[jboss-user] [jBPM Users] - WebLogic 10 : couldn't lookup 'UserTransaction' from jndi

[dtoch]

I'm trying to use JBPM 4.2 in WebLogic 10, but I get:

org.jbpm.api.JbpmException: couldn't lookup 'UserTransaction' from jndi: Unable to resolve 'UserTransaction'. Resolved '': Unable to resolve 'UserTransaction'. Resolved ''
	at org.jbpm.pvm.internal.tx.jta.JtaTransaction.lookupFromJndi(JtaTransaction.java:137)

	at org.jbpm.pvm.internal.cfg.ProcessEngineImpl.buildProcessEngine(ProcessEngineImpl.java:170)

In WebLogic the JNDI name is javax.transaction.UserTransaction, not UserTransaction. Apparently org.jbpm.pvm.internal.tx.jta.JtaTransaction contains a protected member userTransactionJndiName in order to pass another JNDI name then the default one which is for JBoss, but I'm not sure what's the correct/elegant way to override it. Should I use the JBPM Environment API for this, or should I customize the JBPM XML configurations?
