thats a configuration issue. configure history-service and history-session as in jbpm4/trunk/modules/test-db/src/main/test/resources/jbpm.cfg.xml View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4210966#4210966 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4210966

[Design of JBoss jBPM] - statefull vs stateless delegation classes

by tom.baeyens＠jboss.com

can we safely assume that all delegation classes are stateless ? when a process calls out to a user class, this can be done by specifying the classname and some configuration injections. there are various use cases of delegation classes: Assigner's (aka AssignmentHandlers), EventListeners (aka Actions) and so on. with delegation classes being stateless i mean that execution of those delegation classes will not update their member field. so after construction (incl injecting configuration) they can be considered immutable. if that is the case, those objects become thread safe and cacheble. we didn't assume this in jbpm 3 and hence instantiated each object each time as there is no good way of introducing caching. so... can we safely assume that all delegation classes are stateless as the default ?

you'll still find that execution in the history. see HistoryService. runtime execution tables need to be kept clean to keep the runtime system healthy.

[Design of JBoss jBPM] - Re: deletion problem

by galanfish

oh... it's my mistake... i wrongfully set hibernate.dialect=org.hibernate.dialect.MySQLDialect and i fixed it as hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect, then the testcase runned well... by the way, is that a execution would be set state to 'ended' when it is finished? and the pvm will delete the record from the table 'jbpm_execution'? can i cancel this? i mean when the execution finished, can i keep the record in database just update the state to 'ended'?

[Design of JBoss jBPM] - Re: process definition as a resource

by camunda

Technically I think yes. But for the development this would be a nightmare I think (renaming the stuff yourself, keep track what has changed to not forget to rename something and so on). And it could be that your new version requires a different third party library version, which is easily possible with scoped deployment, but not without (or do I forget something here?)....
