Hi there,
I'm trying to access an entity bean from a stateless session bean and I'm
running into a "javax.naming.NameNotFoundException" while executing the
followin statement:
ctx.lookup("java:/comp/env/ejb/MyBean");
ctx is an InitialContext without parameters. Both EJBs are running on the same
server and and are in the same archive.
My ejb-jar.xml contains the following code (I will leave out tags like
cmp-fields in this posting, btw: the session bean serves additionally as a web
service):
<session>
<display-name>Demo</display-name>
<ejb-name>Demo</ejb-name>
<home>com.test.DemoHome</home>
<remote>com.test.Demo</remote>
<service-endpoint>com.test.DemoSEI</service-endpoint>
<ejb-class>com.test.DemoBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<ejb-ref>
<ejb-ref-name>MyEntity</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<home>com.all.MyEntityHome</home>
<remote>com.all.MyEntity</remote>
<ejb-link>MyEntity</ejb-link>
</ejb-ref>
</session>
<entity>
<description>Test entity bean</description>
<ejb-name>MyEntity</ejb-name>
<home>com.all.MyEntityHome</home>
<remote>com.all.MyEntity</remote>
<ejb-class>com.all.MyEntityBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.String</prim-key-class>
<reentrant>false</reentrant>
<cmp-version>2.x</cmp-version>
<abstract-schema-name>MyEntity</abstract-schema-name>
</entity>
My openejb-jar.xml contains the following code (I'll leave out things like
cmp-mappings in this posting)
<enterprise-beans>
<session>
<ejb-name>Demo</ejb-name>
<jndi-name>Demo</jndi-name>
</session>
<entity>
<ejb-name>MyEntity</ejb-name>
<jndi-name>MyEntity</jndi-name>
</entity>
</enterprise-beans>
As I said before, a lookup is not possible.
During several tries I changed the <jndi-name> for the entity bean in
openejb-jar.xml to <jndi-name>ejb/MyEntity</jndi-name>
and the <ejb-ref-name> in ejb-jar-xml to
<ejb-ref-name>ejb/MyEntity</ejb-ref-name>
And magic: the lookup works. Unfortuanally I can not understand why. Is a
leading "ejb/" required for jndi name? I don't think so, because I could not
find anything similar in any tutorial. But what is the difference or what are
the underlying rules?
