Reference/link to local interface in different jar (Jboss 2.
Hi.
This looks long but please have a look, just trying to be thorough.
Does anyone know whether jboss supports the feature described in the ejb2.0
dtd whereby a bean can reference another bean packaged in a seperate jar file?
Here is the bit i'm talking about (from http://java.sun.com/dtd/ejb-jar_2_0.dtd ):
[pre]
<!--
The ejb-link element is used in the ejb-ref or ejb-local-ref
elements to specify that an EJB reference is linked to an
enterprise bean.
The value of the ejb-link element must be the ejb-name of an
enterprise bean in the same ejb-jar file or in another ejb-jar
file in the same J2EE application unit.
Alternatively, the name in the ejb-link element may be composed of a
path name specifying the ejb-jar containing the referenced enterprise
bean with the ejb-name of the target bean appended and separated from
the path name by "#". The path name is relative to the ejb-jar file
containing the enterprise bean that is referencing the enterprise bean.
This allows multiple enterprise beans with the same ejb-name to be
uniquely identified.
Used in: ejb-local-ref, ejb-ref
Examples:
<ejb-link>EmployeeRecord</ejb-link>
<ejb-link>../products/product.jar#ProductEJB</ejb-link>

I'm having problems getting this to work. When deploying beanA, jboss says
"Cause:org.jboss.ejb.DeploymentException: Bean beanC.jar#ejb/bean_c not found within this application."
What I'm doing:
1. SFSB BeanA that wants to get a:
- remote reference to BeanB
- local reference to BeanC
2. BeanB is deployed in its own jar (beanB.jar)
3. BeanC is deployed in its own jar (beanC.jar)
4. BeanA is deployed and then error happens....
