PHP com Tomcat

Pesquisei na internet e vi que o PHP pode ser conectado com o Tomcat (além do Apache Server HTTP). Como já tenho rodando o tomcat na minha máquina por conta de uma aplicação de ScadaBR, queria fazer o uso dele mesmo.
Segui o tutorial desse link:
http://php-java-bridge.sourceforge.net/pjb/tomcat6.php
Mas quando coloco para acessar o localhost com /JavaBridge fica dando erro, alguém sabe o que poderia ser?
