I Have developed one such basic application employing JEditorPane. The Code is as follows
ReadServerFile.java
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.io.*;
import javax.swing.*;
import javax.swing.event.*;
public class ReadServerFile extends JFrame {
     private JTextField enter;
     private JButton go;
     private JEditorPane contents;
     JToolBar jtb;
     JScrollPane jsp;
     JButton jbLoad,jbUnload,jbDesc,jbFind,jbSave,jbPrint,jbGet,jbGetNext,jbGetBulk,jbSet,jbBrow,jbTrap,jbGraph,jbTable,jbDebug,jbClear,jbStop,jbHelp,jbExit;
     public ReadServerFile() {
          super("Simple web browser");
          getContentPane().setLayout(null);
          int v = ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS;
          int h = ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS;
          Container c = getContentPane();
          enter = new JTextField("Enter file url");
          enter.addActionListener( new ActionListener(){
                    public void actionPerformed(ActionEvent e){
                         getThePage(e.getActionCommand());
          enter.setBounds(25,50,500,30);
          c.add(enter);
          //c.add(enter,BorderLayout.NORTH);
          go = new JButton("Go");
          go.setBounds(550,50,75,30);
          c.add(go);
          contents = new JEditorPane();
          contents.setEditable(false);
          contents.addHyperlinkListener( new HyperlinkListener() {
                    public void hyperlinkUpdate(HyperlinkEvent e){
                         if(e.getEventType() == HyperlinkEvent.EventType.ACTIVATED)
                         getThePage(e.getURL().toString());
          //c.add(new JScrollPane(contents), BorderLayout.CENTER);
          jsp = new JScrollPane(contents,v,h);
          //contents.setBounds(25,100,650,400);
          jsp.setBounds(25,100,700,450);
          c.add(jsp);
          Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
          setBounds(0,0,screenSize.width,screenSize.height);
               jtb = new JToolBar(0);
                    jbLoad      = addToolButton(jbLoad,new ImageIcon("load.jpg"),"Load MIB Module");
                    jbUnload      = addToolButton(jbUnload,new ImageIcon("unload.jpg"),"UnLoad MIB Modules");
                    jbDesc          = addToolButton(jbDesc,new ImageIcon("describe.jpg"),"Description");
                    jbFind          = addToolButton(jbFind,new ImageIcon("find.jpg"),"Find MIB Node");
                    jbSave = addToolButton(jbSave,new ImageIcon("saveresult.jpg"),"Save MIB browser results");
                    jbPrint          = addToolButton(jbPrint,new ImageIcon("printresult.jpg"),"Print MIB browser results");
                    jbGet          = addToolButton(jbGet,new ImageIcon("get.jpg"),"Get SNMP variable");
                    jbGetNext     = addToolButton(jbGetNext,new ImageIcon("getnext.jpg"),"Get Next SNMP variable");
                    jbGetBulk = addToolButton(jbGetBulk,new ImageIcon("getbulk.jpg"),"GetBulk SNMP data");
                    jbSet          = addToolButton(jbSet,new ImageIcon("set.jpg"),"Set SNMP variable");
                    jbBrow          = addToolButton(jbBrow,new ImageIcon("settings.jpg"),"MIB browser settings");
                    jbTrap          = addToolButton(jbTrap,new ImageIcon("trap.jpg"),"Trap viewer");
                    jbGraph          = addToolButton(jbGraph,new ImageIcon("graph.jpg"),"View real time graph");
                    jbTable          = addToolButton(jbTable,new ImageIcon("table.jpg"),"View SNMP table data");
                    jbDebug          = addToolButton(jbDebug,new ImageIcon("debug.jpg"),"Debug");
                    jbClear          = addToolButton(jbClear,new ImageIcon("clear.jpg"),"Clear results display");
                    jbStop          = addToolButton(jbStop,new ImageIcon("stop.jpg"),"Stop");
                    jbHelp          = addToolButton(jbHelp,new ImageIcon("help.jpg"),"Help");
                    jbExit      = addToolButton(jbExit,new ImageIcon("exit.jpg"),"Exit");
jtb.setBounds(10,10,400,60);
c.add(jtb);
          //setSize(400,300);
          show();
     } // end of constructor
          private void getThePage(String location){
          setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
          try{
               contents.setPage(location);
               enter.setText(location);
          catch(IOException io) {
               JOptionPane.showMessageDialog(this,"Error retrieving specified url","Bad url",JOptionPane.ERROR_MESSAGE);
          setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
          } // end of getThePage
          public JButton addToolButton(JButton name,ImageIcon image,String tooltip)
                    name=new JButton(image);
                    name.setBorderPainted(false);
                    name.setFocusPainted(false);
          // name.addMouseListener(this);
                    name.setToolTipText(tooltip);
          name.setMargin(new Insets(0, 1, 0, 1));
          name.getAccessibleContext().setAccessibleName(tooltip);
          name.setActionCommand(tooltip);
                    jtb.add(name);
                    return name;
          public static void main(String args[]) {
          ReadServerFile app = new ReadServerFile();
          app.addWindowListener( new WindowAdapter() { public void windowClosing(WindowEvent e)
          { System.exit(0);} } );
     } // end of Main
} // end of this class
