[JNDI and Naming] - Unable to override JNDI name for session bean
by keigwin
I'm using JBossAS 5.1.0 and have just upgraded the Eclipse projects for an existing application to support EJB3. I then converted one of the session beans in the app to an EJB3-style declaration. I've been able to successfully call this bean if I use JBoss' default JNDI name for the bean.
Now I need to override the JNDI name and have had no luck doing this. The mappedName attribute in the @Stateless annotation seems to have no effect on the name the bean is bound to. For example, with the bean declared this way:
@Stateless(mappedName="com.sellcore.service.GeographyService")
| public class GeographyService implements GeographyServiceLocal
| {
the JBoss management console shows it is still bound to the default name:
+- UnitTestsEAR (class: org.jnp.interfaces.NamingContext)
| | +- GeographyService (class: org.jnp.interfaces.NamingContext)
| | | +- local-com.sellcore.facade.common.GeographyServiceLocal (class: Proxy for: com.sellcore.facade.common.GeographyServiceLocal)
| | | +- local (class: Proxy for: com.sellcore.facade.common.GeographyServiceLocal)
where UnitTestsEAR is the EAR containing the bean and its client WAR.
The appserver logs show that the new name is found by JBoss:
15:12:13,249 INFO [JBossASKernel] Added bean(jboss.j2ee:ear=UnitTestsEAR.ear,jar=SellCoreService.jar,name=PrintApplication,service=EJB3) to KernelDeployment of: SellCoreService.jar

| 15:12:13,249 INFO [JBossASKernel] Class:com.sellcore.facade.common.GeographyServiceLocal
But the value I specified as the mappedName is not used at binding time, as shown later in the log:
15:12:13,937 INFO [SessionSpecContainer] Starting jboss.j2ee:ear=UnitTestsEAR.ear,jar=SellCoreService.jar,name=GeographyService,service=EJB3

|
| UnitTestsEAR/GeographyService/local - EJB3.x Default Local Business Interface
| UnitTestsEAR/GeographyService/local-com.sellcore.facade.common.GeographyServiceLocal - EJB3.x Local Business Interface
I know I'm probably doing something really ignorant, but I can't figure out what. I'd really appreciate any assistance!
Thanks,
K-

[EJB 3.0 Users] - Getting the ejbName inside an interceptor
by pete.muir＠jboss.org
This is for JBoss EJB 3 integration code, so we can use JBoss interfaces, not just EJB standard interfaces.
Inside an interceptor instance, I need access to the ejbName of the EJB being intercepted (so I can use this as a unique key to look up other info on the EJB). Currently I am doing this ugly hack:
try {
| guidField = StatefulSessionContextImpl.class.getDeclaredField("containerGuid");
| guidField.setAccessible(true);
| } catch (Exception e) {
| throw new RuntimeException(e);
| }
|
| ...
|
| try {
| String guid = (String) guidField.get(sessionContext);
| Container container = Ejb3Registry.getContainer(guid);
| return container.getEjbName();
| } catch (Exception e) {
| throw new RuntimeException(e);
| }
Any suggestions on how to improve?

[JBoss Portal Users] - Re: Role based landing page/portal for user
by pathuri
Hi vivek_saini07,
I wish I had known this issue 4 months ago to ask for help :-) We are new to portal and are working our way thru.
We are on to building a large CRM based application using JBoss Portal and came across this issue only few days ago.
Thanks a lot for the lead. I think these details are valuable and we will see if we can make the necessary changes and make it to work.
Thanks again.

| Had you asked me it four months back, I would have told u this in more detail as I had lots of time (and energy) at that time.
|
| In short, we did it by modifying customizationManagerService. There are number of threads in this forum explaining how to do this.
|
| In that class somewhere it is written that a portal named "Template" would always be copied to dashboard of logged in user.
|
| U can change that piece, some conditional tweak........... on certain condition copy this portal ....otherwise copy some other portal.
|
| We maintained a table in DB that had mapping between users and their portal.
|
| And after doing all this, there is a property in property file of "conf" folder (this is documented in reference guide) by setting that property user will always land to his dashboard after log-in instead of (public)portal.
|
| Hope this would help.

[EJB] - Accessing EJB 2.1 in a isolated EARs
by gjeudy
Hi,
I'm trying to access EJBs in isolated EARs in JBoss 4.2.2.GA in the same server instance. Is it possible to only enable Call by Value semantics for 1 EJB and not for all EJBs deployed in an EAR?
I tried countless combinations and the only one that seemed to work is the below:
I have EJBA in ear1 access EJBB in ear2 both are isolated using loader-repository in their jboss-app.xml:
| <jboss-app>
| <loader-repository>loader=ear1</loader-repository>
| </jboss-app>
|
| <jboss-app>
| <loader-repository>loader=ear2</loader-repository>
| </jboss-app>
|
enable call by value in the ear-deployer.xml:
| <attribute name="CallByValue">true</attribute>
|
EJBA code to access EJBB:
| Context testcontext = new InitialContext();
| EJBBHome objref = (EJBBHome)testcontext.lookup("jnp://localhost:1299/ejb/EJBB");
| log.info("Looked up ejbb:" + objref);
| objref.create().doSomething();
|
The call succeeds but as soon as I set CallByValue=false, I get:
| 2009-08-27 15:25:00,401 ERROR [org.jboss.ejb.plugins.LogInterceptor] TransactionRolledbackException in method: public abstract testearisolation.ear2.EJBB testearisolation.ear2.EJBBHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException, causedBy:
| javax.ejb.EJBException: Invalid invocation, check your deployment packaging, method=public abstract testearisolation.ear2.EJBB testearisolation.ear2.EJBBHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException
|
I could use my working solution but then if I understand correctly it means all EJBs for all EARs under this server instance will use Call By Value semantics regardless if its 2 EJBs talking to each other in the same EAR...
Please correct me if im wrong.
Thanks
-Guillaume
