php-java-bridge-users Mailing List for PHP/Java Bridge

Hi all,

I'm getting an OutOfMemory exception when executing a number of commands over the same PHP/Java Bridge connection....

We are running Java as a standalone process (simply run with "java -jar JavaBridge.jar SERVLET:9090 3 JavaBridge.log") and are accessing from PHP running inside Apache.  All on Windows, although we'll be testing on Linux once we get past this issue.

The code on the PHP side is:


$obj = new Java("our.java.Object");
$obj->returnMyArrayResult($arg1, $arg2);
@java_reset();

which gets called repeatedly within a loop.

The error is:


Apr 14 15:52:25 VMBridge FATAL: OutOfMemoryError

I've seen a number of threads talk about OutOfMemory problems, but no solution... I also saw the "How does the bridge handle OutOfMemoryErrors?" section in the docs, but no help.

My guess is that the JavaBridge class is holding onto all of the Java objects returned to PHP (even though java_release() is called in PHP) and that's what is causing the problem?  Also, looks like maybe JavaBridge.recycle() is the function we eventually want to get called?? Just guesses, though.  

A few questions too:
    1. Any way to release an object after finished with it on the PHP side?
    2. Any ini flags (java.persistent_connections=Off, for example) that could help clear the JavaBridge cache?  

Thanks for any thoughts/comments!

Hi,

> Caused by: java.io.IOException: /ressources/ldap.properties not found

create a jar file which contains "resources/ldap.properties" and copy the jar file into the
library path (either ~/lib or ...jre/lib/ext).
