It fails though it connects from a single Java program with the JBossAS7.1.1 server by using Remote EJB Client, and it tries to acquire UserTransaction.
However, it is attached from the beginning with the sample, and 'Jms/queue/test' can do lookup correctly.

Result(It operates correctly. )

Source JNDI = java:jboss/UserTransaction

jboss.naming.context.java.jboss.exported.jboss.UserTransaction

The cause of javax.naming.NameNotFoundException is not understood well.

It is What 'jboss.naming.context.java.jboss.exported' ?
