[Middlegen-user] Error in web.xml with <ejb-local-ref> ?

[M-Leander Reimer]

Hi there,

I compiled the sample and everything runs fine. When I deploy the EAR
unter JBoss 3.0.0, I get something this:

org.jboss.deployment.DeploymentException: Error during deploy; - nested
throwable: (javax.naming.NamingException: ejb-local-ref: ejb/Flight,
target not found, add valid ejb-link)

So I look into the generated web.xml and I find:

<ejb-local-ref>
<ejb-ref-name>ejb/Person</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<local-home>airline.ejb.interfaces.PersonLocalHome</local-home>
<local>airline.ejb.interfaces.PersonLocal</local>
</ejb-local-ref>

I guess this is necessary to use the local interfaces of the EJBs from
other beans (an servlets) in the webapp.

1. What would the correct value of the optional <ejb-link> attribute be,
so it would work?

2. Why are there more than one <ejb-local-ref> declarations per bean (up
to 5 times in case of the person bean) in the web.xml? Is this required?

3. Can I modify the behaviour of Middlegen or XDoclet somehow, so a
correct deployment descriptor is generated?


Thanks for the help guys!

I haven't tried to deploy the sample on JBoss (I don't really know
JBoss), so my below comments are guesses only.

I have no idea what this could be. I suggest you ask the JBoss guys. If
you find out what the problem is, I'd be grateful if you enlighten me.
It would be nice if this worked without a link too.

Correct, that's the intention, and WebLogic Server doesn't complain.

See http://xdoclet.sourceforge.net/webdoclet.html#web_ejb-local-ref

Middlegen's output for CMP EJBs can be modified in the following
Velocity template:
middlegen\plugins\entitybean\src\middlegen\plugins\entitybean\entity-
cmp-20.vm

To modify XDoclet's output, see the various *.xdt files under
xdoclet/modules/ejb
