Having just read Andrew Cowie’s recent blog, I wanted to comment but couldn’t find an option to do so there. So here it comes here on my blog instead…

Simply put, OpenJDK is so named because it’s a FOSS version of Sun’s JDK the implementation, not Java, which is the specification. Just because OpenJDK is the reference implementation doesn’t mean it is the specification as well. The equivalent would be calling Tomcat OpenServlet (it being the reference servlet implementation). This also reflects on the comments about the HTTP server being in com.sun. This is because it is part of Sun’s implementation and not part of the Java specification. To become part of the specification requires a JSR and interaction with the JCP which are distinct and separate from OpenJDK. That’s the process that would result in java.net.httpserver (or, more likely, javax.net.httpserver because it’s not an essential part of the core).

I hope that clears things up. I’m really happy OpenJDK has found an interesting alternate use that clearly demonstrates the benefits of the FOSS implementation over the proprietary one, and thanks for blogging on this. Now you should go build IcedTea… ;)

    , for DirectX i am using DirectX9 and VC++ with SP 6 , not able to find the SP3 for that.
    even though SP 6 and DirectX 9 are advance this shows error.
    waiting for your Reply.

    I suggest you do what it tells you to. I don’t run proprietary operating systems and thus have never touched the Windows build.
