Hi, I have some problems using the BPMN2.0 Modeler (Indigo) on the JPBM 5.3 FULL installer demo.

I've downloaded and installed everythng but when I try to open a diagram I receive this exception:

org.eclipse.core.runtime.internal.adaptor.EclipseLazyStarter$TerminatingClassNotFoundException: An error occurred while automatically activating bundle org.eclipse.bpmn2.modeler.ui (390).

This error doesn't appear if I work on Eclipse without JBPM Demo running. Maybe some Eclipse configuration done by the demo startup configuration.

in the biuld.xml file eclipse start up with this conf:

<exec executable="${eclipse.home}/eclipse.exe"
spawn="yes"
osfamily="windows">
<arg value="-data" />
<arg value="${eclipse.workspace.dir}" />
<arg value="-plugincustomization" />
<arg value="./eclipse.preferences.ini" />
<arg value="-perspective" />
<arg value="org.jbpm.eclipse.JBPMPerspective" />
</exec>

Eclipse.preferences.ini has this line only: "org.jbpm.eclipse/jBPM.Runtimes=jBPM runtime#./runtime#true# "

Any suggestion?

Thanks a lot

G.

Hi Guido,

I think this was reported here: by https://bugs.eclipse.org/bugs/show_bug.cgi?id=379741

Can you please try a more recent build and see if the problem goes away?

Thanks!
Bob

Had the same exception and problem. I had it on Windows 7 PC.
The problems seems to be related with the Administrator rights. You have to start Eclipse once with "Run as administrator" and create a BPMN Model / diagram. After the initial load/install of some additional features/plug-ins, it works fine the next time without having to start with Admin rights.

At least on my PC it did help.
