Using Spring's @Scheduled annotation I'm periodically calling a method to poll the queue and start new workflows running. The problem is because of the scheduling the method is called using another thread and the following error below occurs: {code} Caused by: java.lang.IllegalStateException: Unable to find transaction: java:comp/UserTransaction           at org.drools.persistence.jta.JtaTransactionManager.findUserTransaction(JtaTransactionManager.java:124) [drools-persistence-jpa-5.5.0.Final.jar:5.5.0.Final]           at org.drools.persistence.jta.JtaTransactionManager.<init>(JtaTransactionManager.java:69) [drools-persistence-jpa-5.5.0.Final.jar:5.5.0.Final]           at org.drools.persistence.SingleSessionCommandService.initTransactionManager(SingleSessionCommandService.java:303) [drools-persistence-jpa-5.5.0.Final.jar:5.5.0.Final]           at org.drools.persistence.SingleSessionCommandService.<init>(SingleSessionCommandService.java:117) [drools-persistence-jpa-5.5.0.Final.jar:5.5.0.Final]           ... 24 more Caused by: javax.naming.NameNotFoundException: java:comp/UserTransaction           at org.jboss.as.naming.InitialContext.lookup(InitialContext.java:121)           at org.jboss.as.naming.NamingContext.lookup(NamingContext.java:214)           at javax.naming.InitialContext.lookup(InitialContext.java:411) [rt.jar:1.7.0_10]           at org.drools.persistence.jta.JtaTransactionManager.findUserTransaction(JtaTransactionManager.java:119) [drools-persistence-jpa-5.5.0.Final.jar:5.5.0.Final]           ... 27 more {code} I'm using jbpm 5.4 and JBoss 7.1 I have read that using java:jboss/TransactionManager instead can resolve this issue but java:comp/UserTransaction is hard coded in the drools-persistence-jpa jar. Do I need to download the source and build another version of the jar? There must be a simple work around for this. Thanks in advance.
