3:49 a.m.
Good day,
Currently I'm working on a RCP project with jBPM 3. At this very moment I'm stuck
while trying to execute a process. The processDefinition.xml starts executing and at a
certain moment, when it reaches a part where a Script object is started, a
DelegationException is thrown.
Prior to this exception, I noticed that BeanShell did not seem to be able to resolve the
OSGi classpath I use where certain source/config files are located.
Debugging the code learns that the cause is located somewhere in the integrated BeanShell
code (can't tell where exactly, as I don't have the source code available); it
seems that BeanShell does not use proper classpaths (confirming OSGi standards), while my
RCP based project does.
As far as I know, BeanShell does 'something' with the classpaths/classloaders
which seemingly affects the process in a negative way.
Can anyone suggest a way to make jBPM/BeanShell understand how to use the proper
classpaths or other, if the probable cause does not concern the classpaths/OSGi aspects,
possibility?
Thanks for the effort! Hope that I provided enough info about the problem here, if not
then just yell ;).
=== Environment ==============================
- jBPM Version: 3
- JDK: 1.6.0_17
- Configuration : Use the default jbpm.cfg.xml with jbpm.jar lib, no custom config file
used.
- Libraries : using all default libraries from jBPM, no custom or changes made.
