Axis clients donít set xsi:type attribute when marshalling arrays of java.lang.Objects.

           Summary: Axis clients donít set xsi:type attribute when
                    marshalling arrays of java.lang.Objects.
           Product: Axis
           Version: current (nightly)
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Serialization/Deserialization
        AssignedTo: axis-dev@xml.apache.org
        ReportedBy: ckowal@actional.com


When an Axis client sends an array of object, the xsi:type attribute should be 
set on each element, so that the server knows what type it is.  The Axis client 
should also look at this attribute when receiving a reply to know what type 
itís dealing with.

The problem can be reproduced with .NET using the following client and server:
(The server will get a cast failure because it doesn't know the arguments real 
type).


Axis Client:

	public void doIt() throws Exception
	{
		ArrayOfAnyType arg = new ArrayOfAnyType();
		ArrayOfAnyType rtrn;

		Object[] obj = new Object[10];

		for (int i = 0; i < 10; i++)
		{
			obj[i] = new MyType();
			((MyType)obj[i]).setI(i);
			((MyType)obj[i]).setS("string " + i);
		}

		arg.setAnyType(obj);

		rtrn = fport.test(arg);

		for (int i = 0; i < 10; i++)
			System.out.println((MyType)rtrn.getAnyType(i));
	}


ASP.NET C# Server:

	public struct myType
	{
		public int i;
		public string s; 
	}
			
	[WebMethod]
	public object[] Test(object[] arg)
	{
		object[] rtrn = new object[arg.Length];

		for (int i = 0; i < arg.Length; i++)
		{
			myType str = new myType();

                        // This will cause a cast failure because .NET
                        // doesn't know arg[i] is really of type myType

			str = (myType)arg[i];
			rtrn[i] = str;
		}

		return rtrn;
	}
