hi,
I have a similar problem but the error details are different.
I do have library bsh.jar in the libs but here it seems a different story. thank you in advance for the help.

HTTP ERROR: 500

@quaglia
Can you run most simple zul created by zk studio?
It has EL inside it.

<?page title="Auto Generated index.zul"?>
<window title="Hello World!!" border="normal" width="200px">

</window>

If you can run it, but can't run your own zul.
There should be something wrong in you zul, please provide us example to deplicate the issue.

thanks Peter.
the visual editor works on 'normal' stuff
the problem is the integration with the spreadsheet component. I was playing around with an example introducing it and the component was the cause of the exception.
this happened with Eclipse Ganimede with the newest ZK studio.

by the way,I have not been able to install ZK studio on Eclipse Galileo (both with the update site and with the local archive) :

An error occurred while collecting items to be installed
session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.provisional.p2.engine.phases.Collect, operand=, action=).

Hi PeterKuo,

I've exactly the same error posted by quaglia.
The problem is not if we can run .zul file or not , but with the ZK visual editor.
When I open Windows -> Show View -> ZK Visual Editor,

I'm getting exactly the same error stated above.
I installed everything as stated in the quick start guides. But still having sooooo many issues.

I've these jars in my project's Web-Inf/lib folder;
bsh.jar, commons-fileupload.jar, commons-io.jar, dojoz.jar, fckez.jar, Filters.jar, gmapsz.jar, groovy.jar, jcommon.jar, jfreechart.jar, jruby.jar, js.jar, mil-sources.jar, mvel.jar, ognl.jar, timelinez.jar, zcommons-ef.jar, zhtml.jar, zk.jar, zkex.jar, zkmax.jar, zkmob-sources.jar, zkplus.jar, zml.jar, zul.jar, zweb.jar.

What else should I add to make it work?

My requirement is to work for a ZK Mobile project. All I need is to be able to build and execute .mil files on Blackberry.

There's hardly any documentation or examples on ZK Mobile. And the forums activity is soooo slow. I'm really having trouble. Can you please guide/
