generally html 4.x but I don't think they validate. Definitely not
xhtml, no features of 5.x.

More importantly, the "xhtml theme" uses tables for layout, the
"css_xhtml theme" uses divs, spans and css2 for layout, the "simple
theme" outputs plain-old html 4 with no markup for layout and you can
customize the theme for every tag.

Hope that helps.

S2 forwards to the JSP result and without the leading slash the
container assumes it's a path relative to your package namespace

This http://www.vitarara.org/cms/struts_2_cookbook/post_and_redirect article
about post and redirect in struts 2 explains how to redirect to a
dynamically evaluated action.

However, if I use a param which references an action property called "id",
it doesn't work.

&lt;result type="redirect-action"&gt;
&lt;param name="actionName"&gt;${redirectActionName}&lt;/param&gt;
&lt;param name="namespace"&gt;/admin/holidays&lt;/param&gt;
&lt;param name="parse"&gt;true&lt;/param&gt;
&lt;param name="id"&gt;${id}&lt;/param&gt;
&lt;/result&gt;

But when I changed the property (and its getter and setter) to be called
"aid", it works OK:
&lt;result type="redirect-action"&gt;
.. as above...
..............
&lt;param name="id"&gt;${aid}&lt;/param&gt;
&lt;/result&gt;


Also (possibly unrelated), again with a property called id on my action,
when I use the &lt;s:url&gt; tag, it automatically adds the current value of
the action's id to the URL even if I don't want it to. The docs don't
mention that this should happen (it's annoying).

It seems as if naming an action property id should be avoided...

Hi Jonny,

I have id properties on actions all over my application.

I also have several actions that do a redirect to id. I think there's
something wrong with either your environment or your action that's causing
the issue.

What exactly happens when it doesn't work?

Hello,

I am fairly new to Struts. I have two applications. AppA is a Struts application and AppB is another application. I have an Action class in AppA. Within execute() method, I am creating some objects. I would like to call the servlet in AppB and somehow I want to pass these objects to the servlet in AppB. SO far I have this

  public ActionForward execute(ActionMapping mapping, ActionForm form,
                     HttpServletRequest request,
                     HttpServletResponse response) throws Exception {
...
    response.sendRedirect("/testsqlservlet/testsqlservlet?Object=" + object);
...

But this is a problem because even if I use SSL (i.e. https://) this redirect will be in cleartext and anybody can modify the "object". What are my options? I am hope I explained myself clearly.

Thanks,

Mustafa

Put it in the session?

That's not passing the object, either; that's passing the string representation of the object. A bit different.

Hi Mustafa,

if I understand you correctly you're trying to pass an object in another
webapp. That's not a really struts-usecase. I think you're looking for
a webservice or another kind of procedurecalls (like rmi).

I think you should look for axis, cxf or another project which are more
helpful for this kind of uses.

Hello Dave,
Let me try to understan what you mean.  Are you saying that I should be doing this
    public ActionForward execute(ActionMapping mapping, ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response) throws Exception {
....
        HttpSession session = request.getSession();
        session.setAttribute("Principal",principal);
        response.sendRedirect("/testsqlservlet/testsqlservlet");
...
Because this did not work. 
Thanks,
Mustafa

If they're actually two different applications, no, it wouldn't work.

Unlike the other reply I had assumed they were in the same app, but apparently you meant what you said. Things don't work like that, on several ways, so you'll have to explore other options.

Dave

I believe most servlet containers prevent sharing of session objects
between applications by default. But it probably can be configured to
be allowed (consult the documentation for your server to find out
how). A shared cache is also an option. But the easiest would be to
put them in the same application.

I'm guessing here, but maybe your issues are related to:

http://jira.opensymphony.com/browse/OGNL-141

Which has been pushed off in Xwork to 2.5:

http://jira.opensymphony.com/browse/XW-631

And which has been pushed off in Struts2 until at least 2.1.3:

https://issues.apache.org/struts/browse/WW-2128

You're welcome to update the version of ognl you're using in your own
app (but remember to add javassist if so).

Theoretically this translates to a straight lookup for #object, then
getA().getB().getC().getName()...
If A, B, and C are just accessors, it should be fast. If they do much
work to determine what to return, you're doing that work 2*N times
(where N is the number of times through the loop) instead of just
once...why would you put a long lookup like that in an iterator if it
doesn't change with each iteration?

Hi,

> How the validation should be done for fields which are only displayed in certain conditions? If I do this through the XML file the validation is done all the time even when the field is not visible.

You can implement validate() or validate<ActionAlias>() and remember
to implement Validatable interface.

You either do conditional validations, implement custom validators, or as Lukasz suggested write your own validate() method. When validation is very complex the last may be the best options.

Hello,

I recently have been working on a struts 2 + spring 2 + hibernate system and
have come across a problem that I never have when just working on a struts 2
system.

I have two action classes, one that prepares the jsp and populates some
selects for the user to choose from, and another that takes and processes
the information. When the first action is invoked the result will bring it
to the tiles (type="tiles") on the struts.xml file. The second action will
take the form information and do a search, in this instance I am using
hibernate to access the db.

I would do the search and when I get the list of persistent values I would
chain (type="chain") to the first action class with the list of persistent
objects and would then return to the tiles and the jsp showing the values
that I found on the search.

The problem I am having here is that because of the chain (or similarly a
redirect action), the list of persistent objects will re-appear if I went
off to some other action classes and came back. What I mean by that is if I
had a list of 10 values that I searched for and displayed them, if I went
to some other jsp/action class and came back to that same one the same exact
10 values are being populated.

At that point when I would return to the original jsp the value stack should
have removed them completely, which it has. There is no trace of the list
of persistent objects on the value stack as well as not being a cache
problem. The situation arises when the chain occurs, I have worked with
just a struts 2 system for a year now and never had this problem.  I know
this is the case because when I get rid of the chain and invoke the tiles
from the second action class the problem goes away.

I am not too sure why these values persist throughout the session and why
they re-appear even though they are not on value stack. I have found a very
similar problem in which this person found that the problem occured during
an action redirect at
http://www.nabble.com/Struts-2-%2B-Hibernate-question-td17527841.html
http://www.nabble.com/Struts-2-%2B-Hibernate-question-td17527841.html

On a side note, just remembered, when I would want to populate the list
after its already been populated (so the user will search once then decide
to search again) the values wouldnt change even after setting it to a new
list. If I set that list to null first then changed it, the values would
change, not sure if that makes much sense.

If anyone has an idea on what can be causing this I would greatly appretiate
your help.

Hi Sarath,
where from this deploymentVersion is from (action, session)?
Such construction works for me in many places, so i would like to

Now, server-side validation works!
I changed ActionErrors class with ActionMessages class into my java
validation method and into "validator-rules.xml".
The only problem is that
Resources.getActionMessage(request, va, field)
method in my custom validator class is deprecated and I don't know how to
replace it.
Can you give me any suggestions?


On the client-side, I have the same problem.
I see a javascript warning in browser: "twofields is not defined".

I can't understand where is the problem.
