Shameera Rathnayaka updated AXIS2-4918:
---------------------------------------

    Attachment: AXIS2-4918.patch

Hi Shao, 

In your wsdl you have an element call 'query' in both  http://comscore.com/PlanTargetQuery
and http://comscore.com/ReportQuery targetnamespaces. But isComponetExists(XmlSchema schema,QName
componentQName,int componetType) {....} method in SchemaCompiler class doesn't check schema
targetnamespace with component namespaceURI. Therefore even component element(query) from
the http://comscore.com/ReportQuery schema it return true for http://comscore.com/PlanTargetQuery
schema as it only checks localpart of component element. i have attached a patch for this.


After adding this patch you will encounter same problem again.But due to another reason.Therefore
successfully generate all classes you have to change your wsdl to some extend i have show
it 
below 

in ReportQuery schema

<s:element name="query">
  <s:complexType>
    ......
  </s:complexType>
</s:element>

***************change abve segment to 

<s:element name="query" type="s2:testQuery" />
<s:complexType name="testQuery">
  ......
</s:complexType>

This is because axis2 doesn't support when ref element has an anonymous ComplexType. I have
created improvement issue[1] for that.

Thanks 
Shameera
