Hi,

I have a Category business object looking like this:

------------------------------
public class Category {
    private Category parent;
    private Set<Category> children;
    //...
}
------------------------------

I have a form that allows me to edit in information about a different
object. This object is linked to zero, one or more Category objects. What's
a good way to display this? I though of check boxes. The check boxes must be
checked if the object is already attached to that Category.

To me this seems to be kinda impossible right now. Any suggestions?

I have been trying to start a new project using struts 1.3.10 on Websphere V6.1. However, I have been unable to make tiles work with struts 1.3 . I get an exception as follows:

Stack Dump = java.io.FileNotFoundException: mainPage
......

I have downgraded to strtus 1.2.9 and everything is working as expected. My two cents are this can be one of those Websphere bugs [similar to the one I experienced sometime ago when I used Struts 2.1.x]. However, to be on the safe side, I am asking struts user group to see if anyone else has experienced the samething on Websphere [probably found a way around it] or not?

Antonio:

Thank you for the url, I was missing the tiles config. It would be great if information related to struts 1.3 is put under user guide for struts 1.3 as I started with 1.3.10 blank.war.

Once again, thanks for the url.

I am using the leading "/" and it still seems to be using the namespace! I
renamed the ftl folder pages to be config to match the namespace, and it
works fine. Is there another way? I originally tried with and without the
leading slash and ultimately had to make this change to get it to work. I
was a little puzzled by this. Since it is a plug-in, I'd hate to require
additional configuration settings on the part of the developer. It should
be plug-n-play man!

P.S. By the way... which one's Pink?

Peace,
Scott

When my index page loads, ajax requests are posted to the statusAjax page
with a parameter of door.id equal to x for the doors.

That works fine, and is a POST.

When I click on an icon, it posts to the identical action, to either lock or
unlock. When the action is done, I redirect to the status action (just like
when the index loads, except with a GET this time). I get an exception
setting the door.id, but the url shows that the get value and property name
are right for the redirect action. Can someone explain what I am doing
wrong? The action works on the index ajax calls, but future clicks give me:

you are confusing static parameters with request parameters. You *do
not* need to add "param" to your action mapping to get the parameters
bound the class fields. You add "param" to your action mapping to
"inject" things into your action, IoC style, but is is not needed for
request parameters. So if you have something like:

<param name="cmd">bbbb</param>

and you call the action like /action?cmd=aaa, then setCmd(...) will be
called 2 times, one for the static param("bbb"), and another time for
the request param ("aaa").

Ok I see it now. The staticparams interceptor adds the params to the
request params map, so that would explain why it is called again. We
could add a setting to the result to prevent this if needed.

I would argue that each of {staticP,actionMappingP,p}arams should both
set the discovered and acceptable params on the action and add the
discovered and acceptable params to the map so that ParameterAware
actions can be handed the full set of parameters detected by the
interceptors. It sounds like params is setting both those discovered by
it and those that already managed to get into that map before it runs.
This shouldn't be a big deal as setting a parameter should be
idempotent, but I would agree that this is a bug.

-Dale

We cant change it because it would break backward compatibility. I
added a "merge" parameter to the static parameters
interceptor(defaults to true):

http://jira.opensymphony.com/browse/XW-709

fixed in xwork trunk. Thanks for reporting!

Greg, I didn't want it to come off as a popularity thing, my point was
that a lot of us might be against excessive JUnit testing because of
how much of a PITA it can be within the Struts codebase.

I agree that whatever is quickest and easiest wins, and I would add
that you also have to try to consider the best tool for the job.

See, this is where I think you are missing my point. I am trying to
indicate that with a tool like Selenium, you don't *need* to setup
mock objects, you are dealing with a real, live deployment (hopefully
on a dev-testing system). You simply deploy your app, then tell
selenium to run your tests. Here's my issue with setting up mocks and
trying to learn how to push actions all the way through the framework
from a unit test. How do you know that we won't introduce changes that
break your whole setup? I haven't read the article you have, but what
I am trying to say is that if you want to test the whole flow of the
framework... Why not use a tool that lets you script an interaction so
that you can just replay the script? There's no need to setup mocks,
etc. You are likely developing your apps by having the code in one
window and a browser in another. So, why not take the spots that have
been known to cause trouble, and script an interaction with it so that
each time you run your tests, you can make sure that it is still
operational.

If you aren't familiar with Selenium, you may be completely
misunderstanding why I think it's a better approach. You might install
the selenium IDE and then run the selenium tests that are setup in
sandbox/s2-jquery-showcase, just to see what I'm talking about. And,
if you're curious, with m2eclipse and the Selenium Maven Plugin, you
are likely to have it two clicks away as well.

Of course you're right Greg, it's not a contest... no right or wrong
here. I am glad to hear all the views coming from everyone and
commiters too.

Well, my original motivation was to learn how to do this kind of
tip-to-tail, all inclusive testing, with the interceptor stack
involved.

For example if I want to unit test an action within a secure package,
that action requires the authentication interceptor to execute first,
so, to do my testing I thought that the full fledged testing was
necessary, to include my required interceptors. But from what I have
been researching and hearing in this conversation, I believe there is
a way to provide a "mock" object acting like my authentication
interceptor and thus not need to include the interceptor stack.

Also, I am not sure about testing a class which implements other
struts interfaces like preparable, sessionaware, etc. Would that make
a special case?

Just a quick question to Wes: In your upcoming book, which is in the
MEAP phase, there is an appendix titled Unit testing with JUnit and
TestNG . Is there any plan to include some examples describing the
different kinds of unit testing that can be done? I am looking forward
to taking a look at it.

Yes, it will be very high-level, meant to demonstrate how easy testing
is meant to be. IMO, a lot of the people that are still shying away
from unit testing do so because (they believe) testing is difficult to
setup and a hassle to maintain. There will be examples for junit,
testNG, and how to inject with spring as well as using maven to
automate the running of tests. I'll also discuss the various testing
strategies (integration vs. unit) and basically evangelize the same
position I'm arguing for on this thread :-D

So is this the only resolution out there? To lazily initialize the contents I
know I'll need before the container decides to trash the persistence context?
There is no way to extend the context such that the lazy initialization will
work when rendering the view?

I'm not using Spring. As such, I'm not familiar with this filter, but from the
description, yes, that is what is needed. However, the app server manages the
transactions, and injects the EntityManager when needed. I can do a JDNI lookup
and receive an EntityManager, but I'm unsure of where this would actually need
to be placed (an interceptor? in the action, to be placed on the stack
somewhere(so a reference is held?)).

This is not exactly what you want, and it's based on Hibernate and a
hibernate session, but if you think of hibernate sessions as jpa EMs,
then you can just make the appropriate changes to this and at least be
further than you are now.

Thanks Wes, I don't know how I didn't catch that page when browsing the docs.
That's actually very similar to the interceptor I just started working on. I'll
let you know what I come up with.
