Problem with Apache Axis sever and .NET Framework client

[Marco]

Hello,
I am realizing an application client in VisualStudio .NET 2002 with
Framework 1.1 in VisualBasic, and must communicate with a server
realized in java with Apache Axis version 1.2RC2.
I have used a console application and then I have added a webreference
and in the URL I have inserted the wsdl.
The code is simple:

Dim myStringa() As String
Dim i As Integer
Dim prova As New WebReference1.MySoapService
myStringa = prova.getStringArray("ok")
For i = 0 To myStringa.Length - 1
Console.WriteLine(myStringa(i))
Next
Console.In.Read()

When I execute the getStringaArray, It comes back the error "An
unhandled exception of type ' System.InvalidOperationException'
occurred in system.xml.dll".
Instead if I execute a getString it works correctly.
I have read of problems about deserialization of empty array but it is
not my case because the Array that would return is composed of 3
strings.
Which it could be the problem?
There are other parameters that I am ignoring?
From the server side, the user that has realized it says that it is a
my problem because the method getStringArray if called by a java
client works ccorrectly.

Thank you
Marco

Hi Marco

This can be an encoding style problem. Ask the serverside developer, which
encoding style is used.

Possible encodings can be: doc-literal, wrapped-literal, rpc.

If I remember correctly .NET uses wrapped-literal as default, but you can
change it.
In the Java world (been there, too), it can be both...but is most likely
"rpc", because support for the wrapped style was very poor in earlier
versions of Axis.

The encoding style tells the SOAP engine (Axis og .NET) something about the
structure of input, output messages and their parameters when they are
serialized and deserialized to/from XML.

Hope this helps...Should give you some clue, where to look for this
(interop) problem.
