Hi all,
After not being able to cope somehow with yesterday's problem about using OpenEJB as a remote server, i ran the same application, this time on OpenEJB used as an embedded engine. Here is what i get now: 1. Caused by: javax.transaction.TransactionRequiredException at org.apache.openejb.core.transaction.TxMandatory.<init>(TxMandatory.java:49) at org.apache.openejb.core.transaction.JtaTransactionPolicyFactory.createTransactionPolicy(JtaTransactionPolicyFactory.java:44) at org.apache.openejb.core.transaction.EjbTransactionUtil.createTransactionPolicy(EjbTransactionUtil.java:55) at org.apache.openejb.core.stateless.StatelessContainer._invoke(StatelessContainer.java:200)Error in statelessMandatoryTxAttribute at org.apache.openejb.core.stateless.StatelessContainer.invoke(StatelessContainer.java:169) at org.apache.openejb.core.ivm.EjbObjectProxyHandler.businessMethod(EjbObjectProxyHandler.java:217) at org.apache.openejb.core.ivm.EjbObjectProxyHandler._invoke(EjbObjectProxyHandler.java:77) at org.apache.openejb.core.ivm.BaseEjbProxyHandler.invoke(BaseEjbProxyHandler.java:286) ... 23 more (I am calling the MANDATORY bean from a REQUIRED one, so there has to be a transaction started.....) 2.

If you have the full, non-trimmed, stack trace that would help. Also
are you starting any threads anywhere in your bean code? -David On Jun 11, 2009, at 1:40 AM, recursion wrote: > > Hi all, > > After not being able to cope somehow with yesterday's problem about > using > OpenEJB as a remote server, i ran the same application, this time on > OpenEJB > used as an embedded engine.

No, in my bean code i do not start threads.
But i do start threads in my client code! There are approximately 10 threads, each one is performing its own lookup of my bean, and is invoking business methods. Could that be a problem ? |

Hard to say without knowing exactly where the client code is in the call chain. If it is getting executed anywhere downstream from an ejb call (say ejb->client->ejb) then it would cause the issue described. If not, then we'll definitely need the entire stack trace to have any idea of what may be happing. -David |

I got a similar excepion today, and figured out for the second time that it was because of this: ERROR - JAVA AGENT NOT INSTALLED. The JPA Persistence Provider requested installation of a ClassFileTransformer which requires a JavaAgent. See http://openejb.apache.org/3.0/javaagent.html and from the mentioned page it is clear that you have to add something like the following to your runtime VM args: -javaagent:openejb-javaagent-3.0-beta-2.jar |
