Front Controller Pattern

This pattern centralizes logic of processing response and request through command pattern and returns the page to be navigated once the request and response are processed.

View HTML in swing Component

Following is the code which displays HTML file in a Swing component “JScrollPane”

import javax.swing.*; import javax.swing.event.*; import javax.swing.text.Document; import java.net.URL; import java.io.*; import java.awt.Cursor; class HTMLDisplay extends JScrollPane implements HyperlinkListener { JEditorPane edit; public HTMLDisplay(String fileName) { edit = new JEditorPane(); edit.setEditable(false); edit.addHyperlinkListener(this);


		getViewport().add(edit);

		File file = new File(fileName);

		showURL("file:"+file.getAbsolutePath());

	}
	public void hyperlinkUpdate(HyperlinkEvent e)

	{

		if (HyperlinkEvent.EventType.ACTIVATED == e.getEventType())

		{

	    		// when a link is cliked page display is differed slightly to ensure

	    		// proper evet dispatch and paint

	    	Cursor c = edit.getCursor();

			Cursor waitCursor = Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR);

			edit.setCursor(waitCursor);

	    	SwingUtilities.invokeLater(new URLLoader(e.getURL(), c));

		}

	}
//******************************************************************************************

// Function Name : showURL(String url)

// Parameter : String url

// Returns : None

//

// Displays the URL passed to it in the JEditorPane, in case of error, shows error message box

//

//******************************************************************************************
	public void showURL(String url)

	{

		Document doc = edit.getDocument();

		try{

				edit.setPage(url);

		}catch(IOException e)

		{

			//edit.setDocument(doc);

			System.out.println(e);

			JOptionPane.showMessageDialog(this, "Couldn't open page : " + url);

			getToolkit().beep();

		}

	}	
//******************************************************************************************

// Inner Class : URLLoader

public void run() { //after PAINT is done if(null == url) { edit.setCursor(cursor); } else { showURL(url.toString()); url = null; // to show normal cursor SwingUtilities.invokeLater(this); } } } }
