      Well I found the dreaded java.lang.NoClassDefFoundError problem on my computer few days ago.
      The test.java just prints hello world to screen, it compiles and runs fine with JCreator (IDE which I use to learn java)... when I tried to use command prompt to execute it just comes up with the error...

      I've read about reseting classpath and all but I didn't work, I just copied the classpath from JCreator settings and it doesn't seem to work either...

      Any ideas on how to solve this?
      C:\Temp>javac test.java
      C:\Temp>java test
