Title: .NET multi dimensional array

What you can do is modify the wsdl as follows:

Replace the following:

with this:

This will tell .NET to use an array of arrays (a jagged array) instead of a 2 dimensional array.

If you place the 2-D array in a class (bean), axis will generate the latter code for it, so .NET will be able to understand it without manual modification of the wsdl. Unfortunately, there is a bug in axis which prevents it from deserializing 2D arrays properly if they are class properties (http://nagoya.apache.org/bugzilla/show_bug.cgi?id=14033). If your axis web service is only sending them back to a .NET client, this shouldn't cause you any problems, but you won't be able to send one from the client to the server.

I find it strange that axis generates the type information inconsistently, depending on whether it is a bean property or not. Is there any reason for this, axis developers?

One other thing, I am having trouble getting .NET to read in even single dimensional arrays when they are class properties, so the solution of putting it into a class might be a dead end too. I'm still investigating this.

Let me know how you get on.

Subject: .NET multi dimensional array

I have a Java web service published to Axis that returns a 2 dimensional String array. It take no parameters:
public String[][] getTwo()
{
        String[][] multiArray = new String[2][3];
        multiArray[0][0] = "One1";
        multiArray[0][1] = "One2";
        multiArray[0][2] = "One3";

        multiArray[1][0] = "Two1";
        multiArray[1][1] = "Two2";
        multiArray[1][2] = "Two3";

        return multiArray;

}

I generate the WSDL and it looks great.
I generate Java clients with WSDL2Java.
Execute this code and it works great.

I then go into .NET
If I call a method that returns a one dimensional String array, then .NET works good.

But, the return method in .NET of getTwo() only returns a 'single' dimension array. I cannot cast it to anything else.

If I leave it at a single dimension, and run it, .NET give a message saying it does not suppor it.
Is this true?
It is saying I should use an array of arrays instead.
