  <!-- note that either style="message" OR provider="java:MSG" both work
-->
  <service name="service" provider="java:MSG">   
    <parameter name="className"

    <parameter name="allowedMethods" value="executeDataservice" />
  </service>
</deployment>  
 
Thanks for your help...

Please post the WSDL and the WSDD for the service.

	I am executing a web service with no input parameters so the
SOAP body is empty like so:
	 
	<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
	   <soapenv:Body/>
	</soapenv:Envelope>
	 
	I am getting an NPE returned before I even hit my Web Service,
so I am assuming the exception is happening in Axis somewhere (I'm not
seeing a stack trace). Here is the response:
	 
	<?xml version="1.0" encoding="UTF-8"?>
	<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<soapenv:Body>
	  <soapenv:Fault>
	   <faultcode>soapenv:Server.userException</faultcode>
	   <faultstring>java.lang.NullPointerException</faultstring>
	   <detail/>
	  </soapenv:Fault>
	</soapenv:Body>
	</soapenv:Envelope>
	 
	I get this using Coral and Systinet as my clients. When I
generate an Axis client, I do not get an NPE but I get a node added to
my body with the operation name in it (which I don't want to see as my
logic depends on the body to be empty when no inputs are provided).
	 
	Any help would be greatly appreciated!
	 
	Thanks,
