better off setting it in the action
then access it thru ognl e.g.
#session.setSeeMe
http://struts.apache.org/2.0.14/docs/ognl-basics.html
if you want to see a bean described as
package package;
public class bean {
private String BeanParamName;
public void setBeanParamName(String BeanParamName){
this.BeanParamName =BeanParamName ;
}
public String getBeanParamName(){
return BeanParamName;
}
}
in your jsp use s:bean as here
<%@(protected)" %>
<html>
<body>
<s:bean name="package.bean" id="id">
<s:param name="BeanParamName">BeanParam</s:param>

If I return to the Ajax call with mapping.getInputForward() for the defined input attribute of that action processing the Ajax call, should I see changes in the session objects displayed? Because before I return I set an element in the actionForm.setSeeMe("hi"), set the session.setAttribute("actionForm", modified) and I do not see it in the display.

user_200887.ezm (zipped)Hi Martin
Thanks, however I havnt migrate to Struts2 yet. What I was hoping for was a technique to get all the session objects reprocessed upon return from the Ajax call. I am unclear that if I do the mapping.getInputForward(), does that force tomcat to reprocess and the jsp reprocess all the session objects? I have also tried returning from the Ajax call with a forward to the page and that doesnt force a redisplay of updated values. That should, correct, it is no different than any other usage and with the json result being stored in the header it will not matter for that processing.

user_200888.ezm (zipped)The form will not be updated unless you refresh the values or the part
of the page that displays the values you want to be updated. So you
would have to "manually" do this processing some returned updated
values in a json result, or by returning the result of a "partial" jsp
which re-renders the part of the page that you want to be updated, and
then replace the existing html (using innerHTML).

apologies as i thought you were uptodate on the latest version
i assume you are implementing
public ActionForward execute(ActionMapping mapping,
ActionForm form,
ServletRequest request,
ServletResponse response)
throws Exception;
the ActionMapping mapping will call findForward which will
Return an appropriate ActionForward object that identifies the presentation page to be used to generate this response, based on the newly updated beans. Typically, you will acquire a reference to such an object by calling findForward on either the ActionMapping object you received (if you are using a logical name local to this mapping), or on the controller servlet itself (if you are using a logical name global to the application).
its important to declare local variables in Action specifically:
controller servlet creates only one instance of your Action class, and uses this one instance to service all requests. Thus, you need to write thread-safe Action classes. Follow the same guidelines you would use to write thread-safe Servlets.
Only Use Local Variables - The most important principle that aids in thread-safe coding is to use only local variables, not instance variables , in your Action class. Local variables are created on a stack that is assigned (by your JVM) to each request thread, so there is no need to worry about sharing them. An Action can be factored into several local methods, so long as all variables needed are passed as method parameters. This assures thread safety, as the JVM handles such variables internally using the call stack which is associated with a single Thread.
For each request made of the controller, the method process(HttpServletRequest, HttpServletResponse) will be called.
so keep the guts of the request processing in the Action process method
http://struts.apache.org/1.x/userGuide/building_controller.html
ActionMapping considerations:
use RequestActionMapping instead of SessionActionMapping
http://struts.apache.org/1.x/apidocs/org/apache/struts/action/RequestActionMapping.html

[The standard?diclaimer that it is not a popularity contest and nothing that does the job for you is wrong.]
Would you not agree that if you are going to mock up the framework the simulation of S2 of highest fidelity is S2 itself.
IMHO?you are digging a swimming pool by the ocean to test your yatch.
I am not familiar with Selenium but anything you can do with JUnit you can do in JWebUnit since it is just
JUnit with more libraries.
I took your route or instantiating parts of S2 in standard JUnit tests and run into trouble when I moved
from 2,0,x to 2,1,x due to changes in the framework. It is a bummer when you switch versions and find
the tests are dead.

Not to pick on anyone but this isn't really a popularity contest. Different
situations have different needs and there is no reason to suggest that one
solution will work best for everyone.
At a large shop naming something "unit testing" vs "integration testing"
maybe important as it can determined who's job it is to do the work. But at
a small shop, like I'm at, it makes no difference, it's all just testing and
it's the developers job. So for me, whatever way is easiest, quickest and
gets the job done wins.
It took some work at first to figure out how to tests actions with the full
stack with junit but now that I have the plumbing figured out it's very easy
to add tests as actions are added. With junit I can easily set the database
to a know state before each test, or use mocks to simulate hard to setup
edge conditions (how easy is that to do with selenium?) Plus it's easy to
jun junit with code coverage so I can see code isn't being covered. And, as
another already pointed out, junit is fast and convienent, 2 clicks from
inside Eclipse.
I do think it is great to see that the industry (at least those on this
list) recognizes the importance of automated testing and that with Struts
you have ability to test at the isolated pojo detail level all the way
through full blow integration testing.

user_200884.ezm (zipped)Hi all,
[the standard disclaimer ... ;-) ]
migrating from one version of struts to another is not a trouble for
selenium or such a tool,
actually it even helps You to be sure that the migration didn't break anything.
But You will hit the same scale of problems when You will change
layout - all selenium tests are dead,
of course one may argue that he is able to write selenium tests that way
that it will stay alive but that will be extra effort to cope with that.
Every solution have it's own set of troubles involved.
The is no better way, i think.
We can point out pros and cons of solutions we use,
so that others could make theirs decisions based on our experiences.
Best greetings,
Paweł Wielgus.

I haven't really found that to be the case--I only rarely test deep
structure with Selenium, but instead look for the presence of specific
CSS selectors containing text etc.
That type of change is (generally) under my control, unlike a framework
change that breaks *my* tests.

user_200885.ezm (zipped)I just had a look at Sitemesh and it looks like what I want. There is one
thing that disturbs me, though, it looks as if sitemesh will build the page
every request, which causes quite some overhead, or am I mistaken there?
