"Unsupported major.minor version 51.0"

It means that you compiled your classes under a specific JDK, but then try to run them under a different version.

I compiled the version 1,7 (jdk1.7.0_05) and correspond to the well and run on this one, compiled by Eclipse can not set up that the true test?

figured out what was the problem I have is 64 bits, and put 32 and it worked, just tell me where there is a table of Antharas, Valakas and other great bosses
