Hi,
to implement struts applications with eclipse you have to use different plug ins .you are saying new to struts so write struts application on plain notepad to understand frame work.
follow below things
1 unzip struts folder
2 copy jar files from lib of struts folder to WEB-INF/lib of your application
set class path to struts.jar,then compile them
i thought you are familiar with web application architecture,Tomcat,
Servlets ,
jsp.
