Calling WebService: "Incorrect request style parameter"


I have a web service deployed on WAS 6.40, which runs all right when I use the Web Services Navigator. However, when I try to use Axis to call it from a client, it just gives me an HTML page as return, where the error message says:

"Incorrect request style parameter value null."

The web service basically has a method "notify", which takes a String targetId and a Boolean available and returns a String.

The request that goes out with the test client in Web Service Navigator is:

POST /Notifier/Default?style=document HTTP/1.1

Host: drsd00146894a:50000

Content-Type: text/xml; charset="UTF-8"

Connection: close

Content-Length: 560

SOAPAction: ""

<?xml version="1.0" encoding="UTF-8" ?><SOAP-ENV:Envelope xmlns:SOAP-ENV="" xmlns:xsi="" xmlns:xs=""><SOAP-ENV:Header><sapsess:Session xmlns:sapsess=""><enableSession>true</enableSession></sapsess:Session></SOAP-ENV:Header><SOAP-ENV:Body><pns:notify xmlns:pns='urn:NotifierVi'><pns:targetId>test</pns:targetId><pns:available>false</pns:available></pns:notify></SOAP-ENV:Body></SOAP-ENV:Envelope>

With Axis, I do the following:

String endpoint =


Service service = new Service();

Call call = (Call) service.createCall();

call.setTargetEndpointAddress( new );

call.setOperationName(new QName("urn:NotifierVi", "notify"));

call.addParameter(new QName("urn:NotifierVi","targetId"), org.apache.axis.encoding.XMLType.XSD_STRING, ParameterMode.IN);

call.addParameter(new QName("urn:NotifierVi","available"), org.apache.axis.encoding.XMLType.XSD_BOOLEAN, ParameterMode.IN);

call.setReturnType( org.apache.axis.encoding.XMLType.XSD_STRING );

Object myParams[] = new Object[2];


myParams[1]=new Boolean(true);

call.invoke( myParams );

Now, I listened for the SOAP message that goes out on the wire, and there it says the following:

POST /Notifier/Default HTTP/1.0

Content-Type: text/xml; charset=utf-8

Accept: application/soap+xml, application/dime, multipart/related, text/*

User-Agent: Axis/1.3


Cache-Control: no-cache

Pragma: no-cache

SOAPAction: ""

Content-Length: 668

<?xml version="1.0" encoding="UTF-8"?>

<soapenv:Envelope xmlns:soapenv="" xmlns:xsd="" xmlns:xsi="">


<ns1:notify soapenv:encodingStyle="" xmlns:ns1="urn:NotifierVi">

<ns1:targetId xsi:type="xsd:string">uuid:CorePac</ns1:targetId>

<ns1:available href="#id0"/>


<multiRef id="id0" soapenc:root="0" soapenv:encodingStyle="" xsi:type="xsd:boolean" xmlns:soapenc="">true</multiRef>



Now, what is wrong with that one? I can't really see where there are request parameters are missing..

Any hint as to where I'm going wrong would be greatly appreciated..
