JbpmJobExecutor throws NoClassDefFoundError when restoring d

[dleerob]

I use a MySQL 5 database with Jbpm, running on tomcat 5.0.28
I have nightly "live" backups of the MySQL jbpm db which runs.

When restoring a backup to a different machine/environment, the JbpmJobExecutor thread throws a NoClassDefFoundError exception, after which my system seems to be pretty much useless.

If looking at the db table 'jbpm_job', the LOCKOWNER_ column specifies the ip address of the original server/machine that the database resides on. If I modifiy these ip addresses to be the same as the machine this db is now on, everything seems to work fine.

Is it okay to just modify that column/value like that so it runs on the different machine? Or is there a 'proper' way if backing up and restoring to a different machine?

Thanks.

Hmm... never ran into this, but from what I've read following all topics etc, it might just be that indeed changing just the value of this column is enough.

otoh, is it the ip addres of the db machine? or are the db and appserver running on the same machine? afaik, it should be the ip address of the server the jobexecutor is running on.

The db and appserver are running on the same machine.
It would be the ip address of the appserver, as you said.
