Hi, What�s the code at line 22 of TestSampleServlet.java? As Mallinath said, the problem is that you've compiled your code (in your IDE probably) with one version of a jar (which had the API at line 22 of your code) and you're trying to execute it with a different version of the jar which does not support the API from line 22 of your code.

I created a whole new instance of Tomcat 4.1.24 from Apache, setup my catalina_home variable, started up tomcat and all is well. Then, I added junit-3.8.1.jar, cactus-1.6.1.jar, aspectjrt-1.1.1.jar and commons-httpclient-2.0.jar. Next, I restarted Tomcat, then tried http://localhost:8080/test/ServletTestRunner?suite=TestSampleServlet and I still get the same error. Also, I just download the .class files for SampleServlet.class and TestSampleServlet.class from the Apache site and put them in <tomcat home>\webapps\test\WEB-INF\classes. There are jar files in <tomcat home>\lib and <tomcat home>\server\lib.
