How do youi call an EJB from a composite app

Question

I created a simple composite application, called testserve.
Here is the entire body of the implementation class, testserveBeanImpl.java
package com.sap.demo.testserve.modeled.appsrv.testserve;
import com.sap.demo.*;
@com.sap.caf.dt.CAFWebService(name="testserve")
@javax.jws.soap.SOAPBinding(style=javax.jws.soap.SOAPBinding.Style.RPC, use=javax.jws.soap.SOAPBinding.Use.LITERAL)
@javax.jws.WebService(name="testserve", serviceName="testserve", portName="testservePort", targetNamespace="http://www.sap.com/caf/demo.sap.com/testserve/modeled", wsdlLocation="META-INF/wsdl/testserve.wsdl")
@javax.ejb.Stateless(name = "com.sap.demo.testserve.modeled.appsrv.testserve.testserve")
@javax.ejb.Local(value = { com.sap.demo.testserve.modeled.appsrv.testserve.testserveServiceLocal.class })
@javax.interceptor.Interceptors(value = { com.sap.caf.rt.interceptors.LogInterceptor.class })
public class testserveBeanImpl extends
          com.sap.demo.testserve.modeled.appsrv.testserve.testserveBean {
                //these two lines are used to inject an EJB which is packaged in the EAR
     @javax.ejb.EJB (beanName="com.sap.demo.TestbeanBean")
               private com.sap.demo.TestbeanBean theTestBean;
     @com.sap.caf.dt.CAFOperation(name = "serviceTest1")
     @javax.jws.WebMethod(exclude=false, operationName="serviceTest1")
     @javax.jws.WebResult(name="outputParameter1")
     public java.lang.Integer serviceTest1() {
                               //test1() just writes to console, simple test to test EJB connectivity
          theTestBean.test1();
          return 1;
There is a second ejb project called testejb which contains the stateless session bean TestbeanBean.
The code compiles fine as typed above.
However, when deployed, I get the following exception, which I will post in a reply, since this post is too long. I am sure that I neglected to
set up something so that the testserve service can find the EJB TestbeanBean at runtime, but I need some
guidance. I have searched the help for a couple days and have not found anything useful. Is there a step by step
explanation for configuring this?  To be clear, I want a web service created in the Composition Application perspective
to be able to call an EJB in an EJB project. I don't want to create a web service out of the EJB (TestbeanBean) for performance reasons. Thanks.
The service works fine when the 3 lines relating to  TestbeanBean are removed.
