Hi Sourabh,
Please check two things -
http://<server>:<port>/resources/sap/ui/core/library.js
if this looks correct which means you can see the library in browser then please use "/resources/sap/ui/core/library.js"instead of
https://sapui5.netweaver.ondemand.com/resources/sap/ui/core/library.js in index.html
http://<server>:<port>/sapui5/resources/sap/ui/core/library.js
if this looks working change the same in index.html as /sapui5/resources/sap/ui/core/library.js
in index.html
deploy the application and check again.
Regards
Jeet
