Thread: Java Shared Libraries

i'm looking construct , interface 1 program (the aladin image server) can controlled scripting language (idl). fortunately, hard work has been done me , have (mostly) ready use suite of software handle it. rub developers of package have used idl's java bridge, , know absolutely nothing java. setup rather straight forward (from readme):

before being able use api, need configure idl java bridge :

* create new file $home/.idljavabrc following line :

jvm classpath = $classpath:$home/jar/aladin.jar

property tell idl find needed java classes

* create environment variable called idljavab_lib_location , pointing jvm shared library used. instance, .tcshrc file may have following lines :

setenv java_home /usr/java/jdk1.5.0_04
setenv idljavab_lib_location $java_home/jre/lib/i386/client

easy enough until last steps. i'm not sure find jvm shared library. it's not under /usr/java, there's no such directory. have found /usr/lib/jvm contains

java-1.5.0-gcj-4.4
.java-6-openjdk.jinfo
.java-6-sun.jinfo
java-1.6.0-openjdk
java-6-sun
java-gcj
java-1.5.0-gcj
java-6-openjdk
java-6-sun-1.6.0.24
java-gcj-4.4

i've followed few of these through ./jre/lib/amd64/ haven't yet found 1 containing "client."
i'm running lucid on 64-bit machine (using 32-bit version of idl 7.0, if helps). know best local equivalent /usr/java/jdk1.5.0_04/jre/lib/i386/client is? also, if explain of 10 java-x.x links are, , if need 10 of them, i'd appreciate it.

cheers,
dave

first...unless using shell tcsh...your environment variables set in .bashrc in /home/username directory.
