Exception in thread "main" java.lang.UnsupportedClassVersionError:

i keep getting this message when i try to run java class files. There is no problem compiling.

I know what the problem is. My JVM is a different version to my JDK. However i have never used either before on this machine so i have no previous versions installed. I just downloaded it all in one go from the sun website.

Does any one have any tips or ideas on what to do?

Probably some other application installed an older version jvm and your system is finding this version before it finds the JDK version. A simple fix might be changing your Path variable so the JDK bin directory is the first entry in the list of paths.

you are trying to run it on a later version than the one used to compile this class

If the software that you downloaded was compiled with jdk1.5 i.e. using new features etc. and your jvm is the one previous to that then this exception is raised.
