axi2(1.5) is not defining the elements in wsdl types

Question

Hi I am trying to create a web service as an "aar" file. But when i deploy it... i can not see the wsdl:types or xsd ... here is the wsdl

<wsdl:definitions targetNamespace="http://ws.apache.org/axis2"&gt;
<wsdl:documentation>Inverse</wsdl:documentation>
<wsdl:types/>
<wsdl:message name="getInverseRequest"/>
<wsdl:message name="getInverseResponse"/>

<wsdl:portType name="InversePortType">
  <wsdl:operation name="getInverse">
    <wsdl:input message="axis2:getInverseRequest" wsaw:Action="urn:getInverse"/>
    <wsdl:output message="axis2:getInverseResponse" wsaw:Action="urn:getInverseResponse"/>
  </wsdl:operation>
</wsdl:portType>

any idea??
