I am learning Javaservlets. So I downloaded J2EE SDK1.3. When I launched j2ee server, it involves apache web server and tomcat automatically. Then I copied a "Hello world" serlet sample, and compiled it. But I don't know where I should put the .class file. The file structure of j2ee sdk is totally different from which described in the book. Can you give me some suggections? Thanks a lot.
