As mentioned before, the exception you are seeing is caused by the fact
that JPA cannot find the definition of the ProcessInstanceInfo element
when trying to persist it. These elements are referenced in the
persistence.xml configuration files.
Could you check your gwt-console-server-drools-*.war and update the
persistence.xml file in the /WEB-INF/classes/META-INF/ directory? Make
sure the following classes are listed:
<class>org.drools.persistence.session.SessionInfo</class>
<class>org.drools.persistence.processinstance.ProcessInstanceInfo</class>
<class>org.drools.persistence.processinstance.variabletypes.JPAPersistedVariable</class>
<class>org.drools.persistence.processinstance.variabletypes.VariableInstanceInfo</class>
<class>org.drools.persistence.processinstance.variabletypes.SerializablePersistedVariable</class>
<class>org.drools.persistence.processinstance.WorkItemInfo</class>
Could you also specify the OS and version of the application server you
are using?
Thx,
Kris
