Using JBoss4.0.4 This is the first time I am trying to deploy a bean using EJB3.0/JPA. I get the following error. I'd appreciate any help me in getting me going with using JPA. java.lang.ClassCastException: $Proxy162 My Bean is annotated as: @Stateless | @RemoteBinding(jndiBinding="ABC/FMBean/remote") | public class FMABean implements FMALocal, FMARemote { | @PersistenceContext(unitName="FM") | protected EntityManager em ; | In the JSP I am trying to access the bean as: InitialContext ctx = new InitialContext(); | Object obj = ctx.lookup("ABC/FMAAdminBean/remote"); | System.out.println("obj class ="+obj.getClass()); | fmaAdmin = (FMAAdminBean) obj; JNDIView in JMX Console look like: | +- ABC (class: org.jnp.interfaces.NamingContext) | | +- FMABean (class: org.jnp.interfaces.NamingContext) | | | +- remote (proxy: $Proxy147 implements No ClassLoaders found for: com.boeing.begss.fm.FMARemote (no security manager: RMI class loader disabled)) | | +- FMAAdminBean (class: org.jnp.interfaces.NamingContext) | | | +- remote (proxy: $Proxy144 implements No ClassLoaders found for: com.boeing.begss.fm.FMAAdminRemote (no security manager: RMI class loader disabled)) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3974699#...
