Using SOAP-encoded arrays
Passing SOAP-encoded arrays can cause problems if not understood.
Though commonly used in web services, SOAP-encoded arrays can cause problems when used with Web Service Description Language (WSDL) based applications. SOAP-encoded arrays are often created when you work with tools from Microsoft. SOAP-encoded arrays are not Web Services Interoperability (WS-I) compliant, which is the standard for IBM® Integration Designer.
Since these arrays are sometimes used with a web services binding based on Java API for XML-based RPC (JAX-RPC), IBM Integration Designer provides a quick fix that you can use should errors appear in the problems view. The quick fix changes the XML Schema Definition (XSD) using these arrays to have an unbounded attribute assigned to the field using the array type. In most cases, this quick fix will resolve problems with this kind of array.
You should only use SOAP-encoded arrays with the JAX-RPC transport protocol.
