still the issue of _name_ being in scope, maybe
you will need an  #attr. prefix...

Re: Re: Re: Url rewriting of .action to .jsp

[Ken McWilliams]

Sorry that was confusing. A new ModelDriven Interface would be better.

ModelFacing? from an Implementation perspective:
- push the Model object to the top of the stack such that members can be
set directly (same as model driven)
- register a pre-result listener, which will revert the action class to
being at the top of the stack.


ModelBacking?
- Leave the model as is
- Register a pre-result listener, which will push the object specified in
ModelBacking to the top of the value stack.

Since the later functionality is readily achieved using s:push there is
not much need for the second. But someone recently was talking about
managing legacy views
 and this sort of decoupling might have minor use in that case. It could
also have use with Struts results which expect a certain object, but then
using the appropriate interface directly on the action is more obvious.
Another possible use is for security. Certain results can serialize the
action, a decoupling here could be useful (on action uses the same class
for a JSP view, an XML producing result and a JSON producing result). In
this case having the opportunity to create an object against which the view
will only have access could make what people are supposed to have access to
clearer and allow the serializers to cleanly operate over the whole object
rather than having to use there APIs to prune parts of the tree.

Hope this is clearer. I don't know if it is just me. I like the idea of
ModelDriven but find that having the same model for the front and the back
too restrictive. After all the general flow in most actions is: Get data,
execute business logic, marshal data for view, possibly some processing of
view data...

How often do we want to send the same type of object back to the view we
just received?  Not that often.

Re: Inquiry

[Ken McWilliams]

It's a good idea to put your action classes into packages.

Not on the topic of the question exactly but the long inheritance chain on
your action is suspicious. Consider struts2 Interceptors and since you are
using Spring inject what you need where you need it.



 action name=GenericPresentationAction
 class=GenericPresentationAction method=listAll
 result name=list
 ${destination}
 /result
 /action


JL already asked where is destination defined? In the execute method of the
GenericPresentationAction class output to the console the value contained
in destination.

Does it contain what you expect? Also how is the value of destination
determined? Is it passed in from the client?




 action name=GenericPresentationAction_*
 class=GenericPresentationAction method={1}
 result name=input type=dispatcher
 param
 name=location/WEB-INF/jsp/setup/genericPresentationForm.jsp/param
 /result
 result name=success type=dispatcher
 param
 name=location/WEB-INF/jsp/setup/genericPresentationForm.jsp/param
 /result
 result name=list type=dispatcher
 param
 name=location/WEB-INF/jsp/setup/genericPresentationList.jsp/param
 /result
 /action



It would be helpful if we could see how tiles was tied into the above there
is no tile result type in clear use.
Also 'type=dispatcher' is the default, so long as you extended
struts-default.



 In tiles.xml:

 definition name=AdministratorBase
 template=/WEB-INF/jsp/setup/layout.jsp 
 put-attribute name=header value=/WEB-INF/jsp/setup/header.jsp
 /
 put-attribute name=menu value=/WEB-INF/jsp/setup/menu.jsp  /
 put-attribute name=footer
 value=/WEB-INF/jsp/setup/footer.jsp  /
 /definition
 definition name=GenericPresentationAction
 extends=AdministratorBase
 put-attribute name=title value=Presentación /
 put-attribute name=description value=Administrar Contenido /
 put-attribute name=content
 value=/WEB-INF/jsp/setup/genericPresentation.jsp /
 /definition


What version of tiles are you using?


 In spring-data.xml:

 bean id=genericHibernateDAO
 class=ro.dao.hibernate.GenericHibernateDAO abstract=true
 autowire=byName
 property name=sessionFactory ref=sessionFactory /
 /bean

 In spring-servlet.xml:

 bean id=genericPresentationDAO

 Hi you all developers! I'm currently developing a web application, I have

 first one extend action support. The web app uses tiles and when trying to
 find a Tile Definition to render ${destination} it can't find it. It says,
 cannot find ' ' definition. Other instance variables which are declared in
 the upper most class of the class hierarchy (I mean after action support)
 aren't able to be seen. I wonder what might be wrong since all other
 actions work properly. My CRUD system is based in the one that exists in
 struts2 in action book it is a version I improved. This action implements
 ModelDriven interface, whilst the majority doesn't. Thank you. I hope you

Understanding Struts2 Internals : Result Configuration

[Ken McWilliams]

The following is a direct copy of a question at SO which has been repeated
here for completeness but can be found here with nice syntax highlighting :
http://stackoverflow.com/questions/18650377/understanding-struts2-internals-result-configuration


In an effort to understand how struts2 loads its configuration I wanted to
display the path to the JSP which would be rendered. Given the following
very minimal struts.xml:

struts
constant name=struts.devMode value=true /
constant name=struts.ui.theme value=simple /

package name=base namespace=/
result-types
result-type name=dispatcher
class=org.apache.struts2.dispatcher.ServletDispatcherResult
default=true/
/result-types
action name=test class=com.kenmcwilliams.badwebapp.action.Test
result/WEB-INF/content/test.jsp/result
/action
/package
/struts

I want to be able to log /WEB-INF/content/test.jsp from within the
action. Given the following action:

package com.quaternion.badwebapp.action;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.interceptor.PreResultListener;
import java.util.logging.Level;
import java.util.logging.Logger;

public class Test extends ActionSupport {
//used for a sanity test on JSP
public String getMessage() {
return From test;
}

@Override
public String execute() throws Exception {

System.out.println(ActionContext.getContext().getActionInvocation().getResultCode():
 + ActionContext.getContext().getActionInvocation().getResultCode());
ActionInvocation ai = ActionContext.getContext().getActionInvocation();
ai.addPreResultListener(new PreResultListener() {
@Override
public void beforeResult(ActionInvocation invocation,
String resultCode) {
try {
System.out.println(PreResultListener resultCode:
 + resultCode);
System.out.println(PreResultListener result:  +
invocation.getResult());
} catch (Exception ex) {

Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex);
}
}
});
return SUCCESS;
}
}

There are three print statements which produce the following output on my
console:

INFO:   ActionContext.getContext().getActionInvocation().getResultCode(): null
INFO:   PreResultListener resultCode: success
INFO:   PreResultListener result: null

From testing both the result invocation.getResult() and the resultcode is
null *before* the PreResultListener is called but *within* the
PreResultListener the resultcode is set, yet the result still returns null!

From the JavaDoc of the getResult() method:

If the ActionInvocation has been executed before and the Result is an
instance of {@link ActionChainResult}, this method will walk down the chain
of ActionChainResult's until it finds a non-chain result, which will be
returned. *If the ActionInvocation's result has not been executed before,
the Result instance will be created and populated with the result params.*

Seems pretty clear that a result instance is *not* being created.

So how do I display /WEB-INF/content/test.jsp within this action? This is
not for typical struts2 use, I'm want to test a configuration provider for
which there is something wrong with the construction of the result for the
action, hopefully understanding why this isn't working will let me fix that
too.

Custom ConfigurationProvider is not able to find result

[Ken McWilliams]

Probably something silly but the following is just a rough effort at
proving to myself that I can add a new action though a configuration
provider...

It adds the package and action but there is something wrong with the
result. If the results name is set to error I get there is no mapping for
result success but when the name is set to success the message is then:
message *result 'null' not found


*
So it seems the result is mostly configured correctly...

import com.opensymphony.xwork2.ActionSupport;

Re: Interceptor in various struts.xml

[Ken McWilliams]

To be clear, the term submodule to me indicates some type of
encapsulation... you know that the includes only make one big XML file? If
this is a new project consider the struts2-conventions-plugin, if it is in
use I don't think your configuration should need to grow beyond more than
one xml file.

Re: AJAX Jsp tags

[Ken McWilliams]

I have some experience creating custom struts2 tags, but for ajax I do not
advise this route at all.  XML is not meant as a replacement for a
programming language, it is meant for configuration. It might seem
intuitive without further investigation that there are a limited number of
HTML UI elements and their functionality quite straight forward and so it
would seem reasonable that a configuration only route could work in the
general case. This is wrong as evidenced by all efforts to define dynamic
UI elements using XML.

Even JavaFX tried to use xml and that was abandoned, they had the benefit
of designing the entire environment from the ground up, which is hardly the
case here.

Not sure if you are familiar with the popular Question and Answer site
Stack Overflow, however a great many questions regarding the struts2 ajax
tags go unanswered. If people could find solutions for their configuration
issues I wouldn't be so open with my negative view of ajax tags. Since it
is most often new users of Struts2 that attempt to use these tags and to
what appears to be dismal results I can't help but think that these tags
may actually be of harm to the struts2 image.

I've only experimented with the jquery ajax tags breifly and experienced
frustration. Also before that experimented with the now deprecated dojo
tags. I had used the dojo tags within their prescribed limits but it is
much more enjoyable to have freedom. They were just too cumbersome. As soon
as you use JavaScript everything is far easier.

Try to use Unobtrusive JavaScript:
http://en.wikipedia.org/wiki/Unobtrusive_JavaScript

This will make your html tag like while allowing you to use the
JavaScript APIs as intended.

It is worth noting that the tag libraries can be used as templates. I bring
this up because one natural objection to not using a tag library would be a
loss in terms of this particular use. There are a number of other solutions
in this area one of them is Apache Tiles. JSPs, Freemarker, and Velocity
are all view technologies and while they have facilities for templates it
isn't their first concern. Apache tiles and Sitemesh both address the issue
of reducing boiler plate head on. Tiles does not try to do what the
aforementioned view technologies do, instead think of it as a way to factor
commonality out of any of those view technologies. As such both Apache
Tiles is a meta-view technology.

What I advise:

1) Avoid ajax tag libraries and write JavaScript by hand - even if you
don't know JS, you will be able to understand the documentation of the
popular JS UI elements and achieve the same level of functionality as
provided by the ajax tags even if all you do is cut and paste programming.
2) Follow the Unobtrusive JavaScript practice.
3) When writing JS do not hard code URLs use the struts2 URL tag (It will
pick up changes to the context root that way).
4) When asking for help with the client side, no one needs to know what
server side technology is used. The is greatly improve your chances for
positive feedback.
5) Use the Struts2-JSON plugin to produce data for your ajax consuming UI
elements and also as a means of accepting JSON data into actions.
6) When asking for server side support, try to insulate the audience from
your particular JS. (Determine that the correct data is being sent to the
server, if it not the issue is a client side, if the correct data is being
sent only provide that data [the query string or the JSON string]).
7) Use firebug plugin fore Firefox, it is a huge help.

8) Should you feel the need for a stronger templates solution consider
tiles (or sitemesh), this link points to it in a rather current use of it:
http://tech.finn.no/2012/07/25/the-ultimate-view-tiles-3/

Hope the reasoning is clear enough. I sincerely want to save you and anyone
else with similar concern some time and sanity.

Further the tag authors often lag behind the UI components that they wrap,
the documentation and features often fall behind too.

With even a trivial understanding of JS you should be able to produce the
same results as the Tags in the same time frame, as you gain experience
you'll quickly superseded the capabilities of any tag library.

Re: struts 2 ajax choice

[Ken McWilliams]

I don't suppose you would consider neither as a valid choice?

The short is the JS APIs are the intended intended to be used with JS not
XML. When you use these integrated tag libraries you end up with a brittle
solution. They can only factor in so much with XML. It makes about as much
sense as wrapping Java with XML tags.

So I'm certainly not saying don't use DOJO or jQuery I'm just skeptical of
the plugin benefits for either.

Re: struts 2 / sitemesh/ s: problem

[Ken McWilliams]

I know very little about sitemesh integration and am away from my
development machine but I think the integration guides mention you need to
use the StrutsPrepareFilter followed by the
SiteMeshFilter filter followed by the StrutsExecute filter.

Guessing but the SiteMeshFilter might be a custom one designed for struts2
integration (if there is a struts2-sitemesh-plugin) I'd verify if this is
the case.

Perfect.

As an asides: There not appear to be a unit test for
XmlConfigurationProvider, is it tested indirectly?

There was plans have Guice as a Struts2 Dependency? Is this still in

Re: Struts 1.1 and Tiles 2 compatability

[Ken McWilliams]

I don't know struts1 at all, but if you are afforded that ability to create
a custom result type then you should be able to manually invoke tiles (at
any version including version 3, which if you're going to put in the effort
should be your target). Here is how something similar was done with
Struts2, clearly not the same thing but the web.xml set up for tiles and
the dependencies for tiles would have the same starting point.

Re: Not setting instance member value in destination action using action chaining?

[Ken McWilliams]

This was already addressed on SO:

We explained that chain was a result and that the chaining interceptor did
not process additional parameters and so they would not be included, if you
want empMode to be true then have it as a property of the action and set
it's value to true before chaining and the comments also covered it is
generally best to avoid chain if possible.

What is unclear?

Re: struts2 and WebSphere dynacache

[Ken McWilliams]

Even then the solution is very limited. The OP probably wants to cache all
popular pages/reports, in many cases the same action will be responsible...
a singleton clearly can't address that.

It could be addressed with an object pool that was keyed to actions,
parameters and values and managed by an interceptor. I think it would be
tricky to implement, particularly the promotion of which resources to the
cache and which objects to dispose of.

Re: struts2 conventions plugin - how to override result type

[Ken McWilliams]

The right thing to do was override the ConventionsUnknownHandler like you
suggested. Right now the code is pretty ugly, I need to add unit tests to
my TilesUnknownHandler and then I wouldn't mind contributing it.

When the struts2-tiles-plugin is upgraded to account for tiles3 it would be
nice if it would check to see if the conventions plugin is in the class
path and then use then use the tiles result type by default (or if not by
default then as at least as an option).

Currently either the TilesUnknownHandler or the TilesResultType produces a
location of (namespace + # + file) and feeds that string as a tiles
definition:

definition name=REGEXP:(.*)#(.*)  extends=/test
put-attribute name=body value=/WEB-INF/content{1}/{2}/
/definition

The thing now is to define a convention for locating templates that makes
sense. Someway of dynamically generating tiles definitions from the content
under /WEB-INF.

Just a guess but I want conventions like configuration extended though to

  import org.apache.struts2.convention.annotation.Result;
 
  @Result(type=tiles)

  The tiles result checks the location parameter which if not specified in

  using tiles regexp convention can be carried on through tiles.
 
  My current issue is dropping the need for '
  @Result(type=tiles)' on every class. Any advice?

Re: Load Struts2 configuration from DB

If struts fails to find the action configuration it will try to use an

Re: [Struts2] SessionToken Interceptor used with json Result and Javascript Calls

On Wed, Nov 7, 2012 at 5:37 AM, Jan Fröhlich jan.froehl...@infomotion.dewrote:

 Hi...

 I try to secure one of my web applications with tokens.
 Everything works fine with basic jsp pages. But in one case, I call an
 action from javascript via jquery.ajax and return a json result.

 To do that, I added two properties to the json result object
 (documenTable) with token and tokenName and populate them in the action with
 documentTable.setTokenName(TokenHelper.getTokenName());
 documentTable.setToken(TokenHelper.getToken());

 The Javascript that gets the result object (data) looks like this:
 var submitData = {
 documentID : documentRow.documentID,
 showMessage : true
 };
 submitData[data.tokenName] = data.token;
 tdName.bind(click, function() {
 $.ajax({
 url : view,
 type: 'POST',
 data : submitData,
 success : function() {
 ...
 }
 });

 When the click event is fired, the parameters struts.token.name and
 struts.token are submitted with the request but the action returns
 invalid.token.

 Is that a way I can go? Is the TokenHelper the right thing to get a new
 valid token from?

 Any hints welcome!

Re: [Struts 2] How do I migrate an action with no result name to an annotation?

[Ken McWilliams]

Since you are using annotations I assume you are using the
struts2-conventions-plugin? If so, then the package structure after
struts2 or action is taken to be the namespace. If this is not the case
then you would need to override it.

I don't understand, your result always has a name. The default is success
and the type is by default dispatcher. So when you simply write
result/WEB-INF/jsp/myPage.
jsp/result those are implied.

  Hi:
 
  I'm trying to move all of my action configurations out of the
 struts.xml file into annotations. For the most part it's working fine. Yet,
 for my actions that have results with no 'name' parameter it doesn't work.
 For example, the following entry in my XML works perfectly.
 
 action name=start
   result/WEB-INF/jsp/register.jsp/result
  /action
 
  However, when move this entry to my action class it doesn't work. I get
 an No result defined for action...and result input error. What am I doing
 wrong? I feel like I'm missing some fundamental concept here. My SUCCESS
 and INPUT results work as expected.

Re: [Struts 2] How do I migrate an action with no result name to an annotation?

[Ken McWilliams]

Oh and please provide the full class name including package. You must have
your action in a package that _ends_ with action or struts2 (or struts
I think). Otherwise the package structure which follows that string will be
interpreted as part of the package structure.

Re: [Struts 2] How do I migrate an action with no result name to an annotation?

[Ken McWilliams]

Oh! With conventions you don't write any annotations! Simply create
/WEB-INF/content/my-action.jsp then the action my-action will be found.
You should stick to actions with hyphens as that is what conventions
expects.

You can't replace all of struts.xml with annotations. What Jeff proposes
would work but, annotations work on code... in this case it does not makes
sense to create code. So stick with the conventions, or use struts.xml.

 I infer from your comments that you are using a pass-through action to

 If that is true, this works for me just fine:

 @Action(value = start,
 results = @Result(location = /WEB-INF/testresult.jsp))
 public String dummy() {
 return SUCCESS;
 }

 A quote from the result-documentation[1]:

 * Likewise if the name attribute is not specified, the

RE: getText in error messages: resource bundle or bean value?

[Hoying, Ken]

I believe that your problem is that the field names are the same as your label 
names and with the validator both are in the stack. ${getText(user.password)} 
is first evaluating user.password and finding the field value 1234.  getText 
is then trying to locate an entry for 1234 and cannot find one so it is just 
return 1234.

It might work if you try ${getText('user.password')}.  Otherwise, you may need 
to rename it.

Subject: getText in error messages: resource bundle or bean value?

Hi,
I'm having a problem with getText().
I have the following xml validator:

field name=user.confirmPassword
field-validator type=requiredstring
message key=errors.required/
/field-validator
field-validator type=fieldexpression
param name=expression
(user.confirmPassword.equals(user.password))
/param
message key=errors.confirmPassSame/
/field-validator
/field

And the error message is defined in a bundle like this:
errors.confirmPassSame=The ${getText(user.confirmPassword)} field has to
have the same value as the ${getText(user.password)} field.
...
user.confirmPassword=Confirm Password
user.password=Password

I would expect a message like:
The Confirm Password field has to have the same value as the Password field.

However, when the error message is shown, instead of the text from the
resource bundle, what is shown are the actual values of the bean, like this:
The abcd field has to have the same value as the 1234 field.

Is this a bug in getText()?

Cheers,
J. Garcia

Re: how to write json/xml output using struts 2 and rest + convention plugin

[Ken McWilliams]

I'm not familiar with this application but simply look at the
documentation for the struts2-json-plugin, you can specify a json
result and you can specify include and exclude parameters (so you just
return the part(s) of your Action you want). In this way you could
define a new map, put a key of results with a value of New order
created successfully and return it quite easily. If the struts2
document is insufficient there are plenty of examples also on
StackOverflow, so take a look there too (Including many annotation
based examples).

Struts2 authentication, validation, and roles

[Ken McWilliams]

Asking for the consideration of a struts2 feature enhancement.

The roles interceptor depends on container based security, it is a bit
of a pain to set up and portability is complicated by needing to cover
more documentation steps (how to secure your application on Glassfish,
Weblogic, Tomcat...). This is container security and of course not
Struts2s issue but it would be nice it we could use the roles
interceptor by defining a
org.apache.struts2.interceptor.PrincipalProxy implementation and
specifying it with a struts2 constant:

constant name=struts.security.principalProxy
value=com.example.MyPrincipalProxyImpl/ //default would be
org.apache.struts2.servlet.interceptor.ServletPrincipalProxy

There is only a few place (that I know of) where the PrincipalProxy
interface aught to be used where currently the request is being used
(aught to be used if implementing this feature). That is in the
servletConfig interceptor when setting the PrincipalAware interface
of an action and in the roles interceptor.

It is not too much work to implement our own interceptors to
facilitate role based access but I think this would be helpful to many
and does not seem to require a radical change to S2 internals, so I
thought I would bring this up in the user forum to see what others
think.

Struts2 annotation with parameter when using json plugin

[Ken McWilliams]

Simply I want to evaluate a property of my action and use it's value
within an annotation. The following is exactly where I want to use it:

I want to define a excludeProperties parameter at run time.

Consider the following annotation which currently works on the action:
@Result(name = success, type = json, params = {root, model,
excludeProperties, myCollection})

There the actions model has a myCollection collection which I do not
want serialized.

However I would like to create an exclusion String (a string will do for now).

If I create a getter setter for exclusion, I would expect the
following annotation to work (which does not):

@Result(name = success, type = json, params = {root, model,
excludeProperties, ${exclusion}})

Any ideas?

I am using the named variable pattern matcher to extract values from
the namespace if that matters, I think it should just affect request
parameters.

I really want to dynamically set the exclude properties of the result.
I have not tried with XML yet, but shouldn't think it would be
different. Is is possible to directly create and set the methods of
the result type? Because that could be another option.

Re: Struts2-json-plugin serialization issue with a Hibernate backed JPA entity

[Ken McWilliams]

Solved! I've seen a number of posts relating to this issue but none with
solutions...

In searching for how $JAVASSIST_READ_WRITE_HANDLER came into existence
we find:
http://www.docjar.com/html/api/org/hibernate/tool/instrument/javassist/FieldTransformer.java.html


There we can see the getter for $JAVASSIST_READ_WRITE_HANDLER is
actually getFieldHandler so the exclude parameter becomes:

@Action(value = list-clients, results = {
@Result(type = json, params = {
excludeProperties,
^list\\[.*\\]\\.fieldHandler\\..*
})
})

And it all works... 

Just tested the shorter .*\\.fieldHandler\\..* and it works too, which
is much better because now there is one solution for all such
instrumented entities!

Re: Struts2-json-plugin serialization issue with a Hibernate backed JPA entity

[Ken McWilliams]

I need the root object to be list so this isn't going to help.

I'm pretty sure it is not trying to serialize the EJB service, the json
plugin will only try to serialize properties which have getters. 

According the debugger there seems to be a public property directly in
the entity called $JAVASSIST_READ_WRITE_HANDLER, I'm quite confident
that is in the attempt to serialize this object the issue occurs.

To be extra sure I set list as the root and the issue still occurs.

Struts2-json-plugin serialization issue with a Hibernate backed JPA entity

[Ken McWilliams]

I have a JPA entity, which hibernate is proxying.  

The following action works as it explicitly states the properties to
include, however what I would much rather do is use excludeProperties to
remove the problematic property. The problem property when serialized
causes a Positioned Update not supported exception.

The interesting thing is, all the properties on the entity class are
persisted correctly if explicitly included.

Looking in the  the debugger shows there is a property called
$JAVASSIST_READ_WRITE_HANDLER of type FieldInterceptorImpl which
Hibernate/JPA adds to the entity. I'm pretty sure this is what is
causing it to fail.


I've tried the following: 
@Action(value = list-clients, results = {
@Result(type = json, params = {
excludeProperties,
list\\[.*\\]\\.\\$JAVASSIST_READ_WRITE_HANDLER.*
})
})

but with no luck.  Following is my action and the entity class.

 

Here is my action (In a _working_ state):
/
@ParentPackage(json-default)
@Result(type = json)
public class ListTable extends ActionSupport {

@EJB
private ClientService clientService;
private List list;

@Action(value = list-clients, results = {
@Result(type = json, params = {
includeProperties,
list\\[.*\\]\\.name, list\\[.*\\]\\.id, list\\[.*\\]\
\.timelogCollection\\..* 
})
})
public String listClients() {
list = clientService.list();
return SUCCESS;
}

public List getList() {
return list;
}
}
/

Here is the entity:
/
@Entity
@Table(name = client)
@XmlRootElement
@NamedQueries({
@NamedQuery(name = Client.findAll, query = SELECT c FROM Client
c),
@NamedQuery(name = Client.findById, query = SELECT c FROM Client

public Client() {
}

public Client(Integer id) {
this.id = id;
}

}

this.id = id;
}

this.timelogCollection = timelogCollection;
}

@Override

return hash;
}

Re: sending the report directly to the printer

[Ken McWilliams]

This requirement would only make sense to me if this is in an intranet
where you have direct access to the printers. Then you could somehow get
your app to talk a print server.  It would be quite possible to make an
intelligent guess as to which printer in the company to send the
printout to based on the IP of the client.

struts2 property tag, how to dynamically set property name

[Ken McWilliams]

Hello I have a list of properties from a POJO as found using
introspection.

I want to iterate over a result set for each row, and iterate over a
list of property names for each cell in a table.

Something like:

s:iterator value = resultList
tr
s:iterator value=propertyNames //I want propertyNames to be
evaluated and the result used as the value for the iterator, not simply
interpreted as a normal list.
s:property/
/s:iterator
/tr
/s:iterator

If there is no way to do this then I'll create a BeanMap out of every
record in the result set (list of POJO's returned via JPA).

Re: struts2 property tag, how to dynamically set property name

It looks like I need to use a PropertyAccessor and
ognl.MapPropertyAccessor specifically.  Are there any demos in how to
use it, can one use it directly from the JSP?

Re: struts2 property tag, how to dynamically set property name

[Ken McWilliams]

Well I don't know if MapPropertyAccess would do what I want but found an
answer:

The following iterates over a list of POJO's and the properties are
determined for the particular POJO at run time and put in the
propertyValues list. The following is able to look up the property value
dynamically with OGNL. 

h1Print Table/h1
table border=1
s:iterator value=result var=record
tr
s:iterator value=propertyValues var=key
td
s:property value=%{#record[#key]} /
/td
/s:iterator
/tr
/s:iterator
/table

Re: struts2 property tag, how to dynamically set property name

[Ken McWilliams]

Thank you Dave, I just managed to resolve the issue in a slightly
earlier post.

Here is the action that backs the JSP. Now In my table I have a column
which prints out db.localhost.test.Groups[name=ADMIN] because the object
is db.localhost.test.Groups and it has a single property called name.
Another thing to fix.


package struts2.reflection;

import com.opensymphony.xwork2.ActionSupport;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Query;
import org.apache.commons.collections.BeanMap;

/**

 * @author ken
 */
public class GetPropertyNames extends ActionSupport {

List result = null;
BeanMap propertyValues = null;

private EntityManagerFactory entityManagerFactory;

public void setEntityManagerFactory(EntityManagerFactory
entityManagerFactory) {
this.entityManagerFactory = entityManagerFactory;
}

@Override
public String execute() {
EntityManager entityManager =
entityManagerFactory.createEntityManager();
Query namedQuery =
entityManager.createNamedQuery(Customers.findAll);
result = namedQuery.getResultList();
if (result != null  result.size()  0){
propertyValues = new BeanMap( result.get(1) );
//has unwanted property class but there is no valid remove
method that will not throw an exception, so will take care of this in
getter
}
return SUCCESS;
}

public List getResult(){
return result;
}

public List getPropertyValues(){
//can now remove unwanted property class
ArrayList arrayList = new ArrayList(propertyValues.keySet());
arrayList.remove(class);
return arrayList;
}
}

 Evaluated in what context? As a list of named properties on the item
 being iterated over? Are you implementing this in Java, or different
 JVM language?
 
 I thought I remembered foo[propName] just working, but I couldn't
 tell you what I was backing the view *or* model with, which could make
 a huge difference :/

RE: getRequestURL and action

[Ken McWilliams]

This question on Stack Overflow is very similar to your issue:
http://stackoverflow.com/questions/4773063/tiles2-struts-switch-locale

The parameter name for which the i18n interceptor determines the
language is configurable, I have not tried this but it may be possible
to specify a session_locale parameter for which it will determine the
correct language bundle. That is if you need the change to persist
across pages.  

Then you could configure an interceptor to capture any request_locale
parameters and setting session_locale to the same value.

As mentioned earlier in the thread the s2 a tag and s2 url tag have many

The following will work fine:

Don't bash HTML sometimes it is the far better path, although not in

 Maybe make the URL a variable and access it w/ JSP EL in the anchor tag?

Can Struts2 map params of the form a[]=2a[]=3a[]=4 to String[]

[Ken McWilliams]

Using jQuery, it is not a big deal to set $.ajaxSettings.traditional =
true;  such that jquery encodes in the form: a=2a=3a=4 but it is
enough of a nuisance for me to check if I can set something in
struts2.2.1 to avoid this.

Re: Dependancy Madness: Struts 2.2.1 spring 2.5 (preferably later ie: 3) and JPA2 backed with Hibernate

[Ken McWilliams]

I took your advice, there were to different versions of spring. Then did
the rest of the hacking needed to upgrade struts 2.0.6 with dojo to
2.2.1. 

Now on my list:
1) Change the demo to use jQuery + stuts2-json-plugin
2) Upgrade spring to 3+
3) Upgrade Hibernate and jpa to support JPA 2.
4) See if I can get the demo put back up on the struts wiki (saving
someone like me a lot of time!)

Again thank you so much!

  I'm experiencing issues upgrading the struts2-spring-2-jpa-ajax demo

  I've set up quite a few 2.2.1 projects I've just had a hard time

  has an updated version of this demo (Struts 2.2.1, jpa 2, spring

  With the above project I followed:
  http://struts.apache.org/2.2.1/docs/create-struts-2-web-application-using-maven-to-manage-artifacts-and-to-build-the-application.html
 
  So I removed struts2-core and struts2-spring-plugin and added back the
  2.2.1 version of the struts2-spring-plugin (because it adds back
  struts2-core) and added javasssist (although there is still an older
  version because of the hibernate dependency) added log4j dependency and
  xml file and switched to using the

  filter.
