Returning map / list with axis ws

[jaki jane]

Hi all,

I have an axis WS client calling a remote ejb3 web service as below:

 Call call    = (Call) service.createCall();
                   call.setTargetEndpointAddress( new java.net.URL(endpoint) );
                   call.setOperationName(new QName("http://session.um.com/", "getAuc") );
 
                 
                   call.addParameter("arg0",
                                     org.apache.axis.Constants.XSD_INT,
                                     javax.xml.rpc.ParameterMode.IN);
                 
         
                   call.setReturnClass(HashMap.class);
                   HashMap ret =  (HashMap) call.invoke( new Object[] {"1"}

Thought it throws no error, the returned Map / List never has any contents in them. Also, if instead of setReturnClass I try to use setReturnType(org.apache.axis.Constants.XSD_ANY) it gives me the below error:

could not find deserializer for type {http://www.w3.org/2001/XMLSchema}any

Have you looked at the SOAP that gets transmitted? You can use a tool like SOAPUI. In general, I would avoid using Java classes as return types that have no type mapping using XML Schema (like any kind of Map). You may have to write a custom serializer/deserializer for that.
