Four weeks ago I've uploaded my assignment and took the written exam. Today I've checked the database to find the following message:
Automatic failure. Your project does not execute in non-networked mode. In this mode, server and client run in the same JVM, and no network communication is allowed. When I typed "java -jar runme alone" I got a command-line message that said "Fatal error: java.lang.NullPointerException".
Needless to say that I've tested and retested my project on different machines and it worked on all of them.
Does anyone have experience with this or some tips how to proceed or what I could do to get some more info?
