But even if it does, you could always use the in-memory hsqldb. No 'real' persistence then. Thanks! This is probably a dumb question, but where are the testcases you are referring to? Does JBPM ship with its own JUnit tests? If so, where are they located? Also, just a clarification about persistence.
