jboss and junit

Hello,

I have written a junit testcase class for EJB's and i am running it through a jsp.I have set junit.jar file in the classpath. I get the following error

junit.framework.TestCase.class not found

So i copied the junit.jar file in the C:\jboss\server\default\lib directory
then i am getting the following error
