struts 2 in eclipse

[Ritesh Badwaik]

hi all,
I have struts 2 application which runs successfully but when I tried it using Eclipse Version: 3.3.2 , it gives error as
-----------------------------
HTTP Status 404 -
type Status report
message
description The requested resource () is not available.
Apache Tomcat/5.5.27
-----------------------------------
the application runs fine till I add struts.xml to WebContent/WEB-INF/classes folder. After adding struts.xml, it gives above error.
Can anyone tell me where to put struts.xml file ?

Thanks
Ritesh
