Dynamic client creation - web-services

Question

I have created a dynamic client for invoking a web service.This client invokes a web service called businessWorkItem.This service creates a workitem.I have given below the code:
package com.tcs.telecom.tib;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import org.apache.cxf.endpoint.Client;
import java.lang.reflect.Method;
public class WorkItem
{
public WorkItem()
{
}
public static void main(String str[]) throws Exception
{
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient(wsdlname);
Object createWorkItemRequest = Thread.currentThread().getContextClassLoader().loadClass(classname).newInstance();
Method m1 = createWorkItemRequest.getClass().getMethod("externalItemRefId", String.class);
m1.invoke(createWorkItemRequest,"9361117");
Object[] response = client.invoke("createWorkItem", createWorkItemRequest);
System.out.println("Response is " + response[0]);
}
}
When I run this code i am getting undeclared throwable exception.Error log:

Could anyone help me resolve this?

Answer 1

The stacktrace denotes duplicate property in wsdl. You have to modify the wsdl with jaxb binding. And provide the modified wsdl file to generate the client.

To customize wsdl with embedded bindings, you can do as below.
1. Add jaxb namespace to schema definition
2. Annotate the duplicate property with new name (In the example, I have annotated duplicate attribute with 'newname')
<s:schema elementFormDefault="qualified" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.0">
<xs:complexType>
<xs:sequence>
<xs:abc minOccurs="0" />
**<xs:abc minOccurs="1" >**
<xs:annotation>
<xs:appinfo>
<jaxb:property name="newname"/>
</xs:appinfo>
</xs:annotation>
**</xs:abc>**
</xs:sequence>
</xs:complexType>
