Some new information to help in the diagnosis of this problem: I've discovered that the same problem occurs when a working JAR is deleted and re-deployed (using Ant) with the EXACT SAME JAR! I noticed that prior to deleting the JAR, the deployed TravelAgentBean (the session bean for which the error message is complaining of "Wrong target") in the JNDIView shows the following: | +- remote (proxy: $Proxy92 implements interface com.titan.travelagent.TravelAgentRemote,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBObject) After deleting and redeploying, the proxy value changes to a different number: Thank you. I really appreciate any moments you could spend helping me on this. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977407#...
