Simple Question

Is it possible to use JBPM/JPDL in clustering mode?

[kukeltje]

depends on your definition of 'clustering mode', but jBPM can run on multiple servers sharing the same db schema in a shared database.

Using Yahoo with the words jBPM and clustering would have given you some hints

It certainly can. As Ronald states, synchronisation happens on the database. Check http://www.theserverside.com/tt/articles/article.tss?l=WorkflowEngineJBossCluster for example.
