RE: Web service receiving and returning org.w3c.dom.Element

Yes, I’ve also noticed a few quirks when using Axis with DII and it’s JAX-RPC implementation.

 

Try altering your client as follows:

 

SOAPMessage message = MessageFactory.newInstance().createMessage();

message.getSOAPBody().addDocument(documentXML);

Object[] params =  new Object[] { message.getSOAPBody().getFirstChild() };

Chris,

 

I did what you said, but now it’s happening a strage think.

 

My web service is:

 

import org.w3c.dom.Document;

 

public class ElementWS {

 

      public Document method(Document body){

            return body;

      }

}

 

And my WSDD is:

 

<deployment xmlns="http://xml.apache.org/axis/wsdd/"

            xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"

            xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance">

 

 <service name="ElementWS" provider="java:MSG">

  <parameter name="className" value="ElementWS"/>

  <parameter name="allowedMethods" value="method"/>

 </service>

 

</deployment>

 

My client is:

 

String urlWS = "http://localhost:8081/axis/services/ElementWS";

              

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

DocumentBuilder builder = factory.newDocumentBuilder();

Document documentXML = builder.parse("Test.xml");

 

Object[] params = {documentXML};

Service service = new Service();

Call call = (Call) service.createCall();

call.setTargetEndpointAddress( new java.net.URL(urlWS) );

call.setOperationName( "method" );

Document ele = (Document) call.invoke(params);

 

I converted the web service return to give a println and see the content and all I got was this:

 

<?xml version="1.0" encoding="UTF-8"?>

 

What happened with the content of my input XML document? Where are all nodes?

 

Thanks a lot,

 

 

Fabrício.

Fabrício, sounds like you trying to use Axis in message mode – sending and receiving raw XML documents? You need to change from RPC/encoded to document/literal, plus change your wsdd as follows:

 

-          service provider should be “java:MSG”

-         remove all the type mappings

Hello all,

 

Does anyone have a real example of a web service that receives and returns an org.w3c.dom.Element? I created one, but doesn’t work! :’-((((((((((((

 

Always I get this error:

 

org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.

 

My web service is just this:

 

import org.w3c.dom.Element;

 

public class ElementWS {

 

     

      public Element method(Element e){

            return e;

      }

}

 

And my wsdd is:

 

<deployment xmlns="http://xml.apache.org/axis/wsdd/"

            xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

 

 <service name="ElementWS" provider="java:RPC">

  <parameter name="className" value="ElementWS"/>

  <parameter name="allowedMethods" value="*"/>

 

  <typeMapping

      qname="myNS:Element"

      xmlns:myNS="urn:ElementWS"

      languageSpecificType="java:org.w3c.dom.Element"

      deserializer="org.apache.axis.encoding.ser.ElementDeserializerFactory"

      serializer="org.apache.axis.encoding.ser.ElementSerializerFactory"/>

 

 </service>

 

</deployment>

 

In my client I used registerTypeMapping too. This is a piece of my client:

 

…

               DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

               DocumentBuilder builder = factory.newDocumentBuilder();

               Document documentXML = builder.parse("People.xml");

               Element e = documentXML.getDocumentElement();

                       

               Object[] params = {e};

              

               Service service = new Service();

              

               QName qnElement = new QName("urn:ElementWS", "Element");

              

               Call call = (Call) service.createCall();

             

               call.registerTypeMapping(Element.class, qnElement ,

                         new org.apache.axis.encoding.ser.ElementSerializerFactory(),

                         new org.apache.axis.encoding.ser.ElementDeserializerFactory());

 

               call.setTargetEndpointAddress( new java.net.URL(urlWS) );

              

               call.setOperationName( new QName(urlWS, "method") );

              

               Element ele = (Element) call.invoke(params);

              

               System.out.println(ele);

 

Does anyone can see why I’m getting this error?

 

Thanks very, very, very, very much!!

 

Fabrício.
