Any advice on going about performing a custom Jetty upgrade? The Openfire source build tree lib dir contains the Jetty libs. The 6.1.x reported by Openfire’s Admin Console suggests a customized source build.
Well, anyway the Jetty README.TXT has some good advice:
The Jetty build is rather large, because it bundles many optional
Jetty depends ONLY on a jre 1.4 runtime and the three jars found in
the top level of the $JETTY_HOME/lib directory:
For small foot print applications, these three jars can be
trimmed of excess classes - we will soon automate generation
of such minimal assemblies.
The jars found in the subdirectories are all optional:
jsp-2.0/*.jar (depends on java 2 (jre 1.4))
jsp-2.1/*.jar (depends on java 5 (jre 1.5))
The start.jar includes all these options if they are
left in the lib subdirectories.
The start.jar will also select the version of JSP to
use based on the version of the jre available.
