I am getting the message "NoClassDefFoundError: com/ibm/ws/profile/WSProfileException", when I build my project using ant.

>>>>wsanttasks.jar doesn't have com/ibm/ws/profile/WSProfileException class.

>>>> I dont know which jar is having this class.


*****It will be great if somebody can tell me which jar contains this class.
