使用WSDL的SOAP客户端

Question

I am writing SOAP client using WSDL. I have similar code in PHP, which works fine. However, I have some problems in Java. Here is my code snippet:

Where should I define the path to my local WSDL file?

Any idea is welcome.

try 
{
 SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
 SOAPConnection soapConnection = soapConnectionFactory.createConnection();

 SOAPMessage soapResponse = soapConnection.call(mySampleQuery(), 
                     "https://www.webpagename.com");

 // Process the SOAP Response
 printSOAPResponse(soapResponse);

 soapConnection.close();
} 
catch (Exception e) 
{
 System.err.println("Error occurred while sending SOAP Request to Server");
 e.printStackTrace();
}

private static SOAPMessage queryFlightsByAerodrome() throws Exception
{     
 MessageFactory messageFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
 SOAPMessage soapMessage = messageFactory.createMessage();
 SOAPPart soapPart = soapMessage.getSOAPPart();

 String serverURI = "localfolder/wsdlfilename.wsdl";

 // SOAP Envelope
 SOAPEnvelope envelope = soapPart.getEnvelope();
 envelope.addNamespaceDeclaration("mydata", serverURI);

 // SOAP Body
 SOAPBody soapBody = envelope.getBody();
 SOAPElement soapBodyElem = soapBody.addChildElement("mySampleRequest", "mydata");

 SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("userId");
 soapBodyElem1.addTextNode("testuser");

 //...here I create soapBodyElem1 

 MimeHeaders headers = soapMessage.getMimeHeaders();

 headers.addHeader("SOAPAction", serverURI + "queryTestData");

 System.out.println("Content description: "+soapMessage.getContentDescription());
 soapMessage.saveChanges();

 /* Print the request message */
 System.out.print("Request SOAP Message:");
 soapMessage.writeTo(System.out);
 System.out.println();

 return soapMessage;
}

After running this code I get the following error at line SOAPMessage soapResponse = soapConnection.call(mySampleQuery(),"https://www.webpagename.com") :

Invalid Content-Type. Could be an error message instead of a SOAP message

That's your first clue right there.

Invalid Content-Type:text/html. Is this an error message instead of a SOAP response

That's another clue. Putting it all together:

1. Your client is connecting to the service
2. The service is returning a non-SOAP response payload (it's returning HTML instead), hence the reason why SAAJ is choking on it.

Typically, a webservice will return HTML when it's responding with a standard JavaEE container-generated error page, as against the expected SOAP response. The question now is: What is the error response that's being returned? Talk to your service provider for feedback on what you're doing wrong. Also, look into logging everything that hits your client somehow
