SASParser exception when using struts1.1 with weblogic8.1

["Prasad, Kamakshya" <kp...@capitalservicing.co.jp>]

Hi,
 
I am using Struts 1.1 with weblogic 8.1 as the application server, for
building a web based application.
 
Whenever I starts the server or redeploys the application it throws this
exception though the application works fine. 
 
java.lang.ClassNotFoundException:

This class is already available in weblogic.jar. Still why's the server
not able to find it.
 
Any clues?
