Description

I'm trying to deploy a servlet that calls an EJB. I can
deploy the EJB and call if from a command-line Java client, so I think
that part works, thanks to the dev list for help with JNDI.

I did the usual stuff in the servlet, but when I add

<ejb-ref>
<ejb-ref-name>g6o/SSEJB</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>g6o.ejbclient.StatelessSessionHome</home>
<remote>g6o.ejbclient.StatelessSession</remote>
</ejb-ref>

to web.xml I get a stack trace when I run the deploy tool.

org.apache.geronimo.deployment.DeploymentException: Remote interface class not found: g6o.ejbclient.StatelessSession
at org.apache.geronimo.jetty.deployment.JettyModuleBuilder.assureInterface(JettyModuleBuilder.java:593)
at org.apache.geronimo.jetty.deployment.JettyModuleBuilder.assureEJBObjectInterface(JettyModuleBuilder.java:573)
at org.apache.geronimo.jetty.deployment.JettyModuleBuilder.addEJBRefs(JettyModuleBuilder.java:491)

etc...

I've got the EJB interfaces in a jar in the war file's WEB-INF/lib
directory, but I also tried putting the jar with the EJB interfaces in
geronimo's lib directory with the same result.

Copying my ejb client jar to geronimo's repository and adding an element to geronimo-jetty.xml:

<dependency>
<uri>g6o-ejb-client.jar</uri>
</dependency>

...allows the deployment to get farther, but then I get a message about how references that aren't ejb-link are not implemented, so I cut the ejb-ref element out of web.xml to make the deployment work, and when my servlet tries to look up the EJB I get:
