hi
I am trying to send a 2D byte array with some string content over a LAN network, but I am getting certain errors. This code is working perfectly in the local system. I was able to successfully pass content using ByteArray, but with 2D ByteArray, some strange sequence is happening.. This is the IDL file:



the moment the client calls the server method, I get this error at client side:



and at the server side :



This is the code where NullPointer seems to be coming from:




Please help me debug the stacktrace.

Thanks
