First, Foreword For beginners, to perform JSP and servlet, Tomcat is a very good choice. You can also use RESIN, these two products can not spend a penny. Resin's support for XML is very good. Second, download, installation download address is the official site of the RESIN: http://www.caucho.com/. From this address, you can download: http://www.caucho.com/download/index.xtp, I downloaded the resin1.1.4 version. Download, extract to a directory, I use E: / RESIN114 as an example here.
