Does anyone remember how to change the java version that a project uses to compile classes in MyEclipse?  I'm getting a "unable to access jar file" and then an "invalid or corrupt jar file" message when I try to run my JAR.  I'm guessing that I may have the wrong version number (1.5 instead of 1.4)  in my manifest file.

Your  helps is greatly appreciated

Check the installed JREs and also the compiler compliance level in the preferences section
