Bait and Switch? GlassFish v2 and Sun Java System Application Server 9.1
By pelegri on Sep 28, 2007
Our SPECj AppServer 2004 results (SPEC, TA entry) prompted Bill to write about Sun's Conflated Benchmark. You should also read other opinions (, , ) but I want to address Bill's assertion that "there are significant differences between..." GlassFish v2 and Sun Java System AppServer 9.1.
There are NO differences between the run-time JAR files used by GF and SJS AS; the daily builds create these JARs and from there produce several distros with different installers and packaging configurations - check Kedar's writeup. We Productize in the Public and only create a branch to provide Commercial Support.
Different distros include different additional components. For example, the GFv2 distro includes JDBC drivers for Derby, while some SJSAS distros also include Data Direct drivers (free right-to-use - used in the Submission) and HADB. John tried to capture all the relevant details in this FAQ page; let us know if it does not address your questions.
