WSAViewer is a basic tool for viewing the SOAP messages between a given source and destination, which you determine at startup. As such, it functions as a "man in the middle" between the client and the Web service. It is useful if you are only interested in viewing the content of the SOAP request and response. The simplicity of this tool makes it handy to use when debugging OpenEdge Web services for which viewing the well-defined SOAP formats is the primary focus. For more information on this tool, see Test and debug OpenEdge SOAP Web Services.
