"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

first we must know what is the
org.muos.management.managementSupport
since most of functions are from it and the rest is documented.

//Looks like you got a web service with the following address
String serviceLocation = "http://localhost:8080/axis2/services/TEService";

//ManagementSupportFactory class looks like a utility class to connect to that Web Service ^ returns you a stub to call methods on that Web service
supporter = ManagementSupportFactory.getManagementSupport(serviceLocation);

// The following piece of code  along with all other subsequent similar code demonstrate/test a business method call to the above mentioned web-service,
Each call is enclosed in a separate try-catch loop, this will ensure that the program will continue even if any of the calls fails.
