Hi, I am a greenhorn of Java. Please help me. I am using Tomcat as my servlet container, and I create a web application under the directory of "$TomcatHome$/webapp". All the Jsps run well, but when I put a servlet under "/WEB-INF/classes" and run it, I meet an error: "The requested resource (/jsp10/servlet/srv_intro) is not available". I have specified the context for this web application in server.xml. Waiting for your help.
