[Php-java-bridge-users] how to pass env variables at jvm startup

[Irfan M. <irf...@gm...>]

how to pass env variables at jvm startup? i need to pass some other
environment variables to the vm.

i am using gentoo with apache2 and php5; if anyone knows where the jvm
gets initialized and started so that i can set some env variables that
will be real helpful.

right now when apache2 is started the php-java-bridge is started with
the parameters specified in the java.ini. i just need to find out
where and how the jvm is initialized.

thanks a lot.

when the RunJavaBridge executable exists in the php
extension dir it will be called instead of java,
please see the "java command" from phpinfo() for
details. 

On RedHat Fedora the following could be used:

# rename RunJavaBridge
mv /usr/lib/php/modules/RunJavaBridge \
   /usr/lib/php/modules/RunJavaBridge.bin

# create a custom RunJavaBridge script
cat >/usr/lib/php/modules/RunJavaBridge <<\EOF1
#!/bin/sh
# This is a custom script which calls the JVM
# with additional arguments.

$java=$1; shift
$args="$@";
$myArgs="-Dphp.java.bridge.threads=30";

exec /usr/lib/php/modules/RunJavaBridge.bin \
     $java \
     $myArgs \
     $args
EOF1

# make our script executable.
chmod +x /usr/lib/php/modules/RunJavaBridge

(The above example calls the saved RunJavaBridge.bin
because it still carries the javabridge_t security
context. If you don't have Security Enhanced Linux or
if you have tagged your RunJavaBridge script with
javabridge_t, you can remove the old RunJavaBridge.bin
and call java directly.)
