Well, I guess that I am totally lost:( This is the first time I use Tomcat and I don't know nothing about it. I already installed JDK and set the environment variable such as JAVA_HOME and set the class path very well. I used java before and every thing is fine. I am going to use the ROOT folder to store my servlets. There is a web.xml file in that folder and I only alter the information about the servlet that I am going to put, which is the HelloWorld. I only wrote the HelloWorld.java and put them in the ../ROOT/WEB-INF/classes folder. Actually I also tried to put the HelloWorld.java to the ../Servlet-Examples/WEB-INF/classes. I was hoping that when I invoke the http://localhost:8081/servlet/HelloWorld, it will automatically compile the HelloWorld.java and make the class. I tried to read the tomcat documentation but I am still not be able to make any progress. Please give me a thorough and step-by-step guidance. Thank you very much. Brian
