Do you want to open an HTML file in a Java application and print its source?

Rendering HTML is a non-trivial task. The best way to do what you're asking is to let a web browser handle that job.

in the line : DocumentRenderer1.print(u);
is should recive HTMLDocument (hich i dont understand how execlly to use)

import javax.swing.text.html.HTMLDocument;
import java.net.URL;
import java.net.MalformedURLException;
import java.io.IOException;
import java.io.DataInputStream;
import java.io.InputStream;

public class PrintHtml {
public static void main(String[] args) {
System.out.println("printing...");
DocumentRenderer DocumentRenderer1 = new DocumentRenderer();

HTMLDocument x = new HTMLDocument();
URL u;
InputStream is = null;
DataInputStream dis;

try {
u = new URL("http://www.walla.co.il");
DocumentRenderer1.print(u);

} catch (MalformedURLException mue) {

System.out.println("Ouch - a MalformedURLException happened.");
mue.printStackTrace();
System.exit(1);

} catch (IOException ioe) {

System.out.println("Oops- an IOException happened.");
ioe.printStackTrace();
System.exit(1);

} finally {



try {
is.close();
} catch (IOException ioe) {

}

} // end of 'finally' clause

}

}

First off
DocumentRenderer DocumentRenderer1 = new DocumentRenderer();
Should be something like
DocumentRenderer dr = new DocumentRenderer();
And
HTMLDocument x = new HTMLDocument();
should be a more meaningful
HTMLDocument doc = new HTMLDocument();
Then you need to learn how to load up the doc from a URL, after which I guess you'd
dr.print(doc);
I've never seen any of this stuff before so I'm just guessing here.

[pelegk1]

i agree about the way variablles should be named
but the actuall problem on :
dr.print(doc);
you didnt help me!
i can't understand how execlly the doc object recives a url
do it can be printed
any idea?

[ray326]

Not without reading throught the API doc on HTMLDocument. That's what I'd recommend you do next.

[pelegk1]

but didnt understand execlly how to do it
