JRE trouble

[ichwar]

So for some reason, my java runtime environment isn't working. For reference, I'm using ubuntu 9.04 64-bit. For a while it was working just fine, and then all of a sudden a couple of days ago, I tried to run a .class I had just compiled and I got this error:

Exception in thread "main" java.lang.NoClassDefFoundError: EmployeeTest/java
Caused by: java.lang.ClassNotFoundException: EmployeeTest.java
    at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:188)

    at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)
Could not find the main class: EmployeeTest.java.  Program will exit.

I tried removing jre, then reinstalling it, but still the problem persists. Has anyone had this problem? Does anyone know how to fix this?
Thanks.

It looks like it can't find a class or something within the class file. Of course I could be totally wrong, have you recently updated your JRE?

You're very close. I actually just got this problem resolved on another forum. Thanks for the help though.

My problem was that I was the .class extension on the end of the filename. eg. I was typing

java EmployeeTest.class

when the correct syntax is

java EmployeeTest

and java will automatically sort out the .class files itself.

Well, I guess a mod can lock or remove this thread now.

Set the class path to EmployeeTest.class file its the classpath problem ...
