Hi, I have an ear application that runs under jboss 4.2.0.GA version. I have implemented EJB3 session bean. The AdSetSchedule Session Bean is bound as shown below in jndi view +- DPDS-Enterprise (class: org.jnp.interfaces.NamingContext) | | +- AdSetScheduleBean (class: org.jnp.interfaces.NamingContext) | | +- local (proxy: $Proxy99 implements interface com.dreamplay.dpds.ejb.AdSetScheduleLocal,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject) | | +- remote (proxy: $Proxy98 implements interface com.dreamplay.dpds.ejb.AdSetScheduleRemote The war application that uses JavaServer Faces calls the session bean like so. try { InitialContext ctx = new InitialContext(); System.out.println("Lookup AdSetScheduleBean"); Object o = ctx.lookup("DPDS-Enterprise/AdSetScheduleBean/local"); System.out.println("Done Lookup"); System.out.println("class name " + o.toString()); System.out.println("-----------"); com.dreamplay.dpds.ejb.AdSetScheduleLocal ad = (com.dreamplay.dpds.ejb.AdSetScheduleLocal) o; System.out.println("-----Done Lookup"); System.out.println("class name " + ad.toString()); } catch (NamingException e) { System.out.println("Naming Error occurred: " + e.toString()); } catch (ClassCastException e) { System.out.println("ClassCast Error occurred: " + e.toString()); } In my log I get the following error. 09:47:38,181 INFO [STDOUT] Lookup AdSetScheduleBean 09:47:38,181 INFO [STDOUT] Done Lookup 09:47:38,181 INFO [STDOUT] class name AdSetScheduleBean 09:47:38,181 INFO [STDOUT] ----------- 09:47:38,181 INFO [STDOUT] ClassCast Error occurred: java.lang.ClassCastException: $Proxy247 cannot be cast to com.dreamplay.dpds.ejb.AdSetScheduleLocal I tried casting the object like com.dreamplay.dpds.ejb.AdSetScheduleLocal ad = (com.dreamplay.dpds.ejb.AdSetScheduleBean)o; Even this gives me the error 10:04:21,506 INFO [STDOUT] ClassCast Error occurred: java.lang.ClassCastException: $Proxy247 cannot be cast to com.dreamplay.dpds.ejb.AdSetScheduleBean What am I doing wrong. Can anybody help. Thanks Masoodah View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140531#...
