Hello
below is my wsdl and binding.xjb that I am using. I want to rename the " <element name="getRelatedAssets">" name from 'getRelatedAssets' to 'getRelatedAssetsX'.
But when I run it i got the following error

[ERROR] compiler was unable to honor this property customization. It is attached to a wrong place, or its inconsistent with other bindings.


[ERROR] (the above customization is attached to the following location in the schema)
line 16 of file:/C:/Users/syedf/Documents/Checkers/4842/sample.wsdl

Here is my wsdl:
<wsdl:definitions targetNamespace="http://services.external.dmh.ibm.com"
xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:apachesoap="http://xml.apache.org/xml-soap"
xmlns:impl="http://services.external.dmh.ibm.com" xmlns:intf="http://services.external.dmh.ibm.com"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/"

<complexType name="WsaaAuthToken">

<element name="token" nillable="true" type="impl:WsaaAuthToken"/>

<element name="relationshipName" nillable="true" type="xsd:string"/>
</sequence>
</complexType>
</element>
......
</wsdl:definitions>

and here is my binding file:

<jaxws:bindings
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.1"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
wsdlLocation="C:\Users\syedf\Documents\Checkers\4842\sample.wsdl">
<jaxws:bindings node="wsdl:definitions/wsdl:types/xsd:schema">
<jaxb:bindings node="//xsd:element[@name='getRelatedAssets']">
<jaxb:property name="getRelatedAssetsX"/>
</jaxb:bindings>
</jaxws:bindings>
</jaxws:bindings>

Can anyone help me out in finding what wrong I am doing.
I appreciate.
