I wanted to use Java_Bridge to use my java class in php file. But, for installing javabridge in my windows system i need java-x86-windows.dll which am unable to find. Where can i get this java-x86-windows.dll and is there any other method to call java functions form a php file?
You can download it from this site or you may try on sourceforge
The PHP/Java Bridge is an implementation of a streaming, XML-based network protocol, which can be used to connect a native script engine, for example PHP, Scheme or Python, with a Java virtual machine.
Another option is to use the Zend Server implementation of the Java/PHP bridge, I have used this in a production environment and its is very good. It doesn't require a Java server such as tomcat and provides a full PHP stack (apache, PHP and MySQL) reducing complexity (less moving parts). You can get here:
http://www.zend.com/en/products/server/free-edition
Remember that you will have to add your jars to the Zend classpath in the watchdog-jb.ini file using the appropriate path delimiter for your OS (; for windows, and : for linux) and restart the server. You can then call your classes by:
$myClass = new Java("com.someclass", $data); //Your constructor
It is very similar to the sourceforge version from then onwards. Hope that helps.
