New to Java

Hi I am new to Java and Netbeans.

I am writing an java application which need to provide some services to PHP application. So I need webservices. In java application i do not provide any user-interface, all user interaction handled by PHP application.

I have developed my required classes now it is time to expose this classes to PHP application. I wrote this classes in NetBeans 6.9 by creating Java-->Java Application not a web application. May i create webservices inside java application instead of web application ? How can i create SOAP webservices? Is there a good tutorial for netbeans 6.9 for webservices ?

thanks for your help
