    I hadn't heard that. The only things I saw (from Microsoft though, probably biased in their favor) made it sound like it didn't have enough of a user base to continue supporting it. But that makes a lot of sense.

      I came across an experimental tool named XMLVM, which as claimed can convert the compiled .NET assemblies into Java byte code and vice versa. This makes me thinking why can't Microsoft include Java into the .NET run-time support...

      Why would you like to do that? There is nothing which Java can offer on the language level...well there are some points, like the "throws" declaration which forces you to catch possible exceptions. I do not see any added value on adding Java to the languages for CLR. (except the fact that it is so popular). On the other hand it would be great to write software in C# which would run on JVM... Or let's just wait till the release of Java 8 which will offer some good language stuff (2013...maybe) - than I will happily code in java...maybe

        I wouldn't hold your breath - all their good engineers fled shortly after Oracle took over.

          Great idea. I'm currently linking a Java project into .Net, and I think we need more badly documented, slow running stuff with ugly interfaces in the .Net world.

              Totally agree Being forced to use Java in Eclipse after coding in VS2010 was a nightmare. All that setting up ENV variables JAVA_HOME etc drives you nuts! And the stuff out there in the public domain is soooo amateur looking. BUT (and it's a big one) the reason enterprise Java is used a lot is that it can run on UNIX - that and it's not C++ (which I'd also rather use than Java...)

                Wasn't there a fair bit of litigation in the past regarding just this thing? I would love to at least dump Eclipse and move on to Visual Studio. And dump Java too. Java is proof that after over 55 years of mainstream language development (Fortran came out in 1956) we haven't got very far. A real productivity killer.

                  I fear "enterprise Java" is the same myth like NFO: everybody knows it, but nobody seen. :) Currently .NET has everything to build any scale applications. Who care about "enterprise Java"? People just use stuff most handy in their company - a whole MS chain, from Server/Exchange/SQL till WinXP/Outlook.

                    Agreed But the UNIX problem doesn't go away. I work on a lot Govt stuff and apart from the odd breath of fresh air, it all runs on UNIX - hence no C# dev - it's all done in Java. If there was a reliable solid MSIL VM for UNIX we could truly wave goodbye to the mess that is the Java programming environment....

                      I think is not necessary. In .NET already exist a imitation ( C# ) and i prefer don't to see the microsoft world expand more.

                          I recently started working in a Java project and it is surprising how much functionality .NET developers have available since .NET 3.5 that does not exist in Java.

                            Correction... You are referring to J++ and they were not taken to court over J++. They were taken to court over the "Microsoft Virtual Machine". Without the Microsoft Virtual Machine, J++ was rendered useless as a technology. Microsoft later introduced J# to try and sway Java developers and their source code over to the .NET platform. There was not enough end user support to continue the J# project so they let it go. I think this was a big mistake. You don't close your door to those who might want to convert and join your "file".

                              Probably because C# and Java are effectively identical, C# is just a more mature language (even though it's not older). If you know Java, the only thing you need to learn from there is how underlying structures differ at compile time (generics, etc), linq, lambda expressions and the .NET namespaces that don't exist in java. As others have mentioned there was J#, but even sans the legal issues what's the point? If I want to write Java I'll fire up STS.

                                I wish Java was dead, but it isn't. I code our web site in C#, but I'm forced to use Java for proprietary programs for our shiny, new Oracle DB and EBS implementation. C# is, as you say, far superior to Java: less overhead, clearer syntax (e.g., I love the way you write public properties for C# objects so that you reference them in code as if they were primitives, and not Getter and Setter functions), etc.

                                If goto is so bad, try writing an Assembly program without JMP.

                                  Yeah, this is what happened. Often times, when MS gets its hands on a technology it adds special hooks in for functionality it desires, and in doing so sabotages or takes over that technology as many people come to rely on these hooks. Sun didn't want Microsoft confiscating Java from them, and I don't blame them. I've always viewed the creation of .Net as Microsoft's acknowledgement that Java belongs to Sun and if they want to do it their own way, they have to start from scratch.

                                      The problem is less technical and more religious. The degree of anti-Microsoft hatred with so many Java programmers shares much in common with various religious conflicts. Logic and reason take a back seat to intense loyalties to Java (usually mixed in with the same feelings on Linux, Apache, et al) and villianization of Microsoft. The vitriol I've heard and read from the Java side has been often and intense. To a lesser degree, you see the same thing with a few "Softies" towards Java/Linux/Apache/etc. No matter how well Microsoft improves a programming technology for the "middle of the bell customer-programmers, it will be rejected by the other side. And contrary to some posts, .NET was not created as a response to the Sun Java lawsuits. .NET was already underway, with VB.NET and C# (late 1990s), before the lawsuits were settled. As I remember, back in 2000 when I got my first Visual Studio.NET beta, VB.NET was a bit more "ready for prime time" than C# was, but by the actual release, C# was much improved. That leads me to believe that .NET was the basis for 2 things at the time: Moving from a partially OO VB6 to a fully OO VB7; and having a platform where the languages are syntactic sugar over a common runtime so developers of most languages would have one common and powerful development tool. How much C# was a reaction to Sun's intransigence only someone on the original .NET development team could answer.

                                        They use XSL transformations for the program transformations? :omg: :omg: :omg: That sounds REALLY painful for non-trivial transformations. Also, it looks highly incomplete, especially the supported class libraries. If you just want to run Java byte code on .NET, take a look at IKVM[^] instead. Also, read the IKVM blog[^] if you want to get an idea of just how complex this is - the IKVM author is frequently running into trouble with either Java or .NET not working as documented in some corner cases.

                                        a) It's a HUGE effort to get right (see above) b) Patents. Microsoft started .NET because they got sued when trying to improve Java, remember?

                                        Shouldn't the word "improve" be in quotes? I think that there is a matter of opinion there. I have used Java. I like it a lot. I like Swing and RMI, and the concise syntax. I am now mostly using .NET, C# and also VB.NET. I like .NET a lot also, particularly C#, which is very similar to Java. There are some things I like better about C# over Java, but there are also some things I like better about Java than C#. Of course Java does run on more platforms than Windows.
