Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: JD Brennan (jazzdevotee) Assigned to: Nobody/Anonymous (nobody) Summary: ClassCastException after redeploy Initial Comment: Linux (2.2 kernel) JDK 1.4 ========================================= ======================================= JBoss Bootstrap Environment JBOSS_HOME: /opt/jboss-3.0.0 JAVA: /opt/j2sdk1.4.0/bin/java JAVA_OPTS: -server -Dprogram.name=run.sh CLASSPATH: /opt/jboss- 3.0.0/bin/run.jar:/opt/j2sdk1.4.0/lib/tools.jar ========================================= ======================================= 15:15:05,459 INFO [Server] JBoss Release: JBoss- 3.0.0 CVSTag=JBoss_3_0_0 Steps: 1) call a bean that serializes object X that implements interface Y somewhere (I store it in a mysql database). 2) call a bean that deserializes the object and casts it to the interface Y. 3) redeploy the ejb jar file that contains the bean (hot redeploy. Don't restart JBoss. 4) repeat step 2 Excepted: Same result as Step 2 Actual: ClassCastException ---------------------------------------------------------------------- Comment By: Steve Harvey (sgharvey) Date: 2002-08-12 03:09 Message: Logged In: YES user_id=593359 Fixed in 3.0.1? I had the same problem, with a SLSB trying to cast the result of a JNDI lookup into an EB home type, throwing CCE after redeployment. I added reflection code to the SLSB to examine the class loader delegation chain for both the IF class and looked up object. The IF class CL was a UnifiedClassLoader instance with its originating jar as repository, but the looked up object had a copy of jnpserver.jar as the repository for its UCL instance. Upon redeployment, only the IF class CL got a new UCL instance. Upon switching to the IBM 1.3 JDK from Sun's 1.4, I witnessed the same behaviour, minus the CCE being thrown. Then I noticed that JBoss-3.0.1 was out and tried it and the problem went totally away, no CCE, and both CL instances identical. This was all on Linux 2.2 . ---------------------------------------------------------------------- Comment By: Kenny Smith (subsstuff1) Date: 2002-06-04 18:07 Message: Logged In: YES user_id=548391 hell no spoke to soon - problem still exists, disguised as a different exception: ---- 00:03:26,130 ERROR [STDERR] java.lang.ClassCastException 00:03:26,130 ERROR [STDERR] at com.sun.corba.se.internal.javax.rmi.PortableR emoteObject.narrow(PortableRemoteObject.java:293) 00:03:26,140 ERROR [STDERR] at javax.rmi.PortableRemoteObject.narrow(Portabl eRemoteObject.java:134) 00:03:26,150 ERROR [STDERR] at com.foo.account.AccountUtil.getHome(Unknown Source) 00:03:26,160 ERROR [STDERR] at com.foo.account.AccountRegistryBean.createAccount (Unknown Source) 00:03:26,170 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke0( Native Method) 00:03:26,180 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke(N ativeMethodAccessorImpl.java:39) 00:03:26,190 ERROR [STDERR] at sun.reflect.DelegatingMethodAccessorImpl.invo ke(DelegatingMethodAccessorImpl.java:25) 00:03:26,200 ERROR [STDERR] at java.lang.reflect.Method.invoke(Method.java:3 24) 00:03:26,210 ERROR [STDERR] at org.jboss.ejb.StatelessSessionContainer$Conta inerInterceptor.invoke(StatelessSessionContainer.java:664) 00:03:26,220 ERROR [STDERR] at org.jboss.resource.connectionmanager.CachedCo nnectionInterceptor.invoke (CachedConnectionInterceptor.java:186) 00:03:26,230 ERROR [STDERR] at org.jboss.ejb.plugins.StatelessSessionInstanc eInterceptor.invoke (StatelessSessionInstanceInterceptor.java:77) 00:03:26,240 ERROR [STDERR] at org.jboss.ejb.plugins.AbstractTxInterceptor.i nvokeNext(AbstractTxInterceptor.java:96) 00:03:26,250 ERROR [STDERR] at org.jboss.ejb.plugins.TxInterceptorCMT.runWit hTransactions(TxInterceptorCMT.java:167) 00:03:26,260 ERROR [STDERR] at org.jboss.ejb.plugins.TxInterceptorCMT.invoke (TxInterceptorCMT.java:61) 00:03:26,270 ERROR [STDERR] at org.jboss.ejb.plugins.SecurityInterceptor.inv oke(SecurityInterceptor.java:129) 00:03:26,280 ERROR [STDERR] at org.jboss.ejb.plugins.LogInterceptor.invoke(L ogInterceptor.java:166) 00:03:26,300 ERROR [STDERR] at org.jboss.ejb.StatelessSessionContainer.invok e(StatelessSessionContainer.java:313) 00:03:26,310 ERROR [STDERR] at org.jboss.ejb.Container.invoke(Container.java :705) 00:03:26,320 ERROR [STDERR] at org.jboss.mx.server.MBeanServerImpl.invoke(MB eanServerImpl.java:491) 00:03:26,330 ERROR [STDERR] at org.jboss.invocation.jrmp.server.JRMPInvoker. invoke(JRMPInvoker.java:362) 00:03:26,340 ERROR [STDERR] at sun.reflect.GeneratedMethodAccessor30.invoke( Unknown Source) 00:03:26,350 ERROR [STDERR] at sun.reflect.DelegatingMethodAccessorImpl.invo ke(DelegatingMethodAccessorImpl.java:25) 00:03:26,360 ERROR [STDERR] at java.lang.reflect.Method.invoke(Method.java:3 24) 00:03:26,370 ERROR [STDERR] at sun.rmi.server.UnicastServerRef.dispatch(Unic astServerRef.java:261) 00:03:26,380 ERROR [STDERR] at sun.rmi.transport.Transport$1.run(Transport.j ava:148) 00:03:26,390 ERROR [STDERR] at java.security.AccessController.doPrivileged(N ative Method) 00:03:26,390 ERROR [STDERR] at sun.rmi.transport.Transport.serviceCall(Trans port.java:144) 00:03:26,400 ERROR [STDERR] at sun.rmi.transport.tcp.TCPTransport.handleMess ages(TCPTransport.java:460) 00:03:26,410 ERROR [STDERR] at sun.rmi.transport.tcp.TCPTransport$Connection Handler.run(TCPTransport.java:701) 00:03:26,440 ERROR [STDERR] at java.lang.Thread.run (Thread.java:536) ---------------------------------------------------------------------- Comment By: Kenny Smith (subsstuff1) Date: 2002-06-04 17:34 Message: Logged In: YES user_id=548391 just installed JBoss 3.0.0 (2002.05.31) - problem gone ---------------------------------------------------------------------- Comment By: Bob Cotton (bcotton969) Date: 2002-06-04 12:07 Message: Logged In: YES user_id=424902 I'm seeing this too.

Therefore it can be a VM-bug, or jboss using the VM in a wrong way. I think this is the same bug as my #562972. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=563120&group_id=22866 ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development
