Which Java VM is the best for freebsd 5.4, running gnome2, and firefox?

Both the native jdk14 and jdk15 provide good Java VMs. jdk15 is newer and might be unstable (hasn't been for me). jdk14 is more tested and is the "default" java for FreeBSD on i386.


can you have both versions installed ?
and how do you choose which one of them to use (for instance in mozilla) ?


Yes, you can have both installed at the same time. /usr/ports/java/javavmwrapper makes switching JVMs easy using environment variables, however it doesn't seem to support switching browser plugins. For that you'd probably have to switch the symlink in /usr/X11R6/lib/browser_plugins and restart the browser.



i've just tried it and realised it had already been installed as a jdk* dependency. :)

however, according to the man page, running the following should select the most native and up-to-date version of java:

$ java -version
java version "1.4.2-p8"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-p8-root_21_jan_2006_21_32) Java HotSpot(TM) Client VM (build 1.4.2-p8-root_21_jan_2006_21_32, mixed mode)

however, i've got newer version installed too:

$ cat /usr/local/etc/javavms
/usr/local/jdk1.5.0/bin/java # FREEBSD-JDK1.5.0
/usr/local/jdk1.4.2/bin/java # FREEBSD-JDK1.4.2
/usr/local/linux-sun-jdk1.4.2/bin/java # Linux-Sun-JDK1.4.2.10

how come 1.5.0 wasn't selected in the example above please ??
