During the undergraduate period, I have done a database development, I have done a web application (based on ASP, then .NET has not yet raised). It has been specializing in research J2SE and J2ME technology in the past two or three years. Of course, the general Server / JSP program is not a problem. I looked at Struts today, I found that I have been thrown behind J2EE technology, this is just a MVC framework, there is a larger EJB technology. It is necessary to adjust the focus on this period. I came J2EE :)
