从Java上的外部网页获取内容

Question

I have a following EJB:

@Stateless
public class SomeService {
    public String someOperation() {
        ...
    }
}

So, the problem is to get content of external web page (for example http://example.com/some/link/info.xml ) and return it. I need something like this:

String pageContent = SomeFancyLibrary.getPageContent(someurl);

Sorry if this question has been already asked here, but I didnt find any info.

From: https://docs.oracle.com/javase/tutorial/networking/urls/readingURL.html

import java.net.*;
import java.io.*;

public class URLReader {
    public static void main(String[] args) throws Exception {

        URL oracle = new URL("http://www.oracle.com/");
        BufferedReader in = new BufferedReader(
        new InputStreamReader(oracle.openStream()));

        String inputLine;
        while ((inputLine = in.readLine()) != null)
            System.out.println(inputLine);
        in.close();
    }
}
