Hi All,
I have created one small EJB application to learn EJB with JBoss. I have deployed the BookBean.jar file in the JBOS.
the foloowing message i get while starting the JBoss server.

11:47:30,609 INFO  [EJBDeployer] Deployed: file:/C:/JBOSS/jboss-4.0.2/jboss-4.0.2/server/default/deploy/book.jar
