[Bluej-discuss] 7.47 creating jars - linux problem

[ric104]

Thanks for that, I solved it by running BlueJ as root

The problem Im haivng now is when i run "java -jar whatever.jar" I am getting the following message:

Exception in thread "main" java.lang.UnsupportedClassVersionError: Game (Unsupported major.minor version 49.0)
        at java.lang.ClassLoader.defineClass0(Native Method)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:539)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:235)
        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:302)

Ouch!

And here is what is says when I actually use java 5

root at icedearth[/usr/lib/jvm/java-1.5.0-sun/bin]# java -jar /home/icedearth/test.jar
no suitable method `main' in class
root at icedearth[/usr/lib/jvm/java-1.5.0-sun/bin]#

I have checked that main exists and run it in BlueJ ok, any ideas?

Thanks

Roland
