Question

import java.io.*;
import java.net.URL;
import java.net.URLConnection;
import java.sql.*;  
public class linksfind{
public static void main(){
    String html = "http://www.apple.com/pr/";
    Document document = Jsoup.parse(html); // Can also take an URL.
    for (Element element : document.getElementsByTag("a")) {
        System.out.println(element.attr("href"));
}
}
}

Guys,
In the above program, while executing I find these errors. How to resolve? I have downloaded Jsoup.jar file in my folder location. What else should I do?

linksfind.java:8: cannot find symbol
symbol  : class Document
location: class linksfind
    Document document = Jsoup.parse(html); // Can also take a
    ^
linksfind.java:8: cannot find symbol
symbol  : variable Jsoup
location: class linksfind
    Document document = Jsoup.parse(html); // Can also take a
                        ^
linksfind.java:9: cannot find symbol
symbol  : class Element
location: class linksfind
    for (Element element : document.getElementsByTag("a")) {

Answer 1

The ones of Jsoup of course.

import org.jsoup.nodes.Document;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Element;

Also see the Jsoup API documentation.

That said, there’s another problem which would only manifest when you got it run: you’re passing the URL in flavor of a java.lang.String instead of a java.net.URL. A String would be treated as plain HTML, not as a resource. Fix it as well:

URL url = new URL("http://www.apple.com/pr/");
Document document = Jsoup.parse(url, 3000);

Update: you just need to ensure that Jsoup libraries are present in both the compiletime and runtime classpath. When using javac.exe and java.exe, use the -cp argument. E.g. to compile it:

javac -cp .;/path/to/jsoup.jar com/example/YourClass.java

and to execute it:

java -cp .;/path/to/jsoup.jar com.example.YourClass
