Sorry, But I still had a problem posting the WSDL. This time it should work: 1. This is the WSDL that is generated by the .Net client: <?xml version="1.0" encoding="utf-8"?> | <definitions xmlns:tns="http://org/jaws" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="TestFacadeService" targetNamespace="http://org/jaws" xmlns="http://schemas.xmlsoap.org/wsdl/"> | <types> | <xsd:schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap11-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="http://org/jaws"> | <xsd:complexType name="MyClass"> | <xsd:sequence> | <xsd:element name="a" nillable="true" type="xsd:string" /> | </xsd:sequence> | </xsd:complexType> | </xsd:schema> | </types> | <message name="TestFacade_Test1"> | <part name="String_1" type="xsd:string" /> | <part name="MyClass_1" type="tns:MyClass" /> | </message> | <message name="TestFacade_Test1Response"> | <part name="result" type="xsd:string" /> | </message> | <portType name="TestFacade"> | <operation name="Test1" parameterOrder="String_1 MyClass_1"> | <input message="tns:TestFacade_Test1" /> | <output message="tns:TestFacade_Test1Response" /> | </operation> | </portType> | <binding name="TestFacadeBinding" type="tns:TestFacade"> | <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc" /> | <operation name="Test1"> | <soap:operation soapAction="" /> | <input> | <soap:body use="literal" namespace="http://org/jaws" /> | </input> | <output> | <soap:body use="literal" namespace="http://org/jaws" /> | </output> | </operation> | </binding> | <service name="TestFacadeService"> | <port name="TestFacadePort" binding="tns:TestFacadeBinding"> | <soap:address location="http://TLVD60154031A:8080/TestFacade/TestFacade" /> | </port> | </service> | </definitions> 2. This is the WSDL that I get when I acces http://localhost:8080/TestFacade/TestFacade?wsdl: <definitions name='TestFacadeService' targetNamespace='http://org/jaws' xmlns='http://schemas.xmlsoap.org/wsdl/' xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/' xmlns:tns='http://org/jaws' xmlns:xsd='http://www.w3.org/2001/XMLSchema'> | <types> | <schema elementFormDefault='qualified' targetNamespace='http://org/jaws' xmlns='http://www.w3.org/2001/XMLSchema' xmlns:soap11-enc='http://schemas.xmlsoap.org/soap/encoding/' xmlns:tns='http://org/jaws' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'> | <complexType name='MyClass'> | <sequence> | <element name='a' nillable='true' type='string'/> | </sequence> | </complexType> | </schema> | </types> | <message name='TestFacade_Test1'> | <part name='String_1' type='xsd:string'/> | <part name='MyClass_1' type='tns:MyClass'/> | </message> | <message name='TestFacade_Test1Response'> | <part name='result' type='xsd:string'/> | </message> | <portType name='TestFacade'> | <operation name='Test1' parameterOrder='String_1 MyClass_1'> | <input message='tns:TestFacade_Test1'/> | <output message='tns:TestFacade_Test1Response'/> | </operation> | </portType> | <binding name='TestFacadeBinding' type='tns:TestFacade'> | <soap:binding style='rpc' transport='http://schemas.xmlsoap.org/soap/http'/> | <operation name='Test1'> | <soap:operation soapAction=''/> | <input> | <soap:body namespace='http://org/jaws' use='literal'/> | </input> | <output> | <soap:body namespace='http://org/jaws' use='literal'/> | </output> | </operation> | </binding> | <service name='TestFacadeService'> | <port binding='tns:TestFacadeBinding' name='TestFacadePort'> | <soap:address location='http://TLVD60154031A:8080/TestFacade/TestFacade'/> | </port> | </service> | </definitions> 3. I used a sniffer and this is what I got when I called test1() from my .Net client: POST /TestFacade/TestFacade HTTP/1.1 | | User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; MS Web Services Client Protocol 2.0.50727.42) | | Content-Type: text/xml; charset=utf-8 | | SOAPAction: "" | | Host: tlvd60154031a:8080 | | Content-Length: 316 | | Expect: 100-continue | | Connection: Keep-Alive | | HTTP/1.1 100 Continue | | <?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body&g... xmlns="http://org/jaws"><String_1 xmlns="">1</String_1></Test1></soap:Body></soap:Envelope> | HTTP/1.1 500 Internal Server Error | | Server: Apache-Coyote/1.1 | | X-Powered-By: Servlet 2.4; JBoss-4.0.4.GA (build: CVSTag=JBoss_4_0_4_GA date=200605151000)/Tomcat-5.5 | | Set-Cookie: JSESSIONID=00C7A2C43F19677B78910277825F9BDD; Path=/ | | Content-Type: text/xml;charset=UTF-8 | | Transfer-Encoding: chunked | | Date: Mon, 28 Aug 2006 12:27:41 GMT | | Connection: close | | 51 | | <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'><env:... | | 2a | | <env:Body><env:Fault>env:Client | | c | | | | 31 | | Cannot find child element: MyClass_1 | | e | | | | c | | </env:Fault> | | b | | </env:Body> | | f | | </env:Envelope> | | 0 | Regards, Zohar View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3967814#...
