user_189789.ezm (zipped)I am creating a new chart using the ChartFactory
chart = ChartFactory.createBarChart
(reportname,xaxis, yaxis, dataset,
PlotOrientation.VERTICAL, true,true, true);
return chart;
and I am storing it in the session. However the DisplayChart.action that is
in the image src is not called the second time on. It seems like a caching
issue.

Could not stop the browsers from caching. so added a param to the link

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

user_189792.ezm (zipped)Hi!!
I know this is not struts question but I don't know this term so I cannot
search the internet fot it.
Two users are seeing the same page (data from database), and both of them
are editing the same
piece of data however, the other user submits the changes (update/delete)
first.
I need to inform the second user that his/her data is not the latest one.

user_189793.ezm (zipped)"Optimistic locking" will give you some information. One way to do
this is to have a column in your database table that denotes a version
number, which is incremented every time the row changes. Include that
value in your form, and then you will be able compare the form version
to the database version, making sure they are the same before
performing the update.

Thanks Evans, it works well, but I decide to give up!
When I supply your solution, everything work well. But I found all the
urls , when I use <s:url action="" /> , all actions are added a
extension "." by struts. So I add
// allow a blank extension
if (!name.contains(".")) {
return name;
}else if(name.endsWith(".")){
return name.substring(0, name.lastIndexOf("."));
}
}
to your code.
But Some other thing does not work. maybe it's value stack issue, I am
not sure.
So, I will give up. I will not try to remove extensions for struts2 and
use "jsps" instead of "action".
Always thank you Evans and everyone who helped me. Thanks!

user_189796.ezm (zipped)Hi all,
Is there a way to access values in ApplicationResources.properties in
Javascript functions?
I've found a way where I can just pass a value from the app resource file as
a parameter, but discovered that I return alerts with different messages
based on some criteria.
Any ideas?
Thanks heaps

Try this

Which google apps do use Struts2?
Thanks!

user_189804.ezm (zipped)Hi, dear Struts users!
I'm trying to learn and use Struts 2 (actually migrating from Struts 1
to 2) and I have written lots of java and xml code, which should be
working. I just can't run the application! When I try to, I get this
exception:
Caused by: Bean type class
com.opensymphony.xwork2.ObjectFactory with
the name xwork has already been loaded by bean -
jar:file:/C:/Sun/AppServer/domains/domain1/applications/j2ee-apps/Extract_to_cv_2/struts2-core-2.0.11.2.jar!/struts-default.xml:30:72
- bean - jar:file:/C:/Sun/AppServer/domains/domain1/applications/j2ee-apps/Extract_to_cv_2/Extract_to_cv_2-war_war/WEB-INF/lib/struts2-core-2.0.11.2.jar!/struts-default.xml:30:72
As the exception said, I found that the struts-core-2.0.11.2.jar file
was located in two places under my application on the server. I tried
to remove the topmost copy of the file but when I tried running the
app. again I got the same exception, and found that the file had been
put back there. Then I tried to remove the struts-core.. file that was
further down, but the same thing happened! (the same exception and the
file had been returned to that location as well).
I'm using NetBeans 5.5.1 and Sun Java System Application Server 9 and
my application is an enterprise application with a web module and an
ejb module. I'm wondering whether this problem is due to that I have
the struts2 jars in both the lib directory of the ejb module and the
lib directory of the web module. This might be stupid, but I needed
the ejb module to know about the struts classes as well and didn't
know how to make them visible to the whole application.
But then again, this (having struts jars in both modules) actually
worked when I was using Struts 1.
I'm really confused about this and I'm hoping that someone can help
me! Maybe this is mostly a NetBeans issue so if someone who has used
NetBeans could answer it would be great.
I feel completely lost when it comes to this kind of things (what's
happening "behind the scenes" in NetBeans and the app. server) but I'm
willing to learn from anyone who wants to explain it to me. But please
explain it very thoroughly then.
Please help me! I'm stuck.

user_189806.ezm (zipped)Thanks Dave. Like Struts 1, I think Struts 2 tags that are not required by
the core framework are largely be ing passed over in favor of JSTL. It is
easier to use tags that are stable, standard and well documented and
duplicate tags that do effectively the same thing are confusing.
StrutsRequestWrapper exposing OGNL allows JSTL easy access to the S2 goods.
Thought (preferably without flames bro)
Peace,
Scott

user_189807.ezm (zipped)This is probably simple and I think I'm close, but I can't quite get
it to work: the proper ognl expression to use to get the value of a
checkbox w/in nested iterator tags.
I've got an ArrayList of Parent objects called parentList. Each
Parent object contains another array of Child objects called
childList. A Child object has an boolean field called "selected."
If I nest the iterators like so:
<s:iterator value="parentList" status="parentliststatus">
<s:iterator value="childList" status="childliststatus">
Then what would be the correct expression to use for a checkbox to get
the value of selected? I tried the following, but it doesn't seem to
work:
<s:checkbox name="%{'parentList['+#parentliststatus.index
+'].childList['+#childliststatus.index+'].selected'}"
value="selected"></s:checkbox>
That, in turn, produces some html like this:
<input type="checkbox" name="parentList[1].childList[2].selected"
value="true" checked="checked"
id="commentsPrint_parentList_1__childList_2__selected"/>
<input type="hidden"
name="__checkbox_parentList[1].childList[2].selected" value="true" />
But, that doesn't appear to work. I continue to get setParameter
errors when I submit the form:
DEBUG
com.opensymphony.xwork2.interceptor.ParametersInterceptor -
Setting params parentList[1].childList[2].selected => [ true ]
ERROR
com.opensymphony.xwork2.interceptor.ParametersInterceptor -

Any ideas what I'm doing wrong?

user_189810.ezm (zipped)Which version of S2 are you using?
The selected field: Is it boolean or Boolean?
Did you write a getSelected() getter? or is it an isSelected() getter?

user_189811.ezm (zipped)S2 2.0.11. The selected field is a boolean. And there are
isSelected() and setSelected() methods.
Thanks for asking.

user_189812.ezm (zipped)I re-wrote my ognl expression slightly into this:
parentList[%{#parentliststatus.index}].childList[%
{#childliststatus.index}].selected
It seems to work now. Perhaps I had a typo in my original ognl
statement? I don't know. Probably something dumb. In the immortal
words of Chris Farley: "stupid! stupid! stupid!"
