Re: how to avoid creating new Action class instance for every request in STRUTS2
You're probably right, whenever the Action is created, it's initialized. In struts 1, since the Actions didn't go away, any data was retained. This was usually the source of many, many bugs. It's a very rare condition when you want the data from one invocation of the Action to carry forward to the next, especially since in a multiuser system, it may not be the same user that hits the action twice in a row. So the second user would get the first users data. In order to help prevent these errors, the designers of Struts 2 made a conscious decision to create the Action instances as needed. So to emulate what you had in Struts 1, where everyone shares one pool of data from the action, just put your list in the Application scope (ServletContext) and retrieve it when you initialize your Action. If you really only want this to allow each user to maintain their own list (not like the Struts 1 implementation), you could put it in Session scope instead.

how to avoid creating new Action class instance for every request in STRUTS2
implementation: I have .jsp in which i have two text box and a Add button. whenever i enter something in the two text box and click on Add button the values needs to be added to the html table which is right down the entry area with two text boxes. Whenver i Click on add i am calling a Action class where i have a colection object in which i add the two text box values to the collection object and on SUCCESS comming to .jsp i iterate the collection object and display it in the .jsp. Problem facing: Whenever i call the action class and i am adding, its adding and displaying in the html table but the next time i add the previous values in the collection gets removed At a time only one object is there in the collection. The same implementation i did it in Struts 1 it was working fine, but in struts 2 its not retaining the values in the collection.Is it because for every call a new Action instance is created in Struts2? Is there any intercepto i need to use? Please provide me a solution to implement this functionality in struts 2 Thanks in advance Jose -- View this message in context: http://www.nabble.com/how-to-avoid-creating-new-Action-class-instance-for-every-request-in-STRUTS2-tf4538022.html#a12952131 Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [S2] ScopedModelDriven issues [newbie]
Does anyone have a working example using the scopedModelDriven interceptor to
work for a session bean?
I've tried with the following:
1. define interceptor in struts.xml
...
session
myForm
model.MyFormBean
...
2. define interceptor-ref for action(s) in struts.xml
...
3. Action class extends ScopedModelDriven
public class MyAction extends ActionSupport implements
ScopedModelDriven {
...
private String scopeKey;
private MyFormBean model;
...
public String getScopeKey() {
return scopeKey;
}
public void setScopeKey(String key) {
scopeKey = key;
}
public void setModel(MyFormBean model) {
this.model = model;
}
public MyFormBean getModel() {
return model;
}
}
4. attempt to populate a property of MyFormBean via JSP form:
With this setup, the model is persisted in the session, however, none of my
properties are populated or preserved in subsequent actions/screens.
I'm sure I'm missing something trivial or completely misunderstanding
something but any help is appreciated.
Thanks,
Grant

complex tag nesting?
I'm pretty sure I remember someone asking this question before, but I was unable to find it either in my archives or in nabble... I basically want "includeParams" for a specific parameter, and I thought I could do it just by conditionally including the parameter like so: It doesn't work. I guess I can always include the param and just change the value based on a condition: '> but I wanted to ask if there's any sensible way to make the first solution work? I understand that the s:if tag is conditionally allowing the body to be added to the output, which is different from conditionally deciding whether or not to execute the body, and I understand that it's likely the s:url tag understands s:param children but not s:if children... ...but I could see a desirable use-case where someone wants to nest an s:iterator inside a s:url, too, and it would be nice if these types of constructs could work... -Dale - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

In your struts.xml for the action mapping add the roles interceptor as following. method="list"> /email/listemail.jsp name="allowedRoles">Administrator,Role2,Role3,Role4 ..

Can anyone assist with this? -Original Message- From: Givler, Eric [mailto:[EMAIL PROTECTED] Sent: Saturday, September 22, 2007 1:25 AM To: user@struts.apache.org Subject: [s1.35] Need help with Struts and Modules Hello, Let me just say that I'm struggling at times writing my first production Struts application. The issue that I'm trying to wrestle with now is that part of the application requires security, and part of it should allow general access to the public. This sounds like a case for modules (I think). So, I separated the code into a main folder, and then two other folders (the secure, and another subsystem which is not secure). If I need to have the unprotected system and the protected system SHARE some code as well, I'm assuming I have to keep that in the default module, since otherwise, a security constraint would pop up when the unauthenticated user tried to hit those pages. If I'm in the authenticated module and I want to start a process that's defined in my default module, how would I do that? That is, would it be as simple as adding a link to my JSP in my auth'd app pointing back to the unauth'd: Start an application process Now, I have two users running app entry (one auth'd and one not). If they start an application and cancel it, they should return to their prospective "subsystem". What am I setting up in my struts-config.xml file(s) to handle this, and then in my action class? Can you be specific on this (with an example of code)? I really appreciate any help on this one - Thanks much, Eric

Re: OT, ajax form submission
I really recommend using something like Prototype to do your Ajax
stuff. There's no need to reinvent the wheel and introduce countless
bugs in the process, Prototype is tested for all relevant browsers and
it'll take you 10 minutes to do what you're trying to do if you use
it:
http://www.prototypejs.org/api/ajax/request
http://www.prototypejs.org/api/ajax/options
Good luck,

RE: [ot] help on generics...
Unfortunately, the short answer is that you can't.
The compiler will yell at you about class literals for generics because in Java
they are implemented using erasure. This is in contrast to C# (which is where I
first learned how to use generics) and annoys many people to no end. It was
done to maintain binary compatibility between generic and non generic versions
of classes and to ensure generic classes could run on JVMs that have no
concepts of generics. The compiler basically makes all your generic methods use
Object and inserts casts that are garneted to be safe by the compiler.
At run time the method
Optional opt = composite. getFeature();
Looks like
Optional opt = (Optional) composite. getFeature();
To the JVM (more or less)
T.class doesn't work because class literals are resolved at runtime (even
though as a programmer you know what they are at compile time). Since a T type
is really an Object type, T.class makes no sense and doesn't give you the
object you want.
For the method you describe, you can still avoid the casts using generics but
you need a parameter that takes an object representing a type, not a parameter
that IS a type, since type parameters aren't really method parameters in the
normal sense.
public T getFeature(Class clazz) {
return aggregators.get( clazz );
}
Then you can call the method like so
Optional opt = composite.getFeature( Optional.class );
And there are no casts required.
This comes from the fact that class objects are now parameratized to there
class. So for example:
String.class
Will return a Class object.
It doesn't seem ideal but it's as close as you can get with the way Generics
are implemented in Java. You will have problems though if the caller of your
method uses type parameters instead of explicit types. For example:
public class OptionWrapper {
private final Composite composite;
public OptionWrapper(Composite composite) {
this.composite = composite;
}
public T getOpt() {
//needs a class object!
T opt = composite. getFeature();
return opt;
}
}
Hope this helps.

Thanks a lot for those detailed examples !
I don't want to setup a factory, but to expose internals as optional features :
my class is a composite, with a map of "features", where the key is

I'd like to get an optional feature using :

How can I then get the Class object used as generics type, to get it

Struts2 ... SecurePlugin?
Hello, In Struts old we used to do this in struts.xml: What is the struts 2 way of securing your actions? Is there a predefined interceptor or packaged plugin I can use? Any pointers. Thanks, Mufaddal.

Re: autocompleter
This was just fixed on trunk, see WW-2220. There will be a "keyValue"
attribute to set the initial value of the key. The "key" attribute is
something else, not related to the autocompleter's "key"

Re: autocompleter
Hi Meissa,
Yep it is possible ... assuming you provide:
then include in the rendering Action associated to this JSP the
following two bean property getters:
// will provide the default display value that the user sees
public String
getSomeProperty()
{
// ...
}
// will provide the key corresponding to the default value the
// user sees
public String
getSomePropertyKey()
{
// ...
}
Any other way to specify initial values e.g. using the autocompleter
attributes "key" and "value" will not work (because of some bug) the
key will not be posted to the processing action. The only way to have it
working is NOT to provide these attributes and use the getters from the
page display rendering action.
i.e. avoid doing this:

Struts Tag Question
I have a java.util.Map in my action (value stack) and I simply want to print it's contents in an HTML table in my JSP showing the key value pairs. However, I am having an issue figuring out the proper syntax. My initial approach is to iterate over the Maps keys and then during each iteration, call the maps get() method passing the key to it which is not working. Could someone who has done this before show me the struts tag syntax that would accomplish this? Thanks. Marco

Martin, Our codebase is on 2.0.8 now (i know we need to upgrade asap) and we need ti finalize some other work (our real jobs) before we can run the regression tests (selenium, junit) against 2.0.9.

Re: Breadcrumbs
Thanks Brian -- I wanted it be automatic and work easily with Struts 2. After probing and searching, I realized there was no such animal so I wrote a plug-in. This was a testament to just how flexible the Struts 2 framework really is! I wrote a Bread Crumb interceptor with only a few lines of code and added it to the stack. After playing with it for awhile, I added several ways to configure it with XML (at the interceptor level) to specify exactly how a web site might like this feature to work. I loved Struts 2 before and now I would marry it! Scott

Hi Jennie,
I am fairly new to Struts 2 but you can certainly do action wildcard
mappings with it, such as:
/{1}.jsp
where foo.action would map to foo.jsp.
However, my guess is that what you are asking for is a little bit more
advanced (and judging by the "*.do" you are not using Struts 2). You
might be better to look at using mod_rewrite on apache if you can.
Alternatively you could create or use something like the URL rewriting
servlet filter below.

If you want to handle the before and after topics separately you can do
something like this. Note I am publishing a separate topic for the form
(submitForm) and then handling it using some javascript code
listenTopics="/refreshTree" executeScripts="true"

targets="workspaceAjaxContent" executeScripts="true"
loadingText=" " cssClass="submit">
dojo.event.topic.subscribe("/submitForm", function(data, type, e){

When a div tag contains the "listenTopics" attribute, the associated

which invokes the notifyTopics??
listenTopics="/refreshTree" executeScripts="true"

When I submit the form it invokes the action form and i have 2 threads

Re: [ot] help on generics...
Thanks a lot for those detailed examples !
I don't want to setup a factory, but to expose internals as optional features :
my class is a composite, with a map of "features", where the key is
the feature interface (
Map)
I'd like to get an optional feature using :
Optional opt = composite.getFeature( Optional.class );
The generics way seems to be :
Optional opt = composite. getFeature();
How can I then get the Class object used as generics type, to get it
from the map ?
public T getFeature()
{
return aggregators.get( T.class ); // Doesn't work
}

Both of the above constructs should execute in no time.

You can always measure the time that your JSP page took
