Hello,

paste the whole stacktrace of the exception from the server.log (should be in jbpm-installer/jboss-as-7.0.2.Final/standalone/log/server.log) including the block with the last 'Caused by' statement.

Hi there,

I had the same issue while refreshing process list in the jBPM console while having invalid process deployed into Guvnor (don't ask me how I was able to built package).

Removing this invalid process from Guvnor makes the console working again properly...

Hope this help

This is so annoying working with jbpm 5.3!

For every next step, a new issue rises which is faced by all and yet not been resolved.

I have tried a sample process with a single user task in the guvnor-web designer and build it. After accessing the console, I have faced many errors.

Right from  "java.lang.IllegalArgumentException: org.hibernate.QueryParameterException: could not locate named parameter [userId]"

to the error posted in this thread.

Series of errors:

1) "java.lang.IllegalArgumentException: org.hibernate.QueryParameterException: could not locate named parameter [userId]"

     Resolution: replaced jbpm-human-task-core-5.3.0.Final.jar at locations as suggested in post:  https://community.jboss.org/thread/203763?start=15&tstart=0

2) "Could not connect task client HornetQ(127.0.0.1:5445)" in the console with "Servlet.service() for servlet Resteasy threw exception: org.jboss.resteasy.spi.UnhandledException: java.lang.NoClassDefFoundError: Could not initialize class org.jbpm.integration.console.StatefulKnowledgeSessionUtil$SessionHolder" in the server.log
