Hi karthik9891, have you Configure JDeveloper to Use an HTTP Proxy Server.
I am not much sure but you can give a try
From the Tools menu choose Preferences
Highlight Web Browser and Proxy
Configure JDeveloper to Use an HTTP Proxy Server with these settings
Host Name - www.xxxxxxx.com
Port Number – 80
Exceptions – Add these exceptions to the machine name already listed: |*.oracle.com|*.peoplesoft.com|*.jdedwards.com|*.mlab.jdedwards.com
