[jboss-user] [jBPM] - Using multiple kSessions

Richard Evans [https://community.jboss.org/people/r3vans] created the discussion "Using multiple kSessions" To view the discussion, visit: https://community.jboss.org/message/744551#744551 -------------------------------------------------------------- I have not been able to get multiple sessions working properly: * I declare multiple sessions in the spring context (see below). * I start a pool of threads. As each thread is executed I grab session and save it in a ThreadLocal. * I despatch calls to kSession.startProcess in each thread. Is this a reasonable approach? I find that this will run OK for a while but ultimately will fail either with an NPE in ProcessInstanceImpl getProcess because kruntime is null OR will fail to commit a transaction because it has already been committed.
