RE: custom serializer problems

Wed, 29 Sep 2004 07:50:00 -0700 

Apparently I don't have the serializer configured and/or implemented properly.  I get 
the following "No serializer found" error when I try to call the method that returns a 
jdom.  Does anyone know where I can get more information about writing custom 
serializers for axis?

Subject: custom serializer problems


I'm trying to write a custom serializer for the jdom Element (org.jdom.Element).  I've 
written the serializer,deserializer,factories and added the type mapping to the wsdd 
file.  The service deploys and updates the server-config with the typeMapping Element 
but when javaToWsdl tries to generate the wsdl I having some problems.  Specifically 
I'm getting the following message;
        - The class org.jdom.Element does not contain a default constructor, which is 
a requirement for a bean class.  The class cannot be converted into an xml schema 
type.  An xml schema anyType will be used to define this class in the wsdl file.

The typeMapping node in the wsdd file is 
<typeMapping qname="myjdomNS:LeinResponse" 
xmlns:myjdomNS="http://jdom.soapenabled.armada.com";
        languageSpecificType="java:org.jdom.Element"
        serializer="com.armada.soapenabled.JdomElementSerializerFactory"
        deserializer="com.armada.soapenabled.JdomElementDeserializerFactory"
        encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>

And once this is deployed the typeMapping node in the server-config.wsdd file is
<typeMapping deserializer="com.armada.soapenabled.JdomElementDeserializerFactory"      
 encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; qname="ns1:LeinResponse"    
  serializer="com.armada.soapenabled.JdomElementSerializerFactory" 
type="java:org.jdom.Element" 
        xmlns:ns1="http://soapenabled.armada.com"/>

The is not much documentation on creating a custom serializer but I think I've got it. 
 I believe the problem may lie in the javaToWSDL code but I'm not sure.  My plan was 
to let the WSDL get generated and then tweak as needed but that may not be possible.  
Anyone have any thoughts?
