getting JSON response from webpage

I don't know a lot about this area so please excuse me if my question is vague or stupid.

I have a webpage which uses javascript and AJAX to display live data. Every few seconds, a request is made and a JSON response is returned and the data on the webpage is updated.

What I want to do is create a program in Java that will basically capture every response and interpret the data. I have found libraries which handle the JSON format already. Howev开发者_StackOverflow社区er, I don't know how to get the response using Java.

So for example, a live news feed. I would like to log the data as it appears.

Thanks

Basically what you need to do is make an HTTP GET request to the page that hosts the JSON. You can do this by using a Java HTTP client. The one in the link is from Apache Commons but I believe there is actually one built into Java that is relatively straight-forward to use. When you make a request, it will return a result object that you can then use to access the response data and information such as response headers, etc.
