echo 'Java vendor=' . $system->getProperty('java.vendor') . '<br />';
echo 'OS=' . $system->getProperty('os.name') . ' ' .
             $system->getProperty('os.version') . ' on ' .
             $system->getProperty('os.arch') . ' <br />';

// java.util.Date example
$formatter = new Java('java.text.SimpleDateFormat',

This crash happens when you add the following to your php.ini

extension=php_java.dll

The php_java.dll from http://pecl4win.php.net/ext.php/php_java.dll and the php_java.dll which is part of the official pecl for windows download crash the php executable.

Either remove the php_java.dll from the official pecl4win download or or fix this bug.

Edin, I'd prefer the former.

Short of deleting it from the CVS it is not possible atm.

Java extension is not maintained and probably does not work on any platform.

I read in some discussions that PHP-Java Bridge is a replacement to PHP Java integration method. However, PHP-Java Bridge documentation shows only methods of calling from PHP to Java application server but not calling Java classes in-process. I would like to be able to call Java libraries from PHP.

If PHP Java integration were to be discontinued, manual page should be updated. I spent quite a bit of time trying to figure out why the integration did not work because there is no indication that it may not.

Hi,

the documentation which comes with PHP clearly states that ext/java only works with some older versions of PHP4. I don't think ext/java is mentioned in the PHP manual page, at least not on debian.

Calling Java classes in-process is not possible unless you use a PHP implementation written in pure Java. For the Zend PHP engine you need an external Java process. I think this is what you mean with "Java application server".
