I'd like to build a small SOA application to get started on this kind of software development. I'm reading a lot about WSSF and it's advantages to help bould SOA applications but I don't know what should I do for the front end of the application. I was thinking on WCSF but it uses MVC pattern and I'm going for SOA...should I still use this factory?

Another huge doubt is about Data Acces Layer... should every web service be in a separate WSSF project with its own Data Access or there should be a common Data Access for every web service in a complete diferent dll? or maybe, I should develop all the web services for my application on the same project...

As you can see, I'm very lost with all this and I'll really appreciate some help. Thanks!
