newbie question from expierenced user

[Marcus Biel]

Hi there,

I working with Struts 1.02 quite a while now,
and did a very complicated application using Struts,

but the more I know, the more I realize that I don't exactly know the
basics:

What exactly is the difference between the different scopes & which
scopes are there,
besides request, session & page ? When to use whichsoever scope ?

What if I am using one form for different actions, using different
scopes ?
Could it be that that creates different ActionForms in different scopes
of the same type ???


thx in advance,

marcus

RE: Commons-logging and JDK 1.4 Logger

[Wendy Cameron]

So let me get this straight:

I sought of got it to work however as usuall its coming out in the console and not 
where I want it to go and at a level INFO.  

I want to have one log file for the whole application at the moment.
I also want the same level of detail for all classes.

At the moment I cant figure out where to put things like

java.util.logging.FileHandler.pattern = C:\\inMotion\\logs\\java%u.log
java.util.logging.ConsoleHandler.level = FINEST

in the jdk logging.properties or in the commons-logging.properties in the WEB-INF
or is it supposed to go somewhere else.
Cause it doesnt seem to work from in the web inf directory at all

Basically my code for doing the logging seems okay, I just can seem to configure the 
logging process.

Re: Managing a workflow with Struts-workflow.

[Matthias Bauer]

Hi Olivier.

Let me first say this: The workflow extension is not meant to help you 
manage session data and dispatch actions depending on that session data.

Instead it can force the user to follow a sequence of actions that he is 
not allowed to leave. For example think of modal dialogs that are well 
known in desktop gui applications. There you have to click on a button 
the dialog offers before you can do something else in the application. 
One thing that makes web applications more difficult to handle is the 
fact, that you can not rely on a certain request being the next one, 
because the user can alway type in a new url or use the back or reload 
button.

Let's turn to your problem: It I get it right, you do not want to 
"punish" the user (e. g. by displaying an error screen), if he leaves 
this wizard like application. Instead you want to dispatch him depending 
on the data he has already filled in.

What I would recommend to you is this:

- keep an ActionForm in the user's session that collects all the data 
the user has filled in
- in the action form you also keep the  state information which step has 
to be executed next (step1, step2, step3)
- create a wizard-dispatcher that decides where to forward to (depending 
on the state information)


This would look like this:

MainPage.do -> dispatch.do -> 1.jsp -> submitFirstStep.do -> 2.jsp -> 
submitSecondStep.do -> 3.jsp -> submitThirdStep.do -> result.jsp

If someone executes dispatch.do when already having executed 
submitFirstStep.do the state information would be "step2" which results in
-> dispatch.do -> 2.jsp -> ...

You don't have to hard-code the urls into the dispatch action. Instead 
you just need to define forwards for "step1", "step2", ... in the 
struts-config.xml. All the dispatch action does is finding the right 
forward.

I think this is very easy. You don't need an additional framework for 
that...

I think each Step will test if the part of the ActionForm
it handles is already filled (then the current step must be skipped), 
and if so, it forwards to the next action.

Is it the good way to do the job?

I am not sure to see the benefit of using the workflow plug-in.
I declare the workflow in my struts-config.xml, but still have to hard 
code next/previous URLs in my JSPs.

The benefit is of course that the workflow detects if the user
broke the natural chaning by clicking several "Back" in his browser.
But if he did, he could have some reasons, and this may not be an error.

Well, I am sure I misunderstand something, but any help is welcome.

Clear chosen value from form bean

[Mohan Radhakrishnan]

Hello,
  Problem : Is there a way to clear the chosen value from the String[]
in the form ?

  We have the same form for many screens. After the user chooses from
the drop-down and submits, the chosen value is highlighted. But the user
should be seeing a clean drop-down everytime.

 Solution : I set scope="request" in the config. file

  So this means that a new form bean will be created every request ?
Performance implications ?
Thanks,
Mohan

This just says where the log messages go -- not what should be logged.  If
your logger is named "com.foo.MyClass", you'd need to add:

  com.foo.MyClass.level = FINEST

or, if you wanted trace output from all the classes in the com.foo
package:

  com.foo.level = FINEST

For more information about configuring JDK logging, see the JDK
Documentation Bundle -- it's got an article specifically about the logging
features.

One other note -- the JDK logging properties are only read when a
particular JVM first starts using the logging calls, so you'll need to
restart Tomcat to make any changes take effect.

Well actually a few more stupid questions cause it doesnt work yet :)

I have created properties file with the following:

org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.Jdk14Logger
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Jdk14Logger

Placed it in WEB-INF directory and I have a debug statement in my code

log.trace("init( " +  actions + ")");

in my j2re\lib directory if logging.properties
java.util.logging.FileHandler.pattern = C:\\inMotion\\logs\\java%u.log
Is this necessary or is this controlled by:



in the context declaration in the server.xml?

any suggestions?

I post this message because I did not found any doc about the
createToken, isTokenValid, resetToken API.
So I will explain what I understood about it from the struts-exemple
if something is wrong, I would like that someone will say to me
and if there is some doc tell me where ...


The token API is created to avoid that the user
to submlit twice the same form.
It is used with one ActionForm and two Action:
- the SomethingForm which contain the user's input
- the EditSomethingAction which populate the SomethingForm from the DB or
  clear all the field if it is a create Case
- the SaveSomethingAction which save the SomethingForm in the DB

To avoid that the user call submit twice the SomethingForm and
save twice the same data in the DB,
the struts framework propse the xxxToken API.

It is used as following
in EditSomethingAction, make a call to createToken(request) and that all !

in SaveSomethingAction, make a call to isTokenValid(request) and
resetToken(request)
as in the following  algorithm
if ( ! isTokenValid(request) )
{
/*
 * return forward towards an error page
 * saying to the user that he has submit twice
 * or
 * forward toward the succes page if we don't want the user see anithing
 */
}
else
{
/*
 * process the save in the DB
 */
if ( allTheSaveHasSucceed )
{
resetToken(request) ;
}
}

You much take care that there is only one token in the session
so that this process can't support nested transactions.
So you should keep simple use of it.


The same API can be used to avoid that the user click twice on
a link by setting the 'transaction' attribute at "true" of the 
tag
the Action called by the link should follow the same process than
SaveSomethingAction

Hi.

The struts transaction token prevents that users klick the back-button in
the browser. Some Applications , e.g. workflow driven apps, can not deal
with back-buttons, because it may be, that a database transaction is
fullfilled, and there is no chance for a rollback.

The method saveToken(request); called in the execute-Method (Struts 1.1) of
the action saves the token. At the next action you can look, if the token is
already valid.

if (!isTokenValid(request)) {
// error
}

With the method resetToken(request); you can reset the token.

The mechanism is quite tricky: The  tag reads the token out of
the session and writes it in the request. So if someones goes back (browser
back) the form responds an old (a different) token. If you not deal with
 some tags has a attribute transaction, that you can switch to
true.

Very fine mechanism, really

Sorry ... it the send key by accident ...

The browser shows the ".do" url because it has no clue you did a forward.
If you really need it to change, you'll need to use a redirect instead of
a forward, which costs you a *lot* in terms of performance (extra round
trip to the client) and flexibility (cannot use request attributes to
forward information to the page).  Usually, it's better to train your
users that the location bar is totally irrelevant in web applications

The same way Struts 1.1 classes do it would be good :-).

  import org.apache.commons.logging.Log;
  import org.apache.commons.logging.LogFactory;

  ...
  private static Log log = LogFactory.getLog(...);

RE: Is Struts (or browser based applications in general) useable to build maintenance-applications?

[Edgar Dollin]

Quite correct, I (and somewhat reluctantly the user base) have accepted the
limitations of the back button.  There is no risk to the database however.

I give users as many of those links you describe as possible but only to
informational pages, and with container managed security (or filter based
security) they maintain some of what the users desire for flexibility
without sacrificing application integrity.

Interesting commentary.

Thanks.

Ive a quite lot of links that look like
"thingAction.do?method=edit&uid=1234". As I go along Im rather coming to the
view that I should just try and use POST for everything and eliminate GETs
altogether. The browser just takes far too many liberties with them...

The sequencer idea has merit (seems similar in concept to the token token
support struts already provides), but the problem is that they want the damn
back button to actually work. Given that the app needs to maintain fifty
tons of state (including state of various ui widgets, workflows and other
wierdities) to meet all the other requirements its very hard to figure out a
suitable way to handle this short of incorperating a TARDIS in my
application.

The basic problem of course is the app vs website dilema. In a website the
back button is very useful as your just navigating round a bunch of
relatively stateless pages and a request is a direction for which page you
want next. In a web app however you arent navigating round a bunch of pages,
but rather firing events to the server that cause changes in server state
which are reflected in the response page. Clicking the back button would
cause the last 'event' to be fired again, or a snapshot of an earlier
response page to be shown, but the server is already in a different state.
The last event was already processed. Database writes have been commited.
Objects created or destroyed. Widgets toggled and workflows woggled.

Keeping a token gives you a chance to tell if the user is submitting from an
earlier page cached in the browser, and you can show an error message and
perhaps even direct them back on track - but when your requirement is that
that old page work again just like it did before, its nearly impossible. It
will work in some cases, but in others you can end up with all sorts of
problems if there are things that depend on server side state as well as
client side state - and in all but the most trivial of cases this will be
true. What to do?
:-(

Its hard enough to try an explain this problem to the (more experienced
technical) people who give me these requirements. I hate to think how the
concept can be imparted to users...

I have resolved all my Web Application issues (it did take a while).

The back button can be solved by subclassing the ActionForm and having a
standard sequence field.  In all your JSP make sure there is a hidden field
for the sequencer.  Then before any action occurs (write to the db) check
the sequencer to make sure it is the value expected.

If you only use POST methods in JSP the bookmark issue is moot.

Hope that helps

On the positive side, your users wont need to install a client application

In addition a lot of things that require tons of code in Swing can be
achieved relatively easily from a browser UI. (For example printing a fancy

RE: delay user input validate....

[Vipul Sanghi]

I think you can achieve this by doing the following:

1.  The Form bean has to have elements of all the parameters of the User
registration (screen 1 and screen2).  This formbean has to be of session
scope that is how you can delay the validation of the input till the second
screen.
2.  The action on the screen1 should not have any validation, it should also
not commit the bean but just forward to screen2 (forward action).  The
action on screen2 should have all the validation you want.  then depending
of the type of error forward either to the screen1 or screen2.

PS. One intutive approach to satisfy your business requirements could be to
save you some headache is on screen2 after the user presses (Save/Done)
display the fields from screen1 and screen2 with errors.  So you would not
have to do any custom forwarding on errors and just have to put an if
condition for the portion of scree2 which has screen1 elements to only
display when there is an error.

Hope this helps.  We have done something similar.

Subject: delay user input validate


Hi, All:

I have a problem related to user input validation. I searched on the web, it
seems that I couldn't get a clue. Hopefully, you can help me out.

I have two screens: screen1 and screen2. The two screens are used for new
user registration.

On screen1, there are three fields: userName, password and confirmPassword.
There is also a "Continue" button on the screen1.--Validation rule:
userName should be unique. password and confirmPassword should be same.

On screen2, there are user imformation fields, such as street, city, etc.
And there is a  "Submit" button.

When user click on "Continue" on the screen1, the screen2 will be displayed,
even though there are input errors on screen1. The validation of the input
on screen1 will be delayed until user click "Submit" button on screen2. If
one(or all) of the fields are invalid (on screen1), the screen1 will be
displayed with original input, plus relevant error message. If there are
also error messages on screen2, their display should be delayed until the
user fixed the errors on screen1, click "continue" to go to screen2(fields
on screen2 prepopulated with original input) clicks "Submit", in this case,
controls back to screen2 with error messgaes and pre-entered data.

The above senario is business required.

How can I achieve this using struts(1.1.b). I know in struts, we can use
actionForm, validation, struts-config.xml, and etc. But how should I combine
them together to acheive the above senario. I really need your help. Thank
you in advance for your help.

Sincerely,

Doug

Tiles - definition="main.Layout" What does this means?

[aps olute]

 I just started with the Tiles tutorial and got stuck at this
definition="doc.mainLayout"  on the index.jsp, what does it mean? I see similar
definition="mainLayout"  under tutorial/index.jsp. I looked in the 
tiles-tutorial-defs.xml and found a definition for mainLayout but none for
doc.mainLayout  where does it find it?

struts-1.1-b2 nested tags don't work with tag handler pooling(tomcat-4.1.12)

[Lenny Marks]

The struts-nested tags from struts-1.1-b2 don't work when tag handler pooling
is used. Tomcat 4.1.12 has pooling turned on by default.

This can be demonstrated by deploying the 'MonkeyTree war (milestone two)'
from the Tree Structures tutorial by Arron Bates into tomcat-4.1.12.

Tutorial at:
http://www.keyboardmonkey.com/pilotlight/index.jsp
http://www.keyboardmonkey.com/pilotlight/monkey-tree/wars/monkey-tree_02/monk
ey-tree.war

Make sure pooling is off. See enablePooling in $CATALINA_HOME/conf/web.xml.
Also note that compiled jsp's in the $CATALINA_BASE/work directory must be
removed and server restarted to see new settings take effect.

==

*With pooling off:

Monkey Tree
monkey one
 monkey two
monkey three
 monkey four

*With pooling on:

Monkey Tree
 monkey one
   monkey two
 monkey one
   monkey two

I haven't checked the struts code, but I think this might be related to Bug
13392(When tag pooling is enabled, release() is not called on tag instances)
in the Apache Bug Database. This ticket ended up 'INVALID' referring to the
semantics of the release() method as defined by JSP.10.1.1.2 (JSP 1.2).
Apparently tags that depend on the release() method to reset state are not
spec compliant.

*** My Question?
Are the struts-nested problems related to the above, and if so, can they be
fixed to be spec compliant, or is their use dependend on deployment within a
servlet container that does not use handler pooling?

The semantics of tag handler reuse seem to be a bit ill-defined. It is well
stated that a tag handler instance can be re-used within the same page
request as well as across page requests. It is not clear whether the
release() method is gauranteed to be called after all reuse within a single
page, or only before the handler is released to the GC(all pages).

See. Web Development with Java Server Pages Second Edition(Manning) pg. 553
which says it will be called after all reuse within a page.

Professional JSP 2nd Edition(Wrox) pg. 301
(After page)

When you use container managed security, it is imposed *only* on the
original request URI, *not* on the URIs used in a
RequestDispatcher.forward() method.

Did you say you're running Tomcat?  If so, this shouldn't be too
surprising, since Tomcat does not support EJBs.

In 1.1, Struts and all the commons libraries it employes use
commons-logging as an abstraction to the underlying logging system -- in
turn, this allows you to use a variety of logging implementations such as
Log4J, JDK 1.4 logging, or a simple write-to-System.err default
implementation.  The actual configuration of the logging is done with the
configuration file for your logging mechanism (for example, to set up JDK
1.4 logging you edit <$JAVA_HOME/jre/lib/logging.properties>.

To configure *what* gets logged, the important issue is to understand the
default log name conventions of Apache code (typically the fully qualified
class name of the corresponding class).  Also, the typical logging
configuraiton file is hierarchical -- so that you can say things like this
to set the usual Struts logging levels to INFO, but get detailed debug
info from RequestProcessor (uses JDK 1.4 syntax):

org.apache.struts.level =INFO
org.apache.struts.action.RequestProcessor.level = DEBUG

Check the docs for configuring whichever logging implementation you want
to use for how to configure levels by logger name.  For the simple default
logger, it's in the package description at:

http://jakarta.apache.org/commons/logging/api/

Hi!

This is a little off topic:
I just wrote a struts app (Tomcat 4.1.12, Struts 1.1b2, Tiles, JDK 
1.4.0_01, Win2K) that unfortunately crashes Tomcat after a while with 
an OutOfMemory Exception. So I assume my app has a memory leak.

Does anybody have a hint on how to find memory leaks in a web app?

You can send them to a different machine, url, etc.  But, sounds as if you

RE: Easy Question

[Karr, David]

It appears you have an exception handler for HTTP error code 500 which
is hiding the stack trace.  Check your server logs to see if it got
logged somewhere, or try to remove the error code exception handler.
The "root cause" of the exception is probably important.

I would guess this application is trying to connect to a remote EJB
server?  You'll have to get the EJB api jar file into your WEB-INF/lib,
to at least get access to the class files.

Re: Communication Between WebApps

... looked into container-managed authentication yet?  Tomcat (and 
others, I believe) will let you do single sign-on among different apps. 
With CMA you don't have to worry about how the authentication gets 
invoked ... the container takes care of that.

Hey
The jar file, called iNDemandCH.jar lives in this directory.
C:\Tomcat\webapps\indemand\WEB-INF\lib
the weird thing about this is that some .do actions work, and others don't. Do you 
think it might be that it can't see the class files?

Re: request to struts action not being routed to J2EE container security

[David Graham]

Instead of using the sendRedirect method you should just define the forward 
element in struts-config with redirect="true".  That way you can still use 
the logical names and not code b.do in your action.  Struts will redirect 
for you when it sees that attribute set to true.

That worked like a champ. I did not know that forwards were not redirected
through the user.
Here is the code;

if(user == null) // no user was found in the session or
authenticated request.getUserPrincipal()
{
response.sendRedirect("/webapp/consumer/b.do");

Re: request to struts action not being routed to J2EE containersecurity

[Eddie Bush]

Are you forwarding to /consumer/b.do?  If so it won't make the user 
authenticate - you need to redirect.  Your application is able to send 
the user anywhere - CMA only protects you from direct-access by the user 
(which is the situation you get by doing a redirect).

If you're doing a redirect and this doesn't work, I'd say your server is 
broker.

Michael Lee wrote:

Problem is a.do is calling b.do and no redirect to the login page defined by the form based security in the web.xml takes place!

I was thinking about calling weblogic specific weblogic.servlet.security.ServletAuthentication class to explicitly load the user into the container security upon successful completion of a.do but I would prefer a non-container specific implementation.

[OT]: Finding memory leaks

Search google for profiling tools.  You're probably holding onto old objects 
in a Collection so they never get garbage collected.  You're probably not

Hi!

Re: [OT] Updating CachedRowSet

[V. Cekvenich]

RowSet does not do Multi Table Updates! Neither does CommonsSQL as I saw 
it. That is why it's light weight, fast and scalable, since it does not 
deal with O/R, it is just relational data. For R/O, you can do joins, 
most data is R/O. Also, if you do use RowSet, do not use ResultSet, no 
need for it. (The reason I use Struts is that is is light weight and 
fast, thus I avoid heavy DAO layers that do not do SQL (ex: EJB, JDO, OJB).

For R/W:
But of course one can do master/Detail, or many to many, or more 
complicated updates, in fact most updates are "compound". See if I can 
explain this, but it takes using the tool between the ears:
For multi table updates I create a nested bean. Master/Detail like.
I always start by creating base beans, simple beans that are unit 
tested, and have a dao, but have a singe table.
Then I created a C bean that extends bean A, and has a bean B. (is a/has 
 a is very OO **)
Bean C has 2 tables now. (you get the idea?) It has a B getB() method. I 
override next (for iteration) to go next on the A and B, find  {to do 
super.find() (for A) and B.find for b }, save { super.save(), B.save() 
}, etc.
With this Zero copy approach, I can get very high transactions rates for 
low overhead. Compare this to multi copy and ineficient aproach of array 
list of objects when you need to do updetable master detail processing.
Why is this Zero copy? Because the cached or disconnected row set, where 
the retrieval happens, is where the setters fire. (Advanced: My beans 
are actually collections with getRow so they can do multi row updates, 
but  they look like regular beans).

I can change DAO implementation at will as well. I can use same bean in 
console, or Model 1, or Soap, etc. since DAO lets me create a DBCP pool 
or use the pool of the container (based on properties).
My Beans of type C are tied to the presentation layer.

OT: (Since my beans of type C are tied to the presentation, I do 
presentation first on my projects as a "contract" with 0 code until the 
presentation layers is accepted and signed of by a client.
The presentation just has actions that forward to "success", nothing 
else, maybe some other navigation logic.
The JSPs the client sees look real, as a finished app. It has tiles, and 
CSS, but no java code, no point in coding until the client signs of. 
Once the client says, yes, this is the what I want (Just blank actions 
and JSP) then I start coding the "simple beans" that I unit test. Then I 
create the bus. compound beans (is a/ has a) and unit test them. Thus I 
have benefits of layered iterative approach. The thing that I will be 
adding soon to "example app" , is more browser side procesing in XFORMS, 
and JavaScript.
Consider allways writing presentation and action mappings first in Model 
2, then beans come natural. That is why you do MVC layers, right, so you 
can unit test each!).

.V


** Some people do not realize that Java is OO capable.  Java does not 
produce OO reusable code on it's own, it compiles fine linear, but you 
could if you have experience make it reusable via OO. This lets me reuse 
beans, and other things.

Yes, in these cases, it would probably be quicker to manually check (from

If all else fails, blow away JBoss' work directory:

RE: ApplicationResources.properties not reloading added keys

[James Mitchell]

Yes, in these cases, it would probably be quicker to manually check (from your
source all the way to the deployed application) that the file exists and was
updated.

If all else fails, blow away JBoss' work directory:
$JBOSS_HOME/server/default/tmp/deploy/server/default/deploy/{yourapp.war}

Hope that helps.

problem with commons-collections.jar in struts 1.1b2

[Lloyd Meinholz]

I am having problems with the struts webapps. There seems to be some kind of
problem with the commons-collections.jar. I have built everything myself and
I think it all built correctly. Here's my setup:

gentoo Linux, Sun JDK 1.4.1-01, tomcat 4.1.12, struts-1.1-b2, most recent
commons code, specifically collections-2.1.

I'm really confused as to what has caused this error and any help is
appreciated. Thanks,

Lloyd

RE: ApplicationResources.properties not reloading added keys

[Alvarado, Juan (c)]

The way I'm working is as follows:

We have an ant task that will build an ear file.
What we then do is through some ant tasks, extract the ear file into the
deploy folder of jboss. Another task then extracts the war file into the
deploy folder also. So what I end up with is as follows:

$JBOSS_DEPLOY_DIRECTORY/$EAR_DIRECTORY
$JBOSS_DEPLOY_DIRECTORY/$WAR_DIRECTORY

Inside the $EAR_DIRECTORY is your typical J2EE stuff, and inside the
$WAR_DIRECTORY is the web-app.

Whenever I make a change to the properties file, I have an ant task that
will touch the web.xml of the web-app, but this doesn't work. Shutting down
and restarting jboss from scratch does not do the trick either. Pretty
weird

Thanks for the quick reply.

a) building .war and deploy/redeploy
b) changing the files in place (I don't think this is possible)
c) working right in the deploy directory

If a, are you sure you are not adding it to the .properties that gets

RE: [OT] Updating CachedRowSet

[John Bigboote]

Hmm, I think that's implementation dependent.  For
example, the Oracle CachedRowSet implementation
doesn't support updating joined tables.  See:

http://otn.oracle.com/docs/products/ias/doc_library/90200doc_otn/web.902/a90211/rowset.htm#628357

I don't know for sure, but I'll wager the RI doesn't,
either...

setting debug level for digester, sax, beanUtils...

Hi,

I am trying to turn off logging for Struts and sub-components while keeping
logging on for my own code. I have put the debug and detail init parameter
to 0 in web.xml but I receive debug messages from digester, sax, beanUtils
and others.

Does anyone know how to confugure the struts-config or/and web.xml?

ApplicationResources.properties not reloading added keys

Hi:

I am using jboss-3.03 with tomcat 4.05 and I cannot get my
ApplicationResources.properties to display newly added keys. I have
restarted jboss and still no luck. All I get is a message like this:
???en_US.prompt.application.url???
I know that the file ApplicationResources.properties  is under
WEB-INF/classes and it does have the prompt.application.url key.

If anyone has any idea how to solve this under the environment described

Eric,
I'm facing the same problem. I just started a week ago and found a few

my first Strtuts application

Check out the following urls

It's part one of a 3 part piece and there are 2 more about struts 1.1

Have fun

Is there a way to turn this off?  Or a reason it's happening?  I don't want
to persist sessions, I'd rather they die and go away if there's any problems
on the server.  

I'm running tomcat 4.1.12 in dev and 4.0.4 in production and just today I've
started seeing it in both places for the first time.  I'm running struts
1.1-b2.

RE: [OT] Safari

[Paananen, Tero]

My company did the 30-day (or whatever) trial subscription
thingie and I was one of the people selected to evaluate
the service.

The selection of books was excellent, but the user interface
and the tools provided for you were somewhat...um...unpolished.
This was 6 months ago. They may have improved since then.

I, personally, found that the service is more valuable when
you're learning something new instead of when you're using
it as a reference. Since 90% of my time reading technical
books is for reference, I felt the service had not that much
to offer me. YMMV.

The service is expensive (for corporate accounts). We decided
that it was too expensive for the benefit and did not continue
our subscription after the trial period.

Convince your company do get the trial subscription and you
can try the service yourself. It costs nothing.

Re: [OT] Updating CachedRowSet

[V. Cekvenich]

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/basicportal/basicportal_07/src/basicWebLib/org/commons/DAO/BasicDAOImpl.java

Above has a working DAO implementation that uses RowSet.
The idea is that you can have many implementations using DAO.
(So, next to it is same DAO that uses SQL-Commons. I only use light 
weight DAO becuase they have higher performance and mostly zero copy beans).

After you review above, follow up.

Why are you setting the writer to null?  It's the

Re: perform() or execute()?

[Jim Bruno Goldberg]

I try it again, from the beginning and now this works. I don know what
I do before but I am happy now. Thanks for David and Patrice to help me.
Now I have a new (and diferent) problem. I construct the follow
validate() in a ActionForm class:


CODE BEGIN---

public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request) {

ActionErrors errors = new ActionErrors();

if ((username == null) || (username.length() < 1))
errors.add("username", new ActionError("errors.nousername"));

if ((password == null) || (username.length() < 1))
errors.add("password", new
ActionError("errors.nopassword"));

if ( !password.equals(again))
errors.add("passwordagain",new
ActionError("errors.passwordnotmatch"));

return errors;
}

CODE END

...and I have the follow entrys on my message resource file:

FILE BEGIN
(application.properties)--

# -- standard errors --
errors.nousername=O campo username deve ser preenchido
errors.nopassword=O campo senha deve ser preenchido
errors.passwordnotmatch=As senhas digitadas devem ser iguais
errors.header=

errors.footer=
# -- validator --
errors.invalid={0} is invalid.
errors.maxlength={0} can not be greater than {1} characters.
errors.minlength={0} can not be less than {1} characters.

 The behavior on form looks like OK, but the messages (inside the

Please, can someone help to me again? Thanks a lot.

Re: J2EE-compliant class loading

[Johan Eltes]

This is going slightly OT :-)
Maybe I should switch to J2EE-INTEREST...

And I was responding to your statement on having multiple versions of the
same library in the same ear (i.e. In different modules of an ear). I would
say that the J2EE spec clearly advices component providers not to rely upon
this to work in all J2EE app servers. From your comments, this restriction
seem to be un-necessary for web modules.

Bottom line is that the class loader problem is fixed in struts 1.1. It
seems to be a general policy of the different apache projects (noticed that
log4j has also switched to using the thread context class loader for loading
resources).

We'll live with the patched 1.0.2 until 1.1. is released.

You can indeed configure auto-reload -- you specify how many seconds in
between checks (Tomcat runs a background thread to actually perform them).
However, that's not my favorite approach when developing a webapp.

Instead, I set up the Ant build.xml file for my webapp to use the custom
Ant tasks that are shipped with Tomcat 4.1 (documented on the
manager-howto page).  I create targets for "install" and "reload" that are
dependent on the "compile" target, and an "unload" target for when I'm
done.

Now I fire up Tomcat (if not already running like it usually is), and my
development cycle goes like this:
 (0) ant install
 (1) test the app
 (2) modify something
 (3) ant reload
 (4) still testing ? goto (1) : goto (5)
 (5) ant remove

I find it much more effective to reload on command, rather than wait some
arbitrary number of seconds at step (3) for the container to notice that
something changed.  Note that this works whether or not you actually
configure the webapp as reloadable or not.

The top-level build.xml file in the Struts distribution has targets like
this for each of the webapps included with Struts (i.e.
"install.documentation", "install.example", and so on) that you can use
for examples.  For this to work, you need to copy the catalina-ant.jar
file (included in Tomcat's server/lib directory) to your $ANT_HOME/lib
directory.

Re: [OT] Updating CachedRowSet

[David Graham]

Sorry I don't know how to fix your problem but I do have some comments.  It 
looks like your DAO class has a bunch of static methods.  It's better to 
have your DAOs be singletons and be created with a DaoFactory.  This allows 
various DAO implementations to be plugged in later.  You lose this benefit 
when using static methods.

Date: Tue, 26 Nov 2002 13:46:19 -0600

I'm stumped.

In my DAO I return a disconnected CachedRowSet object back to my business
logic level, do some processing, then update the CachedRowSet so I can send
it back to my DAO and update my database.  The code basically looks like
this:

	
		CachedRowSet crs = new CachedRowSet();
		try {
			crs = DAO.findUserProfile(user);

			 do stuff 

			crs.updateString("userInfo", userInfo);
			crs.updateRow();
			crs.setWriter(null);	/* kill the default writer
*/
			crs.acceptChanges();
			DAO.updateUserProfile(crs);
		}
	

I can print out the updated userInfo and see that it has been changed.  But
when I print out the contents of the 'userInfo' column from the
CachedRowSet, it still has the original values.  I think it has something 
to
do with not being on the correct row, but all of the doc I can find leads 
me
to believe that the code above should work.  Does anyone have any ideas why
this doesn't?

When you forward to another action the ActionServlet will look up the
action mapping and automagically instantiate and populate the ActionForm
for you... you don't need to do anything except manage the mapping in

RE: Tomcat Freezes when an Action or ActionForm is updated

Craig happened to point this out that Tomcat will reload automatically
now:

At the same time as 1.1 was being developed, work progressed on things
like Tomcat's reload command via the Manager webapp (so you can have
reload-on-demand, scriptable with an Ant task in 4.1, running pretty
quickly, complete with saving and restoring your session), it really
doesn't make sense for Struts to half-implement a feature that
containers fully implement already.

I solve this kind of problem with session scope beans. The CustomerView

I'm not using .  The tabbed tiles code generated the URLs from
this in tiles-defs.xml:

  



  
  

  

And the first tab displays *perfectly* but you can't click on the tabs.

Do I need an Action for the tab body that merely forwards to the appropriate
page?  Something like:
   

But then I have to keep the setup in two places, in tiles-defs.xml and also
in struts-config.xml for the Action. :(

Obviously my  is wrong, because whatever is there is what is
used for the links on the tabs.  I was thinking of Actions always in
conjunction with ActionForms, but I think in this case there will be an

RE: [tiles] More tiles questions

[James Mitchell]

You probably already know this, but:

1. You cannot redirect if the jsp are under /WEB-INF, you ONLY forward
2. You must always go through an action (do not link from one jsp to another)
3. Make sure when you link or post to an action, that you do so with '/' as the
   first character for your action, if you don't, then you could potentially
   get: 1) a 'growing' URL
 or
2) incorrect path to your *.do


 can screw you up

Consider this ( #1 ):
(Not using )

Display

So you click on it and you see this in the address bar:

 http://www.mydomain.com/items/displayItem.do?foo=bar

ok, now if that same link is on the page, click it again:

  http://www.mydomain.com/items/items/displayItem.do?foo=bar
  ^

see what happens?




( #2 )
Now if you had used  then your link would do this:
 (assuming jsp is at /WEB-INF/jsp/)

 http://www.mydomain.com/WEB-INF/jsp/items/displayItem.do?foo=bar



Since you are using jsp under /WEB-INF, I would not use  unless
you are sure that all client side references (images, css, js, etc) are
using to the correct url.

Hope that helps you.

Action mappings

[Mark Minnie]

Maybe I am missing something, but.

I have a customer form (CustomerView.do) that takes a HTTP GET parameter to
show a customer.  (ie. CustomerView.do?customerid=4).  On this customer
form, there are links to JSP pages to modify the data of the customer.  If I
wanted to add a phone number, then I would call addcustomerphonenumber.jsp.
The AddCustomerPhoneNumber.do action mapping is as follows:

 
  
  
  
 

This action populates the customer form (puts a hidden input field
containing the customer number "4") and the addcustomerphonenumber.jsp is
displayed. When the user SUBMITS the addcustomerphonenumber.jsp the
SaveAddedCustomerPhoneNumber action is called.


  
  
  


MY PROBLEM IS:
This saves the customer phone number, but I get an error that the customer
bean is not found in the scope null.  This is because the "success" forward
is forwarding to /CustomerView.do with NO GET PARAMETER.  Since this get
parameter is dynamic depending upon the customer, how do I return to the
CustomerView.do?customerid=4 

Struts is designed to have the action mappings make the MVC design be
easier.  Do I manually have to put code into
SaveAddedCustomerPhoneNumber.java to have the servlet forward the request
back to the HTTP referrer?  I would be surprised is STRUTS does not have a c
lean method to handle something like this.

Thanks for any help in advance.

I was responding to your concern that J2EE apps could not make the
assumption that there was a separate class loader per web application,
when in fact there must be one in all J2EE-compliant app servers (as well
as any stand-alone servlet container that is tested against the servlet
TCK tests).

For EJBs and other J2EE components, there are definitely fewer assumptions
you can make.  But webapps wouldn't work at all according to the servlet
spec if they were loaded from a single class loader.

[tiles] More tiles questions

[Wendy Smoak]

Finally!  I have a tabbed tiles page working.  Sort of... 

I go to http://host/dev/testAction.do and I see that URL with my brand new
tabbed page with the first tab selected.  Then I click the second tab, and
it tries to go to this URL:

http://host/dev/WEB-INF/jsp/tilesTest/tabsTest.jsp?selected=1

The 'jsp under WEB-INF' thing is popping up again!  I'm stuck.  

I think the tabbed links should go back to the Action.  In my case, I want
to do a "Person Profile" with tabs.  It will come up with name and address
on the first tab.  When the user clicks, say, the "Employment History" tab,
I will need to talk to the database and put some beans in scope to be
displayed.

(In addition, I need to do some verification because not all of the users
will be allowed to see data on all of the tabs.  But I'd be happy at present
if *I* could just see all of them. :)

I'm not quite sure where I've gone wrong, so I would appreciate any hints or
advice you can offer.

Re: J2EE-compliant class loading

[Johan Eltes]

My understanding of the J2EE spec is that it may add restrictions / 
requirements on top of the bundled specification. An application server 
(including its containers) must implement restrictions imposed by the 
J2EE spec to be compliant. It is not necessarily enough to fully 
implement all bundled specs.

There are several examples of restrictions following this pattern. JDBC 
2.0 is another bundles specification of J2EE 1.3. The JDBC spec does 
not mandate support for batch update. The J2EE specification requires 
(J2EE compliant) JDBC drivers to support batch update.

The  method has been deprecated since struts 1.1: so it can't work in struts
1.0.2

To populate a form from an action, you need to cast the ActionForm passed as
parameter to the perform (or execute) method of your action and then, set
the different properties to the appropriate values:
for example:

MyForm myForm = (MyForm) form;
myForm.setMyField("myValue");

> 3. To prepopulate a Form, I must to call a Action, prepopulate a bean

I don't know what you mean with "call a Form".
You just need to set the properties of the form with the values you want
Then, the taglib will display the values in the field of the form, on your
JSP.

RE: Tiles and parameters...

[Van Riper, Mike]

Unless I'm missing something here, you simply use:

  request.getParameter("fieldid");

in scriptlet code in any of your leaf JSPs to access this request parameter.
You can also use   in conjunction with this to define a bean at
the top of your page for use as a bean reference in other Struts tags within
your JSP pages. You must be new to JSP development. I recommend taking a
look at the JSP spec. In particular, section 2.8 of the JSP 1.1 spec lists
the implicit objects available to all JSP pages.

Good Luck,

Managing a workflow with Struts-workflow.

[ROSSEL Olivier]

I want to have a workflow which is

MainPage.do -> FirstStep.do -> SecondStep.do -> ThirdStep.do -> Result.do ->
MainPage.do
  (1.jsp) (2.jsp)
(3.jsp)

where each step is supposed to fill one part of a big ActionForm.

I think each Step will test if the part of the ActionForm
it handles is already filled (then the current step must be skipped), 
and if so, it forwards to the next action.

Is it the good way to do the job?

I am not sure to see the benefit of using the workflow plug-in.
I declare the workflow in my struts-config.xml, but still have to hard 
code next/previous URLs in my JSPs.

The benefit is of course that the workflow detects if the user
broke the natural chaning by clicking several "Back" in his browser.
But if he did, he could have some reasons, and this may not be an error.

Well, I am sure I misunderstand something, but any help is welcome.

You might want to review section 9 of the Servlet Spec, which (among other

web application.

Controller class in tiles

[Alvarado, Juan (c)]

My definition looks as follows:






my controller class extends TilesAction and implements Controller. The
execute method is below:

public ActionForward execute( ComponentContext context,
 ActionMapping mapping,
 ActionForm form,
 HttpServletRequest request,
 HttpServletResponse response)
  throws IOException, ServletException{

Logger logger = Logger.getLogger(GetApplications.class);
logger.debug("execuite on GetApplications was called...");
context.putAttribute( "TEST", "TEST");
return null;
}

In my JSP I have the following:



The problem I have is that the controller action class is not getting
called. All I want for now is to be able to print the value of TEST to make
sure everything is working.

Can someone tell me if I've missed anything in my configuration. I've looked
at the samples, but I can't figure out how exactly you get your controller
to get called.

Thanks in advance

RE: Struts-el strange behav.

[Beeson, Ashley]

No you don't because they are form elements then the form to which they are
associated is inferred by the action path.

An element will attempt to populate itself with the get method of the form.
Make sure that you either declare the variable and give it a starting value
(even if it just blank - anything but null) or have your getter return a
non-null default value if the variable is currently null.

I *think* that if you provide the "value" then the getter method is not
called.  So I don't think you've solved your problem, just masked it.  I
assume there's JavaScript somewhere that's going to set a value for that
field before the form is submitted.

What does the 'set' method for selectedCode look like?  I've seen strange
issues crop up when the get/set methods do not match exactly (different data
type, for example.)  I haven't seen it in an official document, but someone
here (Craig??) said that your Forms must conform to the Bean spec.

RE: Include an Action in a page

[shirishchandra . sakhare]

I have not tried this but think this should work..

1: In Action 1, after getting the data,U say return 
maping.findForward("success");
2: success forward does a forward to u jsp1...

In jsp1,U first display data given by action1.
3: thenm after that u do a jsp:inlude which calls action 2.
4:action 2 gets the data and does a forward to jsp2 which shows data from 
action 2. and then does a jsp:include which calls action 3.
5:action 3 then gets the data and does a forward to jsp3 which displaya the 
data from action 3
So in effect u are doing something like
(Jsp1..includes jsp2 and jsp3.)

And if u want to use those actions in other context as well, then before doing 
those fiorwards, u will have to put a check to see where the request is coming 
from(you can use mapping.getParameter()).if its from some other page , then do 
the normal forward which may to another jsp without any includes..

Hope this helps,
Shirish

RE: Problem with struts-workflow distribution (0.9.2)

It works fine.
You should probably append those Struts1.1 instructions
at the end of the INSTALL.TXT.

I have no easy web access, only the archive.
It was quite annoying. I was almost ready to 
think Workflow was a vaporware :-))

Re: Problem with struts-workflow distribution (0.9.2)

[Matthias Bauer]

Olivier,

I guess you mean you are trying to build a war of the struts-workflow 
test application. Please refer to 
http://www.livinglogic.de/Struts/struts1_1.html for instruction how to 
modify the test application in order to get it working with struts 1.1.

According to the stack trace, it looks to me like you have not done the 
first modification mentioned there: Adding "className" to each action in 
struts-config.xml.

When you have done this and still experience problems, let me please know.

--- Matthias


PS: I cc'ed to the struts user list, because these conversations might 
be relevant to other worklow users, too.

I miss (at least) common-logging, common-beanutils and common-collections.

If I add them manually, it does not complain about missing classes.
But it tells me:

you can just use the "titleKey" attribute of "html:link", like this:
