In my application i have converted a session ejb to a webservice. service works ok. i have generated the web service.xml using following xdoclet commands.

jboss-net.web-service urn="testService"

follwoing is the web service method signature

/**
* write entry method which writes a log entry
*
* @ejb.interface-method view-type = "both"
* @throws EJBException Thrown if the instance could not perform
* @jboss-net.web-method returnQName="ErrorStatus"
* the function requested by the container because of an system-level error.
*/
public String addOrder(Order orderobj) throws EJBException {

Order is a user define class which has order name, date generated and package vector which describes the packeges for a order.

follwoing is the web service xml file generated.

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

name="testService"
xmlns="http://xml.apache.org/axis/wsdd/"
targetNamespace="http://localhost:8080/testService"

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

<!-- The following are declarations of service endpoints targetted to
session beans -->











<!-- Operation mapping results -->







<!-- The following are typemappings for entity beans for implementing
the implicit web-service value-object pattern -->

<!-- The following are typemappings for bean-type value-objects -->

<!-- There follow merged custom web service descriptions -->





then i create a wsdl file and deploy the web service in jboss
when i call the webservice through web browser the wsdl file displays ok.
but when i call the webservice from a client program i got follwoing error
