When I'm trying to run a java application.

java.lang.ClassNotFoundException: Loader.class

That looks like the contents of a browser's java console.
How does a browser get involved when you are trying to run a java application?
How are you executing the program? Please show the command line contents.
If it is an applet, please post the HTML you are using.

The message says that the JVM can not find the class named: class in the package Loader.
If the class name is Loader and not Loader.class, try removing the .class so that you are using the class name and not the filename.
