Cannot seem to get browser plug-in to work with WebDriver & Jenkins

Hi all,

I've been troubleshooting this day and night and haven't been able to find a way to make this work.  I will try my best to explain our set up.  This is what we are using:

• Jenkins 1.509.3 running on Linux
• dynaTrace 5.5.0.5562
• Jenkins slave 1.509.3 running on Windows Server 2008
• Firefox 20.0 with dynaTrace Browser Agent 5.5.0.5226 for Firefox
• selenium-java 2.37.1
• dynaTrace dtAutomation 3.5

I have a Firefox profile called 'Selenium' set up on the Jenkins slave server running Windows.  The browser plug-in is enabled and connected using this profile and I can see the agent connected to dynaTrace with the Agent name: Browser_Selenium_FF

In the code that calls the WebDriver, I have the following:

ProfilesIni profile = new ProfilesIni();
FirefoxProfile ffprofile = profile.getProfile("Selenium");
driver = new FirefoxDriver(ffprofile);

Here is where it gets interesting.  If I'm logged into the Windows Server (Jenkins slave)and launch a build manually from command line, the WebDriver will get called and Firefox will appear on my screen and the browser agent will connect properly.  I will see the agent show up in the Agents Overview.  This is good.

However, if I were to launch the build from Jenkins, which will in-turn call the Jenkins slave to run the build, I will not see the agent show up in the Agent Overview when WebDriver is called.  I'm almost convinced that the browser-agent doesn't even load for some reason.

Have even tried installing a 'command-line plugin' for Jenkins that will run the maven command directly instead of through the maven Plugin but it still didn't work.  Not sure why it would work when manually running the build and not via Jenkins.

Has anyone encountered something like this before?  Or have any suggestions how to go about resolving this?

Thanks.
