Creating and sending a SOAP message in java to a very simple web service
Question
I am currently trying to create and send a SOAP message to a very simple web service I've created myself.
Obviously the webservice have a wsdl file, which you can see here:
wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:ns="http://service.com" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:ns1="http://org.apache.axis2/xsd" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" targetNamespace="http://service.com">
<wsdl:documentation>Please Type your service description here</wsdl:documentation>
<wsdl:types>
<xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://service.com">
<xs:element name="echoTest">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" name="echoString" nillable="true" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="echoTestResponse">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" name="return" nillable="true" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
</wsdl:types>
<wsdl:message name="echoTestRequest">
<wsdl:part name="parameters" element="ns:echoTest"/>
</wsdl:message>
<wsdl:message name="echoTestResponse">
<wsdl:part name="parameters" element="ns:echoTestResponse"/>
</wsdl:message>
<wsdl:portType name="RequestHandlerPortType">
<wsdl:operation name="echoTest">
<wsdl:input message="ns:echoTestRequest" wsaw:Action="urn:echoTest"/>
<wsdl:output message="ns:echoTestResponse" wsaw:Action="urn:echoTestResponse"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="RequestHandlerSoap11Binding" type="ns:RequestHandlerPortType">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<wsdl:operation name="echoTest">
<soap:operation soapAction="urn:echoTest" style="document"/>
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:binding name="RequestHandlerSoap12Binding" type="ns:RequestHandlerPortType">
<soap12:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<wsdl:operation name="echoTest">
<soap12:operation soapAction="urn:echoTest" style="document"/>
<wsdl:input>
<soap12:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap12:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:binding name="RequestHandlerHttpBinding" type="ns:RequestHandlerPortType">
<http:binding verb="POST"/>
<wsdl:operation name="echoTest">
<http:operation location="echoTest"/>
<wsdl:input>
<mime:content type="application/xml" part="parameters"/>
</wsdl:input>
<wsdl:output>
<mime:content type="application/xml" part="parameters"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="RequestHandler">
<wsdl:port name="RequestHandlerHttpSoap11Endpoint" binding="ns:RequestHandlerSoap11Binding">
<soap:address location="http://localhost:8181/PayCheckHandlerMainWebService/services/RequestHandler.RequestHandlerHttpSoap11Endpoint/"/>
</wsdl:port>
<wsdl:port name="RequestHandlerHttpSoap12Endpoint" binding="ns:RequestHandlerSoap12Binding">
<soap12:address location="http://localhost:8181/PayCheckHandlerMainWebService/services/RequestHandler.RequestHandlerHttpSoap12Endpoint/"/>
</wsdl:port>
<wsdl:port name="RequestHandlerHttpEndpoint" binding="ns:RequestHandlerHttpBinding">
<http:address location="http://localhost:8181/PayCheckHandlerMainWebService/services/RequestHandler.RequestHandlerHttpEndpoint/"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
I've then used the google chrome plugin called Wizdler, to find out how the structure of soap messages should look like. THe Soap message for this example, should look like this.
<Envelope xmlns="http://www.w3.org/2003/05/soap-envelope">
<Body>
<echoTest xmlns="http://service.com">
<echoString>[string?]</echoString>
</echoTest>
</Body>
</Envelope>
So a pretty simple and straightforward SOAP message.. Nevertheless, Ican get it to work. I am trying to create the SOAP message with the following code:
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
String serverURI = "http://service.com";
// SOAP Envelope
SOAPEnvelope envelope = soapPart.getEnvelope();
// SOAP Body
SOAPBody soapBody = envelope.getBody();
soapBody.addNamespaceDeclaration("", serverURI);
SOAPElement soapBodyElem = soapBody.addChildElement("echoTest");
SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("echoString");
soapBodyElem1.addTextNode("HELLO?!?");
MimeHeaders headers = soapMessage.getMimeHeaders();
headers.addHeader("RequestHandler", serverURI);
soapMessage.saveChanges();
/* Print the request message */
System.out.print("Request SOAP Message:");
soapMessage.writeTo(System.out);
System.out.println();
The above code, produces the following SOAP message:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/>
<SOAP-ENV:Header/>
<SOAP-ENV:Body xmlns="http://service.com">
<echoTest xmlns="">
<echoString xmlns="http://service.com">HELLO?!?</echoString>
</echoTest>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I don't know why the echoString get the xmlns="http://service.com".. it should be in the echoTest tag instead.. and I guess this could be a part of the problem.
The response message looks like this:
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
<faultstring>namespace mismatch require http://service.com found none</faultstring>
<detail />
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
As can figure out, there is a problem with the namespace, but i seems like no matter what I do, the problem still occurs.
I hope someone can see the problem and maybe can provide a solution.
Any help will be greatly appreciated.

SOAPElement soapBodyElem = soapBody.addChildElement("echoTest","", serverURI);
SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("echoString","", serverURI);
But why are you constructing your SOAP explicitly?
If there is no particular reason, then use wsimport. Java classes + JAXB annotations will help you.

Anyways, after trying for a loooong time, I finally got it to work.. and of course just right after posting this question, I got it to work. So here is the complete java code for the problem described in the question:
public class PayCheckHandler {
public PayCheckHandler() throws Exception {
// TODO Auto-generated method stub
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection();
// Send SOAP Message to SOAP Server
String url = "http://localhost:8181/PayCheckHandlerMainWebService/services/RequestHandler?wsdl";
SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);
// print SOAP Response
System.out.println();
System.out.print("Response SOAP Message:");
soapResponse.writeTo(System.out);
soapConnection.close();
}
private static SOAPMessage createSOAPRequest() throws Exception {
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
String serverURI = "http://service.com";
// SOAP Envelope
SOAPEnvelope envelope = soapPart.getEnvelope();
SOAPHeader header = envelope.getHeader();
SOAPBody body = envelope.getBody();
// SOAP Body
SOAPBodyElement element = body.addBodyElement(envelope.createName("echoTest", "", serverURI));
element.addChildElement("echoString").addTextNode("Hello!!!");
return soapMessage;
}
public static void main(String[] args) throws Exception {
new PayCheckHandler();
}
}
Btw. if I absolutely didn't have to create my own SOAP messages manually, I would do as artem.ponchakov suggested.
