BPEL: invoke a oneway webservice

[zauberlehrling]

Hi,

I have a simple oneway webservice implemented by a stateless session bean:

package beispiel;

import javax.ejb.Stateless;
import javax.jws.Oneway;
import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
@Stateless
public class Asynchron {

 @WebMethod
 @Oneway
 public void createAccount( String name ) {
 System.out.println("Asynchron: "+name);
 }
}

After deployment I can find the following wsdl file:

<?xml version="1.0" encoding="UTF-8"?>
<definitions name="AsynchronService"
 targetNamespace="http://beispiel/"
 xmlns:tns="http://beispiel/"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema"
 xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
 xmlns="http://schemas.xmlsoap.org/wsdl/">
 <types>
 <xs:schema targetNamespace="http://beispiel/"
 version="1.0" xmlns:tns="http://beispiel/"
 xmlns:xs="http://www.w3.org/2001/XMLSchema">
 <xs:element name="createAccount" type="tns:createAccount" />
 <xs:complexType name="createAccount">
 <xs:sequence>
 <xs:element minOccurs="0" name="arg0"
 type="xs:string" />
 </xs:sequence>
 </xs:complexType>
 </xs:schema>
 </types>
 <message name="Asynchron_createAccount">
 <part name="createAccount" element="tns:createAccount" />
 </message>
 <portType name="Asynchron">
 <operation name="createAccount">
 <input message="tns:Asynchron_createAccount" />
 </operation>
 </portType>
 <binding name="AsynchronBinding" type="tns:Asynchron">
 <soap:binding style="document"
 transport="http://schemas.xmlsoap.org/soap/http" />
 <operation name="createAccount">
 <soap:operation soapAction="" />
 <input>
 <soap:body use="literal" />
 </input>
 </operation>
 </binding>
 <service name="AsynchronService">
 <port name="AsynchronPort" binding="tns:AsynchronBinding">
 <soap:address
 location="http://localhost:8080/Beispiel/Asynchron" />
 </port>
 </service>
</definitions>

And I want to call this webservice from my bpel process:

 <bpws:variables>
 <bpws:variable messageType="ns0:PojoService_sayHello"
 name="PartnerLinkRequest" />
 <bpws:variable messageType="ns0:PojoService_sayHelloResponse"
 name="PartnerLinkResponse" />
 <bpws:variable messageType="ns0:Asynchron_createAccount"
 name="Request" />
 </bpws:variables>
 ........
 <bpws:assign name="Asyn" validate="no">
 <bpws:copy>
 <bpws:from><![CDATA['Hallo Welt!']]></bpws:from>
 <bpws:to part="createAccount" variable="Request" />
 </bpws:copy>
 </bpws:assign>
 <bpws:invoke inputVariable="Request"
 name="Invoke"
 operation="createAccount"
 partnerLink="Asynchron"
 portType="ns0:Asynchron" />

with

<plnk:partnerLinkType name="ASYNCHRONPLT">
 <plnk:role name="role4" portType="wsdl:Asynchron" />
 </plnk:partnerLinkType>

If I start the bpel process, the oneway webservice Asynchron is contacted, but the webservices receives only null and JBoss reports an error:

22:26:41,893 INFO [STDOUT] Asynchron: null
22:26:41,903 ERROR [STDERR] [Fatal Error] :-1:-1: Premature end of file.

I recorded the bytes send to the application server with the TCP/IP-Monitor:

POST /Beispiel/Asynchron?datatype=SOAPMessage HTTP/1.1
SOAPAction: ""
Content-Type: text/xml; charset=UTF-8
User-Agent: Java/1.5.0_10
Host: localhost:8000
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
Content-Length: 239

<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
 <env:Header>
 </env:Header>
 <env:Body>
 <defaultNS:createAccount
 xmlns:defaultNS='http://beispiel/'>
 Hallo Welt!
 </defaultNS:createAccount>
 </env:Body>
</env:Envelope>

Is there an error in this?

Furthermore I recorded the text send to the application server, when I call the webservice with the webservice explorer:

POST /Beispiel/Asynchron HTTP/1.1
 Host: localhost:8000
 Content-Type: text/xml; charset=utf-8
 Content-Length: 325
 Accept: application/soap+xml, application/dime, multipart/related, text/*
 User-Agent: IBM Web Services Explorer
 Cache-Control: no-cache
 Pragma: no-cache
 SOAPAction: ""
 Connection: close
<soapenv:Envelope
 xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
 xmlns:q0="http://beispiel/"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 <soapenv:Body>
 <q0:createAccount>
 <arg0>Hallo Welt!</arg0>
 </q0:createAccount>
 </soapenv:Body>
</soapenv:Envelope>

I get the correct parameter in the jboss log: Hallo Welt!

22:34:55,136 INFO [STDOUT] Asynchron.: Hallo Welt!

My question: Is it not possible to transfer parameters to a oneway webservice?

Best regards,
