Whats wrong with my AppletContext.showdocument?

**catch** · 09-08-2006, 09:29 PM

ive been having a hard time figuring out my problem and i think its time to let this problem out to the world. im trying to call a certain html file to be shown on a certain frame of another html file, after a Java-made button is clicked.

to clear things out, here's the code:

Code:

import java.applet.*;
import java.net.*;
import java.awt.*;
import javax.swing.*;
import javax.swing.AbstractButton;
import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JFrame;
import javax.swing.ImageIcon;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;

public class TestHomeButton extends Applet implements ActionListener {


JButton homeButton;
JPanel panel; 
AppletContextAdapter fetchURL = new AppletContextAdapter(); 

public void init( ) {
setLayout(new BorderLayout( ));
setBackground(Color.white);

homeButton = new JButton("Home");
homeButton.setVerticalTextPosition(AbstractButton.CENTER);
homeButton.setHorizontalTextPosition(AbstractButton.CENTER);
homeButton.setToolTipText("History & Introduction");
homeButton.setActionCommand("home");
homeButton.addActionListener(this);
add("Center", homeButton);
}


public void start( ) {
System.out.print("Applet starting.");
}


public void stop( ) {
System.out.print("Applet stopping.");
}


public void destroy( ) {
System.out.print("Destroy method called.");
}


public void actionPerformed(ActionEvent e) {
try
{
// URL myUrl = new URL("simple.htm");
if ("home".equals(e.getActionCommand( ))) 
fetchURL.showDocument(new URL("simple.htm"),"ButtonResults");
AppletContext.showDocument(new URL("simple.htm"),"ButtonResults");

}
catch(Exception exept)
{
}
}

the code above is good for one button only. i have made a dozen of these but im just testing one button for now to get the solution right.. the other would be later...

here's the (main) html file...

Code:

<html>
<head> <title> SKI group </title> </head>
<body background="bg_fade.gif">

<center><table border="0" cellpadding="0" cellspacing="0" bgcolor="#FFFFFF">

<tr>
<td colspan=11><br></td>
</tr>

<tr>
<td colspan=11><br></td>
</tr>

<tr>
<td width=25><br></td>
<td width=50 align="center"><img src="house.jpg" width=60 height=50 ></td>
<td width=25><br></td> 
<td width=50 align="center"><img src="puzzle.jpg" width=60 height=50 ></td>
<td width=25><br></td> 
<td width=50 align="center"><img src="gears01.jpg" width=60 height=50 ></td>
<td width=25><br></td>
<td width=50 align="center"><img src="maze.jpg" width=60 height=50 ></td>
<td width=25><br></td>
<td width=50 align="center"><img src="peoplemove.jpg" width=60 height=50 ></td>
<td width=25><br></td>
</tr>

<tr>
<td width=25><br></td>
<td width=50 align=center><applet code="TestHomeButton.class" width=120 height=40> </applet></td>
<td width=25><br></td> 
<td width=50 align=center><applet code="TestVariablesButton.class" width=120 height=40></applet></td>
<td width=25><br></td>
<td width=50 align=center><applet code="TestOperatorsButton.class" width=120 height=40></applet></td>
<td width=25><br></td>
<td width=50 align=center><applet code="TestFunctionsButton.class" width=120 height=40></applet></td>
<td width=25><br></td>
<td width=50 align=center><applet code="TestCrewButton.class" width=120 height=40></applet></td> 
<td width=25><br></td>
</tr> 

<tr>
<td colspan=11><br></td>
</tr>

<tr>
<td colspan=12>
<iframe name="ButtonResults" src="welcome.htm" 
width="700" height="500" 
scroll="0" frameborder="0">
</iframe>
</td>
</tr>

</table></center>

</body>
</html>

so, once homeButton is clicked it calls on another html file to be shown inside the iframe... unfortunately, it just didnt work

i am hoping you guys here could help me out and enlighten me...

thanks, in advance

I believe there are many solutions to this problem, if you ask me to program, I would rather use JEditorPane, you can find a sample code along with the Java installer, in linux it is in /usr/java/jdk1.5.0_06/demo/jfc/SwingSet2/ depending on what version you have. In Windows, it is under Program Files then Java ...

**catch** · 09-09-2006, 08:58 PM

i did solve my problem...

Code:

public void actionPerformed(ActionEvent e) {
   try {
     if ("home".equals(e.getActionCommand( ))) 
     getAppletContext( ).showDocument(new URL("simple.htm"),"ButtonResults");
   }
   catch(Exception exept) { }
}

but the page i requested everytime i clicked on any button wouldnt be loaded on the specified frame. anyone would care to help?

Code:

public void actionPerformed(ActionEvent e) {
   try {
     if ("home".equals(e.getActionCommand( ))) 
     getAppletContext( ).showDocument(new URL("simple.htm"),"ButtonResults");
   }
   catch(Exception exept) { }
}

getAppletContext( ).showDocument(new URL("simple.htm"),"ButtonResults");

Na try na nimo og absolute ang path? Ex. C:\simple.htm nya wala gihapon og work?

Sa path man gud nasangit usahay ang mga programmers.

**catch** · 09-10-2006, 03:13 PM

will try inserting the whole path...

but it shouldnt be of a problem since the classes and the HTML files are on the same directory unless i put it somewhere else.

mura madala manang imong gi buhat without using Java...

**cen** · 09-10-2006, 08:11 PM

Code:

public void actionPerformed(ActionEvent e) {
   try {
     if ("home".equals(e.getActionCommand( ))) 
     getAppletContext( ).showDocument(new URL("simple.htm"),"ButtonResults");
   }
   catch(Exception exept) { }
}

ni work ba sa pag-try nimo og absolute path? Pls. reply...

if yes try this...

insert this one --> System.getProperty("user.dir"); // this code returns a string which is the current directory.

example:

getAppletContext( ).showDocument(new URL(System.getProperty("user.dir") + "\simple.htm"),"ButtonResults");

gamit ni nako permi. :mrgreen:

example:

C:\MyProgram
|--------->Sample.jar
|--------->record.xml

Since

System.getProperty("user.dir"); // the parameter "user.dir" returns "C:\MyProgram" string

I often use this code

Code:

props.loadFromXML(new FileInputStream(System.getProperty("user.dir")+"/record.xml"));

Hope it works bro. Goodluck :mrgreen:
