Hi jaikiran, In MyEclipse I created a EJB project , name it FirstEJB, the three java files of bean are under src\com directory, and the client code are under src\test directory, then I ceated a folder lib under FirstEJB and copy the jbossall-client.jar to lib folder, then through the properties of the FirstEJB project, I add the lib\jbossall-client.jar to the java Build Path Libraries, that's it. After finishing the above steps, my EJB project looks like the following: FirstEJB |---src | |--com | | |---HelloEJB.java | | |---HelloEJBLocal.java | | |---HelloEJBRemote.java | |---test | | |---TestHelloEJB.java | |---META-INF |---JRE System Library[jdk6] |---Java EE 5 Libraries |---jbossall-client.jar |---lib Please note that, jbossall-client.jar is actually pasted into the lib directory,, but after I set the \lib\jbossall-client.jar to the java build path, jbossall-client.jar file appears above the lib directory. If I set the JBOSS_HOME\client\jbossall-client.jar to the project's build path, everything goes well. The project structure will change a little, like the following: FirstEJB |---src | |--com | | |---HelloEJB.java | | |---HelloEJBLocal.java | | |---HelloEJBRemote.java | |---test | | |---TestHelloEJB.java | |---META-INF |---JRE System Library[jdk6] |---Java EE 5 Libraries |---jbossall-client.jar - D:\jboss-5.0.1.GA\client\ In this case, the jbossall-client.jar is the one under the server's client directory View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4221778#...
