Subject Problem in custom axis (De)Serializers - Please help
Date Mon, 07 Feb 2005 12:54:38 GMT
Hi All,

I am using JiBX for implementing my own (De)Serializers replacing AXIS
default  (De)Serializers. However when I register my (De)Serializers
with AXIS's server-config.wsdd file and start my web service  deployed
on WebSphere 5.0, I am getting below detailed server stack trace :

Here is the code of my JiBX Deserializer java class :

--------------------------------------------------------
public class TriJibxDeser extends DeserializerImpl
{

  public TriJibxDeser(Class clas, QName qname, IUnmarshallingContext uctx)
  {
      m_javaType = clas;
      m_xmlType = qname;
      m_context = uctx;
  }

  public void onEndElement(String ns, String lname,
DeserializationContext dctx)
      throws SAXException
  {
      if(!m_xmlType.getNamespaceURI().equals(ns) ||
!m_xmlType.getLocalPart().equals(lname))
      {
          throw new SAXException("incompatable type passed to JiBX
deserializer");
      }
      MessageElement element = dctx.getCurElement();
      if(element != null)
      {
          String text = null;
          try
          {
              text = element.toString();
              value = m_context.unmarshalDocument(new StringReader(text));
          }
          catch(JiBXException e)
          {
              throw new SAXException("error in JiBX deserialization
: " + e.getMessage(), e);
          }
          catch(Exception e)
          {
              throw new SAXException("Error reading element text: "
+ e.getMessage(), e);
          }
      }
  }

  private static Log s_log;
  private QName m_xmlType;
  private Class m_javaType;
  private IUnmarshallingContext m_context;
}
--------------------------------------------------------

Can anyone tell how do I go ahead and debug this problem and find a
solution. Please suggest ?

Thanks & Regards,
Kumar.
