When running a Java program from a jar file, I'm wondering if it is
at all possible to use Desktop.browse() to browse a html file inside
the same jar? I'd like to do this to provide online help for my
application. Does anyone have any suggestions?
Try getting the resource's URL in the usual way:
<http://www.devx.com/tips/Tip/5697>
Then convert the URL to a URI:
Desktop.getDesktop().browse(myurl.toURI());
"jar:file:..." URIs seem to work with Firefox, but not Safari.
Failing that, I guess you can always link to your web site or cache the
resource in the local file system.
I can't seem to get it to work. I'm getting an 'Access is denied'
IOException.
C:\t>java -jar test.jar
jar:file:/C:/t/test.jar!/t/test.html
java.io.IOException: Failed to open
jar:file:/C:/t/test.jar!/t/test.html. Error
message: Access is denied.
The problem appears to be the URI. I don' really understand why it
would have the /C:/t/test.jar in it.
I know I tried to do this once before and gave up but I can't remember
why. This would be a really handy feature if I could get it to work.
package t;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.*;
public class test extends JFrame {
public test() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JButton b = new JButton("open");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
Desktop d = Desktop.getDesktop();
try {
URI uri = getClass().getResource("test.html").toURI();
System.out.println(uri);
d.browse(uri);
} catch (Exception e) {
e.printStackTrace();
}
}
});
add(b,BorderLayout.CENTER);
pack();
setVisible(true);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
new test();
}
});
}
}
