Build problem using ANT in WAS6.1

[Deboshree Roy]

Hi,
I have migrated my project code on WAS and WPS 6.1.I run a ANT script to build the codebase.
In the EJB module when I build the code using ANT(1.6.1), I am getting the following error:
BUILD FAILED
Could not create type wsejbdeploy due to java.lang.NoClassDefFoundError: com.ibm.ws.ant.utils.WasUtils

I have included the websphere_apis.jar(Which contains ths WsEjbDeploy class) in the shared library and also in the library file of the ejb module.

any help would be great help.
Thanks in advance.
