WebEx Works Again in Ubuntu 9.04

I was having trouble getting WebEx to work after I upgraded to Ubuntu 9.04.  After opening a support ticket with WebEx, I finally figured out the problem was with my Java configuration directory.  When I removed that, it started working!

mv ~/.java ~/java_backedup

Here are some more details for troubleshooting:

Here is the error message that I was getting:

The publisher cannot be verified by a trusted source. Code will be treated as unsigned.

Here is the exception stack trace from the details button:

Here is another troubleshooting tip: Adding WebEx as able to install addons:

In Firefox please open the Firefox Options

Click on Security

Click on Exceptions (located next to Warn me when sites install add-ons)

In the exceptions please add *.webex.com to the Allowed list.

Click OK on all open boxes and restarted Firefox.

This post, help me find the issue.  They mentioned the trusted.certs file from the ~/.java/deployment/security directory.  Their solution was to delete both the trusted.certs and auth.dat files from the directory.  I didn’t remember anything that I had configured in that directory so I just backed up and delete the whole directory:

mv ~/.java ~/java_backedup

I hope all of this information helps.
