ejb-ref in web.xml

[crosscourt]

Hi,

what is the correct syntax for the ejb-ref tag?
I tried the following but jboss complains about the ejb-link?

I am trying to deploy a ear file which contains a jar for my ejbs. I deploy a test.war file for cactus that test my "local" ejbs but i can't get the ejb-link right? I can still lookup the ejb through a jndi lookup but I want to use COMP_NAME lookup (is it better?).

where "ejb/user/UserValidatorLocal" is the local-jndi-name.

<ejb-local-ref>
<ejb-ref-name>ejb/user/UserValidatorLocal</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local-home>tds.interfaces.UserValidatorLocalHome</local-home>
tds.interfaces.UserValidatorLocal
<ejb-link>ejb/user/UserValidatorLocal</ejb-link>
</ejb-local-ref>

It used to work when i use
<ejb-link>tds.jar#user/UserValidatorLocal</ejb-link>

but now i deploy with tds.ear? and nothing works

thanks

and the error:

no ejb-link match, use jndi-name in jboss-web.xml

[adrian.brock]

<ejb-link>{<ejb-name> you want to reference}</ejb-link>

or

<ejb-link>relative path to jar#{<ejb-name> you want to reference}</ejb-link>

what if the jar is inside a ear?
so EAR has the ejb jar and web app war?

thanks

More info:

I'm trying to access local ejbs from normal java classes in my webapp inside the .war file through the java:comp namespace.

Prove to me you know what you are doing:

1) Show the ejb deployment descriptors, specifically what
<local-jndi-name> does the local interface have.
default is local/<ejb-name> if you don't change it jboss.xml

2) Show the packaging of the ear so I can see where the
ejb jar and war are located and what their names are.
jar -tf tds.ear

3) Show the web.xml you are actually using.

4) Post the full error message

yeah, i don't really know what i'm doing but here we go:

With xdoclet, i define the local jndi name
===============================
* @ejb.bean
* name="service/AdminService"
* type="Stateless"
* display-name="Administration Service Session Bean"
* local-jndi-name="ejb/service/AdminServiceLocal"
* view-type="local"
*
===============================
jboss.xml


<ejb-name>service/AdminService</ejb-name>
<local-jndi-name>ejb/service/AdminServiceLocal</local-jndi-name>


===============================

jar -tf tds.ear

META-INF/
META-INF/MANIFEST.MF
tds.jar
tds.war

======================================
AdminServiceDelegateImpl.java is a class inside the war file that tries to locate the AdminServiceEJB with the util class generated from xdoclet which uses
public static final String COMP_NAME="java:comp/env/ejb/service/AdminServiceLocal";

i tried diff combinations of <ejb-link> and only one jboss doesn't complain is
TradeDataService.jar#service/AdminService


thanks for you time

[crosscourt]

oh, TradeDataService.jar == tds.jar
sorry for the inconsistency

[adrian.brock]

<ejb-ref-name>service/AdminService</ejb-ref-name>
==
java:comp/env/service/AdminService

Regards,
Adrian

[crosscourt]

ok thanks,

i think this works
<ejb-ref-name>ejb/service/AdminServiceLocal</ejb-ref-name>

but what about ejb-ref for an external war for my test classes?

so i deploy tds.ear and test.war and i need to access the ejb from the classes in test.war?
