Migrating EJB3 Code from 4.2 to 5.0 and encountering [JBMET

[jriley]

I have developed a working EJB3 application in 4.2.2. When I try the applciation in 5.0.0 GA I get a annotation validation exception when loading the Session bean.

I have created a very simple example and get the same problem. Can anyone explain what I am doing wrong.

The interfaces EchoServiceRemote and EchoServiceLocal extend the same EchoService interface where the one method is defined.

package com.echo;

import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;


@Stateless( name="ejb/Echo")
@Remote( EchoServiceRemote.class )
@Local( EchoServiceLocal.class )
public class EchoServiceBean implements EchoService{


 public String echo( String msg ) {
 return msg;
 }
}

Opps ... with two different interfaces it is working

Looks like the forum software chopped off the JIRA issue from your topic.

What was the error? There's nothing wrong with that construct assuming:

* There's no @Local or @Remote annotation on EchoService
* EchoServiceRemote does not also extend from EJBObject
* EchoServiceLocal does not also extend from EJBLocalObject

I actually found the problem. It was caused by my ejb-jar.xml entries

My entries were something like this:

<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar version="3.0">
 <enterprise-beans>
 <session>
 <ejb-name>PropertyService</ejb-name>
 <remote>com.emageon.properties.service.PropertyService</remote>
 <ejb-class>
 com.emageon.properties.service.ejb.PropertyServiceBean
 </ejb-class>
 <session-type>Stateless</session-type>
 <transaction-type>Container</transaction-type>
 </session>
 </enterprise-beans>
</ejb-jar>

The tags need to be changed to <business-remote>. Here is the corrected content.

<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar version="3.0">

 <enterprise-beans>
 <session>
 <ejb-name>PropertyService</ejb-name>
 <business-remote>com.emageon.properties.service.PropertyService</business-remote>
 <ejb-class>
 com.emageon.properties.service.ejb.PropertyServiceBean
 </ejb-class>
 <session-type>Stateless</session-type>
 <transaction-type>Container</transaction-type>
 </session>
 </enterprise-beans>
</ejb-jar>

Sorry. This post has ended up a little confusing.

[JBMETA-130] Was the error I got when trying to get EJB3 Session beans migrated from 4.2.x to 5.0.0 GA. In my case I was NOT trying to be EJB2.x compliant.

If you have this problem, check these items:

1. Make sure @Local and @Remote use a different interface.

2. Make sure any beans referenced in ebj-jar.xml file use the <business-remote> tag instead of the and use <business-local> instead of

[alrubinger]

Yep.

* @Remote references a business interface (EJB 3.x View)
* is a Remote Component interface (extends EJBObject, an EJB 2.x View)
* <business-remote> is the XML equivalent to @Remote
* There is no annotation for , we read it in via the return types of @Home create methods.
