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

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:

Loading test.com Exception in thread "AWT-EventQueue-0" java.lang.Error: Unresolved compilation roblem: Syntax error on token ""web"", delete this token at webloader.loadcode(webloader.java:11) at web$1.actionPerformed(web.java:46) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Sou ce) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEventImpl(Unknown Source) at java.awt.EventQueue.access$200(Unknown Source) at java.awt.EventQueue$3.run(Unknown Source) at java.awt.EventQueue$3.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(Unknown Sou ce) at java.security.ProtectionDomain$1.doIntersectionPrivilege(Unknown Sou ce) at java.awt.EventQueue$4.run(Unknown Source) at java.awt.EventQueue$4.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(Unknown Sou ce) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)

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.

    "Error: Unresolved compilation problem:": You're trying to run code that won't compile. Never do this. Instead try to compile it first, and then if still confused, show us the compiler's error message, not that of the JVM. Commented Dec 8, 2012 at 12:27
  • There is no compiler error, Commented Dec 8, 2012 at 12:29
  • Even the error from above tells you what's wrong; you're using a variable called web, which is not declared (as far as I can tell). Commented Dec 8, 2012 at 12:30
  • JAR export finished with warnings. See details for additional information. Exported with compile warnings: browser/src/updated.java Exported with compile warnings: browser/src/Checkupdate.java Exported with compile warnings: browser/src/web.java Commented Dec 8, 2012 at 12:31

    That "proper grammar" is quite important if you are asking volunteers to help you. We usually appreciate the effort you put in to make it easier to understand your code, especially when you're asking for our effort to help you. It's not too much I don't think for us to ask you to clean this up and make your code comply with standards. Commented Dec 8, 2012 at 12:48

I was trying to access the file wrong.

Correct code:

import java.io.*; import java.net.*; import java.util.regex.*; import javax.swing.*; public class webloader { static JComponent page; public static void loadcode(){ JEditorPane jep = new JEditorPane(); jep.setEditable(false); try { jep.setPage("http://(server):(port)/" + web.url); } catch (IOException e) { jep.setContentType("text/html"); jep.setText("<html>Could not load webpage</html>"); } JScrollPane scrollPane = new JScrollPane(jep); JFrame f = new JFrame(web.url); f.getContentPane().add(scrollPane); f.setSize(512, 342); f.show(); } }
