CORBA works outside servlet but not inside

[Benjamin Dover]

Hi,
I have a Java client talking to a C++ server using CORBA.
The program runs perfectly when the code is executed
from the main method and the program is run from
the command line. However, the code does not run
inside a servlet.

Can someone point me in the right direction?
Specifically, I get a ClassDefNotFoundError
for one of the Helper classes.

I am using Orbacus for this purpose.

Thanks
Ben

Sorry, it's not a ClassDefNotFoundError, but the following:

Internal Servlet Error:

I have a similar problem, still trying to figure it out. The code
snippet below works fine as a stand-alone java program but inside a
servlet/web service hangs forever when narrowing the context. I'm using
Orbix/OmniOrb and Sun Java System Application Server Platform Edition
8.1.

Properties props = new Properties();
props.put("org.omg.CORBA.ORBInitialPort", "6078");
props.put("org.omg.CORBA.ORBInitialHost", "localhost");//works
with a hard-coded IP address as well
props.put("org.omg.CORBA.ORBInitRef",
"NameService=corbaloc::localhost:6078/NameService");

String []st = null;
ORB orb = ORB.init(st, props);
org.omg.CORBA.Object o = orb.resolve_initial_references(
"NameService");
NamingContext nc = NamingContextHelper.narrow(o);
