Thanks. I have generated my stubs with idlj tool from JDK 6.0. I
googled that I might have wrong bootclasspath - the ORB is usually
needed to be in the bootclasspath. So I have added JacORB to
bootclasspath and it does not work.

It seems it has nothing to do with Yoko. I created JacORB server and I
am trying to reach it with JacORB client with the same exception :-(

Hi Lukas,

No, I don't believe you will need to have a name service running for the
example that you mentioned.  This should be a straight forward setup using
the Yoko binding and an a CORBA client.

Usually, you get a BAD_PARAM exception when doing a narrow on an object
which is of the wrong type, for example, trying to narrow something as a
calculator when it is not.  However, I don't see why this could happening
yet in your code.  I will try and set up a small test using the code you
provided to see if I can see what is happening.

I'll let you know what I find out.

Cheers,
Darren
