Hi Sam,

is that the full log that you have or was it trimmed at the end? In that log file you can see that the process was executed once: is that the one started from OpenIDM UI? If so, after that there is no sign of any error in the log. Could you give me some details about what it means that it does not work from Activiti Explorer? Where does it fail? What kind of behavior do you get?

Also note that questions about Activiti and OpenIDM integration could be sent to the OpenIDM mailing list:

Hi Orsi,

Thank you very much for your help! I've attached the whole log file.

I have no idea where to get the exception message in Activiti Explorer and I just write down a few lines.

Exception
com.vaadin.event.ListenerMethod$MethodException
Cause: org.activiti.engine.ActivitiException: problem evaluating
I'm unable to see the rest of codes.
I've configured the pom.xml and added the dependency of slf4j and log4j, should I have to cofigure a path or file somewhere?
I'm still unable to see any log file related to Activiti Explorer except some pieces of lines in catalina.out.

Yes, it's the same process both in OpenIDM and Activiti Explorer.
I followed the OpenIDM Integrators Guide and when I logined into Activiti Explorer and clicked the Processes -> Process Definitions, and then clicked 'Osgi Process ', tried to start it, a tiny exclamatory mark showed up on the 'Start Process' button. I hover my mouse cursor over the button, the Exception message showed up.

I've also posted this thread into OpenIDM forum at the same time yesterday. So far no reply.

Thanks again,

Sam

Well the error is right there, but I don't know Forgerock at all to know why the nullpointer is happening there. Seems like some json is not passed or a part of a json is not passed?

Thanks a lot.

OpenIDM controls all the processes by using JSON files. I'll check them and see if it works. I didn't change any json file yet.

By the way, would you please tell me what the open source Authentication product like OpenIDM that you're using is?
Is there another better choice?

Should that be a subsequent error? It seemed the original error should be
<code>
Feb 10, 2014 11:14:39 AM org.activiti.engine.impl.interceptor.CommandContext close
SEVERE: Error while closing command context
org.activiti.engine.ActivitiException: problem evaluating script: javax.script.ScriptException: org.forgerock.openidm.objset.InternalServerErrorException
</code>

It's weird that Osgi process has been started in OpenIDM and I've seen it's working by checking Apache Felix Web Console Bundles.

Would you please tell me how Activiti Explorer works with other modules like OpenIDM? What's the interface protocol?

Thank you very much.

No, if you look at the stacktrace, the lowest cause is the json exception.

Activiti simply wraps it when closing the command context. So for now, Im still thinking the problem lies there rather than anything else.

Thanks jbarrez for your reply.
Is there a way to find the information of this json file? Name or piece of node?
How could I know which file causes this issue?

I uploaded the json file which was mentioned in OpenIDM manual, would you please take a look for me?
