Strange. Derby = server Home = no server capability Business/Ultimate = development incl. server capability ? Arne

Java DB is documented & supported. Is the HTTP server that? Arne

From: http://java.sun.com/javase/6/docs/technotes/guides/net/index.html click on the fourth link in the "API Specification" section. The "Networking features and enhancements" page: http://java.sun.com/javase/6/docs/technotes/guides/net/enhancements-6.0.html talks about that server. Apparently it is meant to stay. --Thomas Pornin

We had a back-and-forth over this a while ago. It's unarguably documented - but it's not clear that it's part of the API (to put it mildly), and not clear that, because of that or otherwise, it's supported. But then, support, schmupport. A decompiler and -Xbootclasspath is worth ten thousand support requests anyway. tom -- unconstrained by any considerations of humanity or decency

As far as I can see, the documentation makes it (relatively) clear that: -- It is distributed with Sun's (Oracle's) implementation of Java 6 and should be present on all Java-6 compliant JRE from Sun. -- It is meant to be used. -- It should continue being there in subsequent releases. -- It is not part of what makes the "Java" API, so that other JRE from other vendors may rightfully claim "full Java support" without including that HTTP server. At no point do they promise that they will keep the API unchanged or at least backward compatible... > But then, support, schmupport.

See: http://download.java.net/jdk6/source/ The HTTP server source code is less than 2000 lines long; it is really small, making it improbable that it is ever removed. --Thomas Pornin |
