Hi again!
I want to look at them as two separate beans, only with the same interfaces.
They are both declared and have different names, the only thing they have in
common is the remote and home interfaces. I really would like to be able to
access them both. But when I do the references only one of them works. An
example of how it can look:
<session>
<description>no description</description>
<display-name>Tester</display-name>
<ejb-name>Tester</ejb-name>
<home>test.TesterHome</home>
<remote>test.Tester</remote>
<ejb-class>test.TesterEJB</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>
<ejb-ref>
<ejb-ref-name>ejb/test/Test1</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<ejb-link>Test1</ejb-link>
<home>test.TestHome</home>
<remote>test.Test</remote>
</ejb-ref>
<ejb-ref>
<ejb-ref-name>ejb/test/Test2</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<ejb-link>Test2</ejb-link>
<home>test.TestHome</home>
<remote>test.Test</remote>
</ejb-ref>
</session>
<session>
<description>no description</description>
<display-name>Test1</display-name>
<ejb-name>Test1</ejb-name>
<home>test.TestHome</home>
<remote>test.Test</remote>
<ejb-class>test.Test1EJB</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>
<env-entry>
<env-entry-name>test1/password</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
<env-entry-value>PASWD1</env-entry-value>
</env-entry>
<env-entry>
<env-entry-name>test1/hosturl</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
<env-entry-value>http://www.test.com/demo/t1.jsp</env-entry-value>
</env-entry>
</session>
<session>
<description>no description</description>
<display-name>Test2</display-name>
<ejb-name>Test2</ejb-name>
<home>test.TestHome</home>
<remote>test.Test</remote>
<ejb-class>test.Test2EJB</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>
<env-entry>
<env-entry-name>test2/password</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
<env-entry-value>PASWD2</env-entry-value>
</env-entry>
<env-entry>
<env-entry-name>test2/hosturl</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
<env-entry-value>http://www.test.com/demo/t2.jsp</env-entry-value>
</env-entry>
</session>

You're in luck, because this is a EJB feature. ejb-jar.xml is defined by
JavaSoft and is the same everywhere you go in EJB country.
You simply can not do this. When referencing one bean from another you
are essentially being just another client of that bean. And since
clients can not, and should not, know anything about the current
implementation, you are not able to declare which implementation bean to
use.
