Creating an SQL ServiceRequest

Creating an SQL ServiceRequest - Overview

A serviceRequest uses information specified on the server-side in the nexaweb-data.xml file to access external data. You specify information for a serverRequest to use on the server side in a dataRequestDefinition. The dataRequestDefinition either includes an SQL statement to access the external data or references an SQL statement specified in the nexaweb-sql.xml file.

Therefore, creating a serviceRequest on the server requires the following major steps:

Specifying the information to process the request on the server
