Krasimira and Ravi Maheshwari,
Thanks for your response.
I did the following steps to deploy the war file:
1) Download NWDS and installed NWDS. Netweaver application server is configured from Window =>Preferences=>SAP as Java in NWDS.
2) Created Dynamic web application. Copied all the files of JSP, CSS, images and servlets along with required libraries in the web application.
3) Created Enterprise Application Project in which added the above web application as Java EE module dependencies.
4) Deployed Enterprise Application Project as Run as => Run on Server option.
The web application is deployed in NetWeaver and working fine as expected.
Thanks,
Raman N
