Thanks ramram!!! That defenitely helped to get rid of that error. Now I can
see my process in gwt-console, which is very encouraging :)

But when I try to start the process I get the following error:

----------------------------End Of Error----------------------------

I read in another post that this problem is because the persistence.xml is
missing the following entries:

    <class>org.drools.persistence.session.SessionInfo</class>
    <class>org.drools.persistence.processinstance.WorkItemInfo</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>

I've tried adding this entries to gwt-console-server persistence.xml but it
is not working so far.

I also see a message in the log that reads: 
WARN  [org.jboss.bpm.console.server.plugin.PluginMgr] Unable to load plugin:
'org.jboss.bpm.console.server.plugin.ProcessEnginePlugin'

I am wondering if this has anything to do with the error I get when trying
to run the process.

Any ideas for this issue?

I appreciate any help!!!

Thanks,
