displaying html in java (SWING)

**SirAiris** · 12-08-2012, 03:15 PM

I am working on a project of sorts to load HTML files from a server and display them in swing.

Java Code:

import java.io.*;
import java.net.*;
import java.util.regex.*;
import javax.swing.*;


public class webloader {
    public static void loadcode(){
        URL url = null;
        try {
            url = new URL("web"+File.separator+web.url+File.separator+"index.html");
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }
        URLConnection con = null;
        try {
            con = url.openConnection();
        } catch (IOException e) {
            e.printStackTrace();
        }
        Pattern p = Pattern.compile("text/html;\\s+charset=([^\\s]+)\\s*");
        Matcher m = p.matcher(con.getContentType());
        String charset = m.matches() ? m.group(1) : "ISO-8859-1";
        Reader r = null;
        try {
            r = new InputStreamReader(con.getInputStream(), charset);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        StringBuilder buf = new StringBuilder();
        while (true) {
          int ch = 0;
        try {
            ch = r.read();
        } catch (IOException e) {
            e.printStackTrace();
        }
          if (ch < 0)
            break;
          buf.append((char) ch);
        }
        String str = buf.toString();
        JFrame mainframe = new JFrame(web.url);
        mainframe.setSize(800, 750);
        mainframe.setResizable(false);
        JPanel website = new JPanel();
        JLabel webcontent = new JLabel(str);
        website.add(webcontent);
        mainframe.add(website);
        mainframe.setVisible(true);
    }
}

Error:
#5498427 - Pastie
PS. I am quite new to java, so if I seem to be stupid or not know what I am doing, that's because I am.

Displaying HTML in swing (JAVA) - Stack Overflow

I posted it here, got no where.

Java Code:

web.url

on line 11.
You have no 'web' variable.

This code does not compile, so trying to run it is a bit pointless (which is sort of what that error is telling you).

Also, I would recommend actually posting the stack trace and error along with your post.
Many people won't bother going to links.
