Either WSDL or wsimport and wsdl (mono) are horribly broken
EDIT I started off with the example given below, but I have now: Tried the example from the W3C spec.

Tried the mono generator wsdl to see if wsimport was to blame. It gives an equivalent error. S...

Comparing ASP.NET MVC and Grails for a new project.
Greetings, everyone. I consider myself to be an intermediate developer, but, to be candid, probably closer to novice than expert.

Java - Power Set construction, ordered by set size, lazy
I need to construct the power sets of a set, lazily, by smallest size first. I have a working class+algorithm (see below), but I feel like perhaps it's crazy, because it seems waaaay too elaborate.
