Bug 19379 – WebEx Plugin can't launch application

• Status: RESOLVED
• Resolution: INVALID
• Component: Plug-ins

[Wout Mertens]

I don't really understand how everything ties together, but when I use Safari 3.1 to connect to a WebEx meeting, it just works, and when I use WebKit, it doesn't work.

There is a plugin called WebEx Plugin, which somehow causes the application WebEx Meeting Manager to start. It seems like under Safari it can then pass the meeting details on to the application, but under WebKit it can't, even though the application starts.

The only other thing I could find was the difference in the syslog: (Note that it takes about 1 minute to start the application each time)

That's all I can find, sorry.

Can you please provide a link to the plug-in that you mention, and some information about how to use it to reproduce the problem you describe?

[Anthony Southworth]

To replicate, enter the URL:  http://www.webex.com.

Click on the "View Demo" link.  Enter a name and email address, then click "Join Now".  Webkit will not be able to launch the Meeting Manager plugin.  Works fine from Safari 3.1.1.

Confirmed.

[Wout Mertens]

I really wonder what causes this - I'm beginning to think that it is because of WebKit being called WebKit and not Safari, since WebEx still works in the latest Safari, which presumably had some WebKit updates.

In any case, this bug is blocking me from using WebKit as my only browser. The only way to start WebEx sessions is through a browser other than WebKit.

This is a really old bug and has probably been fixed now.
