JCreator issues

[baseballplayer13]

I'm trying to get started with java using JCreator. I'm sure that I installed it correctly and got the directories for the JDK and API files correct, but whenever I try to compile my files or projects i get this error:

--------------------Configuration: Test - JDK version 1.6.0 <Default> - <Default>--------------------
