is the exception coming during the application startup OR when accessing some of the pages?

check whether the struts-config file definition in web.xml under ActionServlet entry is correct or not? Like following is the entry for struts-config.xml

      <init-param>
         <param-name>config</param-name>
         <param-value>/WEB-INF/struts-config.xml</param-value>
      </init-param>

struts-config.xml should be there if u placed it under WEB-INF folder.
rdy1437Author Commented:
the web.xml is configured correctly, placed under WEB-INF. Quite weird because this application is running successfully on Resin. But when I moved it to tomcat, Im getting this error.
