[Php-java-bridge-users] Persistent/shared java object in jvm between requests (not sessions)

[<php...@li...>]

Hi.

I'm trying to implement the following: Berkeley DB <-> JNI <-> Java
<-> php-java-bridge <-> PHP.

I would like to have only _one_ persistent Berkeley DB "Environment"
(a class instance) available to every PHP request (so this is not
something session-specific). The idea would be to somehow create an
instance of an object when the Java VM starts up, and then access it
from all PHP requests.

I need to have this common instance for caching, resource utilization
and concurrency purposes.

Is there any way to do this with php java bridge?

Thank you for your time,
Ovidiu Dan,

Hi Ovidiu,

if you control the environment in which the bridge
runs, there are certainly ways to do it.

You could store the singleton in the application store
(see
http://php-java-bridge.sourceforge.net/documentation/PHP-API/html/java_8c.html#doc25).
Please also see the FAQ entry which describes how to
start a persistent JVM.

Since Java 6 RC on Linux, Solaris and Windows, users
can simply double-click on the JavaBridge.war file to
start a persistent JVM once.

Hi.

Thanks for the answer. It looks like it's working now.

To set the instance (only once):
java_get_session()->put("DbEnv", $dbenv);

To read it from every PHP request:
$dbenv = java_get_session()->get("DbEnv");

Thanks,
Ovidiu Dan

Better:

java_get_session("DbEnv")->put(...);
$dbenv=java_get_session("DbEnv")->get(...);

this avoids surprises when you switch to the J2EE back
end.
