I am in contact with a student who is looking for a Masters (MSc) project in the area of Java, web services, and SOAP. The project will last for 3 months.
One interesting possibility I have already suggested would be to look at how best to encapsulate the SOAP-specific pieces of Axis so that other XML protocols could be plugged into Axis. An interesting possibility would be to use Aspect Oriented Programming if SOAP turns out to be a "cross-cutting" concern rather than a relatively separable subsystem. Are there any other potentially suitable projects? He is very keen and Axis could benefit from this kind of effort. Just writing some code would not be suitable, I'm afraid. Glyn
