<div bgcolor="#ffffff" text="#000000"> There are explicit
examples in C++ in the omniORB source tree. If you mirror
that code in Java you should have some success.<br>
<br>
But as something is failing in your Java code you should
debug that. I'll suggest that you confirm that you can
retrieve valid NameComponent pieces from the naming service
for each level of the name you have registered and are
trying to retrieve. And unnest the call to resolve() so you
can see what the result of that is. But first, you could use
a naming service listing utility to examine how the naming
service is being used by your server.<br>
<br>
If you are new to CORBA, you will find it very useful to
have a reference book and tutorial. I have found that, no
matter which language you are using, the Advanced CORBA
Programming with C++ by Henning and Vinoski is the book
worth having.<br>
<br>
Oh, you *are* using JacORB, right? The ORB shipped with Java
is deficient (or at least used to be and I haven't heard
that it has gotten better).<br>

As the exception says, the name you have
looked up is not found. The eg3<br>
example uses the name
test.my_context/Echo.Object . You need to
either<br>
create the two NameComponents separately,
or use the<br>
NamingContextExt::resolve_str method that
will take the string form.<br>
<br>
Cheers,<br>
<br>
Duncan.<br>
