Axis/.Net interop

[Brian Gladish]

In searching the archives I found the following e-mail, but there does not seem to be a resolution.   http://marc.theaimsgroup.com/?l=axis-user&m=106917131020548&w=2   I am running into exactly the same situation.  After deployment Axis presents a WSDL which has xsd:byte[][] for a Java byte[][].  I change the WSDL to use the type soapenc:base64Binary[], change the deployment descriptor to reference the custom WSDL file and redeploy.  At that point a .NET client is able to pass the data into the method, but is unable to get the return value, throwing an exception:   Top Exception:  System.InvalidOperationException Inner Exception: Cannot assign object of type System.SByte[][] to an object of type System.Byte[][]   The Java method is simply:               public byte[][] echoStreams( byte[][] data ) { return data; }   Any help would be greatly appreciated.   Brian J.
