New model of JSP programming using custom tag and eXcelon Database for XML

The problem of web programming is that the source code is mixed with HTML and programming script. It makes the difficulty to manage and analyze. In this project, I suggest new model of JSP web programming using custom tag, JRun(Web server), and eXcelon(XML Database). All data are stored as XML data and it is appeared to user by XSLT with XPath. A programming script and HTML source is separated as a component. It improves reuse of each component, even the XSLT (view part) file can be reused with other component of java source. There is another advantage. The JSP source is very simple to analyze for the person who does not have knowledge of program. They can modify the source easily. Therefore, it leads saving the time to manage.
