NoClassDefFound Error Suddenly Appearing [message #219018] Sat, 30 June 2007 01:16 Go to next message

Very suddenly, any class I attempt to run, either from Eclipse or the
command line, is throwing a NoClassDefFound exception. I've tried
altering the classpath, to no avail. I'm running OS X JVM 1.5.0, which I
recently upgraded to. Are there any known problems with this JVM? Should
I attempt to remove and reinstall it, and if so, how would I go about that?

What class is it complaining that it can't find?

Make sure you don't have two copies of the class "visible" when you are
starting it.
