Re: IE ajax theme form data problem
Try turning off the loading text.
It's a guess, but it sounds similar to the loadingText bug due to Dojo
in IE. If the target div contains the source form and loadingText
enabled, the loadingText overwrites the form before the its new values
are read. Details are mentioned several times in this mailing list.

Under IE (6 7), when I modify the data in the form fields and submit

being sent to the server. Has anyone seen this before?

Then s:iterator value=#attr.myListAttribute will definitely iterate

Within your sample code you referenced #item but that doesn't exist.

Re: Tabbed panel performance
Hi Pablo, Consider creating a custom profile for dojo. This makes a significant improvement to the page load time as it reduces the number of http requests (read on first though) http://cwiki.apache.org/S2WIKI/creating-a-custom-dojo-profile-for-struts-20x.html The reload problem you're encountering is that you're either accumulating too many objects in memory or too many nodes in the DOM. Use Firebug to make sure the previous versions of the tabs are not still in the DOM somewhere. Next, you'll have to ensure the widgets objects Dojo created are released from memory before creating them again after the reload (I've never done this...not sure how to ask dojo to dispose of them), and finally you'll have to ensure any listeners attached to DOM nodes inside your tabs are released (this causes major memory leaks in IE if they're not). All of this has to be controlled using the Dojo API, not the struts 2 tags. The dojo struts2 tags in 2.1 include an attribute to control whether dojo should parse the content for widgets. This makes a significant performance improvement rendering tabs that contain a lot of markup. This feature is available in Struts 2.0 version of dojo, but not as an attribute of the Struts2 tag. Again, you'll have to dig into the Dojo/widget API to enable the feature. When I reached that point of complexity (and slowness) I stopped using Dojo and switched to another library. When you're using the Dojo API the benefit of the struts2 tags is completely lost. Most people love JQuery. I use YUI. Dojo1.x looks good too, but I was too burnt to try it. Migrating from the struts2 tags may be a significant effort if you have a lot of notifiers in there, but JQuery and YUI are such a pleasure to use compared to the Struts2 tags so I think you'll find conversion a positive experience without regret. Good luck! regards, Jeromy Evans Pablo Vázquez Blázquez wrote: Just a bit more information.

There's several ways to do this in struts 2. The best approach depends
on what else your application does.
Option 1. Low effort
Implement a custom ActionMapper. It'll contain the logic to detect
that the URI references a user and select the appropriate action with
the username as a param.
Option 2: Higher effort, but generic
a. Use Struts 2.1
b. enable the NamedVariablePatternMatcher (instead of with
WildcardPatternMatcher)
c. Implement a custom ActionMapper that supports IndexActions. (or an
action to invoke when no action is named)
d. Create an IndexAction with namespace /{username}. It'll be
invoked with the username as a param.

This approach is okay. You will struggle with collections though (like
populating the values of a select)
An edge case is radio buttons as they include a hidden field (or was
that checkboxes). Just check the templates for what they render as html.
It is currently working; but can I rely on it?
Do you know how the field- and action-errors can be accessed with
JSTL-EL?
${actionErrors} is a CollectionString
${actionMessages} is a CollectionString
${fieldErrors} is a MapString, ListString where the key is the name
of the field
The reason I do this is because I don't like the struts-tags and OGNL.
That's understandable, but the template system of the tags is quite good
and it may be more productive to create better templates.

FreeMarker is overwhelming at first because the numerous #rt tags distracting from the important fields. I threw together this tool (http://www.freemarker-tool.com/) specifically for tweaking struts2 tag templates (see the examples). In one of my projects, prior to struts 2.0.9, I created a lot of JSP tags (.tag files) that wrapped struts2 simple tags with more behaviour/markup. eg. textfields that included a radio button to enable it first and an attribute to set the radio value. In 2.0.9 EL in struts2 tags was disallowed so eventually I had to rewrite them as custom struts 2 tags.

Re: Struts2 + Dojo 0.4 + unbeforeunload problem
I don't really know as i don't use dojo or the ajax tags for any more
for all the same reasons you're experiencing.
Dojo's event model is based on AOP concepts; which allows you to bind
functions to the event, before the event or after the event.
So you need a listener attached to before the unload event and tell it
to not proceed with the default operation...somehow...
If this was native javascript you'd simply call event.preventDefault()
Related example:
ie. So, if you were doing a confirm for a submit, the submit button
would publish a topic (/submit)
You attach a listener to the before /submit topic
It prompts Are you sure?
If they say no, you cancel the event by setting the event.cancel flag.
In the case of a beforeunload event caught via dojo...not sure. But if
you can get the listener invoked by dojo, then either the scope (this)
or the argument (event) will reference an event object that probably has
the cancel flag.
Otherwise you could try a e.preventDefault using plain old javascript if
you have a reference to the native event object.
The recipes below are for Dojo 0.4.x; so even though they use 2.1.x
tags, the javascript itself also works in Struts 2.0.x; you just have to
write the javascript yourself thats included by within the new tag widgets.

Also, if the script is inline within your ajax response, see the

This is best, as its an iterator, for a for loop:
s:iterator value=valueables

The complication is that the iterator places a new object on the top of
the stage: the object returned by iterator.next, so it's first trying to
get valueables[i] from valueables[i], which is a waste of effort.
Anyway, using your syntax, these should work
s:iterator value=valueables status=status
s:textfield name=valueables[#status.index].description/
s:property value=valueables[#status.index].description/
/s:iterator
But I haven't check as its not the approach I'd use.

Hi Bobby,
Musachy provided the link to the issue in the S2 issue tracker (WW-2653)
which includes a comment that was committed to xwork in revision 1874 on
9 June 08.
Which means if you work from a snapshot version of xwork it's fixed
(which is a 2.1 stream though, which you don't want).
For 2.0.x, you could check out the latest 2.0.x tag yourself, apply the
same minor change, build it into a jar and it'll be fixed for you. Then
you could contribute back the patch for everyone else. That's how we
all got involved in Struts2 and Xwork ourselves.
So you could have this all complete and closed yourself within an hour
instead of waiting around for someone to volunteer to do it for you...

It is probably in Xwork, but Struts2 is so tightly coupled to Xwork it's
much the same thing. Most S2 developers can change Xwork code.
Looks like you received from good help in the jboss forum.
Now that you know where the error occurs, place a breakpoint inside
parseValidators to find out *exactly* which URI is causing the problem.
IteratorURL urls = ClassLoaderUtil.getResources(, ValidatorFactory.class,
false);
while (urls.hasNext()) {
URL u = urls.next();
File f = new File(u.toURI());
It's strange that getResources() is returning a non-file url. What URL
is it returning that causes the exception to be thrown?

A really nice solution so far has been to an action tag to populate

id=groupAction/
...
s:select label=Group name=user.group.id value=%{user.group.id}
list=%{#groupAction.list} listKey=id listValue=name/
That's a novel approach. I like it.
Using %{#groupAcation.list} to populate the drop down works great, but
the only work around I've seen to fill the select box after validation
returns to the form is rather messy:
http://struts.apache.org/2.1.2/docs/how-do-we-repopulate-controls-when-v
alidation-fails.html
I don't see why the above approach wouldn't be working after a
validation failure. When the INPUT result is returned it presumably
renders the same JSP (and doesn't do a redirect). The problem occurs
when the context/valuestack doesn't contain something you're expecting
(such as the list for the select).
Can you confirm whether crud.Group.listAll is invoked after a
validation failure?
Knowing ajax validation will only work with xhtml/css_html theme is
helpful, I've been using ajax all along which may explain some issues.
That should read client-side validation.
You said to use the default interceptor stack for 2.1.2, and the
documentation I read says to use 'jsonValidationWorkflowStack' do I need
both of them or will just the default stack work?
jsonValidationWorkflowStack is correct one.
The autocompleter works because it performs a separate request to
populate the permitted values. Your case is just that the list for the
selects is empty or null.

Re: ajax validation issue
Gawain Hammond wrote: ... That's a lot of problems, and to work-around each problem you've moved to a more sophisticated and complicated solution hoping for the best. You'll need to get the plain-old-validation working first. If validation fails, your action's execute method is not invoked, so you need to ensure all the data needed by the page is available in that case. eg. If you have a select that needs a list of values, then populate the list in the prepare method rather than the execute method. Client-side validation is then generated from your server-side validation settings. It'll only works with xhtml or css_xhtml theme'd forms with validate=true. If it fails in individual tags it's possible there's something wrong with the markup. When you isolate it to certain fields your browser can help you work this out. If you want to use ajax validation you'll need to ensure you're using the default interceptor stack for 2.1.2. It'll use your server-side validation settings. You'll need the sx:head tag in your page and need to be attentive to where you use ajax theme'd tags verses other themes (eg. if you don't want the form posted via ajax). I suggest you go back to basics; create a new minimal form with a minimal action and it get it to work.

Re: REST plug-in Tiles

Moreover, we use conventions to tag CSS to tile definitions. Can you elaborate please? Maybe I misinterpreted your intent. Codebehind/Convnetion is responsible for selecting a result. it'll first check if there's an explicit result (@Result); then search for a JSP matching the convention (eg. order-show.jsp or whatever); then search for a FTL and or VM file matching the convention. The Tiles plugin could augment this process, so if none of the above are matched: search for a Tile with a name matching (prefix.order.show, or whatever). So it wouldn't replace Tiles; it would just allow for the selection of Tiles based on a similar convention. Similarly, the UnknownHandler could attempt match a Tile if no action, jsp, ftl or vm file is found. I never looked further into it than that, but I expect the Tiles plugin could detect the presence of a convention plugin and augment its behaviour. We're not supposed to introduce dependencies between plugins though. None of this affects using tiles within pages. I've just been phasing out the use of TilesResult to use result-by-convention selection so I didn't have to write the above code.

I think that would be generally useful whether used with REST or not. However the main reason I use tiles results is because they're easy to override (eg. by theme and or locale).

Could you point me at some code examples on how to set this up. I've a need to
load a different style sheet depending upon either the locale of the user, or
a user selected locale.
If dealing with Locale, I'd take a different approach. Struts2 sets the
locale on the response object, and the i18n interceptor allows it to be
overridden with the request_locale parameter.
So you could:
a. Reference the locale directly
eg.
link type=text/css rel=stylesheet
href=/css/${pageContext.response.locale}/main.css
or b. use the s:text tag to reference a path specified in a resource
bundle for the current locale
eg.
link type=text/css rel=stylesheet href=s:text
value=env.csspath/main.css
or c. Use Tiles and Sitemesh to include a different tile/decoration
based on the locale (as both support this).
eg. tiles:includeDefinition name=page.cssIncludes/
I don't have any non-trivial i18n experience, so there's probably better
ways. It really depends on what else needs to change on the page; if
you're using a lot of s:text then that's a good approach; if you're
using different tiles then that seems a good approach.

Besides, you could use Parameters and Parameter annotations with Regular

@Parameters( { @Parameter(pattern = page/(\\w+), property = page) })
public class TopicsController(){ }
thus,
get http://localhost/namespace/controller/page/1

Sounds interesting. While it makes for a nice URL, some may argue
against including params for a resource like this..
For params before the Controller (in the namespace) you may appreciate
the NamedVariablePatternMatcher.

Correct, it's just for the namespace, so it can't handle URLs like your parameter handling does. I agree your URL looks better. My preference is the following: The first page of the first post http://example.org/namespace/posts/1?page=1 the first page of posts: http://example.org/namespace/posts?page=1 the index of posts: http://example.org/namespace/posts And, although this isn't a good example, using the NamedVariablePatternMatcher: The first page of the first post: http://example.org/namespace/posts/1/page/1 in which case a PageController is being invoked (useful for genuine parent-child relationships between resources).

Re: REST Showcase 2.1.2
stanlick wrote: Also, what is the naming convention for validation xml files using the Code Behind/REST plug-in? I've tried several combinations of naming, but none seem to work. The short answer is: you can't. It doesn't work. Fortunately annotation validation works correctly in 2.1, so the approach I've used is: - the action carries validation annotations on the applicable methods; - the model's use XML validation as they can be used together and it's well suited to ModelDriven. The problem is that the DefaultValidatorFileParser in Xwork that reads the XML file has no way to specify which method it should be applied to. It applies to the entire class. With wildcards in 2.0 you could get around this because the action alias included the method name. It's the same reason using method='update' spefied in struts.xml never worked properly with XML validation. The parameter was ignored by the XML validator. This had always frustrated me. Fortunately somebody fixed the annotation interceptor so it can distinguish between the methods being executed. Unfortunately that fix (validateAnnotatedMethodOnly) is not enabled by the rest plugin by default. Further compounding the problem is that rest plugin has disabled validation for the edit, editNew and other relevant methods. (I'm not sure why...there must have been a reason for that). What I've done is replace the rest default stack with one that includes the validation interceptor with better configuration: interceptor-ref name=validation param name=excludeMethodsinput,back,cancel,browse,index/param param name=validateAnnotatedMethodOnlytrue/param /interceptor-ref interceptor-ref name=restWorkflow param name=excludeMethodsinput,back,cancel,browse,index/param /interceptor-ref I've been tempted to delve in a fix this but so far I've stayed out of xwork. The rest plugin does the right thing setting up the ActionInvocation with the action name and method name; the XML validation config reader just needs to use the method name to select the file (eg. to load OrdersControler-action-method-validation.xml if it exists). But I feel it already searches for far too many combinations, so I've been reluctant to touch it. stanlinck also wrote: Would you share the interceptor stack to fold paramsPrepareParamsStack capabilities into the restDefaultStack? I haven't experimented with this much with the rest plugin as I try to avoid it . It's reasonable logical... The actionMappingParams interceptor is the one responsible for setting the id, so it needs to appear before the prepare interceptor. If you need other params, before prepare, you also need params before prepare. The actionMappingParams and params are then required after prepare again. ie. set the id, load the object, set the id and params It's different because the ActionMapper obtained the id from URI. If you use other variables in the namespace you also need this interceptor before prepare.

Basically in my REST controller I have a create and update method as per the REST guidelines. I need separate validations for each of these which I do via annotating the methods respectively. A problem arises as I need to separate INPUT results in the case of validation failure 0 one for the create and one for the update but of course this is not doable. I posted a similar response to this list a a few minutes ago. Here's a paraphrase for your specific question: The default configuration for the validation interceptor is not suitable for this. The parameter validateAnnotatedMethodOnly needs to be sets to true so the annotations only apply for the specific method instead of the entire class.

Re: Rest Plugin + IndexController and disabling content types
rakeshxp wrote: Hi All, I have 2 questions regarding the struts-rest plugin ( 2.1.3-snapshot) 1) How can I write a controller that will handle the request on / ( i.e http://www.myhost.com )? No, there isn't. If you substitute the CodeBehind plugin for the Convention plugin, then you can (probably) use an IndexConroller for that. I haven't attempted it myself. The Convention plugin is in the sandbox (not released, and not likely to be until 2.2.x) but Musachy made it work with the rest plugin. Otherwise, create a custom ActionMapper that detects that URI. I create a simple one in an application that instead of returning null (action not found), just returned index; if an IndexController exists it will be invoked. I've found the CompoundActionMapper quite useful to split conventions rather than extending the RestActionMapper. 2) As I understand, the rest plugin by default handles XML and JSON extensions too ( http://struts.apache.org/2.x/docs/rest-plugin.html ) . Is there a way to disable these extensions ? ( Other than overriding struts.rest.handlerOverride.EXTENSION and providing a dummy implementation ) Thanks! You can probably change the struts.action.extension property back so one that excludes xml and json. Otherwise I don't think there's a way to disable an existing ContentTypeHandler other than the way you suggest.

Also, have you considered the likliehood of a user discovering parms that can be passed and mapped onto your action? I am getting push back from folks in security about how Struts 1.X could block this behavior by including only acceptable parmaters in the ActionForm Peace, Scott Hi Scott, I'm not a REST expert, or a REST purist. I like the approach because it makes most things simpler (purists have made it seem complicated and elitist, which is stupid). Generally, I think simpler is good for security administration. If every resource (or service) has a unique URI, then filters (like Acegi) can easily control access to that resource. As soon as params are used to control behaviour it gets complicated. eg. /user/add is easier to filter than userManager.do?action=add Also by following the restful convention for http methods (gets for reads, others for modifications) you can also filter who can invoke the read, update or deletes. Role-based filters can be applied to the request (eg. only admin can post) and to action method's (only admin can invoke create()). It becomes consistent.. None of this solves the discovery of hidden params that can be passed into the action As an example, I suppose if you can create a User and a User has a hidden flag that indicates that they're an admin, and only an admin can set that flag, then there's no good way to filter than other than in the action directly or via the DI framework/java security. eg. you could prevent that method from being invoked by Subjects that don't have the admin role if the DI container allows that or a security manager is setup. I'm not an expert on Acegi either! So yeah, it may help a little because you use keep things simple and follow a convention. You don't need the REST plugin to do any of this though.

If you mean a stateless authentication approach (ie. they sign in once, then each subsequent request includes the credentials so you don't have to maintain a session for them), then: - use HTTP basic (or digest) so the browser must authentic each request - this will need to be setup in your container - if you use a JDBC realm, then, with tomcat at least, you can allow tomcat to access the tables directly and use your own webapp to add/remove users in those tables. To avoid the terrible browser pop-up for credentials: - if the user has javascript, perform login via an asynchronous request; - if the user doesn't have javascript, allow the container to redirect them to a plain old J2EE login page When you have a HTTP server in front of your J2EE container it gets a little more complicated; I'm not too sure about that.

By default, the plugin calls on an AutowritringCapableBeanFactory to instantiate everything requested via the ObjectFactory so you don't require bean definitions for S2 actions, S2 converters or S2 interceptors. I suspect what you're seeing is that: - beans created via the ObjectFactory are using one wiring strategy; but - beans created directly via your application context are using a different wiring strategy. The autowire strategy can be changed via a plugin property.

I dug deeper into this issue and found something very surprising. The
strange behaviour centres around the execute() method. I am very tempted to
call it a severe bug (for Struts 2.1.2)...
To make things simple, I produced a test case (see below): two very simple
ModelDriven Action classes. The first one works as expected, and pushes the
Model (SmallObject) on top of the ValueStack. The second action
surprisingly fails to push the Model on the stack (though the Model is still
accessible through the Action being on the stack).
In short, it seems that the model is not pushed on the stack when its value
is last assigned inside the execute() method!!!
Am I forgetting something, or is this truly a bug?
It might be worth knowing from others if the same problem occurs with
version of Struts earlier than 2.1.2.

I'd also go so far as to so that by learning a request oriented framework rather than a component-oriented one they will have a better understanding of the fundamentals. I have met many ASP.net developers that have no idea whatsoever what a postback is and can't differentiate between client-side and server-side handling which is a concern to me but fine for people that need to output a quick short-lived website. Your training program should try to introduce them to all methodologies and the benefits of each; it's all good and all positive. Prepare your program for the possibility that technology trends change; make that a core strength of your program (developing their skills to be good programmers and adapt to the changes). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: S2: Unable to undeploy app in Tomcat
Hi Paul,
I'm not 100% sure as I've never investigated this in detail myself. Now
that you've mentioned it though, I recall another issue with Struts 2
leaving files open. It related to the FreeMarker template caching and
someone had setup a task to monitor open file counts at run-time.
That would also cause the problem you're seeing and there's probably an
issue in JIRA about that one too.
I rarely attempt to undeploy myself as the application servers run out
of PermGen space eventually anyway requiring a restart. I prefer a
reliable slow restart rather than a fast redeployment with an occasional
failure.
Paul Benedict wrote:
Jeromy,
I wrapped a try/finally in the init and destroy method as you and the
ticket described, but there was still a memory leak that locked down
the Struts 2 core library. Are you sure these are the only things to
be done?
@Override
public void init(FilterConfig filterConfig) throws ServletException {
try {
super.init(filterConfig);
} finally {
ActionContext.setContext(null);
}
}
@Override
public void destroy() {
try {
super.destroy();
} finally {
ActionContext.setContext(null);

Re: [S2] Struts and blob image from Oracle
Your configuration is okay but you have misused the action tag. You
can't embed an inline image within an HTML page.
ie. you've started sending a result, which is from JSP, and then
part-way though you've attempted to output some binary data in the same
output stream.
You do not need special tags. As Gabriel suggested, you simple need an
image tag.
default.jsp:
pThe image follows/p
img src=pgetpicture.action alt=generated image/
That means there's first an HTML stream (from the JSP), then separately
browser opens the image stream from your action.
Hope that makes sense.

Re: [S2] Double conversion issue

Write a custom type-converter for that field to work-around it.

This remove.action is mapped into remove() method in my action class,

What happens now, when user enter, e.g. 1234.0 for prop, it is well
represented here, e.g. prop value is 1234.0 in jsp and my list in action

In effect, the DOM is updated with the loading text before the code reads the values from the form; The result is that the body of the request is empty. Here's the interesting details: http://www.quirksmode.org/js/events_order.html It's the responsibility of the widget to accommodate it, but it's better to use the indicator attribute instead of the loading text anyway.

Re: Authentication way: Should I interceptor s:url or s:a before it render?
Haulyn R. Jason wrote: Hi,all I have an Authentication problem. I use Interceptor to authenticate actions and methods, based on different member and different role. Everything works well.But my client can not access some resource, for example a url, so they should not see the url. I think maybe I can re-write s:a tag or using an Interceptor to check should a s:a /tag be rendered to the clients. I can not find any reference. Without this way, does struts2 have it's own way to solve the problem? Thanks! None of the struts 2 tags are aware of role. In my opinion, it's better to leave that consideration out of these tags as you don't want security checks scattered through all the tag variations. Instead customize the view using tags that render its body only if the user has the specified role(s). Either: - use tags from an existing library (Tiles tags can check role I think); or - create a custom tag that only renders the body if the principal has the specified role(s) eg. security:guard role=admin s:a href=adminpage/ /security:guard Otherwise every tag needs to be modified and that leads to mistakes. *More importantly* secure the server-side first and foremost. Consider customization of the view based on role only as a way to improve the user's experience as it doesn't actually help secure your application. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

In sitemesh.xml, ensure your page-parser is setup only for text/html. You don't want it to attempt to decorate other content types. In decorators.xml, you can probably decorate /*. You shouldn't need any exclusions unless you serve undecorated html as well. You need to isolate whether your css file is being served accidentally decorated, or not served at all.

I think MemberId is null:

Or pageRequested is null
searchForm.setPageRequested(Integer.parseInt(pageRequested));
Or sortByField is null:
searchForm.setSortByField(Integer.parseInt(sortByField));
Just a hunch.
