Actually third case with non-existing variables isn't that critical... If someone asks for non-existing variable in EL he gets exception and should do something about it (initiate it with some value or null). Returning null in Java is not a problem but it should be mentioned in javadoc... Now javadoc on ExecutionService.getVariable says only "retrieves a variable".
It's the second case that causes problems. Like in my test case where Java method can have null value parameters and I can't pass null variable from EL.
For now I use simple workaround - I created resolver class and set it in process as "resolver" variable. Now I can use it in JPDL to retrieve variables that I know can be null:
<object expr="#{resolver}" method="get">
<arg><string value="var_name_here" /></arg>
</object>
Resolver's get method just returns executionService.getVariable

[JBoss Tools] Document updated/added: "JBosstoolsVisualEditorFAQ"
by Yura Zhishko
User development,
The document "JBosstoolsVisualEditorFAQ", was updated Feb 1, 2010
by Yura Zhishko.
To view the document, visit:
http://community.jboss.org/docs/DOC-10862#cf
Document:
--------------------------------------------------------------
*Q : Visual Editor does not start under Linux*
*A* : Linux users may need to do the following to get the visual editor to work correctly on their machines.
* The Visual Page Editor (before JBoss Tools 3.1.0.M4) requires the library libstdc++.so.5. This library is contained in the compat-libstdc++-33.i386 package.
** To install this package on Fedora Core or Red Hat Enterprise Linux run the following command:
** On any other rpm based distributions download libstdc++.so.5 and run the following command:
** On Debian and Debian based distributions (e.g. Ubuntu) run the following command:
* In case you have the library installed and you still have issue with starting the visual page editor then close all browser views/editors and leave one visual page editor open and restart eclipse. This should force a load of the right XULRunner viewer.
*Q: Visual Editor doesn't start at any platform and shows message* 'The VPE editor can't be run because your system environment needs to be changed slightly'
* check is you version of studia/tools is compatible with you version of eclipse, see compatible matrix http://community.jboss.org/docs/DOC-14297
*Q : Visual Editor starts OK, but next message dialog appears:*
http://community.jboss.org/servlet/JiveServlet/showImage/102-10862-29-195...
*A* : Some functionality of Visual Editor may not work if a project doesn't have org.jboss.tools.jsf.jsfnature or org.jboss.tools.jst.web.kb.kbnature in .project configuration. To fix this problem and turn off the message box execute next steps:
* Right mouse button click on a project in Package Explorer.
* Select +Configure -> Add JSF Capabilities+ from the context menu.
* Configure your project using +Add JSF Capabilities+ wizard and press Finish.
*P. S.* If you are shure that your project does not need JSF capabilities, just disable this message box by checking "+Do not show this dialog again!+" checkbox.

[JBoss AOP] New message: "Tried everything to get Interceptor working, what am I missing?"
by Nick Dodd
User development,
A new message was posted in the thread "Tried everything to get Interceptor working, what am I missing?":

--------------------------------------------------------------
I am losing the will to live with aop. Just trying to get a simple hello world Interceptor working by intercepting public methods. Using JBoss 4.3.0, have already given up on using annotations and instead gone for the xml approach.
My Interceptor:
public class MyInterceptor implements Interceptor {
@Override
public Object invoke (Invocation invocation) throws Throwable {
try {
System.out.println("Enter the joinpoint");
System.out.println(invocation.getClass());
return invocation.invokeNext ();
} finally {
System.out.println("Leave the joinpoint");
}
}
@Override
public String getName() {
return "my.packages.MyInterceptor";
}
}
My *-aop.xml in which out of desperation I am attempting to intercept all public methods as this is the only thing that creates any output:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE aop PUBLIC
-//JBoss//DTD JBOSS AOP 1.0//EN
http://labs.jboss.com/portal/jbossaop/dtd/jboss-aop_1_0.dtd>
<aop>
<interceptor class="my.packages.MyInterceptor" scope="PER_VM"/>
<bind pointcut="execution(public * *->*(..))">
<interceptor-ref name="my.packages.MyInterceptor"/>
</bind>
</aop>
The only output I get is from Intercepting some jms classes:
12:29:35,466 INFO [STDOUT] Enter the joinpoint
12:29:35,468 INFO [STDOUT] class org.jboss.jms.client.delegate.ClientSessionDel

12:29:35,476 INFO [STDOUT] Leave the joinpoint
12:29:35,477 INFO [STDOUT] Leave the joinpoint
I am compiling my code with the aopc
Any ideas? I am clearly missing something here.
