Thanks for the response Kurtcebe and Deepak.
The total size of WEB-INF is 33MB, of which lib contributes about 20 MB,Shared Library is already created and referenced.what is the minimum set of Files I need to provide at the time of deployment AFAIK web.xml and WEB-INF/lib and WEB-INF/classes referenced inside web.xml are mandatorily required at the time of Deployment, Rest of the Files I will copy to respective directories post Deployment of war Please let me know if there is any problem adopting this approach.
