Open Source Document Management System | OpenKM

hi,
I have designed a workflow process in eclipse jpdl designer and some java classe, that i want to use in process. I have exported PAR package and upload proces definition in OpenKM. I have a problem because process instance cant access java classes. Is that possible, openKM do not upload java clesses to jbpm engine??

In the process definition deploy screen (in Eclipse, I mean) have you checked to include the java classes? By default is unchecked and classes are not included in the PAR archive.
