Latest Opinions on Struts GWT, and Maven and GWT
Hello, Struts world... After a long time of not being able to follow the list very closely, i'm getting back up to speed building Struts 2 webapps, and i wanted to see what people thought about a couple of things we're investigating. First, we're having really great exploratory results with GWT, and are looking to integrate some UI widgets built with it into our webapp. I've looked at the GWT plugin, and I'm not immediately convinced to begin using it. We've already integrated Musachy's JSON Plugin, and it seems totally plausible to me to just use that from the GWT side. Does anyone have any direct experience that might persuade me differently? The other, bigger issue on my mind, is how to integrate GWT into a team development environment. I've found a couple of Maven/GWT plugins, but I have reservations about both of them (I'll have to review if anyone challenges me to say what those were!) So again, does anyone have direct experience using Maven and GWT, and if so, how are you going about it?

Re: [OT] How to handle non UTF characters in XML
See, the problem is that you're not handling the character encoding correctly in general. You should use String's getBytes method only when you know what you're doing, because the whole point of character encodings is that you can represent any given string with different sequences of bytes. I'd suggest doing more research on encoding in general: here's one popular piece, although not Javacentric: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)http://www.joelonsoftware.com/articles/Unicode.html From there, you may want to review the APIs for java.io.Reader and java.io.Writer, which are specifically designed to help smooth over the issues involved in serializing Java strings to bytes. This looks like it's going way too far off topic to be something that should be discussed much further on the Struts list.

I am extremely fond of using Spring to establish an application context (not to be confused with the webapp application context) and letting most of my code be blissfully ignorant of how things get set up. This page is the place to start on using the Spring plugin with Struts 2: http://struts.apache.org/2.x/docs/spring-plugin.html In short, Spring can instantiate any beans you want, either as singletons or as prototypes (that is, a new bean is instantiated each time it is called for from the Spring app context). In instantiating, it can also satisfy dependencies automagically. In the Struts2/Spring model, this is usually applied to action classes, which would be instantiated by Spring when requested by Struts. Spring would just give you an Action instance with a reference to your factory (although once you start digging in Spring, you might find that you can even hide the Factory and keep your Actions super simple and flexible.)

If you should instead use the Spring 2.xDTD (which you could, because Struts depends upon Spring 2), you must be aware that the default instantiation model for Spring 2 is singleton, not prototype, and that is at odds with the model behind WebWork, which assumes that each action is instantiated once per request. Thus, the example which is in the page referenced above: bean id=bar class=com.my.BarClass singleton=false/ would become bean id=bar class=com.my.BarClass scope=prototype/ Took me a little bit to realize that that was the source of a few quirks when I was first setting out with Struts2/Spring2. -- Joe Germuska [EMAIL PROTECTED] * http://blog.germuska.com The truth is that we learned from João forever to be out of tune. -- Caetano Veloso

I'm not suggesting that my way is the best way, but if you have a requirement to write unit tests for all of your code, then it's easier to stay away from the Servlet API. That is absolutely true. Then again, static initializer blocks can bring headaches of their own. I have never been very comfortable with them. I find that using Spring steers one to design code that is eminently unit testable, to the point where one need not use Spring in testing; one can simply satisfy a few simple dependencies as Spring would, and let the tests run. This is ultimately more a factor of designing for dependency injection than a characteristic of Spring itself, but I like Spring so... One of the great strengths of Struts 2 is that it does a much better job of hiding the Servlet API, making for components which are much more plausibly unit-testable.

Re: jsessionid appended to URL and page not found`
The solution Christopher and Dave discuss above can be handled with this in the Apache httpd.conf file: RewriteRule ^(.*);jsessionid=.*$ $1 This strips the session ID from anything that the HTTPD server is handling, although it should still get passed through the proxy. To be honest, our apps depend on cookies for other reasons so if URL rewrite sessions didn't work, we might never notice. The fact that your proxy config is not correctly brokering some URLs over to the servlet container would depend on how your proxy config is set up; I'm not very experienced in actally setting this up, but my diagnosis is correct, then the Struts mailing list is not the best place for the question anyway...

Re: Struts2, tiles2 and character encoding problem
OK, a few more notes: just to be clear, I have specified struts.i18n.encoding=UTF-8. This is not used to directly set the response character encoding. I use a CharacterEncodingFilter to set encoding to UTF-8. In my experience, a CharacterEncodingFilter is used to control the request content type, not the response content type. That's what the Spring class called CharacterEncodingFilter does. Assuming yours is the same, it won't come into play in debugging this problem. I specify meta http-equiv=content-type content=text/html; charset=UTF-8/ on the page. I am not sure whether browsers allow this to override an explicit content type set in the HTTP response, but in any case, it's more important that the HTTP response header be explicitly set. In a local test application I have, the servlet container is setting the header even when I don't explicitly set it. Using the latest code, I've tested going directly to a JSP (no struts), going to a default result (RequestDispatcher.forward) and going to a Tiles result. I get an explicit content type in all three cases, even though the JSP itself doesn't set the content type. I think there's something about that in the Servlet spec, that the container is required to set a content type, although that's at odds with what I experienced when I filed TILES-28 and with Elin's experience, so I'm not sure.

Re: jsessionid appended to URL and page not found`
What is handling the basic HTTP service for your application? If it is not a servlet container, but rather an HTTP server which proxies certain requests to a servlet container, then there is probably just a configuration problem. The scenario you describe is standard. A Servlet Container (or maybe it's the JSP engine) is supposed to encode the session ID in URLs unless it knows that the client accepts cookies, which it can only know if the client already presented a cookie with a session ID in it (as on reload or later clicks through the application.) If you don't have an HTTP proxy in the middle, then what servlet container are you using?

For everyone who is using Tiles 2, note that very soon now, the SNAPSHOT version of Tiles will be changing the URI for the TLD from http://struts.apache.org/tags-tiles to http://tiles.apache.org/tags-tiles so you will need to update the taglib declarations in your JSPs. (We use a JSP include directive like this %@ include file=/WEB-INF/tiles/_boilerplate.jsp % so that we only have to change it in one place. If you don't do something like that, then I hope you have a good global search/replace option... I will probably build a new Maven SNAPSHOT in the next few days unless another developer does it first. (Note that if you're using Tiles 2, you probably ought to monitor the [EMAIL PROTECTED] list in case no one mentions things like this to the Struts user list. In general, Apache projects expect discussion of pre-release software to occur on dev lists, not user lists.)

Re: [s2] getting servletContext in actions
Jeff: I think there are a lot of possible routes, but I'm not sure I understand your goal. Could you just have your service implement ResourceLoaderAware? If your Spring ApplicationContext is a WebApplicationContext (as it would be if set up by ContextLoaderListener), then the ResourceLoader would check the ServletContext for resources in addition to the class path, etc. If you don't want your service to implement a Spring interface, there are some Spring beans that help bridge the gap, briefly name-checked here http://www.interface21.com/news-home/2005/spring-1.1.4-released These mostly just let you apply ServletContext attributes to Spring beans in various ways without binding your code to the Servlet API. My hunch is trusting that the ResourceLoaderAware is the right solution, especially now that I realize that if you're passing in a ServletContextResource, then you've already accepted the Spring API into your service layer. Does that help? Joe On 1/31/07, Jeffrey Hau [EMAIL PROTECTED] wrote: Hi Joe, Thanks for the helpful information.

Re: newbie question...struts2, spring and jdbc
On 1/31/07, Cecilia Castillo [EMAIL PROTECTED] wrote: I am new to Struts, Struts2, and Spring. (And maybe know too much about jdbc.) I have written my application with Struts2 and am only using Spring to manage my database connections. I have defined my oracle database as a JNDI resource in my Tomcat server.xml file. I have defined a dataSource bean in my applicationContext.xml for my database JNDI resource. I have written some DAO classes which are spring beans defined in my applicationContext.xml. These all have a dataSource property pointing to my database. These DAO classes have methods which execute various db stored procedures or select statements. Now, I have some strut2 ActionSupport subclasses which do something like this in my execute() method ThingDao thingDao= (ThingDao )getBean(ThingDao); All is well, all is working. However, what I want to know is something about how Spring works. Does it manage these beans as singletons? In Spring 2, bean lifecycle is controlled by the scope attribute of the bean element. See http://www.springframework.org/docs/reference/beans.html#beans-factory-scopesfor more info. Also, the scope defaults to singleton, which is counter to the original model for Struts2 Actions, where each action is generally expected to be instantiated once per request. For your DAO bean, etc, of course you would choose for yourself whether to set to a singleton scope or a prototype scope. Or every time the execute() method is called, and I get my dao bean, does it instantiate a new instance of the dao bean object? Should I save this dao bean object in a private member of my ActionSupport class and reuse it everytime execute() is called? This suggests that your model is also counter to the Struts2 model. If you are writing Action classes with properties that are populated based on request parameters, you will be subject to concurrency problems (race conditions) if you have singleton actions. I'd recommend against it. Actions are supposed to be lightweight. At what point does Spring get a database connection...when the dao bean is instantiated, or when the dao bean executes() some jdbc call. (I assume this is when it makes a jdbc call, but I just want to confirm). This I can't answer directly, but remember that Spring is open source. You could check the code. If anyone can enlighten me or point me to some good documentation on this subject, I would appreciate it. Spring's own documentation (referenced above) is thorough and pretty clear. There are also a number of good Spring books. Hope this helps.

Perhaps that will help. I have to stress once again that Tiles 2 has not been released. If you are interested in using it, you have to be ready to get inside the code to understand how it works until more documentation is written (and to be ready to make changes to your code as changes get made to the framework, since there's no specific backwards compatibility baseline we have to guarantee for the first Tiles 2 release.)

Re: Struts 2 and tiles
The struts-tiles-plugin depends on the nightly snapshot of Tiles 2, which means that some things may get out of sync with the docs -- for instance, we've recently been working on clarifying the names of some of the JSP tags and I know for a fact some of the doc at tiles.apache.org is not in sync with the current snapshot. The example I gave is for using the TilesListener (ServletContextListener) instead of the servlet, as in item (2) of the Confluence Wiki page ( http://cwiki.apache.org/S2PLUGINS/tiles-plugin.html) In this case, the context-params are for the general Application Context and would probably go right above your filter element for the Struts 2 FilterDispatcher. I have only just recently reconnected with Tiles development, but I suspect that the TilesResult would work if you used the Servlet, but if you don't intend to allow direct links to tiles, then there's no reason to use the servlet; the Listener will take care of initializing the configurations, and that's all that the Struts2 Tiles Plugin needs. Note also that there are some differences in the DTD for Tiles2: more attempts to simplify and clarify compared to Tiles1. The new DTD is at http://struts.apache.org/dtds/tiles-config_2_0.dtd (although I guess we may want to move it to tiles.apache.org before officially releasing Tiles 2.) The main difference I can think of offhand is the XML attribute path in the definition element in Tiles 1 becomes template in Tiles 2.

I don't think so, although I'm just reading that ticket for the first time

In short, it looks like the DebuggingInterceptor always assumes that a
session exists, when in Bob's case, the session has not been created.
The easy work around would be to disable the debugging -- turn off devMode,
don't pass the debug param with a value of console, or define an
interceptor stack for your actions that doesn't use the
DebuggingInterceptor. I'm not sure that the Struts2/Webwork API provides a
clean conceptual way to know that it's not safe to write to the session, and
I'm not sure what the DebuggingInterceptor is trying to do in putting
something in the session. (It looks like that operation has moved to line
210 in SVN Head -- at least, there's only one call to SessionMap.put that I
can find.
(ll 208-211:
if (devMode consoleEnabled) {
final ActionContext ctx = ActionContext.getContext();
ctx.getSession().put(SESSION_KEY, ctx.get(
ActionContext.VALUE_STACK));
}
)
As you said, it will appear to work because this is happening probably after
everything else has already been invoked.
I haven't spent much time with the debug facilities, so I can't offer much
more of a suggestion as to how this should be fixed, but it probably
deserves to be filed as a bug.

http://svn.apache.org/viewvc/tiles/trunk/tiles-core/src/main/java/org/apache/tiles/taglib/PutListTag.java?view=log
)
I didn't build a new snapshot, because these changes also involved changing
the names of some of the tags and committers were not 100% united that the
changes were correct.
(see
http://www.nabble.com/-Tiles2--JSTL-functions-for-Tiles-taglib--t2961079.html
)
If you build from SVN and change some JSP tag names, you will probably be
ok, although I am not a regular user of the PutList tag; I just found these
issues while working on the rename and testing the changes.
Questions about unreleased code like Tiles2 are generally better aimed at
the struts-dev list (or, now, the recently created [EMAIL PROTECTED]).
I'll stir things up over there and see if people are game for a new SNAPSHOT
build based on those changes.

Re: [s2] Struts Dependency Injection and EJB3 - support ? or how can i Do it?
While I have not used it, the Spring Framework provides strategies for defining Spring Beans which are EJB factories (or something like that.) Struts 2 works quite nicely using Spring as the Action Factory, which can take care of resolving all Action dependencies whether or not they are EJBs. See http://cwiki.apache.org/S2PLUGINS/spring-plugin.html for more on using Spring as your object factory and this Spring documentation on EJBs: http://www.springframework.org/docs/reference/ejb.html Hope that helps.

Re: combining chain of commands with struts action
It is unlikely that you need to use the ChainListener in a Struts 1.3.xapplication. First, you can have the ActionServlet instantiate all of your command catalogs by specifying the servlet init parameter chainConfig with a comma-separated list of classpath or servlet resources. Remember that if you manually provide this property, you must be sure to include the default Struts chain (org/apache/struts/chain/chain-config.xml) or one which establishes an alternate processing chain, in addition to any of your own which are used purely for per-request custom mappings. Once you've done that, you can use the catalog and command attributes of an action to cause Struts to invoke that command for a request instead of, or in addition to an action. (The command will be executed first if you specify both a command and a type.) You can count on your commands used in an action mapping being invoked with a Context which is actually a subclass of ActionContext and use that to access the request/response/mapping/form and the like which would be passed in to an Action's execute method. Please note that I don't think a whole lot of people have been using this feature, so you may well find bugs or even simply find that it could use some refinements. But this is the basic overview of how it's supposed to work. I hope this helps. Joe On 1/19/07, manunixx [EMAIL PROTECTED] wrote: hallo guys!

I'm no CSS whiz, but I don't think there's a way to do it just with CSS rules. Do I need to override the definition of the addError javascript method which actually puts the message in the HTML?

Re: [Struts 2] Database access
This example is for Struts 1.x, not Struts 2. Struts 2 provides no direct support for managing database connections, although one could achieve something like this rather readily using Spring, or probably with any other ObjectFactory. Here's a tutorial which gets much more involved than your basic request, but which might help. Note that since the tutorial uses Hibernate, it isn't exactly what you asked for, but it also demonstrates using Spring to instantiate a Datasource, and then you could have Spring also instantiate your Action Classes and inject the datasource dependency into them. http://cwiki.apache.org/S2WIKI/struts-2-spring-2-jpa-ajax.html Let me issue the standard disclaimer that if you are doing a lot of database work in your Action classes, you may want to consider refactoring anyway.

[S2-ish] deploying exploded webapps with maven2 and cargo
(I sent the below to the cargo users list, but haven't gotten a response in
several days, so I'm going to be gauche and send it to struts; now that
Struts2 uses Maven2, some Struts folks must be dealing with this [*cough*

I'm exploring the possibility of moving my webapp development team from
using Maven1 to Maven2 and one of the major practices we've developed has to
do with deploying our work in progress to a locally running Tomcat
instance. In the interest of not changing too many things at once, I'm
hoping to figure out how to use Cargo to do what we've previously had great
success achieving with the CodeCzar plugin.
I have found examples from various folks online indicating success with
this, but I am hitting a roadblock when I try to run exploded.
Everything seems to be fairly functional (if not quite straightforward!)
when I run from the WAR, but when I follow instructions from this post
(http://www.nabble.com/-mvnreloadable-webapps-t2762768.html#a7715823
) and add a location element to my deployable, I get the following

Any suggestions on how to dig more deeply on this? Below is the cargo
section of my effective POM. One thing which seems a little odd is that the
location element is only partially interpolated, although as seen in the
error message, it ends up fully interpolated by that point. So I don't know
if that is of any import or not.

Re: FRIDAY #2 non-MVC pages
When building a struts application, is it a good idea to base everything on actions? For instance, let's say I'm writing an 'About Us' page or 'Terms Of Service'... Should I build an action to handle them, or just write the JSP. My assumption is that it would be pedantic to have struts handle it, but I just want to make sure that there isn't some reason I don't see that I should struts-ify every page/action. In general, I advise using actions for everything, because you never know when you might need to intervene in the handling. It is a little tedious to have to deploy a new struts-config.xml for every new page; some judicious work with the wildcard based forwarding can eliminate a lot of that - set something up that automatically forwards to a JSP or a Tile based on the pattern match. Especially if you are exposing URLs that might get bookmarked, you don't want to have to change them later.

Re: Using Spring 2.0 - should I use Struts 1.2.9, 1.3.5, or 2.0?
I have not spent much time with Spring 2.0, but I doubt that the issues at hand are substantially different than with Spring 1.x. Struts 1.3.x is backwards compatible with Struts 1.2.x in most important ways (there's a Wiki page detailing issues.) However, depending on what parts of Spring's struts-integration libraries you use, you may find that certain Struts 1.3 features are not available or do not behave as expected. Specifically, Spring 1.x provides a custom implementation of the Struts Request Processor. You can use Struts and Spring together without using it, but if you choose to use it, you must understand the issues I'm going to try to explain here. Struts 1.3 attempted a substantial refactoring of request processing so that custom functionality would be more easily integrated without running into the limitations of Java single-inheritance. People found that they wanted behavior that was implemented in two different custom Request Processors (usually the TilesRequestProcessor and something else) and had to wrestle with how to achieve that. Those of us who wanted to write reusable extensions to the request processing cycle had to consider extending both the TilesRequestProcessor and the base RequestProcessor, and if someone wanted to put in even more customizations, this quickly becomes totally unworkable. If you use Spring's custom request processors in Struts 1.3.x, you will lose some new functionality which is only implemented in commands which are part of the new ComposableRequestProcessor's command chain. This mostly has to do with other uses of the commons-chain integration (like per-action and per-forward command execution), but also a little bit with the exception handling, where Struts now handles exceptions a little better when they occur in the midst of tiles. Struts 2.0 doesn't even use the same RequestProcessor, and I'm sure that the Spring folks haven't tried to write integration code with either Struts 1.3.x or Struts 2.0 since they've only recently seen full releases.

At 11:16 AM -0500 10/5/06, Paul Benedict wrote: I use Spring 2.0 with Struts 1.3.5, and employ the legacy RequestProcessor because Spring supports auto-wiring action classes with it. That's an invaluable feature to me. So, then (as expected), Paul's experience demonstrates that it works -- the point is mostly that whatever future changes happen in Struts 1.3, you can expect that gradually some things may be documented as working which wouldn't work in this case. We can certainly try to point out those cases, but the goal is for the request processor to be invisible to most users, so it will be a challenge to balance clarity with completeness. (Isn't it always ;-) ) Also note that it is entirely possible to set up custom commands and introduce them into the Struts 1.3.x request processing chain that do what the Spring autowiring request processor does. It's a little more awkward than I'd like to add in custom commands, but we have done it on a half-dozen apps already. We probably won't add that Spring integration code to Struts 1.3.x since we don't otherwise have a Spring dependency. I don't know if the Spring team has given any consideration to adding it to the Spring distribution now that we've made a GA release.

When I understand this right: - Giving Actions a state using Spring makes no sence Not so much makes no sense as doesn't get you anything. At least, once you are used to writing threadsafe actions, you don't see as much value. The value of request-scoped, stateful actions comes with a design like that used in WebWork and Struts 2.0, where the request parameters are used to populate properties of the Action itself, instead of being wrapped in an ActionForm and passed in. - It cannot be recommended to overwrite the request processor with Spring (we already have our own) This isn't quite true either. If you're using Struts 1.2.x and Spring, there's no reason not to use Spring's DelegatingRequestProcessor or DelegatingTilesRequestProcessor -- especially since they set you up to use the IOC (see below). The issue is only if you are using Struts 1.3 (or Struts 1.2.x with the struts-chain library) -- in this case, since you can only have one RequestProcessor, using Spring's will interfere with using the one which uses the Chain-of-Responsibility for handling the request. However, if you look at what the DelegatingRequestProcessor does (remember, this is open source!), it's not hard to write your own replacement for the SelectAction command that provides equivalent functionality. - But the spring Context offers some new possibilites like IOC but to be honest I'm not expert enough to understand this up to date! This is the Spring feature that I appreciate the most. Before we started using Spring, it was always awkward to make sure that your Action classes had references to business support and persistence manager classes. While there are plenty of solutions, all of them looked clumsy after we saw how we could use Spring to inject those dependencies into the action classes directly. Thanks I watched this example of IBM with the interceptor. Which other business-cases (aspects) could you reasonable use this way? Isn't this a performance problem, because interceptors always have to use refelection? Reflection performance has been markedly improved since earlier editions of the JVM. Struts already uses it all over the place (specifically for ActionForm population on every request, plus a lot of stuff at initialization time.)

Wendy gave you the right pointer. Note that the Spring custom RequestProcessor which is part of the strategy pointed out in the article Wendy referenced is not really good to use with Struts 1.3, because it doesn't use the chain of commands, and so some Struts 1.3 functionality would not be available. However, also note that with Struts 1.3 you could also just change the behavior of the CreateAction class so that it doesn't cache actions, but instead instantiates them anew for each request. In fact, if there were much interest at all, it would be easy make this a configurable option in the Struts core. (Alas, the way chain configs work, actually configuring it is a tiny bit more work than it should be, but not all that bad, and we could probably think of some other ways to express your intention without requiring a custom chain-config.xml -- perhaps a property on ActionMapping and/or a default setting?) Are there other arguments for using Spring with Struts like, for example an easy implemented Interceptor that might improve the application and is not as easily achieved with a filter? Totally aside from managing the instantiation of Action classes, it's extremely valuable as a mechanism for externalizing business services so that your controller code can be as light as possible. We've simply found that it makes using best practices a lot easier. We used to use Struts PlugIns, which are a functional way to initialize business services for actions to call up, but Spring can provide the same sort of model scaffolding much more cleanly. With a little study of Spring's advanced application configuration mechanisms (with layered application contexts and such), you can design your application so that you have a core of Spring config that is just as easily used by offline, non-webapp processes as it is used in the webapp; this was a real revelation to us for writing things like offline batch processes, where we used to struggle to maintain equivalent application configurations in the webapp and outside.

Joe How do you handle the population of the contexts which are passed to the jsp to which you are forwarding? ... Is there a reason you don't use the two action (setup and submit) approach? The reason I don't is because I know that the original design of the RequestProcessor didn't expect there to be two passes through in a single request, so that it's possible (in theory) for some values to be in unexpected state. Having known that, i've just developed design strategies which don't require chaining. We use Tiles in every webapp we do, so I have often used Tiles Controller classes for view population; I've also designed a few strategies implemented with changes to the RequestProcessor (or with custom chain commands since struts-chain) -- but none of which I felt were clearly something which should be committed to Struts proper. I know for a fact that many people have used action chaining (and I have at times too) and it hasn't been a problem.

Hope that helps Joe I'm in the process of learning webwork and while i'm at it i'm trying to decide on best practices for action architecture. Webwork makes the two action thing even easier, because you can specify a method to call on an action class in the action mapping, so the setup and submit handling methods can exist in the same action class. or you can even specify the method to call on an action class in the url using the ! character, as in /customer!setup.action.

Re: Dynamically adding form beans in plugin
Eamonn: The plugin gets the specific ModuleConfig for the module in which the plugin element appears. If you want to perform a certain setup operation in several modules, then each of them should repeat the same plugin element (or as close to the same as is appropriate.) If you only put the plugin element in one struts-config.xml, then it will only be initialized once, for that specific module. I'm not totally sure I understood your question, but if I did, hopefully this helps. We developed a library once that does something like this where it reads from a database to set up a form object.

Re: Action Framework: simultaneous requests on the same path, in the same session.
but I wonder if that's a good idea. Am I missing something here? Is there a way to ensure that the action is called each time with the set of parameters it was supposed to receive? If your forms are request scoped, there should be no problem; a new object would be created each time. If you must use session scoped forms, it's not so easy, as the token mechanism for dealing with double-posts is not automatic; you must invoke it from your action, which means that the population/corruption may have already happened. If you are actually using JavaScript to submit these forms, then I'd suggest adding some JavaScript which sets a submitted flag and tests it before actually causing a submit, setting it to true after it does submit. I think that in a single page (not frame), things should be single-threaded so that this is relatively safe. The other solution would be to extend the RequestProcessor to add a token validation step earlier than in the Action's execute() method. Actually, in Struts 1.3 this would be easier for all the reasons that Struts 1.3 makes changing the request processing path easier. You could make a validate token command which would check the ActionMapping to see if it had been configured to require valid token (probably using Struts 1.3's arbitrary config properties) and if that configuration had been set, you'd do the validation (which can be done using ActionContext), and if the validation failed, you'd probably fall back to using some other configuration property of the ActionMapping to determine the fallback action. It actually seems like something which would be useful to add to the Struts 1.3 core, and perhaps even into the default chain. Unfortunately, I don't have time to code up something like that this month, but if you're interested, I can at least try to field basic questions here on the list (and hopefully so can others!) The use of tokens in Struts 1.3 is probably something which could use a bit of a workout anyway; I can't remember why offhand, but I had some questions about how I adapted the processing model from Action to ActionContext and I haven't had an opportunity to really give that a workout myself.

In a document from the struts university (author Ted Husted) is an

In the nightly builds and in the newest subversion branch (366511)
there is no getProperty() method

The properties are set on the ActionMapping, not the Action class.
So in this case you'd use
String foo = mapping.getProperty(foo);
Hope this helps

Re: how to set token after an exception occurs ?
At 3:03 PM +0100 12/5/05, Nicolas De Loof wrote: Hello, I'm using token to avoid multiple submits in this flow : /commande.do creates an empty form-bean, saves a token and forwards to tile:commande.new /commande/create.do checks for token and creates datas in the database. If an exception occurs, an exceptionHandler is used to display an error message. I'm using it to catch Data integrity exception when user try to create an allready-existing entry. In this case, no token is saved anymore and user cannot change it's input and resubmit. How can I setup struts to have a new token beeing saved when an exception occurs, to allow the user to correct the form and submit ? The easiest thing I can think of would be to drop the declarative exception handling; catch the exception in the action mapped to /commande/create.do instead, where you can save a new token and return the user to tile:commande.new. Of course, you could extend the base ExceptionHandler, perhaps adding a configuration element that tells it to reset the token when the config is in a certain state. In Struts 1.2 you can extend ExceptionConfig and add arbitrary bean properties like you might with ActionMapping, and in Struts 1.3 ExceptionConfig participates in the arbitrary property-map model so that you don't even need to extend it. But I think that may be too much behavior for an exception handler. I am not inclined to use exceptions to route control flow. Joe Nico.

You might also want to review the DWR documentation on Converters:

In short, it requires you to show it how to marshall any object

Re: [FRIDAY] Struts 1.x is Struts Classic after all
Struts = Legacy Struts 1.2.x - Action based architecture Struts Shale = Framework that leans on JSF and has a compatability layer written so it can support 1.x Struts apps This is not correct. Struts Shale does not have a compatibility layer for Struts 1.x apps. There is struts-faces, a library which provides some support for using Java Server Faces with Struts 1.x apps. There is Struts Ti, a framework which will probably provide some kind of compatibility layer with Struts 1.x apps. From a marketing perspective it's a bit untidy. It would be better if Shale were it's own project, not tied to the Struts name and Struts core was allowed to ride off into the Sunset. This would be less confusing to the business decision maker, I believe. Hm. Is it untidy that the Apache Software foundation has at least three web application frameworks? Should they be untethered from the Apache name and allowed to ride off... ? For that matter, why does Apache clutter itself with anything other than the original httpd? Decision makers out there are trying to figure out what to do about Microsoft Vista, or that Apple is releasing Intel-based Macs next year; there's always something. Decision makers can choose to sit and wait for things to clear up, or they can make their best educated decision about something now. For that matter, a decision maker could decide to commit development resources to an open source project, so as to have some control over its direction, and thus improve their ability to be confident in the decisions they have made.

Joe, I like your philosophy :-) My question is why is Shale under the Struts banner? As far as I see it, it has nothing to do with the Struts community, minus the creator. That's not true; there are other committers who have done work under Shale. It's not even a revolution. It addresses a wholly different problem set and I think it's wrong to call it Struts. Imagine, as an analogy, the brouhaha if Tapestry suddenly began calling itself Struts Tapestry because it's a framework too! I think Struts Shale wholly confuses the brand name. I'd like to see it be it's own man -- call it Jakarta Shale or Apache Shale. And either of these might happen some day. In the meantime, what trouble is it to you? Why don't we hear any sniping about the project to wean Tiles from having dependencies upon Struts? It is similarly at the periphery of struts-core. What's the big deal? I know this thread has [FRIDAY] written all over it, but there's all this other sniping about Shale that doesn't. Why not leave it be and put your (collective) energy towards building something you want to use instead of kibitzing about something you don't? There are plenty of open tickets for Struts 1.x, a world of discussions that can be had about moving Struts Titanium forward, and a handful of other web applications that probably need volunteer efforts as well.

That Shale has an Ajax module has nothing to do with DWR; DWR provides all of its own AJAX plumbing, if by AJAX you mean having a page communicate with a server without a full page refresh. (The other facet of behavior commonly lumped under AJAX is DHTML effects; DWR has a small util library for those but doesn't really try to serve that space.) Frank's pointer to the DWR site hits the button, I think. If you have designed your Struts application correctly, then you can easily use DWR where you need to, but DWR has no need to know anything about Struts at all. You would have two servlets in one application context sharing access to the same business-level components. If you have so much behavior bound up in Struts Actions and ActionForms that you can't easily use DWR in the same application context, then you have too much behavior bound up in Struts. Time to refactor! We're using DWR on my most current project to very nice effect. I heartily recommend it. I wouldn't presume to make security recommendations for a banking application, but DWR seems to have a pretty good handle on basic security issues, in that it only exposes the things you configure for exposure, rather than automatically allowing things.

Re: How do you prepopulate your forms?
This is essentially the standard approach. Your code leaves out the possibility that the form already exists (and that it may be in the session scope). This may be practical for your cases, but might lead to confusion should someone change part of the flow in your application. In Struts 1.3, there are actually a few places where this basic operation (check a scope for existing form, if not found, create it and place in scope, and return either pre-existing or new form) are done. I haven't seen a path to encapsulate it into one single operation, although I haven't actually thought about it for quite a while; it could probably just be put into a static util method on some class, but I was sort of down on static util methods for a while. Anyway, Struts does this for you in the CreateActionForm class. This isn't appropriate to prepopulation, though. If you want to do it yourself, there are two ways to get at it, but both involve newer features of Struts 1.3. First, and probably best, would be to use the CopyFormToContext command as part of a chain of commands; it can actually do the lookup so that all you have to specify is the path of the destination action and it will look up the form name and scope, much as html:form does. This provides for clean configuration. You can make a chain which uses this command and then has a subsequent command retrieve the form from the context and do the population. This behavior is also implemented in the ActionContextBase class, in the method findOrCreateActionForm(String formName, String scopeName). This method is not part of the ActionContext interface. Perhaps it should be, but I thought it best to figure out a way to put this code in one place rather than three before adding it to the interface. Still, if you have an ActionContext instance which inherits from ActionContextBase then you can cast and use the method. However, at this time a typical Struts Action class does not have a reference to an ActionContext object; we have not yet committed to changing the Action interface to receive one, and we haven't yet settled on a potential place to offer static access to a ThreadLocal which might store the ActionContext, although I'm using this basic pattern in a custom implementation of ActionContext and finding it workable, and there was some interest in having this last time it came up on the dev list. I've seen people using the input attribute point to an prepopulate action? the input attribute is only used when form validation fails. In some approaches, some page prep needs to happen here, although what I usually consider prepopulation (seeding with persistent values) is not relevant because the form should be refilled with whatever was submitted in the HTTP request. However, if you have dynamic menus or other form elements, of course you need to arrange for those to be restored.

Re: 1.3 Struts Validator Plugin Bug
By default, Struts expects a path as the value to input, not a forward name. You must explicitly configure if you prefer to use the forward name. See http://struts.apache.org/struts-core/userGuide/configuration.html#controller_config, specifically the inputForward attribute.

If I submit it with no form values filled in, then I get the following exception: java.lang.IllegalArgumentException: Path input-form does not start with a / character The reason? The action's input attribute is set to the value input-form. This simply references the forward named input-form, just like the example. But the validator plugin errors out because the input-form does not start with a /. Changing the input attribute and forward name to /input-form does not help because it then tries the literal URI /input-form and I then get a 404 with: The requested resource (/input-form) is not available. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Joe Germuska [EMAIL PROTECTED] http://blog.germuska.com Narrow minds are weapons made for mass destruction -The Ex - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

org/apache/struts/resources/struts-config_1_0.dtd
org/apache/struts/resources/struts-config_1_1.dtd

org/apache/struts/resources/tiles-config_1_1.dtd
org/apache/struts/resources/web-app_2_2.dtd
org/apache/struts/resources/web-app_2_3.dtd
In other words - the tiles-config DTD is not referenced. This means
that for a project using tiles installed on a box that has no access
to the web - the resolution of the tiles DTD fails.
Is this by design? Or should the DTD be added?
If by design - how best to get the tiles DTD to resolve on boxes that
have no net access? At present I appear to be creating a descendent of
ActionServlet where the only difference is that in the init method
adds the tiles DTD - is there a better way?

Re: Adding images to option items in a select drop down list

Here's an example of something a user might not distinguish from what is described, although it wouldn't be using select http://script.aculo.us/demos/ajax/autocompleter_customized By using DHTML like this and having an event cause a hidden form field value to be set, you could achieve the goal. Note that Scriptaculous builds upon the Prototype library, which breaks commons-validator client side javascript validation.

Re: So boring issues about character encoding in action ......
At 1:44 PM +0800 10/18/05, Tony Lu wrote:
I need to create an internationalized Web application by struts,mysql and
hibernate.
Each component Character Encoding is utf8.
It runs well when I run a pure servlet to save 'Chinese Character' to
database and load it from database.
But when I implement it with struts action, the application can not save
Chinese correctly.
I really don't know why struts action can not work well. I am sure there is
no difference between them.
By the time that your action class is executing, Struts has already
read from the request input stream (to populate the ActionForm).
In any web application, if you want to set the request character
encoding, you must arrange to do it before any code will read from
the request input stream. The best way to do this in a Servlet 2.3
or later web environment is to use a ServletFilter. In fact, most of
the worked examples of writing ServletFilters on the web are to solve
this problem.
You could also do it by extending RequestProcessor (or
TilesRequestProcessor, if you use Tiles) and overriding the
processPreprocess method. However, in Struts 1.3 the
processPreprocess method is no longer used. Using a ServletFilter
will apply to any application you write in any Struts version, or
with a non-Struts approach.

Is there anywhere to set character encoding for action? Please help!
--Pure Servlet ( It runs well)
-
public class UtfTest extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
request.setCharacterEncoding(UTF-8);
String description = request.getParameter(description);
description = (description == null?:description.trim());
try{
ItemDAO itemDao = ItemDAO.getInstance();
Item item = new Item();
item.setDescription(description);
itemDao.save(item);
}catch(Exception e){
e.printStackTrace();
}
response.sendRedirect(test.jsp);
}
}
--Action for struts
public class TestAction extends Action{
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest req,
HttpServletResponse res) throws Exception {
req.setCharacterEncoding(UTF-8);
String description = req.getParameter(description);
description = (description == null?:description.trim());
try{
ItemDAO itemDao = ItemDAO.getInstance();
Item item = new Item();
item.setDescription(description);
itemDao.save(item);
// Determine which action forward should be returned
return mapping.findForward(success);
}catch(Exception e){
}
}
}

Re: errorStyleClass with ActionMessages
At 3:26 PM +0100 10/17/05, [EMAIL PROTECTED] wrote: Hi there, I would like to make use of the errorStyleClass functionality with validation errors that I create in my action class using ActionMessages. I guess there must be a way of letting the ActionMessage object know which UI field it is relating to. Has anyone managed to do this without creating custom validation controlled by validation.xml? When you add an ActionMessage object to an ActionMessages collection, you must specify the property with which the message associates. This string should be exactly the value in the property attribute of your form element in the JSP.

Re: Custom Struts code or 1.2.8?
At 9:17 PM -0700 10/13/05, Paul Benedict wrote: Does anyone ever run any custom versions of Struts or the Commons library? The reason I ask is because the bug that I need fix (it is now fixed) in Commons Validator isn't released for the Struts 1.2.x branch, but most likely will be released with Struts 1.3 Well I don't like using release 1 of anything :-) I wouldn't want to upgrade to Struts 1.3 until it at least gets into version 1.3.3 or something - the theoretical risk for large bugs is high... Just think of how many releases were for Struts 1.2! Yes, but think of how many applications are in production right now built on Struts 1.1, or on Struts 1.2.[x7]. Most of the changes from version to version of Struts are feature enhancements, and most of the bug fixes clearly don't prevent most people from building applications that operate perfectly well even while the identified bug has not been fixed. My team and I have put three Struts 1.3.x webapps into production so far, and we're working on more all the time. I'm certain it's possible that there are bugs in there that just haven't been exercised given some particulars of how we write webapps, but it's not like it was rewritten from the ground up. So what's the right solution here? I would like to see a Strut 1.2.8, as I said, with an upgraded Commons Validator too. Do I just compile a custom version of Validator for myself? I'd like to hear opinions. If this particular bug is in commons-validator, then why do you need a different version of Struts? Sorry, I haven't been following the validator development extremely closely, but if the bug isn't in Struts, why is the release version of Struts a concern? Struts, as with most open source code, doesn't go through the kind of testing process prior to a versioned release that you might imagine if you are thinking of commercial software. I don't know if that clarifies anything or not.
