Teradata Plug-in Eclipse Webservice Creation

I am able to create a webservice using the iBatis SQL Map/Webservices wizard but I am unable to to figure out how to pass in multiple parameters to invoke a method. (Currently, I can only input one parameter- department ID for example). In addition I also would like to know how to return more than one result from the webservice. I get an error message that saying the service was expecting 1 result but found 110 for example. 

Any advice would be greatly appreciated!
