Active-Active Configuration

I received a comment on one of my previous posts asking how to run a test class using SpringJUnit4ClassRunner from normal application code (i.e. within a main method). I'll admit, I didn't know how to do this, but my interest was piqued.

Today I made some commitments to present some "lightning-talks" on .NET topics for my local .NET user group. I may be giving some discussions on C# basics, HTML5 topics, LESS(CSS), and JavaScript. Like many others who are working in the presentation/evangelism circuit, I feel that this will help force me into showing off some talents that I do have and learning some things that I currently don't know. Follow the Evansville .NET User Group homepage for more details.

In my current project, I have classes which are modeled like the following. At some point, a method like getReturnTypeForGetId() is called on classes A and B . Calling the method with A returns Integer as expected, but B returns Serializable . What am I missing here? Am I getting bitten by some heinous erasure thing, or am I just missing out on some sort of generic context-clobbering? EDIT: Adding an over-ridden getId() method to B fixes the problem, but I would still like to understand what I am running into. I've also asked this question on stackoverflow. import java.io.Serializable ; public class WeirdTester { static interface Identifiable & lt ; T extends Serializable > { T getId (); void setId ( final T id ); } static abstract class BaseEntity & lt ; T extends Serializable > implements Identifiable & lt ; T > { private T id ; public T getId () { return id ; } ...

In doing some investigation for doing contract-first development for web services on .NET, I ran into the wsdl command-line tool. Unfortunately, I was unable to find its equivalent in the MonoDevelop IDE. I finally did some digging around in the terminal and found the MonoDevelop command-line tools at: /Library/Frameworks/Mono.framework or /Library/Frameworks/Mono.framework/Versions/current/bin .

I'm setting out to learn .NET and get some experience creating a non-trivial project. Microsoft does provide Express (free, Windows-only) editions of the Visual Studio application in a few flavors as well as basic version of IIS with ASP.NET and SQL Server. But, since my current personal development environment is a MacBook Pro (OSX 10.6.7), getting started with development on .NET can actually cost money (mostly due to the Windows tax) . The primary development tool for .NET developers on non-Windows systems seems to be Mono with MonoDevelop . The latest stable release of Mono (2.10.1) supports much of the functionality of the .NET 4.0 platform and some portions of Microsoft's extended .NET eco-system: F#, IronRuby, IronPython, ASP.NET MVC(1, 2, and portions of 3) . The latest beta build of MonoDevelop (2.6 beta 2) provides a lot of support for developing applications using C# and the rest of the CLR. I'll be using these in the coming months to do some experimen...
