Quercus: Java and PHP integration

I was try Quercus these days, I want to create a java PHP integration module, after looking at the tutorials, I was stack at the part below:

Step 3: Create com.caucho.quercus.QuercusModule and place it in $webApp/WEB-INF/classes/META-INF/services example.HelloModule

BTW, the demo http://www.caucho.com/resin-3.0/quercus/tutorial/module/hello.php or http://quercus.caucho.com/quercus-3.1/examples/quercus-module/hello.php is not working as well.

Can somebody help me with this probl开发者_StackOverflow中文版em? Thank you.

Reference:

http://www.caucho.com/resin-3.0/quercus/tutorial/module/index.xtp

http://quercus.caucho.com/quercus-3.1/doc/quercus.xtp#module

Step 3: Create com.caucho.quercus.QuercusModule and place it in $webApp/WEB-INF/classes/META-INF/services example.HelloModule

Means you need to create a file named com.caucho.quercus.QuercusModule and put it into $webApp/WEB-INF/classes/META-INF/services folder, the content should be example.HelloModule. The documentation is really not clear :(
