Hi,
I was following this guide (Apache Derby Tutorial) and have followed every set of it up until step 3 where I tried to compile the SimpleApp program that comes with the javadb.
It compiles but i get this message:

Code:

Note: SimpleApp.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Not a major problem though, when I try to run it i get this error message:

Code:

Exception in thread "main" java.lang.NoClassDefFoundError: SimpleApp
Caused by: java.lang.ClassNotFoundException: SimpleApp
        at java.net.URLClassLoader$1.run(Unknown Source)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(Unknown Source)

        at java.lang.ClassLoader.loadClass(Unknown Source)
        at java.lang.ClassLoader.loadClassInternal(Unknown Source)

This isn't the error for not having the class path set because I had that earlier, this is something different I think

If anyone can help me with this I'd be very grateful.
