How to install Java JRE on FreeBSD with as few dependencies as possible

  • 772

I've been trying to get Java working on my FreeBSD 7.1 server. I just want the runtime, since the JDK drags all kinds of unnecessary dependencies with it, and I just need it to run a jar file periodically. I've installed the FreeBSD-supported diablo-jre, but whenever I try to run it, I get a:

/usr/local/diablo-jre1.6.0/bin/java: 2: Syntax error: "(" unexpected

So what to do?

java freebsd nix

    Ah, I've figured it out. For all this time, I've been trying to run the amd64 version on a machine that's still running i386. Mea culpa.

    So to install Java on your FreeBSD server with as few depedencies as possible:

    • Download the tarball (make sure to pick the one under the tarballs header, and for the correct FreeBSD version and platform) from The FreeBSD foundation's Java downloads.
    • Put the downloaded file in /usr/ports/distfiles/
    • # cd /usr/ports/java/diablo-jre16
    • # make config install clean
    • Be sure to disable all optional components from the configuration screen.
    • Let the installation run its course and be happy :)

  2. file /usr/local/diablo-jre1.6.0/bin/java

    Will probably tell you that java is actually a shell script that sets up an environment and launches the real JRE

  3. I used the last JRE version for Windows, installed in my home directiry under .wine. Then I run java -jar program_name.jar from command line in a shell, and it's OK.

    Program runs perfectly for me.
