I'm planning to develop a web-services (SOAP to C++ client) in Java with Metro/Hibernate and front it up with a web-site written in JRuby on Rails, connecting Java modules through JRuby and generally through a database. I already wrote some code and set up everything.
Now, I've heard that .NET 3.5 is really powerful and after some reading I acknowledged that to be true. However, would it make sense to drop this monstrous yet curious hybrid of Java and RoR to switch everything to .NET? Everything: services, database connection (linq for objects), web-front, ajax stuff -- everything in one huge .NET 3.5 solution.
I am also looking to have fun but not as much fun as, say, in C++ for server-side :)
I know that with the power of RoR it doesn't really matter whether it's either side. However, whether I'm all set up for .NET or Java, I still have the feeling I'm doing it wrong and I should just switch to the not-side-I'm-currently-on.
I have a very limited experience with web development, I've only written an ASP.NET web-service once and supported Java web-service so I have a real OCD with the choice of platforms here.
