[JBoss-user] [Installation Configuration] - Re: loader repository problem
The call-by-value element was not being read correctly. This is simply a shortcut for specifying the call by value invoker interceptor stack. This example from the testsuite shows the custom call-by-value-jrmp invoker-proxy-binding that serializes calls between components: | ?xml version=1.0 encoding=UTF-8? | | jboss |enterprise-beans | session | ejb-nameCalleeSessionBean/ejb-name | jndi-nameejbcts2/CalleeSessionHome/jndi-name | invoker-bindings | invoker | invoker-proxy-binding-namecall-by-value-jrmp/invoker-proxy-binding-name | /invoker | /invoker-bindings | /session |/enterprise-beans | |invoker-proxy-bindings | invoker-proxy-binding | namecall-by-value-jrmp/name | invoker-mbeanjboss:service=invoker,type=jrmp/invoker-mbean | proxy-factoryorg.jboss.proxy.ejb.ProxyFactory/proxy-factory | proxy-factory-config |client-interceptors | home | interceptororg.jboss.proxy.ejb.HomeInterceptor/interceptor | interceptororg.jboss.proxy.SecurityInterceptor/interceptor | interceptororg.jboss.proxy.TransactionInterceptor/interceptor | interceptororg.jboss.invocation.ByValueInvokerInterceptor/interceptor | /home | bean | interceptororg.jboss.proxy.ejb.StatelessSessionInterceptor/interceptor | interceptororg.jboss.proxy.SecurityInterceptor/interceptor | interceptororg.jboss.proxy.TransactionInterceptor/interceptor | interceptororg.jboss.invocation.ByValueInvokerInterceptor/interceptor | /bean |/client-interceptors | /proxy-factory-config | /invoker-proxy-binding |/invoker-proxy-bindings | | /jboss | | View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3842904#3842904 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3842904 --- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!

[JBoss-user] [Installation Configuration] - Re: loader repository problem
Thanks a lot for your support. Meanwhile I figured out the reason for the exception: there was a j2ee.jar somewhere within a subdirectory of my ejb-archive. I thought that jboss would only grap jar files located at the root level directory of a jar or ear... Isolating deployments from one another works well now. Thanks as well for the artical you posted. Yes, I have the need to let several isolated deployments talk to one another. I tested the approach from the artical and it worked, however, I'm not satisfied with the approach proposed there. I would have thought that one could achieve the same with the following packaging structure for the scenario of invoking an EJB in scoped ear A from within a scoped ear B: scoped ear A Implementation class of EJB ONE Interface classes of EJB ONE scoped ear B other EJBs, Wars.. Interface classes of EJB ONE However this doesn work. I also tried setting the call-by-value field to true within the EJB jar but it still didn't work. Even with the approach mentioned in the artical, I wonder how this sort of bean communication works in clustered environments? Isn't there a way to configure JBoss to handle Bean invocations without needing to instantiate classes for his own use? The only classes to be shares by applications are the interface classes. If Jboss created Dynamic Proxy classes for all ejb interface classes for all ejbs referenced from ejb-ref or ejb-local ref elements within a scoped ear and then let these proxy classes speak to the bean proxy class registered within the JNDI context, it should be possible to completely prevent classloading issues because the JBoss proxy classes could be made to communicate with another using a loosely coupled serialization mechanism - at least as a special case for cross communication between isolated deployment units. If this cannot be made to work, we would have to switch towards XML communication between different deployment units, but it would be much nicer if this could be done transparently.

[JBoss-user] [Installation Configuration] - Re: loader repository problem
well, the warning about only the root deployer being allowed to set the loader-repository goes away, but the error remains. Stack trace looks the same to me, here are the first lines: 2004-07-15 12:41:41,498 INFO [org.jboss.deployment.EARDeployer] Init J2EE application: file:/blabla/jboss325/server/default/deploy/apps/test3.ear/ 2004-07-15 12:41:41,998 INFO [org.jboss.ejb.EjbModule] Deploying Test 2004-07-15 12:41:42,217 ERROR [org.jboss.ejb.StatelessSessionContainer] Initialization failed jboss.j2ee:jndiName=java%3aejb/Test,service=EJB java.lang.ClassCastException at org.jboss.ejb.plugins.local.BaseLocalProxyFactory.getEJBLocalHome(BaseLocalProxyFactory.java:210) at org.jboss.ejb.Container.createService(Container.java:581) at org.jboss.ejb.StatelessSessionContainer.createService(StatelessSessionContainer.java:133) at org.jboss.system.ServiceMBeanSupport.jbossInternalCreate(ServiceMBeanSupport.java:237) Let me also mention the following: - if the EAR only contains a war archive and the bean is its own top-level deployment unit, setting a loader-repository within the EAR does not cause the error. However, I would like to have EARs containing EJBs and having their own loader-rep. - on the one hand, what I understand from the (purchased) jboss documentation is that setting the loader-rep within the jboss-app descriptor sets this loader for all subcomponents within this ear. On the other hand the jboss-web and jboss descriptors also allow for the specification of a loader-rep, so I tried to play around with this feature as well. - when I download jboss3.2.5, extract it and start it without having made any modification to it, it would also give me a warning about only root deployers being allowed to set a loader-rep: 2004-07-15 12:47:29,643 INFO [org.apache.catalina.startup.Catalina] Server startup in 110 ms 2004-07-15 12:47:29,768 WARN [org.jboss.deployment.DeploymentInfo] Only the root deployment can set the loader repository, ingoring config=null 2004-07-15 12:47:29,783 INFO [org.jboss.web.tomcat.tc5.TomcatDeployer] deploy, ctxPath=/invoker, warUrl=file:/blabla/jboss325/server/default/deploy/management/http-invoker.sar/invoker.war/ - I'm no novice to J2EE. The company I'm working for is using Jboss to run several EARs covering all of J2EE: JMS, JCA, JDBC, all EJB types etc. Now I'm trying to investigate four features that are becoming more and more crucial to us: - we need to be able to isolate the EARs from one another - we need to be able to specify alternative deployment descriptors within the application.ear archive - we need to be able to reload an EJB without having to reload all other deployment units that depend on it. - we would like to be able to deploy several different ejb-implementation-classes for the same ejb-home and ejb-object interface However, I can get NONE of the above usecases to work. No matter how hard or how long I try. I know that the JBoss group offers commercial support. What my team needs whout be to submit detailed descriptions of the above use-cases to a JBoss support agent and get back one simple hello-world example application per use-case, showcasing that the JBoss server is actually capable of fullfilling the specified requirements of the respective use-case.

you should definately read this wiki page: http://www.jboss.org/wiki/Wiki.jsp?page=HotDeployClassCastExceptions some of the information contained w/in will be relevant to you. can you send me the ear you're working w/ (jgangemi at yahoo dot com) and i'll take a look at it locally. also, are you planning on having any of these isolated ears communicate w/ each other?

[JBoss-user] [Installation Configuration] - Re: loader repository problem
look at the error message that was thrown w/ the exception. you only define the loader-repository tag inside the jboss-app.xml file. you need to remove that entry from the jboss.xml file that is packaged w/ your ejb.

[JBoss-user] [Installation Configuration] - Re: loader repository problem
thanks for your reply, but I tried this as well and it doesn't work either. If I leave the jboss file out nothing changes. that is what is puzzling me so hard. I've created the smallest possible application which runs perfectly and just by adding the loader-repository fragment to the jboss-app.xml I can make it crash during deployment.

[JBoss-user] [Installation Configuration] - Re: loader repository problem
what is the new error that you get? if you removed the jboss.xml file and you aren't duplicating the load-repository definition anywhere else, i would think you'd also be getting a new error.
