Service Method Invocation

As we have seen, the abstract representation of method signatures is a key element in XMLbroker. Each service when deployed will be attached a formal signature--devised from the Java interpretation process described above. Whenever a SOAP request is received, the interpretation of the message leads to an actual signature. A Java method call is then prepared and executed (c.f. Figure 2.2) by reconciling the formal and actual method signatures.
