I run RQM 4.0.3 on image4, which is a Linux RedHat 6.2 64bits.

I installed Selenium 2.37.0 on image5, which is a Linux RedHat 6.2 64bits with Firefox 3.6.24

I configured the selenium.properties with the classpath entries, as described in:
http://www.ibm.com/developerworks/rational/library/run-automated-selenium-junit-tests/index.html

The RQM adapter and selenium are using this JVM:

java version "1.7.0"
Java(TM) SE Runtime Environment (build pxa6470sr5-20130619_01(SR5))
IBM J9 VM (build 2.6, JRE 1.7.0 Linux amd64-64 Compressed References 20130617_152572 (JIT enabled, AOT enabled)

I launch my TestCase and it fails with:

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

Any suggestions?

I forgot, this is the TestScript class:
