java version "1.3.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_01)
Java HotSpot(TM) Client VM (build 1.3.0_01, mixed mode)
A simple signed extension that installs correctly when the user chooses "grant
this session" fails if the user instead chooses "grant always". The console
indicates that the user denied the download.
The test case is a simple applet with a subclassed label in an optional
package. It's all basic Plug-in stuff.
sources:
save the following to Bug.java
import java.applet.*;
import java.awt.*;
import javax.swing.*;
public class Bug extends Applet
{
public Bug()
{
initGUI(this);
}
protected void initGUI(Container c) {
c.setLayout( new FlowLayout( FlowLayout.CENTER ) );
add( new MyLabel() );
}
}
save the following to MyLabel.java
import java.applet.*;
import java.awt.*;
import javax.swing.*;
public class MyLabel extends JLabel
{
public MyLabel()
{
super("this is MY label");
}
}
compile each and put the resulting classes in Bug.jar and ext.jar respectively,
using the following manifest info:
bug.mf
Extension-List: myExt
myExt-Extension-Name: com.moi
myExt-Specification-Version: 0.5
myExt-Implementation-URL: http://localhost/bug/grantAlways/ext.jar
ext.mf
Extension-Name: bug.grantAlways.myExt
Specification-Vendor: Moi
Implementation-Vendor-Id: com.moi
Implementation-Vendor: Moi
Specification-Version: 0.5
Implementation-Version: 0.5
sign ext.jar and deploy.
I placed all files (including the following html file) at
http://localhost/bug/grantAlways/
bug.html is as follows:

Make sure ext.jar isn't in the Plug-in's lib/ext/ and run the html. When asked
about downloading ext.jar, choose "grant this session" and observe that
everything works fine -- ext.jar is downloaded and installed and the applet
runs.
Remove ext.jar from lib/ext/, nuke all browser sessions and try again. This
time, choose "grant always". Download fails (and the applet fails to run).
Here's my console log:
