如何在JSP中检索内容/文件？

Question

I have a question about the JSP. I have a JSON file in the server and the content is like the following:

{ "class":
    {
        "number": 2,
        "student": 
        {
        "name": "Tom",
        "age": 1
        },
        "student": 
        {
        "name": "May",
        "age": 2
        }
    }
}  

when I type the URL (eg 1.1.1.1 ), it will display the content like the above.

And, in my JSP page, I have call this url in order to display the JSON content. However, I don't know use WHAT object/or class to call and retrieve the file.

Does the JSP/Java provide some classes do that? Can anyone help me? Thank you.
