Map Serializer error during interop between .NET and AXIS

[Sateesh Ayyagari]

Hi,

  I am trying to interop between a .NET client and a AXIS web service.  AXIS supports Map types to be serializable.  When I serialize a Hashtable in a Java Web Service, AXIS generates the following schema in the types element of the WSDL.

- <wsdl:types>

- <schema targetNamespace="http://xml.apache.org/xml-soap" xmlns="http://www.w3.org/2001/XMLSchema">

  <import namespace="http://schemas.xmlsoap.org/soap/encoding/" />

- <complexType name="Map">

- <sequence>

- <element maxOccurs="unbounded" minOccurs="0" name="item">

- <complexType>

- <all>

  <element name="key" type="xsd:anyType" />

  <element name="value" type="xsd:anyType" />

  </all>

  </complexType>

  </element>

  </sequence>

  </complexType>

  </schema>

  </wsdl:types>

 

  On the .NET client side, the wsdl.exe produces the following error.

 

Error: Unable to import binding 'HashServErrorSoapBinding' from namespace 'http:
//localhost/axis/services/HashServError'.
  - Unable to import operation 'getCollection'.
  - Object reference not set to an instance of an object.

If you would like more help, please type "wsdl /?".

 

    My guess is that the error is because of the unability of .NET to import the "targetNamespace" of Map schema.  Am I right?  Any comments would be appreciated. 

 

Thanks.

Sateesh.
