thank you all so much for all the help
i had installed java on the d: drive and the system drive is c:
java installation would create a java folder in c: as well even if we install java on any other drive, i placed the comm.jar, the dll file and the properties sheet in the lib and bin directores on the system drive and things worked fine
this forum is excellent with good response from the users, i am using this for the first time and its very knowledgable, one can learn a lot if we browse through the various queries posted on tis forum...
well now i am planning to
test it on a network and see how the comm api behaves...
thanks again....
