INFO: Limitation of Array Bounds in Soap Toolkit 2.0 (306764)

MORE INFORMATION

For example, if a method of a SOAP server takes array of integers as a parameter, and a Visual Basic SOAP client application calls the method as follows:

    Dim i As Integer 
    Dim ArrayArg(5 To 10) As Integer
   
    For i = 5 To 10
        ArrayArg(i) = i * i * i
    Next
    
    soapclient.vbIntArray ArrayArg
				

the SOAP document that is sent to the server looks similar to the following:

...
<IntArrayArg xmlns:SOAPSDK2="http://www.w3.org/2001/XMLSchema" 
xmlns:SOAPSDK3="http://schemas.xmlsoap.org/soap/encoding/" SOAPSDK3:arrayType="SOAPSDK2:short[6]" 
xmlns:SOAPSDK4="http://www.w3.org/2001/XMLSchema-instance" SOAPSDK4:type="SOAPSDK3:Array">
  <SOAPSDK3:short>125</SOAPSDK3:short> 
  <SOAPSDK3:short>216</SOAPSDK3:short> 
  <SOAPSDK3:short>343</SOAPSDK3:short> 
  <SOAPSDK3:short>512</SOAPSDK3:short> 
  <SOAPSDK3:short>729</SOAPSDK3:short> 
  <SOAPSDK3:short>1000</SOAPSDK3:short> 
  </IntArrayArg><BR/>
...
				

The server method that is called cannot determine what array bounds the client are used for the array that is being passed.

A similar problem occurs when an array is returned to the client as a return value of the method call. In this case, the client program must use the normal array index (for example, in Visual Basic, indexes start at 0 or 1).
