I get the error below when trying to run an executable jar file. The file only contains a main with one line “System.out.println(“Woo!”);” and runs fine in eclipse.
I’m not sure how to read these error messages.

Your compiled class is in jre 1.5 and your system default jre is different(might be 1.6).
compile your code in same version of jre.
