Hi, I'm new in the JBOSS world so I'm sorry for my (stupid?) questions :)
I installed JBoss 5.1 and jbpm-gwt-console.war and jbpm-gwt-console-server.war (JBPM
5.1).
The Drools versions is the 5.2 (this is provided in bundle with the JBPM downloaded
stuff).
Unfortunately, during JBoss startup the following error occurs:
+Caused by: java.lang.ClassNotFoundException:
org.drools.persistence.processinstance.WorkItemInfo+
I checked in the drools core jar provided by jbpm and this class is not present.
I added drools-persistence-jpa-5.0.1.jar (cause this jar contains the missing class) and
this time the following error occurs:
+java.lang.NoClassDefFoundError: org/drools/marshalling/impl/ProcessInstanceMarshaller+
cause there is no suck class in the Drools jars. So I added also drools-core-5.0.1.jar
(cause it contains the last missing class) and no problem occurred during startup.In this
case, when I ask for the service
http://localhost:8080/gwt-console-server/rs/process/definitions
http://localhost:8080/gwt-console-server/rs/process/definitions the following error
occurs:
+java.lang.NoSuchMethodError:
org.drools.util.ChainedProperties.<init>(Ljava/lang/String;Ljava/lang/ClassLoader;Z)V+
It seems as a different version of the Drools library is used instead of the expected one
(probably this is due to the adding of the jars I did to solve the first two missing class
exception).
I have no idea how I can solve it...Any help will be appreciate.
Thanks in advance,
Pierpaolo

I just found out there is a persistence.xml file in the folder
jbpm-gwt-console-server.war\WEB-INF\classes\META-INF containing the following rows (as
provided by the jBPM installation):
+ <class>org.drools.persistence.session.SessionInfo</class>+
+
<class>org.drools.persistence.processinstance.ProcessInstanceInfo</class>+
+ <class>org.drools.persistence.processinstance.WorkItemInfo</class>+
+ <class>org.jbpm.process.audit.ProcessInstanceLog</class>+
+ <class>org.jbpm.process.audit.NodeInstanceLog</class>+
+ <class>org.jbpm.process.audit.VariableInstanceLog</class>+
Of course the SessionInfo and WorkItemInfo are specified in a bad path.
I modified this file and now I have only two rows:
+ <class>org.drools.persistence.info.SessionInfo</class>+
+ <class>org.drools.persistence.info.WorkItemInfo</class>+
I started JBoss removing all of the Drools5.0.1 jars I added before and no error occurs
like before but another error arose:
+org.hibernate.hql.ast.QuerySyntaxException: ProcessInstanceInfo is not mapped [select
processInstanceInfo.processInstanceId from Proc+
+essInstanceInfo processInstanceInfo where :type in
elements(processInstanceInfo.eventTypes)]+
I think the problem is the missing of a row related to the ProcessInstanceInfo but
actually I cannot find it in the Drools jars.
What did you change in this file according to Drools5.2?
Thanks,
Pierpaolo

Other update for you :)
I added the followinf rows in the file
jboss-5.1.0.GA\server\default\deploy\jbpm-gwt-console-server.war\WEB-INF\classes\META-INF
<class>org.drools.persistence.info.SessionInfo</class>
<class>org.drools.persistence.info.WorkItemInfo</class>
<class>org.jbpm.process.audit.ProcessInstanceLog</class>
<class>org.jbpm.process.audit.NodeInstanceLog</class>
<class>org.jbpm.process.audit.VariableInstanceLog</class>
<class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>
and no error during startup :D
When I click for http://localhost:8080/gwt-console-server/rs/process/definitions
http://localhost:8080/gwt-console-server/rs/process/definitions I got the error:
+15:55:08,229 WARNING [JDBCExceptionReporter] SQL Error: 23502, SQLState: 23502+
+15:55:08,229 SEVERE [JDBCExceptionReporter] NULL not allowed for column
"DIRTY"; SQL statement:+

values (null, ?, ?, ?, ?) [23502-158]+

+javax.persistence.PersistenceException:
org.hibernate.exception.ConstraintViolationException: could not insert:
[org.drools.persisten+
+ce.info.SessionInfo]+
Why suck a behavior?
I hope this can help someone of you :)
Regards,
Pierpaolo
