template tag replace

[supamanxph]

Hi,

I have a Java web application using Struts and Spring. This application
contains a JSP page which displays a list of cars inside a table. I
want to allow my users to create their own template for this page, like
how blogger.com does. They use template tags to indicate what portion
of the template is to be filled with content. I tried to create custom
jsp tags in my app, but I only managed to create a tag which just
prints a line of code on the page. If anyone can help, please let me
know. Thanks.
