The issue is that I have a stateless EJB using CMT with the following problem:
a function X, having default transaction attribute (required) has a loop and
calls another function Y with a transaction attribute of REQUIRES_NEW. Function
Y does a SessionContext.setRollbackOnly. First itration calls Function Y, does
rollback and exits. Second iteration of loop, function Y is called and I get
the following; the error occurs during the getConnection() call in the
JBPMDao.removeEndedProcesses(pidVec) function (see below)
anonymous wrote : org.jboss.util.NestedSQLException: Transaction is not active:
tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=ro-0029aits/49, BranchQual=,
localId=49]; - nested throwable: (javax.resource.ResourceException: Transaction
