Help! VB to Apache Soap

[Kar YEOW]

I got a VB program using MSSOAP Tool kit 2.0 calling Apache SOAP 2.2 stateless session bean provider. The service is pretty basic.  Given a string it return another string.  But I got a runtime error 5053 from VB.     ------VB code---------- Private Sub Command1_Click()   Dim soapClient As MSSOAPLib.soapClient   Set soapClient = CreateObject("MSSOAP.SoapClient")   soapClient.mssoapinit ("http://localhost/RequirementServer.wsdl")   Debug.Print soapClient.getStatementText("10")   soapClient = Nothing End Sub   ----the WSDL-------- <?xml version='1.0' encoding='UTF-8' ?> <definitions  name='urn:RequirementServer'         targetNamespace= 'http://tempuri.org/wsdl/'         xmlns:wsdlns='http://tempuri.org/wsdl/'      xmlns:typens='http://tempuri.org/type'      xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/'      xmlns:xsd='http://www.w3.org/2001/XMLSchema'      xmlns='http://schemas.xmlsoap.org/wsdl/'>   <types>     <schema targetNamespace='http://tempuri.org/type'       xmlns='http://www.w3.org/2001/XMLSchema'       xmlns:SOAP-ENC='http://schemas.xmlsoap.org/soap/encoding/'       xmlns:wsdl='http://schemas.xmlsoap.org/wsdl/'       elementFormDefault='qualified'>     </schema>   </types>   <message name='getStatementTextRequest'>     <part name='statementNumber' type='xsd:string'/>   </message>   <message name='getStatementTextResponse'>     <part name='statementText' type='xsd:string'/>   </message>     <portType name='getStatementTextPortType'>     <operation name='getStatementText' parameterOrder='statementNumber'>       <input message='tns:getStatementTextRequest' />       <output message='tns:getStatementTextResponse' />     </operation>     </portType>     <binding name='getStatementTextBinding' type='tns:getStatementTextPortType' >     <soap:binding style='rpc' transport='http://schemas.xmlsoap.org/soap/http' />     <operation name='getStatementText' >         <soap:operation soapAction='' />         <input>             <soap:body use='encoded' namespace='http://tempuri.org/message/'           encodingStyle='http://schemas.xmlsoap.org/soap/encoding/' />         </input>         <output>             <soap:body use='encoded' namespace='http://tempuri.org/message/'           encodingStyle='http://schemas.xmlsoap.org/soap/encoding/' />         </output>     </operation>     </binding>     <service name='RequirementServer' >         <port name='getStatementTextPort' binding='tns:getStatementTextBinding' >             <soap:address location='http://localhost/soap/rpcrouter' />         </port>     </service> </definitions>
