Problem using Axis Web Services with .NET Client

           Summary: Problem using Axis Web Services with .NET Client
           Product: Axis
           Version: beta-3
          Platform: All
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Serialization/Deserialization
        AssignedTo: axis-dev@xml.apache.org
        ReportedBy: Saurabh.Mehta@sabre.com


I have developed a simple web service which echoes an array of strings. The web 
service works fine with a java client. But when I am using a .NET client 
application to generate the proxy class (using wsdl.exe tool in .NET), it 
generates the following warnings/errors:

Schema validation warning: Undefined 
complexType 'http://schemas.xmlsoap.org/soap/encoding/:Array' is used as a base 
for complex type restriction".
Schema validation warning: 
Type 'http://schemas.xmlsoap.org/soap/encoding/:Array' is not declared.

Warning: Schema could not be validated. Class generation may fail or may 
produce incorrect results.

Error: Unable to import binding 'DemoServiceSoapBinding' from 
namespace 'urn:SampleString'.
  - Unable to import operation 'getOperationDescs'.
  - The datatype 'Array' is missing.

I tried to change the SOAP specs to 1.1 and 1.2 but faced the same problem. I 
also changed the encoding of .NET to SOAP/RPC encoding. Is this a Bug or do I 
need to make any further changes to get this to work?

Another thing that I noticed is that if I copied the wsdl file (generated using 
the Java2WSDL command) from the server to the client, I could successfully 
create the proxy class in .NET. But if I used the WSDL file from the URL of the 
web service, I would get the errors mentioned above. Why are these two wsdl 
files different??

I have enclosed this wsdl file below. The interface used to generated the wsdl 
file is:

Interface
----------

public interface WebService extends java.rmi.Remote{
   public String[] echoStringArray(String[] strs);
}

The wsdl file generated by the Java2WSDL tool is:

I would appreciate any fixes to this bug or any changes that I need to make.
