[jboss-user] [JBoss jBPM] - ClassNotFoundException loading my ActionHandler
Jbpm 3.1.3. Using jbpm.sar in my AS I am trying use Jbpm in my webapp. I created an
ActionHandler and assigned it to a transition. I get the following exception:
2007-01-28 09:15:46,656 ERROR [org.jbpm.instantiation.Delegation] couldn't load
delegation class 'com.eLynx.BPM.Handler.ConsentHandler'
java.lang.ClassNotFoundException: class 'com.eLynx.BPM.Handler.ConsentHandler'

My ActionHandler class is in the war file (classpath) of my webapp. Does it need to be in
the jbpm.sar deployment? That seems pretty weird. I have my logging configured so that
my application logs to its own file and I noticed that this exception logs to the server
file, not my app log, which suggests to me that the jbpm service is what is trying to
instantiate the class and its classloader knows nothing about this class.
Is there a way around this. I don't want to have to put every custom action handler
in the jbpm.sar. I have existing code that I am trying to wrap with jbpm to get better
flexibility in managing process flow. Should I not use jbpm.sar and instead run jbpm
embedded in my application in the manner of the simplewebapp example found on wiki? We
have several webapps whose functionality we want to bpm enable and that doesn't appear
to be the optimal way to approach it.
Thanks for all input.
