s:div tag and internationalization
Hello,
I'm using s:div tag to load async the results of an action like this:
s:url action=my_action id=myActionUrl/
s:div id=myActionDiv
theme=ajax
href=%{myActionUrl}
loadingText=%{getText('loading')}
executeScripts=true/
my_action has as a result a jsp page in which we use s:text
name=something/. The text is loaded from language resource file but it is
not displayed correctly. We need to display danish words and it works like
this:
in resource file: ... får målt ...
in displayed result: ... f�r m�lt ... (firefox).
If the text is loaded without s:div, it is ok.
Thank you,
Boris.

AW: Re: Implementing ParameterAware but still getting Unexpected Exception caught setting 'name' on 'class....
Hi Laurie, sorry if I expressed not totally clear what I mean - have still some problems with my english! ;) What do you mean that the parameters passed to the action 'change every now and then'? At random?!? If you just mean that there are a variable number of them, no problem; that's what List- and array-backed properties are for. I have some report objects that have different prompts, with those prompts I build a input form and pass them to my ParameterAware action. The parameter names, and also the parameter count changes from report to report. Not sure I understand what you want. Do you just want to suppress the exception report in the logs, or does the exception represent an actual problem you need to fix? If the latter, you'll need to provide more details. I guess you can call it suppress. Its more a cosmetic fix, but I try to understand more of s2 and how to avoid things like that. I have no functional problems with the exception - everything else works like expected! So thanks for your answer, it just would be fine to get rid of it, its not a show stopper, if it can be called like that! ;) Regards Jan Froehlich -Ursprüngliche Nachricht- Von: news [mailto:[EMAIL PROTECTED] Im Auftrag von Laurie Harper Gesendet: Mittwoch, 30.

I have a page with a dynamic number of input fields that is submited to an action that implements ParameterAware. Cause the names of the parameters passed to that action change every now and then I can't write getters and setters for them. Thats what I thought ParameterAware is made for. ParameterAware is just a low-level mechanism for getting access to the raw request parameters. If you want to apply conversion or validation to your request data, or have it injected into your actions or model objects, it's probably not what you need. What do you mean that the parameters passed to the action 'change every now and then'? At random?!? If you just mean that there are a variable number of them, no problem; that's what List- and array-backed properties are for. But even then I get those Unexpected Exception caught setting.. Is there a way to tell s2 that it should stop doing it? Well, ok - not the most clever question, but I just want to get rid of those Exceptions! Not sure I understand what you want.

Re: There is no Action mapped for namespace / and action name ...
Hi, I fixed the problem by reverting back to 2.1.1-SNAPSHOT version with struts core and all the plugins. Changing eclipse to 5.0 is really not a solution for me, so I couldn't do that.

Re: ServletOutputStream
Your action can not generate two responses (if that's what you asking).
If you forward to a 'status completed' page, then you need to save
your excel data somewhere to not loosing it.
2008/7/29 Mike Rooney [EMAIL PROTECTED]:
I created a small webapp that extracts data from a DB, creates an Excel file
from that data (using Apache POI), which then streams the file to the end
user's browser. Everything is working fine, however I have to set the Action
class' return type to 'NULL' since I am setting the servlet response type to
'application/vnd-ms-excel'. I want to change my application so that it
returns to a 'status completed' page when the extraction is completed.
However I cannot do this when I set the return type is null. How can I do
this?
Here is my code...
public class ExtractAction extends ActionSupport {
public String execute() throws Exception {
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet prodSheet = wb.createSheet(PROD);
HSSFSheet devSheet = wb.createSheet(DEV);
HSSFSheet testSheet = wb.createSheet(TEST);

HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType(application/vnd.ms-excel);
ServletOutputStream outstream = response.getOutputStream();
wb.write(outstream);
outstream.flush();
response.flushBuffer();
}
return null;
//return SUCCESS

Hi everyone, I'm using Struts 1.2 (bundled with NetBeans 5.5.1) and I've noticed that I can't iterate through a java.util.Set using the logic:iterate tag. The code that I've tried: logic:iterate collection = skillsFound id= thisSkill scope = session I get this exception: javax.servlet.ServletException: javax.servlet.jsp.JspException: Cannot create iterator for this collection Does anyone know if this is a bug of Struts 1.2 and if there's a later version (not Struts 2) where it's been fixed?

Re: There is no Action mapped for namespace / and action name ...
I know...when I have two projects that use the same package namespace for my app source...I get this Action mapping error. Even when one project is Closed (in the Eclipse sense). I neglected to mention this previously in describing what I changed to make things work. There is still a 'fragility' that has crept into the Struts2.1.3-SNAPSHOT regarding dispatcher filters and actions.

dojo anchor: get widget id and targets attributes inside subscribed topic?
I use dojo anchor widget (s:a/).
It successfully gets response in json from server, but I have several
problems accessing widget, that published a topic.
Please, see my code:
dojo.event.topic.subscribe(/after, function(data, request, widget){
alert('inside a topic event. after request');
//data : text returned from request(the html)
//request: XMLHttpRequest object
//widget: widget that published the topic
});
Problems:
1. Can't change data value. If I use inside dojo.event.topic.subscribe:
data = this my new data!;
alert(This is my new response from server: + data);
alert shows, that data value was changed,
but targets of dojo anchor get previous value (why???).
2.I can't get widget properties: id of widget or targets. That's terrible, I
need them very much. I've dumped the object widget, but there are no fields
like id or targets.

select tag: deselcting option
I am populating the options in select list B from the option selected in select list A, when a button is clicked. When a new option is selected in select list A, I want the previous option in select list B to be deselected. The value for these select lists is being stored in the session.

I was wondering if there is a way that I can call a method from my action class to achieve this. Is there a way to set the onchange attribute to a url that will call a method in my action class? Or is there another way I can get this to work. Thanks!

Re: ServletOutputStream
Thank you for the reply. I know my action can only return one response.
However I want to avoid saving my file somewhere on the server and would like
the 'File Download' dialog to appear when the file is ready. How can I do this
in struts 2 while still forwarding to a 'status completed' page? Would it be
possible to store the file data in a session and somehow have the File Download
dialog show up? If so I am not sure how to do that.

Your action can not generate two responses (if that's what you asking).
If you forward to a 'status completed' page, then you need to save
your excel data somewhere to not loosing it.

I created a small webapp that extracts data from a DB, creates an Excel file
from that data (using Apache POI), which then streams the file to the end
user's browser. Everything is working fine, however I have to set the Action

'application/vnd-ms-excel'. I want to change my application so that it
returns to a 'status completed' page when the extraction is completed.
However I cannot do this when I set the return type is null. How can I do
this?
Here is my code...
public class ExtractAction extends ActionSupport {
public String execute() throws Exception {
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet prodSheet = wb.createSheet(PROD);
HSSFSheet devSheet = wb.createSheet(DEV);
HSSFSheet testSheet = wb.createSheet(TEST);
...
HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType(application/vnd.ms-excel);
ServletOutputStream outstream = response.getOutputStream();
wb.write(outstream);
outstream.flush();
response.flushBuffer();
}
return null;
//return SUCCESS
}

I put my session variable in one action class, and then redirect to another

both classes implements sessionAware.

So, scenario is like this:
MyFirstAction.method1 [put session variable] - show first.jsp - user click
on link in first.jsp page - show second.jsp - user click on link in
second.jsp - MySecondAction.someMethod is called - show third.jsp where
this session test should be done.
I hope this helps.

Re: [S2] Form doesn't redirect
I'm replying to this because it's somewhat related to an issue I'm having. Let's say I have the following control in my jsp: sx:submit type=button method=search value=Search targets=resultsDiv indicator=indicator/ This of course will update the div defined in my jsp: div id=resultsDiv/ Everything works great under normal circumstances. But let's say my session has timed out, and I need to redirect to the login page. In my circumstance the div is replaced by the login jsp, which just looks strange.

Wierd Validation
Hi
When validation succeeds on my form, I still get returned to the input
page. My execute() method does not seem to be getting called even when
validation is OK.
This is my Action (no @Validation annotation after I read that was
deprecated)
===
@Validations(visitorFields = {
@VisitorFieldValidator(message = Default message,
fieldName = surname,
appendPrefix = false)
})
public String execute() {
...
@RequiredStringValidator(message=Validation error,
key=validate.surname)
public String getSurname() {
return surname;
}
...
===
This is my struts.xml snippet, with the correct result attributes
action name=login method=execute class=loginAction
result name=success type=tileshome/result
result name=input type=tileswelcome/result
/action
In the logs, when I enter an empty surname, I see surname is invalid
when I expect. The same message is not in the logs when I enter a valid
value, so I would expect it to then drop into my 'execute' method. But
it doesn't, it just returns to the 'input' page...
Any ideas?

Disable validation when clicking back
Hi all,
I have a multi-page form bean for a 2 step registration form. In the
second page I have a back button like this:
button name=my.company.package.BACK_BUTTON type=submit
bean:message key=prompt.back.button /
/button
and in my action I check if it was pressed similarly to the cancel button:
if (isCancelled(request)) {
targetUrl = goHome;
} else if (isBack(request)) {
targetUrl = goRegisterOrg;
} else {
.
private boolean isBack(HttpServletRequest request) {
String back = (String)request.getParameter(EDConstants.BACK_BUTTON);
return (back != null);
}
My problem is, how do I disable validator from checking the form?
Currently the user presses the back
button and validation errors show up, so he has to enter some valid
values to go back. Any ideas?
Thanks
Dimitris

Re: ServletOutputStream
To send only one response it's a inherent limitation or http, so you
can only send a page, or the excel result or redirect, but not many at
once.
What you can do is put a downloading page and from that page use a
script to begin the downloading of the excel data from a different
action.
If you want to show the save data dialog, use the content disponsition header.

Re: ServletOutputStream
A solution could be this: Store the excel data in session, then in
your 'status completed' page add an onload event to its body,
redirecting to the real download action:
IIRC:
body onload=document.location.href='http://blahblah/myaction.action';
You can also add a meta in the head:

[S2] s:action not re-executed on INPUT result
(Using Struts 2.1.2) I have a little widget (for want of a better word) which gets activated on most pages by a call to: s:action name=myWidget namespace=/widgets executeResults=true / the result of that action being a small JSP that will sit snuggly inside its little box on the overall page. That little widget is, in effect, independent and clueless of its surroundings, and very happy for it all. The sole job of the MyWidgetAction is gather the latest results and make these available to the widget through a getResults() method. Here is its original entry in struts.xml: package name=widgets extends=default abstract=false namespace=/widgets action name=myWidget class=com.mysite.MyWidgetAction resultwidget.jsp/result /action /package The problem occurs when the widget appears on a JSP page with a form. When the user submits that form, if the ensuing action generates the INPUT result (say, because there was a problem with the content of the form), the JSP form page gets redisplayed, but it's clear that MyWidgetAction is not called anew, and Struts2 complains: ERROR ActionComponent:28 - Could not execute action: /widgets/myWidget No result defined for action com.infloox.tango.teaser.TeaserAction and result input If, on the other hand, I change the widget's result mapping (so as to catch results under any name): action name=myWidget class=com.mysite.MyWidgetAction result name=*widget.jsp/result /action I then get the following error: WARN OgnlValueStack:50 - Caught an exception while evaluating expression 'results' against value stack Caught an Ognl exception while getting property results - Class: ognl.OgnlRuntime File: OgnlRuntime.java Method: getMethodValue Line: 935 - ognl/OgnlRuntime.java:935:-1 ... Caused by: ognl.OgnlException: results [java.lang.NullPointerException] ... (results being the property on MyWidgetAction (with a getResults() getter) which gets called by widget.jsp.) I suppose one solution would be to put the results of MyWidget on the session; on an INPUT result, at least something would get displayed (even though not the latest results). But using the session like that seems to go against Struts2's philosophy... Another (prospective) option would be to involve AJAX over this question. Alternatively, is there a way to force a re-execution of that specific s:action name=widget?
Struts 2 And JFreeChart
Hello Everyone, Got a quick question regarding the streaming of a JFreeChart (or any image) and how to be able to handle it on a jsp. I have create a servlet that will stream out an image to the jsp using a syntax similar to (in my struts.xml): action name=testChart class=TestBarChart result name=success type=chart 350 300 /result /action So if I, in my html, created an img tag such that testChart.action , it will correctly create the chart. My problem arises when I am using it under a dynamic context. For example, if initially I submit a form button (theme=ajax targets=divTarget) then it would render new data and an initial image. If I submit the form again with different user input the data would change but the image is still the same. I assume it is the same buffered image that it first loaded, but the action itself will never get reloaded. The action would not get executed at all. My question is whether there is a way I can manually force the img tag to invoke the action itself.

Re: Strtus2 tags IE issue error loading page 200 ok
First I thought the problem was from ACEGI that I recently added to the
project. So I took all of it out .However I encountered the same problem as
above in IE. Then I thought the problem could be some leak in display tag .
So i swithced back to normal table and the same thing again.
So I realize that a Tabbed Panel inside a Tabbed Panel does not work if you
click on the parent tab 5 to 6 times. Closing the IE window and opening it
up works again for the next few clicks. It seems it has stored something in
the session or something and is not cleaning it up.
After I get the error below
Error loading
'/Dashboard/ViewOMTable.action?dojo.preventCache=1217258686015' (200 OK)
none of the tabs are working and they all show the error above.
It could be an IE issue cause its working fine in FireFox.
Any work arounds or ideas will be greatly appreciated. Thanks.

Hi,
I am new to Struts2 and I am having a problem displaying content with IE.
It works fine in Firefox.
I am using Struts2, Acegi for login, Hibernate for ORM and struts2 ajax
tags for display
I have a parent tabbed panel and a child tabbed panel.
Once I login everything works fine however after a few clicks around I get
the following error.
Error loading
'/Dashboard/ViewOMTable.action?dojo.preventCache=1217258686015' (200 OK)
I am not sure why it is working when I log in and not after a few clicks.
Again it works as expected in Firefox.
Myjsp looks like this
Parent tab has the following tab
authz:authorize ifAnyGranted=ROLE_ADMINISTRATOR /** this is for the
Acegi stuff */
s:url id=listOM value=/Dashboard/ViewManagedEntities.action /
s:div
id=OM
label =Operations Manager
theme=ajax
href=%{listOM}
autoStart=false
refreshOnShow=true
errorText=Unable to retrieve data!
/s:div
/authz:authorize
This will get the child jsp which is below which is also tabbed panel
s:head theme=ajax debug=true/
s:div id=OMpage
s:tabbedPanel id=insideOMTab selectedTab=allOM
s:url id=allOM action=ViewOMTable.action /

How easy it will be will depend on what your data model looks like and whether you have the flexibility to change it. I would suggest you start out by reading up on how Struts manages the mapping between model data and HTML forms, and especially how data conversion works. Then build a simplified prototype that works with a minimal data model and build up from there until you have something representative of the end goal.

A solution could be this: Store the excel data in session, then in
your 'status completed' page add an onload event to its body,
redirecting to the real download action:
IIRC:
body onload=document.location.href='http://blahblah/myaction.action';
You can also add a meta in the head:
head
META HTTP-EQUIV=Refresh CONTENT=0;URL=http://blahblah/myaction.action;
/head

Thank you for the reply. I know my action can only return one response.
However I want to avoid saving my file somewhere on the server and would like
the 'File Download' dialog to appear when the file is ready. How can I do
this in struts 2 while still forwarding to a 'status completed' page? Would
it be possible to store the file data in a session and somehow have the File
Download dialog show up? If so I am not sure how to do that.

Your action can not generate two responses (if that's what you asking).
If you forward to a 'status completed' page, then you need to save
your excel data somewhere to not loosing it.
2008/7/29 Mike Rooney [EMAIL PROTECTED]:
I created a small webapp that extracts data from a DB, creates an Excel file
from that data (using Apache POI), which then streams the file to the end
user's browser. Everything is working fine, however I have to set the
Action class' return type to 'NULL' since I am setting the servlet response
type to 'application/vnd-ms-excel'. I want to change my application so that
it returns to a 'status completed' page when the extraction is completed.
However I cannot do this when I set the return type is null. How can I do
this?
Here is my code...
public class ExtractAction extends ActionSupport {
public String execute() throws Exception {
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet prodSheet = wb.createSheet(PROD);
HSSFSheet devSheet = wb.createSheet(DEV);
HSSFSheet testSheet = wb.createSheet(TEST);
...
HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType(application/vnd.ms-excel);
ServletOutputStream outstream = response.getOutputStream();
wb.write(outstream);
outstream.flush();
response.flushBuffer();
}
return null;
//return SUCCESS
}
and my struts.xml
struts
constant name=struts.enable.DynamicMethodInvocation value=false /
constant name=struts.devMode value=false /

Hi
When validation succeeds on my form, I still get returned to the input

This is my Action (no @Validation annotation after I read that was

@Validations(visitorFields = {
@VisitorFieldValidator(message = Default message,

public String execute() {

Do you have a setSurname(String) method? Without it, Struts can't pass
the input data into your action.
This is my struts.xml snippet, with the correct result attributes
action name=login method=execute class=loginAction
result name=success type=tileshome/result
result name=input type=tileswelcome/result
/action
In the logs, when I enter an empty surname, I see surname is invalid
when I expect. The same message is not in the logs when I enter a valid
value, so I would expect it to then drop into my 'execute' method. But
it doesn't, it just returns to the 'input' page...
Any ideas?
If you do have the setter in your action and you're getting this, do you
have any action errors/messages showing up when you get returned to the
input page?

Strange Behaviour in FireFox3
Hi all, Was really not sure which mailing list to post to ... I have a java application that uses struts 2 (actions, etc). Every time I access a page (which goes through an action), my browser gets to that page, but then it skips (for want of a better term) onto a blank page (with the URL intact). I am using JBoss 4.2.2 GA. This problem only occurs with FireFox version 3.0.1 (the latest version). It does not occur with FireFox version 2.0.0.16, Internet Explorer or Safari. Has anyone had this problem? Cheers
Re: S2: possibly strange namespace use case
Andy Law wrote: Jeromy, That's enormously helpful - thanks. A short follow-up. Can you point me towards a description of where/when the Action object gets created and where Interceptors fit into the process. The architect's guide is a good place to start. http://struts.apache.org/2.0.11.2/docs/big-picture.html There's nothing better than a good book though. I need to understand how I'm going to get the leading part of the URL into the action object and my head really, really hurts right now... :o}. I'm wondering if an interceptor might be a better, more understandable (to me) option? If I'm reading things right as of now, the ActionMapper route will fire (and complete) before the Action object is created (since the ActionMapper decides *which* Action gets created) so my options there are to put the details of what I find in the URL path into the request object where it can be pulled by the Action (which makes testing slightly harder), whereas an Interceptor allows me to just magic the details into the Action. On the other hand, the Interceptor requires a signature on the Action which could be overruled with a Parameter in the URL? Creating a custom interceptor or custom action mapper is a fine way to go about it. The ParametersInterceptor is responsible for setting properties of your action from params in the request. There's also two other ParametersInterceptor variations; one that sets static parameters defined in struts.xml, and another that sets parameters created by the ActionMapper. You could also create your own interceptor that checks if your action implements a particular interface, and if so, extract some information from the request and sets a property. The plugins I mentioned previously do that for you in their own ways but if none are suitable then I'd probably create a custom ActionMapper that exends the default but also looks for that param in the URI and returns it in the parameter map of the ActionMapping. Hope that makes sense. regards, Jeromy Evans - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
