Running web application on local host

I wrote a web-application which is using java library SOCIAL AUTH for oauth . For this i need to generate a secret with oauth provider like google,twitter .

while generating the key i gave the location of site eg: www.xyz.com . Now these oauth provider are retuning their response at the location www.xyz.com

But i want to test my application on localhost wheather is going fine or not.So while runnning on localhost oauth provider is coming as null .

IS there any way by which i can 开发者_运维问答use do by which i can say my tomcat to take the properties or response from www.xyz.com .So that it ll be able to read the response coming from oauth provider

One trick for these types of situations is to temporarily change your /etc/hosts file (if you're on Linux or Mac) so that www.xyz.com points to your localhost. That is, put the following line in the file:

127.0.0.1    www.xyz.com

Then, when the remote site redirects you back to www.xyz.com, that will resolve to localhost. You just have to remember to comment out this line in /etc/hosts whenever you want to access the real production system.

(You can do the same thing on Windows, but I can't remember where the equivalent of /etc/hosts is on Windows, and I don't have access to a Windows box right now.)
