Can compile but can't run....
843804Sep 17 2004 — edited Oct 31 2004Last year I compiled and ran programs and applets with the Java SDK Version 1.4.0 on Windows XP. This year I am basically going thru the same motions, but now I can compile programs but not run them. The error that I get using the DOS prompt command is
C:\VMBwork>java HelloWorld
Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorld
I moved to a new Computer Lab over the summer, so the technicians loaded j2sdk1.4.2_04 with NetBeans IDE. I have set the path in XP to c:\j2sdk1.4.2_04\bin and the classpath to c:\Program Files\Java\j2re1.4.2_04\lib\ext. This appears to be the same set up as last year...but no java programs run.
I even tried loading j2sdk1.4.2_05 new on my computer without Netbeans with the same path changes, but to no avail. Any suggestions? The students are really anxious to get into programming.
