SUMMARY
This article discusses information about the data types that are supported by an XML Web service. The data types that are supported by an XML Web service are dependant on calling the Web service through the SOAP protocol or the HTTP protocol.



MORE INFORMATION
The following table lists the supported data types for the XML Web service methods when you use SOAP.

The previous data types are also supported for the return values of a Web service when an XML Web service is called through the SOAP protocol, the HTTP GET protocol, or the HTTP POST protocol.

The following limited data types are supported when an XML Web service is called through the HTTP GET protocol or the HTTP POST protocol.

The following supported types are limited:

Both the by-value parameter and the by-reference (in and out) parameter are supported when you use the SOAP protocol. The HTTP GET protocol and the HTTP POST protocol only support the by-value parameter. The by-reference parameter sends a value both ways by sending a value to the server and then sending the value back to the client.
