[JBoss-user] [EJB/JBoss] - Re: After redeployment jndi lookup gets ClassCastException
Hi, I too am experiencing this very same problem on 3.0.6 but I do need to make a remote call so its not an option for me to comment out the jndi url line. Does anyone know why this is occurring and whether or not there is a workaround? Regards Lea.

Yes the scheduler.sar ejb.jar are in the same ear. Also I tried to separate scheduler into single deployed file -- but same result...

It looks that my enemy is class-loader so I've added into jboss-app.xml following: loader-repositorydummy:loader=dummy.ear/loader-repository However it does not solving the redeployment issue at all...

[JBoss-user] [EJB/JBoss] - Re: After redeployment jndi lookup gets ClassCastException
hrm - i'm not really sure. you shouldn't be getting casting exceptions if both archives are being deployed as one unit. the classloader that deploys the ear should be the same one that is being used to look up class references. i haven't experienced this problem when deploying everything in one ear. adding the loader repository isn't going to do you much good in this instance b/c you're not trying to prevent the classes inside the ear from being accessed outside of the ear. assuming you have a mbean in the sar, is it being shutdown and destroyed properly on the hot-deployment? the only other thing that comes to mind is that somehow it's not being completely destoryed and somehow as an incorrect reference. at this point, i'd recommend turing on classloader debugging and posting back the relevant portions here.

Thanks for your time to help on this issue. DummyService MBEAN implements schedulable interface and calls the Worker session bean. As I said in my original post, this works fine if you restart the jboss appserver. Here is the jboss log and you can see that dummyService MBEAN actually gets unloaded when redeployment occurs -- very strange indeed... 16:08:41,812 INFO [EjbModule] Stopping jboss.j2ee:module=ejb_test.jar,service=E jbModule 16:08:41,843 INFO [StatelessSessionContainer] Stopping jboss.j2ee:jndiName=dumm y/fileFetcherHome,service=EJB 16:08:41,843 INFO [StatelessSessionInstancePool] Stopping jboss.j2ee:jndiName=d ummy/fileFetcherHome,plugin=pool,service=EJB 16:08:41,859 INFO [Scheduler] Stopping dummy:service=dummyService 16:08:41,859 INFO [StatelessSessionContainer] Stopping jboss.j2ee:jndiName=work erHome,service=EJB 16:08:41,859 INFO [StatelessSessionInstancePool] Stopping jboss.j2ee:jndiName=w orkerHome,plugin=pool,service=EJB 16:08:41,859 INFO [StatelessSessionContainer] Stopping jboss.j2ee:jndiName=dumm yManager,service=EJB 16:08:41,859 INFO [StatelessSessionInstancePool] Stopping jboss.j2ee:jndiName=d ummyManager,plugin=pool,service=EJB 16:08:41,859 INFO [EntityContainer] Stopping jboss.j2ee:jndiName=dummyLocalHome ,service=EJB 16:08:41,875 INFO [EntityInstancePool] Stopping jboss.j2ee:jndiName=dummyLocalH ome,plugin=pool,service=EJB 16:08:41,875 INFO [TxConnectionManager] Stopping jboss.jca:service=LocalTxCM,na me=datasource/dummy 16:08:41,875 INFO [JBossManagedConnectionPool] Stopping jboss.jca:service=Manag edConnectionPool,name=datasource/dummy 16:08:41,875 INFO [RARDeployment] Stopping jboss.jca:service=ManagedConnectionF actory,name=datasource/dummy 16:08:41,875 INFO [EARDeployer] Undeploying J2EE application, destroy step: fil e:/C:/temp/local/jboss-3.2.2/server/default/deploy/dummy.ear 16:08:41,906 INFO [EJBModule] destroy(), remove EJB-Module: jboss.management.lo cal:J2EEApplication=dummy.ear,J2EEServer=Local,j2eeType=EJBModule,name=ejb_test. jar 16:08:41,953 WARN [DeploymentInfo] Could not delete file:/C:/temp/local/jboss-3 .2.2/server/default/tmp/deploy/tmp42655dummy.ear restart will delete it 16:08:42,000 INFO [MainDeployer] Starting deployment of package: file:/C:/temp/ local/jboss-3.2.2/server/default/deploy/dummy.ear 16:08:42,015 INFO [EARDeployer] Init J2EE application: file:/C:/temp/local/jbos s-3.2.2/server/default/deploy/dummy.ear 16:08:42,671 INFO [EJBDeployer] nested deployment: file:/C:/temp/local/jboss-3. 2.2/server/default/tmp/deploy/tmp42656dummy.ear-contents/ejb_test.jar-contents/M ETA-INF/mysql-ds.xml 16:08:46,453 INFO [EjbModule] Deploying DummyEJB 16:08:46,484 INFO [EjbModule] Deploying DummyManager 16:08:46,500 INFO [EjbModule] Deploying Worker 16:08:46,531 INFO [EjbModule] Deploying FileFetcher 16:08:46,765 INFO [RARDeployment] Started jboss.jca:service=ManagedConnectionFa ctory,name=datasource/dummy 16:08:46,765 INFO [JBossManagedConnectionPool] Started jboss.jca:service=Manage dConnectionPool,name=datasource/dummy 16:08:46,765 INFO [datasource/dummy] Bound connection factory for resource adap ter for ConnectionManager 'jboss.jca:service=LocalTxCM,name=datasource/dummy to JNDI name 'java:/datasource/dummy' 16:08:46,765 INFO [TxConnectionManager] Started jboss.jca:service=LocalTxCM,nam e=datasource/dummy 16:08:47,281 INFO [DummyEJB] Table 'Test' already exists 16:08:47,281 INFO [EntityInstancePool] Started jboss.j2ee:jndiName=dummyLocalHo me,plugin=pool,service=EJB 16:08:47,296 INFO [EntityContainer] Started jboss.j2ee:jndiName=dummyLocalHome, service=EJB 16:08:47,359 INFO [StatelessSessionInstancePool] Started jboss.j2ee:jndiName=du mmyManager,plugin=pool,service=EJB 16:08:47,359 INFO [StatelessSessionContainer] Started jboss.j2ee:jndiName=dummy Manager,service=EJB 16:08:47,406 INFO [StatelessSessionInstancePool] Started jboss.j2ee:jndiName=wo rkerHome,plugin=pool,service=EJB 16:08:47,406 INFO [StatelessSessionContainer] Started jboss.j2ee:jndiName=worke rHome,service=EJB 16:08:47,406 INFO [STDOUT] DummyService has been initialized() 16:08:47,421 INFO [Scheduler] Started dummy:service=dummyService 16:08:47,421 INFO [StatelessSessionInstancePool] Started jboss.j2ee:jndiName=du mmy/fileFetcherHome,plugin=pool,service=EJB 16:08:47,421 INFO [StatelessSessionContainer] Started jboss.j2ee:jndiName=dummy /fileFetcherHome,service=EJB 16:08:47,421 INFO [EjbModule] Started jboss.j2ee:module=ejb_test.jar,service=Ej bModule 16:08:47,421 INFO [EJBDeployer] Deployed: file:/C:/temp/local/jboss-3.2.2/serve r/default/tmp/deploy/tmp42656dummy.ear-contents/ejb_test.jar 16:08:47,531 INFO [EARDeployer] Started J2EE application: file:/C:/temp/local/j boss-3.2.2/server/default/deploy/dummy.ear 16:08:47,531 INFO [MainDeployer] Deployed package: file:/C:/temp/local/jboss-3. 2.2/server/default/deploy/dummy.ear 16:08:48,453 INFO [STDOUT] DummyService dummyTest() invoked... 16:08:48,484 INFO [STDOUT] $Proxy30 16:08:48,484 ERROR

turn on classloader debugging (insert the following into your log4j.xml file)
| appender name=UCL class=org.apache.log4j.FileAppender
| param name=File value=${jboss.server.home.dir}/log/ucl.log/
| param name=Append value=false/
| layout class=org.apache.log4j.PatternLayout
| param name=ConversionPattern value=[%r,%c{1},%t] %m%n/
| /layout
| /appender
| category name=org.jboss.mx.loading additivity=false
| priority value=TRACE class=org.jboss.logging.XLevel/
| appender-ref ref=UCL/
| /category
|
if you have the jboss admin book, this is talked about in chapter 2 and it explains
how to use the jmx console to provide some additional information (not sure if any of
this is on a wiki page or not).
