How to plugin Struts framework in SAP Web AS 6.3

Hi,

I am newbie to SAP Web AS 6.3. I would like to know how to plugin the Struts framework in SAP Web AS 6.3. I am not able to find any docs related to this which leads to lot of problem when am trying to plugin on my own. Please see the below mentioned exceptions.

(A) javax.servlet.jsp.JspException: Cannot find message resources under key org.apache.struts.action.MESSAGE

at org.apache.struts.util.RequestUtils.message(RequestUtils.java:819)

(B) javax.servlet.jsp.JspException: Cannot find ActionMappings or ActionFormBeans collection

at org.apache.struts.taglib.html.FormTag.lookup(FormTag.java:858)

I would be greatful if i know a small hint to solve this problem which I got stuck for the last two days.

Thanks
