The idea is you build a Java class that does the heavy lifting. It connects to the Web service, makes the SOAP query, gets back the data and parses it, making the contents available through Java methods.
You can build this and create a main() class to call your class and test it, all outside of IPIVR.
Once it is all working and tested, you can encapsulate your class in a JAR, and use the Document editor in CRS to upload the JAR and register it. Now IPIVR can "see" the class and the methods through reflection.
In the Expression Editor, you can instantiate your special class and call its methods. You can then pass back values to your IPIVR scripting.
This is not particularly trivial. The Expression Editor document provides guidance, but you have to be pretty savvy to figure out how to call a custom class. You can experiment with a simple Java class in a JAR to see how it works.
As you can see from this outline, your Java skills have to be pretty fair to make this work. But the potential is there.
