Thanks Charlie. i made use of the ARGV array..... now, when i am passing 
my parameters from java they are perfectly visible within the run method 
of the thread. But they are not reaching my method in the ruby script 
which is doing all the processing. I am making use of the JSR223 
scripting engine only. The invokeFunction method is the one that passes 
the arguments from java to ruby. One possible reason that comes to my 
mind is the absence of class in my script. is it neccessary to include a 
class in the ruby script?
