About calling EJB in another JVM
I tried , it might not what you want, but i really succeeded.
The code:

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import javax.naming.*;
import javax.rmi.PortableRemoteObject;
import org.jnp.interfaces.NamingContextFactory;
import org.jnp.interfaces.*;
import quay.myquayHome;
import quay.myquay;
import quay.myquayBean;

public class EJBClientTest extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=GBK";

public void init() throws ServletException {
}


public void doGet(HttpServletRequest request, HttpServletResponse

response) throws ServletException, IOException {
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
out.println("");
out.println("Remote EJB Test Panel");
out.println("");
out.println("<h1>Remote EJB Test Page.</h1>");

/////////////////////////////
try{

System.out.println("Before myEJBWork");
String tmpRst=myEJBWork();
System.out.println("After myEJBWork");
out.println(tmpRst);
}catch(Exception e){
out.print("Error when accessing EJB");
}
/////////////////////////////

out.println("");
}

public void doPost(HttpServletRequest request, HttpServletResponse

response) throws ServletException, IOException {
doGet(request,response);
}

private String myEJBWork() throws Exception{
try {
myquay tmpbean = findMyBeanHome().create();
return tmpbean.say();
}catch(NamingException e){
return "Error in myEJBWork";
}
}

private myquayHome findMyBeanHome()
throws NamingException {
Context context = getInitialContext();
Object object = context.lookup("quay/myquay");
context.close();
return (myquayHome)PortableRemoteObject.narrow(object,

myquayHome.class);
}

public Context getInitialContext()
throws NamingException {

Properties env = new Properties();
env.setProperty(Context.INITIAL_CONTEXT_FACTORY,

getInitialContextFactoryClassName());
env.setProperty(Context.URL_PKG_PREFIXES,

getURLPackageInterface());
env.setProperty(Context.PROVIDER_URL, getNameServerURL());

InitialContext jndiContext = new InitialContext(env);
return jndiContext;
}

private String getInitialContextFactoryClassName(){
return "org.jnp.interfaces.NamingContextFactory";
}

private String getURLPackageInterface(){
return "org.jnp.interfaces";
}

private String getNameServerURL(){
return "localhost:1099";
}
