Hi.
A working model is to create two Initial Context-s for each server.
Use a "dedicated.connection=true" property to create the context.
The "dedicated.connection" however leads to resource leakage, and if you
keep creating more and more of them you will eventualy get
"java.lang.OutOfMemoryError: Can not create native thread" at some 200-300
contexts.
If you create an context for both servers, and then use them later you
might not have this problem.
public static Context[] connections;
public void ejbCreate(){
if ( connections != null ) return;
Hashtable env = new Hashtable();
// Use any of these.
env.put("dedicated.connection", Boolean.TRUE );
// env.put("dedicated.connection", "true");
// Set up user, pass,
// factory (RMIInitialContextFactory).
env.put(".......", "...."); // Set up things
connections = new Context[2];
// For The first server
env.put(Context.PROVIDER_URL, "ormi://Comp1/App1");
connections[0] = new InitialContext(env);
// Now for the other server
env.put(Context.PROVIDER_URL, "ormi://Comp2/App2");
connections[1] = new InitialContext(env);
}
public void connectServer1(){
connections[0].lookup("MyBean1");
}
public void connectServer2(){
connections[1].lookup("MyBean2");
}
You DO understand this is Orion-specific, right?
Good luck. Lachezar.
