Is it possible to deploy EJB2 style entity beans in a EJB 3.

[jeklund]

Hi everybody,

I'm about to try a phased migration from EJB2 to EJB3. When I changed version to <ejb-jar version="3.0" xmlns="http://java.sun.com/xml/ns/j2ee"> in ejb-jar.xml, JBoss lists every session bean as EJB3-service, but none of the old entity beans show up in the debug log.

However I get a lot of
"2007-08-28 09:00:30,558 WARN [org.jboss.injection.EJBHandler] IGNORING DEPENDENCY: unable to find <ejb-local-ref> of interface org.ejbca.core.ejb.ra.UserDataLocal and ejbLink of UserData in ejb-jar.xml of UserAdminSession it might not be deployed yet" warnings for the entity beans.

and later I get
"2007-08-28 09:00:31,271 DEBUG [org.jboss.ejb3.stateless.StatelessDelegateWrapper] Starting failed jboss.j2ee:ear=ejbca.ear,jar=ejbca-ejb.jar,name=TableProtectSession,service=EJB3
java.lang.RuntimeException: Failed to populate ENC: env/ejb/TableProtectDataLocal global jndi name was null"

I also noticed some
"2007-08-28 09:00:17,579 DEBUG [org.jboss.web.tomcat.service.TomcatDeployer] Unable to retrieve orbjavax.management.InstanceNotFoundException: jboss:service=CorbaORB is not registered." but I'm not sure this is related..

Isn't it possible to start the migration by simple running the old code in it's new environment? I'm using JBoss 4.2.1.GA and Sun's Java 1.5.0_12 on Ubuntu x64.

Any help would be greatly appreciated,
Johan

I guess http://www.jboss.com/index.html?module=bb&op=viewtopic&t=72369 answers my question (if it still is valid).

So.. I've split the project into two jar files project-ejb.jar and project-ejb-entities.jar that are deployed within an .ear.

The EJB version of project-ejb-entities.jar is 2.1. If the EJB version of project-ejb.jar is 2.1 too, everything works fine as before, but if I set the version of project-ejb.jar to 3.0 things start to go wrong..

using project-ejb-entities#bean-name in <ejb-link> elements I get the following

2007-08-29 15:07:48,261 WARN [org.jboss.ejb3.enc.DeploymentEjbResolver] can't find a deployment for path 'project-ejb-entities.jar' of ejb link 'project-ejb-entities.jar#TableProtectData'
2007-08-29 15:07:48,261 WARN [org.jboss.injection.EJBHandler] IGNORING DEPENDENCY: unable to find <ejb-local-ref> of interface org.ejbca.core.ejb.protect.TableProtectDataLocal and ejbLink of project-ejb-entities.jar#TableProtectData in ejb-jar.xml of TableProtectSession it might not be deployed yet

and without specifying the jar

2007-08-29 15:07:48,261 WARN [org.jboss.injection.EJBHandler] IGNORING DEPENDENCY: unable to find <ejb-local-ref> of interface org.ejbca.core.ejb.protect.TableProtectDataLocal and ejbLink of TableProtectData in ejb-jar.xml of TableProtectSession it might not be deployed yet

Using the same environment as before. Any help is greatly appreciated.
