[JBoss7] call-by-value and call-by-reference

swoeste Feb 22, 2012 5:27 AM

Hi Guys,

I’m currently migrating some of our applications from JBoss4 to JBoss7 and have a question about the transaction of beans.

In JBoss4 we had to set the bean transaction to 'call-by-value'.

How is this managed in JBoss7 ? - I can’t find any doc about that topic.

best regards

Sebastian

Call by value for "transactions"? Or do you mean call by value semantics for invocation on remote interfaces of a bean?

Sry, my fault.
Yes, i meant the invocation on remote interfaces of a bean.

The EJB spec mandates that calls to remote interfaces on EJB, use call-by-value semantics. AS7 however allows you to configure call-by-reference semantics for invocations on remote interfaces of EJB, in the same VM. You can configure it at each application level (via jboss-ejb-client.xml) or for all applications on the server at the EJB3 subsystem level. See this JIRA for details https://issues.jboss.org/browse/AS7-3330
