A microcall is an XML-dialect used to communicate between a client and a server in a standard and easy-to-use way. The client part is (usually) implemented in Java and consists of a simple POJO that can understand the XML messages returned by the server response to a given call. The server part is only responsible for returning standard and correct messages in response to a given call. The server usually does a lot of work when it receives a call, but from the client standpoint, the server only returns a message explaining the result of the call.
