The recent thread on Oracle problems, combined with some work
I needed to get done, motivated me to try something with
JServ that I've already been able to do with JRun. Surprise,
surprise, it didn't work! Here are the specifics.
When using a thick JDBC driver, the Java runtime eventually
needs to be able to load the dynamic library that implements
the native interface. In Solaris, this means that the JVM
(1.1.7 in my case) will use LD_LIBRARY_PATH to find the
appropriately-named ".so" file. No matter what I try, I
can't seem to get JServ to find that dynamic library.
With JRun it is pretty easy; you start JRun before launching
Apache, so you just make sure that you have LD_LIBRARY_PATH
set appropriately before you launch JRun.
With JServ (1.0b3, which I have linked statically into
Apache 1.3.3), setting LD_LIBRARY_PATH before launching Apache
doesn't work. I haven't yet found a directory where I can copy
the .so file and have it found (which would be of limited
use anyways, since there are bucklet-loads of dynamic libraries
that the native driver depends upon in turn, so ultimately
I do have to find a proper fix to the problem). Using PassEnv
from mod_env doesn't seem to help either.
This exact same code works when tested with JBuilder2 under
windows, and a comparable approach (the JRun example mentioned
above) works under Solaris, so I'm pretty sure I'm trying to
do something relatively sane.
Does anybody have any ideas on how to fix JServ to work with
my choice of LD_LIBRARY_PATH? Please cc me on any replies;
that way I'll get them that much faster, and right about now
faster sounds real good....
