CORBA - OBJECT_NOT_EXIST exception

[Dan Murphy]

Hi,

I'm writing a java CORBA client, using the Visibroker ORB. Sometimes when I call methods on the remote object references I get the following exception

org.omg.CORBA.OBJECT_NOT_EXIST:   vmcid: OMG  minor code: 0  completed: No

Is there some way that I can check beforehand whether this exception will be thrown, i.e. whether the remote object still exists? I thought that I could do it like this:

if (myRef._non_existent()) {
 
// get a new myRef
} 
 
myRef.doRemoteMethod();

But I've found that _non_existent() throws exceptions. Is there a better way to check for the state that causes an OBJECT_NOT_EXIST exception?

Regards,
Dan

Why not handle the exception and get a new reference when the exception occurs?
