[ANN] Java Web Parts Beta 5
After a few months off, the Java Web Parts (JWP) team is proud to announce the release of beta 5! The most notable change is that the taglib formerly known as AjaxTags is now known as the AjaxParts Taglib, or APT for short. Not only is the name different, but the taglib has been essentially rewritten and is now easier and yet more powerful than ever... If a declarative approach to AJAX that doesn't require you to know a bit of Javascript (unless you want to get into it) sounds good to you, now is a great time to check out what APT has to offer! There are other additions as well, and as always, JWP provides a number of useful parts, such as servlets, filters, taglibs, utility classes, and so forth. Things like getting the size of a session object, a powerful CoR implementation, filters to limit concurrent sessions, guard against XSS exploits and disallow app access during defined time windows, a class to make application configuration simple, a servlet to dynamically render a text of string as an image, a taglib that renders very handy Javascript functions, some GUI widgets... all of this can be found in JWP, and plenty more! If this sounds interesting to you, have a look: http://javawebparts.sourceforge.net And for you Maven folks, JWP can now be found in the iBiblio repo! (beta4 at this point only though) Thanks, and have a great day! Frank -- Frank W.

EJB 3.0 out-of-the-container support with struts or shale
the ejb 3.0 specifivation is done standard! does anyone get successful support for an struts or shale project using ejb 3.0. glassfish reference implementation works only with vm argument -javaagent - but is this maybe possible to combine with webframeworks ala struts or shale. important is that it is out of the container - only using ejb3.0 implementation libaries and it is possibly from controller side using ejb 3.0 for persistence. is this impossible? it shouldn't, but no solution found, yet. stephan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Struts and Hibernate
Hello, I'm working on struts and hibernate. J'ai une tache qui est affectée à un utilisateur. I have a Actionform named Task. Private Integer code ; Private String codeus ; // Login of user Private String libelle; I have also a POJO Task. Private Integer code; Private User user; // Many-to-one relation with user Class. Private String libelle; And I have a action class which gets back my user's list to show it in a combobox in my jsp when i create a task. Code : html:select property=codeus html:options property=codeus collection=lesUtilisateurs labelProperty=nom /html:select The code above allows me to show a comobox with the names of my users. The parameter sent to get back the user is codeus. Up to there, it works. After recording in my database, my problem is to show the user allocated to the task in modify.jsp. If i do Code : html:select property=codeus name=tache html:options property=codeus collection=lesUtilisateurs labelProperty=nom /html:select my user recording in database is not selected by default. If I do html:select property=utilisateur.codeus name=tache html:options property=codeus collection=lesUtilisateurs labelProperty=nom /html:select My user is selected, but the actionform doesn't recognize my attribute utilisateur.codeus because it wants codeus Does it mean that my actionform must have utilisateur.codeus as attribute ?

Strtus and Portlets
Hi all, I am about to develop a new struts app that will be ported afterwards to be used in a portlet and I plan to use the struts bridge support. I want to try and ensure that I don't break the bridge with my normal conceptual design before I start building anything. The pattern I use is to break up processing of the request from the display of the next page and to handle a form that has multiple submit buttons that need to perform different actions (yes that good old problem) I usually implement this pattern in struts-config to separate out concerns: 1) Page always calls a redirect action that takes the submitaction attribute in the form and finds the forward using the submitaction as the key. 2) The process action then processes the request and on success calls a display action to render the next page 3) The display action finally calls a go action that is the simple redirect to the JSP action path=/logon_redirect name=logonForm type=org.xxx.RelayAction scope=request validate=false forward name=logon path=/process_logon.ask/ forward name=cancel path=/go_welcome.ask/ /action action path=/process_logon name=logonForm type=org.xxx.LogonAction scope=request input=/go_logon.ask validate=true forward name=success path=/display_briefcase.ask/ /action action path=/display_briefcase name=briefcaseForm type=org.xxx.GetBriefcaseAction scope=request validate=false forward name=success path=/go_briefcase.ask/ /action action path=/ go_briefcase.ask forward=/jsp/briefcase.jsp /action This is obviously action chaining and I'm aware that this can cause issues in portlets and the bridge due to the separation of ActionRequests and ActionResponse interfaces. I have read the website and if I'm reading correctly the bridge would separate ActionRequests from ActionResponse processing on the first action forward, in this case on my redirect meaning the process would be part of the render which is not what I want. Am I correct or will the above work OK? What changes may I have to make to ensure I integrate with the bridge seamlessly?

Re: Changing Role Access to Actions on the Fly
I can say with mild confidence that the action mapping is frozen once loaded, and changes to it during runtime cannot be made. Since roles are part of a mapping, it cannot be done. But don't let the framework stop you! Just because its automated configuration features are frozen, doesn't mean you can't get around it. If you are willing to perform explicit role checking inside the action, then you can achieve what you're trying to do. Yes, you will be giving up the XML configuration, but, you're doing something very special; I don't even know if *ANY* framework allows something like this. In my opinion, you might search for a better solution. Perhaps dynamic role changing is a symptom of a bad design.

RE: Changing Role Access to Actions on the Fly
Hi,
Some time ago I was looking for an answer on the same question :)
Here is how I solved this issue.
1) All request goes though SecurityFilter (www.sf.net)
2) Wrapped original request with this one
public class SecurityRequestWrapper extends
org.securityfilter.filter.SecurityRequestWrapper {
public static final char SESSION_ROLE_KEY='@';
public static final String USER_INFO=userInfo;
public SecurityRequestWrapper(HttpServletRequest arg0,
SavedRequest arg1,
SecurityRealmInterface arg2, String arg3) {
super(arg0, arg1, arg2, arg3);
}
public boolean isUserInRole(String roleName) {
if(roleName.charAt(0)==SESSION_ROLE_KEY){
SecurityFilterPrincipal
principal=(SecurityFilterPrincipal)getUserPrincipal();
String
roleKey=(String)getSession().getAttribute(String.valueOf(SESSION_ROLE_KE
Y));
if(principal!=null roleKey!=null){
Map roleMap=principal.getRoleMap();
List roles=(List)roleMap.get(roleKey);
if(roles!=null){
StringTokenizer tokenizer=new
StringTokenizer(roleName.substring(1),,);
while(tokenizer.hasMoreTokens()){
if(roles.contains(tokenizer.nextToken()))
return true;
}
}
}
return false;
}
return super.isUserInRole(roleName);
}
}
and modified doFilter method to use my Request Object
...
doFilter(...){
HttpServletRequest hReq = (HttpServletRequest) request;
HttpServletResponse hRes = (HttpServletResponse) response;
SecurityRequestWrapper wrappedRequest;
... (the rest is coppied from SecurityFilter sources)
}
3) Created Principal interface implementation in SecurityFilterPrincipal
object with map property holding all userRoles
public class SecurityFilterPrincipal implements Principal,Serializable {
private String name=null;
private HashMap roleMap=null; //roleMap[key]=ArrayList(roles)
..
(just create getter and setters for properties)
}
4) Implemented SecurityRealmInterface interface
public class JDBCSecurityFilterRealm implements SecurityRealmInterface {
..
(find the source of this class in SecurityFilter)
.. change the login function to reflect your situation
(here I load all user roles but into my Principal's roleMap property)
}
5) The most important in all of this is implementation of isUserInRole
function (SecurityRequestWrapper object). The way you check your roles
there are up to you. In my case I put into the session some indicator
telling me which key in the rolesMap is the active one. In this way
although I'm not dynamically removing roles I switch them accordingly to
the situation.
Hope it's what you want.

I know this is not the list for this question. However, there are so many

I have the following frameset in my application. I need to collapse expand

else
{

Thank you Paul for your comments, Adding/removing Roles, adding/removing users to roles, then permitting/forbidding various actions for these roles is what I want as the main feature of my App. I have an idea of using filter that would do explicit permissions to roles on actions, based on configurations of role-action mappings from the database.

[STRUTS] Resource bundle and form validation
I use several resource bundle for my application. The particularity is the resource bundle is depending of the user?group. Here, an extract from the struts config file : message-resources parameter=com.convergence.ressources.ressources null=false / message-resources key=angers parameter=com.convergence.ressources.angers.ressources null=false / message-resources key=angersErreurs parameter=com.convergence.ressources.angers.erreurs null=false / message-resources key=nantes parameter=com.convergence.ressources.nantes.ressources null=false / message-resources key=nantesErreurs parameter=com.convergence.ressources.nantes.erreurs null=false / plug-in className=org.apache.struts.validator.ValidatorPlugIn set-property property=pathnames value=/WEB-INF/validator-rules.xml, /WEB-INF/validation.xml / /plug-in When I submit a form to be validated There is no problem to post the right message from the right resource bundle, whether the validation is on the client side (with javascript)or on the server side. But these messages to be posted contain some arguments (the names of the invalidate form fields). That?s the problem. The validation on the customer side returns arguments from the right resource bundle (the same which contains the messages to expose) due to the following tag in the JSP: html:javascript formName=frmSelection bundle=angersErreurs / The validation ont the server side returns arguments from the application resource bundle (the default resource bundle as declared at the struts config file : message-resources parameter=com.convergence.ressources.ressources null=false / However the JSP declaration is : html:errors bundle=angersErreurs/ Because of the dynamic call of the resource bundle(in the jsp examples, i hide the dynamic bundle call for more readability ), it isn't possible to specify the resource bundle on the validation.xml file as field arg0 attribute from the field field. Extract of the file validation.xml : formset form name=frmSelection field property=contexte depends=required arg0 key=frmSelection.contexte / /field field property=selection depends=required arg0 key=frmSelection.selection / /field /form Does exists a solution at this problem of behavior between server and client or is it a bug from struts?

RE: java.lang.IllegalArgumentException: can't parse argument numb er
Fredrik,
The property value of {common.a} is causing the problem b/c the
java.text.MessageFormat class
is used to to parameter replacements in the message. Are you trying to use
the literal string
'{common.a}' as the value of the key? If so, you need to escape the '{' and
'}' characters.

RE: Struts and AJAX
Hey,
I use DWR + dojo to use AJAX with struts:
http://getahead.ltd.uk/dwr/
http://dojotoolkit.com/
Although dojo has some flashy widgets and stuff, its power is the
dojo.io.bind() function:
http://dojotoolkit.org/docs/intro_to_dojo_io.html
Here is an example of using Struts Actions with bind():
html:form styleId=compose_mail_form method=post
action=process_new_mail enctype=multipart/form-data focus=to
label for='to' logic:messagesPresent
property=toclass='error'/logic:messagesPresentTo:/label
html:text property=to styleClass=text style=width: 25%; /
br class=clear /
...
//more form elements
...
a href=# onclick=submitNewMail();SUBMIT/a
/html:form
NOTE: form has been given a 'styleId' and using logic:messagesPresent to
display errors in form
function submitNewMail(){
//validateNewMail(form);
var bindArgs = {
url: html:rewrite action=process_new_mail /,
error: function(type, data, evt){
alert(An error occurred submitting new mail: + data);
},
load: function(type, data, evt){
DWRUtil.setValue(social_mail_right_con, data);/* setValue
doesn't execute javascript! */
document.getElementById('social_popup_layer_container').innerHTML=document.getElementById('ajax_hidden_helper').innerHTML;
popup('social_popup_layer_container',true);
},
mimetype: text/html,
formNode: document.getElementById(compose_mail_form)
};
dojo.io.bind(bindArgs);
}
NOTE:
1) the use of html:rewrite / for the 'url'
2) formNode is the 'styleId' of your html:form /
3) the stuff you see in the load function is application specific. It is how
I display html:errors /
and html:messages / in a backwards-compatible manner for AJAX. I
basically force
the reloading of a JSP (tile) that has the code: html:errors / and
relevant logic.
Ok, now for the good stuff:
1) Yes, your ActionForm will work as usual. If it is invalid, errors are
displayed. If it validates, it goes
on to the Action.
2) The action MUST RETURN NULL, otherwise the page will reload to your
forward
3) You write your output to the response object in your action. Remember
when it was just servlets?
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
IOException, ServletException {
//Make ActionMessages for business logic errors...
ActionMessages messages = new ActionMessages();
HttpSession session = request.getSession();
MyForm f = (MyForm)form;
response.setContentType(text/html);
PrintWriter out = response.getWriter();
out.print(ACTION_SUCCESS:Message Sent!);
out.close();
//return(mapping.findForward(success)); NOT AJAX WAY!
return(null);
}
There are many ways to handle the repsonse stuff with AJAX + STRUTS. Use
your imagination.
In this instance I just have a javascript function parse the output. You
could return HTML and use
innerHTML(). You could parse a string like: FORWARD:my_action_name.
You could have: JAVASCRIPT-FUNCTION:handleSuccess().
I often use dojo.io.bind() in conjunction with DWR.setValue():
http://getahead.ltd.uk/dwr/browser/util/setvalue
or using DWR to forward to a JSP:
http://getahead.ltd.uk/dwr/examples/text
Bottom line is that javascript will handle the forwarding instead of you
struts config.
If some has a way to do it with the config, I'd love to hear from you.
BTW - I took the time to write this because after all the reading and
searching I did,
I still didn't have a clue how to use all this stuff together. I hope this
helps everyone.

Re: Struts and AJAX
I'm a big fan of DWR as well, it's a very worthy alternative.
But, I don't mind a little self-promotion, so... how does this strike
you? ...
ajaxConfig
group ajaxRef=MyForm form=compose_mail_form
element ajaxRef=SubmitButton
requestHandler type=std:QueryString target=/process_new_mail.do
parameterto=to/parameter
responseHandler type=std:Alerter
parameter /
/element
/group
/ajaxConfig
Then, in your JSP:
html:form styleId=compose_mail_form method=post
action=process_new_mail enctype=multipart/form-data focus=to
label for='to' logic:messagesPresent
property=toclass='error'/logic:messagesPresentTo:/label
html:text property=to styleClass=text style=width: 25%; /
br class=clear /
...
//more form elements
...
a href=#SUBMIT/aajax:event ajaxRef=MyForm/SubmitButton /
/html:form
ajax:enable /
This would result in some Action, mapped to process_new_mail.do being
executed, and you would get a single parameter submitted, to, using
the value of the form field to. The response from the server,
whatever it is, would be displayed via alert().
This is what AjaxParts Taglib (APT) offers... you define an event in a
config file, some user-initiated (usually) event that fires an AJAX
request. For each event, you define a request handler, which forms the
request to the server... there are a number of standard handlers, for
instance, if you want to construct XML from your form, that's standard.
You also define one (or more) response handlers, which is something
that happens when the response comes back. Again, there are a number of
standard handlers, like Alerter... there is also things like InnerHTML
(populate a page element by updating innerHTML), stdXSLT (transform XML
response via XSLT on client), and much more.
Note that you didn't have to right ANY Javascript whatsoever! And the
changes to your JSP amounts to adding an ajax:event tag to any element

NOTE:
1) the use of html:rewrite / for the 'url'
2) formNode is the 'styleId' of your html:form /

how I display html:errors /
and html:messages / in a backwards-compatible manner for AJAX. I
basically force
the reloading of a JSP (tile) that has the code: html:errors / and
relevant logic.
Ok, now for the good stuff:
1) Yes, your ActionForm will work as usual. If it is invalid, errors are
displayed. If it validates, it goes
on to the Action.
2) The action MUST RETURN NULL, otherwise the page will reload to your
forward
3) You write

This is what AjaxParts Taglib (APT) offers... you define an event in a
config file, some user-initiated (usually) event that fires an AJAX
request. For each event, you define a request handler, which forms the
request to the server... there are a number of standard handlers, for
instance, if you want to construct XML from your form, that's standard.
You also define one (or more) response handlers, which is something
that happens when the response comes back. Again, there are a number of
standard handlers, like Alerter... there is also things like InnerHTML
(populate a page element by updating innerHTML), stdXSLT (transform XML
response via XSLT on client), and much more.
Note that you didn't have to right ANY Javascript whatsoever! And the
changes to your JSP amounts to adding an ajax:event tag to any element
that will fire an AJAX event, and the ajax:enable tag at the end (plus

Re: [STRUTS] Resource bundle and form validation
Support for different resource bundles in the Commons Validator DTD was added in Struts 1.2.7 and Commons Validator 1.1.4 (although I would recommend Struts 1.2.9 if you're upgrading and Validator 1.3.0). So in you validation.xml you can specify a bundle attribute on either the msg or arg element: field property=contexte depends=required msg name=required key=custom.required bundle=angersErreurs/ arg position=1 key=frmSelection.contexte bundle=angers / /field There is a bundles example page (in the validator section) in the struts-examples.war webapp which is shipped with the binary distribution. You will need to switch from using the arg0 - arg3 elements to the new arg element to take advantage of this. For example arg position=0/ is the same as arg0 and if you don't specify the position attribute then it will guess a (hopefully) sensible value.

But these messages to be posted contain some arguments (the names of the invalidate form fields). That?s the problem. The validation on the customer side returns arguments from the right resource bundle (the same which contains the messages to expose) due to the following tag in the JSP: html:javascript formName=frmSelection bundle=angersErreurs / The validation ont the server side returns arguments from the application resource bundle (the default resource bundle as declared at the struts config file : message-resources parameter=com.convergence.ressources.ressources null=false / However the JSP declaration is : html:errors bundle=angersErreurs/ Because of the dynamic call of the resource bundle(in the jsp examples, i hide the dynamic bundle call for more readability ), it isn't possible to specify the resource bundle on the validation.xml file as field arg0 attribute from the field field.

Re: Struts and AJAX
Good questions! Let me see if I can answer them... draegoon Z wrote: What about errors in the ActionForm? APT doesn't say anything at all about what happens on the server, so, the short answer is its up to you :) The longer answer is that each of the response handlers (as of the latest beta5 release) has a matchPattern parameter, which is a regex... with that, you can examine the response and either fire the handler or skip it. So, for instance, it may be that you want to make an AJAX request when the user clicks a button to do some validations... there are two possible outcomes... one is an OK response, for which you just want to put the returned message into a div let's say... the other outcome is validation errors, in which case you want to pop the response via alert() let's say. So, configure two response handlers: responseHandler type=std:InnerHTML matchPattern=/ok/ parametermyResultDiv/parameter /responseHandler responseHandler type=std:Alerted matchPAttern=/error/ parameter / /responseHandler Now, my regex is a bit rusty, so pay attention more to the theory than the details :) The idea is that the first handler will only fire is ok is found in the response. Likewise, the second one will only fire if error is found. Since you can absolutely use a JSP to render the two responses, you use the same set of Struts skills as you always have to create the response. What about firing javascript function before the submit? I.e., to validate the form (I don't use Validator). As of the latest beta5 release, you can specify both a post-processing and pre-processing function to do exactly that. You can set this on the group, element or event levels. Alternatively, if your really doing something more complex, you can write a custom handler. This amounts to an entry in the config file like so: handler name=MyHandler type=request functionMyJSHandler/function locationlocal/location /handler From then on, you can use MyHandler as the value of the type attribute of a requestHandler element. You can do whatever you want there, and, you STILL won't have to write much code because you can use the built-in RequestSender() function, which takes care of all the AJAX details for you... you just write the business logic, so to speak, and call RequestSender() to take care of all the call details. Does the Action have to return 'null' and write directly to the response, or can the struts config still be used? You can do either. Your response can be rendered via JSP, which we actually recommend 99% of the time, so you can write your struts-config the same as always.

Re: Struts and AJAX
Sounds great so far, but I think I lost you on the first part. Let's work through a simple problem... Let's say I have in my struts-config: action path=/my_action forward=tile.my_action / action path=/success forward=tile.success / action path=/error forward=tile.error / action name=MyForm path=/process_my_action input=/my_action.do scope=request type=com.draegoonZ.action.MyAction forward name=success path=/success.do / forward name=error path=/error.do / /action First, what happens if MyForm just simply returns an ActionError? Second, what if MyAction has ActionErrors and forwards to its 'error' page? Are you saying that APT gets the response (JSP,text,HTML, whatever) and matches the regex to that entire response string? If so, how do you advise setting flags in the response to ensure the proper responseHandler is called without neccessarily displaying the flag itself.

Let me see if I can answer them... draegoon Z wrote: What about errors in the ActionForm? APT doesn't say anything at all about what happens on the server, so, the short answer is its up to you :) The longer answer is that each of the response handlers (as of the latest beta5 release) has a matchPattern parameter, which is a regex... with that, you can examine the response and either fire the handler or skip it. So, for instance, it may be that you want to make an AJAX request when the user clicks a button to do some validations... there are two possible outcomes... one is an OK response, for which you just want to put the returned message into a div let's say... the other outcome is validation errors, in which case you want to pop the response via alert() let's say. So, configure two response handlers: responseHandler type=std:InnerHTML matchPattern=/ok/ parametermyResultDiv/parameter /responseHandler responseHandler type=std:Alerted matchPAttern=/error/ parameter / /responseHandler Now, my regex is a bit rusty, so pay attention more to the theory than the details :) The idea is that the first handler will only fire is ok is found in the response. Likewise, the second one will only fire if error is found. Since you can absolutely use a JSP to render the two responses, you use the same set of Struts skills as you always have to create the response. What about firing javascript function before the submit? I.e., to validate the form (I don't use Validator). As of the latest beta5 release, you can specify both a post-processing and pre-processing function to do exactly that. You can set this on the group, element or event levels. Alternatively, if your really doing something more complex, you can write a custom handler. This amounts to an entry in the config file like so: handler name=MyHandler type=request functionMyJSHandler/function locationlocal/location /handler From then on, you can use MyHandler as the value of the type attribute of a requestHandler element.

So, if I need to print out error messages, I just need to mark html:errors/ tag with ajax:enable / ? No, that isn't quite right... What APT does is attaches AJAX events to an element on a page (it can theoretically be any DOM element). This attached event fires in response to one of the usual event handlers, i.e., onClick, onBlur, whatever (you can also have an AJAX event that fires continuously via timer, and you can also have a function rendered that you can call at will to fire an AJAX event which is still configured like any other). So, when working with Struts, your Action (or more usually, a JSP) can really render whatever it wants... APT has nothing to say about that (at this point... some plans in the works). Most of the time is would probably NOT be a full page... then, back on the client, APT kicks in again via a response handler, and does something with the response. That something can be updating a div, populating a select, doing an XSLT transformation, popping an alert, or a number of other things (and that's the just standard handlers... with a custom handlers, the possibilities are limited only by your imagination). Now, one new capability that a lot of people were asking for is the ability to use APT tags in a response rendered by a JSP that is itself called as the result of an AJAX call... imagine a button on a page that, when clicked, adds a new item entry line to a list. This new line will contain two text fields, one of which you want to fire an AJAX event onBlur for. Previously, you had to do some somewhat annoying things to make that happen, now it's perfectly natural: just use the tags in a JSP that renders the markup for that new item line. Specifically on your question of rendering html:errors/, you would first need to decide how you want to display the errors... in a popup? In a div? Something else? Whatever the case, you create a JSP that contains that html:errors/ tag, and that might in fact be the ONLY thing in that JSP. Then, you configure a response handler to display it however you want. Nothing more to it. What if I print errors separately for every input field, will this still work? Yes, it can, it all depends on what events fire the AJAX call, and what you do with the response. APT is a bit more low-level than some other libraries in that we don't really say much about what you do or how you do it, we just provide tools that we feel makes it really easy to do whatever you want, and saves you from doing Javascript coding yourself (usually, custom handlers excepted). I think grabbing JWP and looking at the sample app is the best way to go... there is a page with probably close to 20 different usages of APT, and I think if you look at that and then glance at the JSP, it'll become clear pretty quickly (there's also a cookbook that might be helpful, although it hasn't been updated for beta5 yet).

Re: Struts and AJAX
Hey Frank,
Check out this code from my first post using dojo.io.bind() :
function submitNewMail(){
//validateNewMail(form); //use javascript validate before form
submit
var bindArgs = {
url: html:rewrite action=process_new_mail /,
error: function(type, data, evt){
alert(An error occurred submitting new mail: + data);
},
load: function(type, data, evt){
DWRUtil.setValue(social_mail_right_con, data);/* setValue
doesn't execute javascript! */
document.getElementById('social_popup_layer_container').innerHTML=document.getElementById('ajax_hidden_helper').innerHTML;
popup('social_popup_layer_container',true);
},
mimetype: text/html,
formNode: document.getElementById(compose_mail_form)
};
dojo.io.bind(bindArgs);
}
I'm sure you're probably familiar with dojo, so forgive me if I'm beating a
dead horse.
What happens here is that my action, /process_new_mail.do, processes like
a normal struts app,i.e., ActionForm.validate() gets called first.
If there are ActionErrors, the input mapping page is returned via the
'data' object.
It is the 'responseText'.
The error: argument:
error: function(type, data, evt){
alert(An error occurred submitting new mail: + data);
}
is NOT called because no Javascript error was thrown.
Instead, the load: function is called:
function(type, data, evt){
DWRUtil.setValue(social_mail_right_con, data);/* setValue
doesn't execute javascript! */
document.getElementById('social_popup_layer_container').innerHTML=document.getElementById('ajax_hidden_helper').innerHTML;
popup('social_popup_layer_container',true);
}
The line:
DWRUtil.setValue(social_mail_right_con, data);
is what displays the response, which is the input page.
Anyways, if there are ActionErrors in the ActionForm and the server
naturally forwards to
the input mapping in the struts-config,
Why doesn't APT get this same response?
Why doesn't it get forwarded to the input page automatically, returning it
in the response?
Does it go through the ActionForm.validate() method in the first place?
If this could happen, you would pretty much have a drop-in solution!
I could be missing something, so feel free to yell at me, but if dojo does
it
I can't see why this shouldn't work for APT also.

Re: Struts and AJAX
I think we were just on two different brainwaves. If APT still goes through the ActionForm.validate() and returns to input page upon ActionErrors, as it should, then APT serves all my purposes with a lot less javascript!

Re: Struts and AJAX
Well that's a bit embarassing, to say the least :( I think I flubbed the build process, although it would have been flubbed days ago, so I'm not sure how it was working during testing. In any case, the TLD isn't in the right place in the JAR, so it isn't being found. Until a new build can be rolled, a quick work-around is to extract the file javawebparts_ajaxparts.tld from the javawebparts-ajaxparts-1.0-beta5.jar JAR and place it in WEB-INF. That should do the trick (did for me). Sorry about that! Frank draegoon Z wrote: I think we were just on two different brainwaves.

It sounds like the time on your computer was accidently advanced. I'd reset your computer time and re-save your pages. A.
