238015 - Java applet cannot call JavaScript function even though JavaScript and Applet share same origin

Status: RESOLVED DUPLICATE of bug 146458

(Core Graveyard :: Java: Live Connect, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7a) Gecko/20040219

On the page listed above, you should see a message appear in the status bar div
saying connected and a clock should tick every second or every other second as
messages are received from the Java applet.

If I serve the page from static.espn.go.com it doesnt' work in mozilla.  The
applet and the javascript file containing the method that the Java applet is
calling (via JSObject) are both being served from the same host
(caster.espn.go.com).  If I serve the page from caster.espn.go.com, though, it
works fine.

according to the OJI page I found here:
http://java.sun.com/j2se/1.3/docs/guide/plugin/security.html

the browser should only check the origin of java applet and javascript.  This
page works in Safari and IE...

You can see it working in Moz at http://caster.espn.go.com/sujal/caster/test.html .

Reproducible: Always
Steps to Reproduce:
1. Go to URL above
2. Watch
3. Nothing will happen (should see a clock and a message saying "Connected to
ESPN RealTime")

Actual Results:  
No change on the page.

Expected Results:  
You should see a ticking clock (though may not be every second) and a message
saying "Connected to ESPN RealTime" 

It seems the browser is doing an additional security check to make sure that the
page origin is the same as the javascript.

This exact bug is listed as being fixed in the 1.7b release notes... so this is
a duplicate.

Thanks for the quick response.  The download pages need to be updated... nothing
mentions the 1.7b release on the front page, but I realize it was just released
yesterday.

Great work, thanks guys.
