Install java from blackdown.org or java.sun.com and your problem is solved. You are using gcj and it is and incomplete jvm

With the standard (Sun) Java interpreter, there's no such thing as a "-jar" argument.

Instead, you specify the .jar file as part of your classpath.

EXAMPLE:

java -cp myfile.jar MyMainClass
