Java: how to handle/parse incoming HTTP requests?

Question

I would like to receive parameters via plain text and http requests. The data is coming in, but I'm stuck with processing it correctly.

Here is some pseudocode of what I would like to achieve:

// ...
String input = in.readLine();
if (HttpHelperClass.isValidHttpRequest(input)) {
    // process http request
    MyHttpRequest = HttpHelperClass.processInput(input);

    if (MyHttpRequest.isMethod(HTTP_METHOD_GET)) {
        String name = MyHttpRequest.getParameter('name');
        String response = HttpHelperClass.buildResponse("Hello " + name, 200);
        out.println(response);
   }
} else {
    // process plain text
}

Does Java have something like this out of the box or can anyone recommend anything?

Thanks in advance!

Your best bet is to use UrlQuerySanitizer. Use this to parse the URL and then call getValue("param-name") to get the desired parameter values.

Thanks for your answer, but I think the UrlQuerySanitizer only covers URLs and their GET parameters. I need to process POST as well.
