Hello All -
I'm new to jBoss, so bear with me, please, in case I've left out something
obvious.
I am having problems with an Entity (BMP) bean that is attempting to access
an external Stateless Session bean running on the same server (but within a
separate JAR).
When executing (within my entity bean named BMPTest):
DBHome DBBeanHome =
(DBHome)PortableRemoteObject.narrow(objref,DBHome.class);
I receive the error:
[BMPTest] TRANSACTION ROLLBACK EXCEPTION:id may not be null; nested
exception is:
java.lang.Error: id may not be null
[BMPTest] java.lang.Error: id may not be null

org.jboss.ejb.plugins.jrmp.interfaces.HomeProxy.invoke(HomeProxy.java:221)
etc.
For my BMPTest beans ejb-jar.xml, I added:
<ejb-ref>
<ejb-ref-name>MyDBBean</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>DBHome</home>
<remote>DB</remote>
</ejb-ref>
and in jboss.xml:
<ejb-ref>
<ejb-ref-name>MyDBBean</ejb-ref-name>
<jndi-name>MyDBBean</jndi-name>
</ejb-ref>
I'm moving these beans from j2ee server, so I haven't built some simpler
code to access DBBean directly yet, which will be my next step to isolate
the problem.
I'm using a JSP page to call a JavaBean, which calls the BMPTest entity
bean, which attempts to call upon DBBean Session bean - the failure occurs at:
(DBHome)PortableRemoteObject.narrow
Any ideas would be appreciated.
Also, I haven't found a lot of info on exactly what I should be setting
within the manfest.mf file - I'm not sure if its related or not, but its
one area of grayness....
Thanks!
tyson
