Catching error caused by InitialContext.lookup
- by Martin Schröder
I'm developing a command line client (Java SE6) that now needs to talk to a Glassfish 2.1 server.
The code for setting up this connection is
try {
final InitialContext context = new InitialContext();
final String ejbName = GeneratorCancelledRemote.class.getName();
generatorCancelled = (GeneratorCancelledRemote) context.lookup(ejbName);
}
catch (Throwable t) {
System.err.println("--> Could not call server:");
t.printStackTrace(System.err);
runWithOutEJB = true;
}
I'm now testing it without a running server and the client (when run from Eclipse 4.2) just bombs with

It's o.k. for now (while I'm still in development) that it bombs, but it does this repeatedly and the catch clause is never reached (even though I'm catching Throwable) - the message is not printed.
So how can I handle connection errors during lookup in my program?
