Executing Selenium tests from Jenkins by calling Ant

I have an ant script that runs some Selenium tests. This works great when running from Windows and also in the Putty bash terminal as user Jenkins

, since the required one is vncserver

started by the user Jenkins

previously and the variable is DISPLAY

set to :43

, I am calling the same ant script on the Jenkins CI server. The environment variable is DISPLAY

configured in the Jenkins web interface for :43

too. The error message I received looks like this:

[junit] Setting selenium logging level to: FINE
[junit] org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7056 after 45000 ms. Firefox console output:

This message is very similar to the one I received when it vncserver

was started by another user and then by someone who started tests. However, this is no longer the case as I double-checked that both the tesorunner and VNC are running Jenkins

.

This is a Solaris server, if any details are needed to help me ask.
