"Startup problem cause java.lang.ClassNotFoundException: org.drools.persistence.processinstance.WorkItemInfo" To view the discussion, visit: http://community.jboss.org/message/620799#620799 -------------------------------------------------------------- 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.
