ServiceConfigReader

public class ServiceConfigReader
extends DefaultHandler

Very basic config utility configures services based on a file having the following format:
<services>
<!-- you can add properties here -->
<property name="...." value="...."/>
...
<!-- you can add global handlers that will be put on all services -->
<globalHandler type="in|out" class="...."/>
...
<service name="..." wsrf="true|false" persistent="true|false" [wsdlLocation=" ... "]>
<interface class="" /> <!-- the interface defining your service -->
<implementation class=""/> <!-- the implementation of the service -->
<handler type="in|out" class="..."/> <!-- an in/out handler to add -->
<initTask class="..."/> <!-- a Java Runnable to run after deployment-->
<shutdownTask class="..."/> <!-- a Java Runnable to run before un-deployment -->
</service>
...
</services>
