Yesterday, I saw the article on the establishment of EJB in Eclipse. I also have a big gain. I also wrote a cat and the cat and the tiger. But just run it in the command. Later, I wanted to be called in servlet, I haven't successful success. Today, I also read an article about writing servlets in Eclipse, which is very simple.
Summary: Eclipse is very good, it is to configure trouble, but the Internet can get some information!!!
