java.lang.NoClassDefFoundError: junit.framework.TestCase

I receive the following error while trying to access a servlet in Tomcat:

java.lang.NoClassDefFoundError: junit.framework.TestCase

I have the path to junit.jar setup in the classpath.

Any ideas?

Many thanks in advance

----------------------------------------------------------------------------------
import junit.framework.*;
import com.meterware.httpunit.*;
public class SimpleRequest extends TestCase {
WebConversation wc = new WebConversation();
String base_url = "http://www.msn.com";
public SimpleRequest(String name) {
super(name);
}
public void testRequest() {
WebResponse resp = null;
try {
resp = wc.getResponse( base_url );
} catch (java.net.MalformedURLException e) {
System.out.println("Bad url: " + e);
} catch (java.io.IOException e) {
System.out.println("IO Err: " + e);
} catch (org.xml.sax.SAXException e) {
System.out.println("XML Err: " + e);
}
assertEquals(200, resp.getResponseCode());
}
};

It does run fine if I do the following command:

java junit.textui.TestRunner SimpleRequest


But why do I get the error while running via a web browser?

P.S. I know that currently, no text would print to the browser, but in the future I could write code that would.

The junit jar needs to be in the WEB-INF/classes folder for jsp's in Tomcat to find it. The environment variable CLASSPATH will not work.

Thanks Nemi, that was easy :-)

Now, I get the following error:

root cause
java.lang.InstantiationException: SimpleRequest

any ideas?

I am not familiar with junit, so I do not know what you are trying to do with it. Here is what the API docs say about that exception
