FW: Java FreeBSD Alpha

Dear All,

I received the message below from Roberto de Iriarte. If you are interested in Java on FreeBSD/axp, you will find it highly informative.

 You can't have everything.  Where would you put it?

Hi,

    Casually, i read your message to freeBSD-java, as i am not suscribed 
to that mailing list (i should be, i know....) I am one of the ones that 
got Compaq's Java2 for Linux running under FreeBSD-Alpha.

    First, some caveats.

    It is slow. Compaq's JIT will not work under FreeBSD, and it seemed 
to me that the effort needed to make it run was not worth it (see below)
    Installation is painfull, you'r most likely going to need an Alpha 
running linux for a while.
    I'm rather dissapointed on the quality of Compaq's J2SDK for Linux, 
the memory footprint is LARGE!. Running under native Linux, i was unable 
to run the VolanoMark Benchmark with the native JIT, even with 1 GB of 
ram (and it ran painfully slow with the classic VM).
    This makes it rather useless for runnig server side Java Apps.
    Of note, this behavior has also been noticed on Tru64 4.0F
    Of note, this benchmark runs on my 192 mb equipped notebook (ia32) 
with no swapping et all..

    2.   How to proceed (From my own archives)
    2.1    You'll probably want to get a newer lesstif ...
    2.2   I can send you prebuilt libraries to spare yourself step D) if 
you lack a Linux-Alpha machine (or just for convenience)

    Regards,
    Roberto

    P.S Feel free to crossport this to FreeBSD-Java
