[Processing.net libraries] Error Client got end of stream

I am trying to debug a program to do so I have test 2 programms from Processing.net librarie :

I got the two times the same error which is “Client got end of stream” follow by Null pointer exception for the first example with write() and just “Client got end of stream” with the second one.

The only thing that I have changed from the exemple is the port number according to my Tomcat server. Did I miss something or should I use another version of processing to debu my programm. I am on the 3.5.3.

Thanks in advance for your help :slight_smile:
