I understand that, in fact the SRW WSDL uses complex types, so I am
creating an actor that will do the necessary steps and possibly use the
Explain operation to gather information about the indexes.
This clarifies the situation.

I am just getting started on this, so I will gain more experience
working on it...
For now, I managed to compile the SRW proxy using the original bindings
fro SRW and the Axis 1.1 included in Kepler, but these generate some
error when run in Java 5 (they work fine with java 1.4).
