Hiya,

I was running my java project fine, but I suddenly started getting the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: DrawConnect4
Caused by: java.lang.ClassNotFoundException: DrawConnect4
at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:205)
at java.lang.ClassLoader.loadClass(ClassLoader.java:321)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294 )
at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
Could not find the main class: DrawConnect4. Program will exit.

For all my classes and my class files all disappeared. I have a project due in tomorrow morning and I really need to run these classes!

Ubuntu 10.10.

Thanks

You haven't really given enough information to help, but I'll speculate
that your project has build path problems that must be resolved. What
shows up in your Problems view?
