This ASP News article sums up how the Microsoft and Sun approaches compare. If .Net manages to become a credible multi-platform environment (who ever used ActiveX/DCOM ports by Software AG?) – through portability or interop – then Microsoft will win all these developers than don’t know Java and don’t care to learn it (or that their employers don’t want to retrain).
Update: Roger Sessions’ comparison of J2EE and .NET is fatally flawed (about a white paper and its critic by Giga).
