Hello,
I get run time error messages when I run a modified version of Rifidi
emulator 1.5 (server) on one PC and a modified version of the LLRPHelloWorld
(client) on another PC.
Parts of the output in the client console below:
... output omitted ...

I have not modified the code for llrp.jar and the rest of the LLRP messages
are being output correctly, so I am not sure what is causing this. Any help
will be appreciated.

Sana
