Hi David,

Thank you for your reply. Here is what your requested information, and
additional config. info from several files in tomcat. It is completely
same error where i sent the link in my previous post. I am ready to
provide extra information or any help if possible.

Tomcat versions: 5.0.28, 5.5.20
JDK versions: 1.4.2_10, 1.5.0_06
OpenEJB version:1.0

Best Regards.

INFO :

this is from my test.jsp:

<%
javax.naming.Context initCtx = new javax.naming.InitialContext();

Object object = initCtx.lookup("java:comp/env/ejb/SapCacheBean");
com.medtronic.minimed.gs.scs.ejb.SapCacheHomeRemote home =
(com.medtronic.minimed.gs.scs.ejb.SapCacheHomeRemote)
javax.rmi.PortableRemoteObject.narrow(object,
com.medtronic.minimed.gs.scs.ejb.SapCacheHomeRemote.class);
com.medtronic.minimed.gs.scs.ejb.SapCacheRemote bean = home.create();
%>
<%= bean.test() %>

This is ejb-ref definition from web.xml:

<ejb-ref>
<description> EJB Reference to the bean deployed to OpenEJB </description>
<ejb-ref-name>ejb/SapCacheBean</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>com.medtronic.minimed.gs.scs.ejb.SapCacheHomeRemote</home>
<remote>com.medtronic.minimed.gs.scs.ejb.SapCacheRemote</remote>
</ejb-ref>

And finally this is from context.xml of my test web app:

<Ejb name="ejb/SapCacheBean"
    type="Session"
    home="com.medtronic.minimed.gs.scs.ejb.SapCacheHomeRemote"
    remote="com.medtronic.minimed.gs.scs.ejb.SapCacheRemote"/>

    </parameter>
    <parameter>
        <name>openejb.naming.factory.initial</name>
        <value>org.openejb.client.LocalInitialContextFactory</value>
    </parameter>

    <parameter>
        <name>openejb.ejb-link</name>
        <value>SapCacheBean</value>
    </parameter>
</ResourceParams>
