[jboss-user] [JBoss jBPM] - 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:
anonymous wrote : 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!

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

Best regards,

Frank
