Axis1 Serialization/Deserialization Issue

[Andrew Prinoli]

Hi,
I'm developing for my thesis a java project implemented ad the top of Axis1. I should implement an addition handler for Axis1 (and wss4j).
I've almost done all the work..but I have a big problem that I cannot solve..:
have to implement serialization/deserialization methods to a class (called SoapPair) using Axis serialization/deserialization.
The class SoapPair ,as the name indicates, contains a Soap message divided into header+body . At the constructor receives a MessageContext obect from Axis.

public class SoapPair{    
 
public SoapPair(MessageContext mc) {}
 
public Message getLeft(){
return leftmsg
}
 
public Message getRight(){
return rightmsg;
}
 

protected void _serialize(final OutputStream out) throws PostException {
}
 

public Message deSerialize(final InputStream in) throws PostException {
}
 

protected void _encodePayload(OutputStream out) throws PostException {
}
 

public Message decodePayload(InputStream in) throws PostException {
}

I have to implement those methods but I don't know how..
I have to call them from a test class that simulates Axis engine (passing to soappair a MessageContext obj).


Thanks in Advance

ok..I've googled around..
I've tried in the following way , but I still receive an exception (java.net.MalformedURLException) , while deserializing..

    
protected void _serialize(final OutputStream out) throws PostException {
System.out.println("SERIALIZING");
 
MessageContext msgContext = new MessageContext(newAxisServer());
msgContext.setEncodingStyle(null);
 
TypeMappingRegistry tmr = new TypeMappingRegistryImpl();
msgContext.setTypeMappingRegistry(tmr);
 
StringWriter writer = new StringWriter(); //temp
SerializationContext ser = new SerializationContext(writer,msgContext);
ser.setPretty(true);
ser.setSendDecl(false);
ser.setDoMultiRefs(false);
 
try {
QName qname = new QName("typeNS", "SoapPair");
 

ser.serialize(qname, new AttributesImpl(), this, null,Boolean.FALSE, Boolean.FALSE);
writer.flush();
XMLUtils.newDocument(new InputSource(new StringReader(writer.toString())));
}
catch(ParserConfigurationException e) {
e.printStackTrace();
return;
 
}
catch(SAXException e) {
e.printStackTrace();
return;
}
catch(IOException e) {
e.printStackTrace();
return;
}
 

}
 

 

 

 
public Message deSerialize(final InputStream in) throws PostException {
System.out.println("DESERIALIZING");
 
Reader reader = null;
MessageContext msgContext=new MessageContext(new AxisServer());
DeserializationContext dser = new DeserializationContext(new InputSource(reader), msgContext, null);
    
try {
dser.parse();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
 

If you have any idea please help me..
Thanks a lot..

Most likely unrelated to your problem but the first parameter to QName

QName qname = new QName("typeNS", "SoapPair");

is supposed to be a namespaceURI

"typeNS" isn't a URI - it is missing a URI scheme.

URI generic syntax

Aside:
I can only think of one reason why you have to deal with object (de)serialization in Axis 1.x - because the "RPC/encoded" messaging mode was Axis 1.x default mode of operation. Current generation web services do not support RPC/encoded at all because RPC/encoded caused more trouble then it was worth. So if that is in fact at the root of your problem then you may want to reconsider your approach in your current project.

Which style of WSDL should I use?

Hi..my aim is to serialize/deserialize my "SoapPair" class , that contains Axis MessageContext obj (SoapPair receives this from its constructor), not serializable object(when trying to normally serialize , it returns "axis MessageContext not serializable")..
How do I serialize/deser the SoapPair class?
Do I have to use SerializationContext/Deser context? How?
Thanks in Advance.
