[Planetlab-users] Java Socket Problem

[Sercan Demirci]

Hi everybody,

We have a problem about creating a socket for sending and receiving an 
object in java.
Sometimes we get an error message like this; "socket exception: because 
of null pointer"..

One node sending an object successfully but other node gives socket 
exception because of null pointer error message.
We see that some nodes do not create socket some ports. For example in 
our tests, we are using port number 2500 for communicating between nodes.

How can we solve this socket problem? Can i solve this problem changing 
the port number?

Best regards,
Sercan
