No serializer found!!!

Serializer Error:

I got this error when I call SOAP application:

HTTP ERROR: 500 ; nested exception is: java.io.IOException: No serializer found for class uk.example.dto.MessageRequest in registry

and I check the wsdl, another error occur:

AXIS error

Sorry, something seems to have gone wrong... here are the details:

Anyone, Please give me some Help or Hint

[crazypalm]

BTW, i did beanmapping already:

.......
<beanMapping qname="MessageRequest" xmlns:myNS="SoapDriver" languageSpecificType="java:uk.example.dto.MessageRequest"/>

[conormac]

Do you have a typeMapping definition in your web-service.xml? If not, that would be one problem.
To solve this issue, follow this excellent url on how to use jboss.net:

http://www.nsdev.org/jboss/stories/jboss-net.html

However, to auto-generate the typeMapping in your web-service.xml, don't forget to reference your value objects in the ejbdoclet ant task.

Hope this helps,
