[jboss-user] [JBoss jBPM] - Re: Problem running bpel process designed with eclipse bpel

I see two different problems. 
13:50:20,215 ERROR [XPathEvaluator] selection of size other than one: []
This means one of your expressions is required to return a node-set of size 1, as described in the BPEL spec, but it returned an empty node-set (as evidenced by the empty string inside the square brackets []). Check your expressions. The server log file (jboss-4.x.x/server/default/log/server.log) will tell you which expression was being evaluated and help you pinpoint the problem.
13:50:20,246 WARN  [loggerI18N] [com.arjuna.ats.internal.jta.transaction.arjunacore.lastResource.disallow] Adding multiple last resources is disallowed. Current resource is org.jboss.resource.connectionmanager.TxConnectionManager$LocalXAResource at 151cc3
This situation is known and documented. Please refer to section 3.5.2 "Transaction Manager" of the jBPM BPEL 1.1.1 manual for details.
