<br><b>Code</b>: rsb:print<br><b>Error</b>: Formatter [ extable ] failed in the evaluation of ???????????????????Mule ?????????[datasource] ?????????????????????????????? </p> <p> This article demonstrates how to use the [company_name] Mule Connector for [service] inside of a Mule project to create a Web interface for [datasource]. The application created allows you to request [datasource] using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any [company_name] Mule Connector to create a Web interface for the [x|db('v_drivers_count.total.count')]+ available data sources. </p> <ol> <li>Create a new Mule Project in Anypoint Studio.</li> <li>Add an HTTP Connector to the Message Flow.</li> <li>Configure the address for the HTTP Connector. <img src='[x|UrlRootAbs]\kb\articles\mule-anypoint-studio-1.png' title='Add and Configure the HTTP Connector'/></li> <li>Add a [company_name] [service] Connector to the same flow, after the HTTP Connector.</li> <li>Create a new Connection (or edit an existing one) and configure the properties to connect to [service] (see below). Once the connection is configured, click Test Connection to ensure the connectivity to [service].
