[PHP-DEV] persistent java virtual machine under PHP

[Maróy Ákos]

Hi,

I'm trying to use the PHP / Java integration (the module in ext/java). My problem is that the Java Virtual Machine is thrown out regularly by the PHP engine.

What happens is that the function jvm_create() gets called regularly when requesting new pages using the Java extension, from the function java_call_function_handler():

if (!JG(jenv)) jvm_create(TSRMLS_C);

It seems that JG(jenv) gets to be 0 every once in a while. One problem is that on none such occasion is jvm_destroy() called, which could lead to resource leaks.

What I'm looking for is that the JVM would not be discarded on a regular basis, but it would remain persistent. Unfortunately I can't find the mechanism that removes it (so as to disable it).

I was looking at the documentation for extending PHP, especially at http://www.php.net/manual/en/phpdevel.php#phpdevel-addfunc-reslist
Maybe this is the way to go? If so, can someone elaborate on the use of this functionality? I can't really grasp how to use this based on the description there (i.e. what does 'type of resource' mean, etc.)
