soapui acessing property from property file
===

I want to load properties from property file as explained here http://www.soapui.org/Scripting-Properties/working-with-properties.html. I am using testrunner.sh to run the test.
I want to do something like `./testrunner.sh -PServiceEndPoint=${serviceendpointvalue} sample_soapuitest.xml` but its not working. 

serviceendpointvalue has been defined in properties.txt.
I modified JAVA_OPTS in testrunner.sh to include properties.txt.

Has someone tried this? Any sugesstions?
