Get the Report →Access SAP Data in Mule Applications Using the CData JDBC Driver
Create a simple Mule Application that uses HTTP and SQL with CData JDBC drivers to create a JSON endpoint for SAP data.
The CData JDBC Driver for SAP ERP connects SAP data to Mule applications enabling read functionality with familiar SQL queries. The JDBC Driver allows users to easily create Mule applications to backup, transform, report, and analyze SAP data.
This article demonstrates how to use the CData JDBC Driver for SAP ERP inside of a Mule project to create a Web interface for SAP data. The application created allows you to request SAP data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData JDBC Driver to create a Web interface for the 200+ available data sources.
- Create a new Mule Project in Anypoint Studio.
- Add an HTTP Connector to the Message Flow.
- Configure the address for the HTTP Connector.
- Add a Database Select Connector to the same flow, after the HTTP Connector.
- Create a new Connection (or edit an existing one) and configure the properties.
- Set Connection to "Generic Connection"
- Select the CData JDBC Driver JAR file in the Required Libraries section (e.g. cdata.jdbc.saperp.jar).
- Set the URL to the connection string for SAP
The driver supports connecting to an SAP system using the SAP Java Connector (SAP JCo). Install the files (sapjco3.jar and sapjco3.dll) to the appropriate directory for the hosting application or platform. See the "Getting Started" chapter in the help documentation for information on using the SAP JCo files.
In addition, you can connect to an SAP system using Web services (SOAP). To use Web services, you must enable SOAP access to your SAP system and set the Client, RFCUrl, User, and Password properties, under the Authentication section.
For more information, see this guide on obtaining the connection properties needed to connect to any SAP system.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the SAP JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.saperp.jar
Fill in the connection properties and copy the connection string to the clipboard.
- Set the Driver class name to cdata.jdbc.saperp.SAPERPDriver.
- Click Test Connection.
- Set the SQL Query Text to a SQL query to request SAP data. For example:
SELECT MANDT, MBRSH FROM MARA
- Add a Transform Message Component to the flow.
- Set the Output script to the following to convert the payload to JSON:
%dw 2.0 output application/json --- payload
- To view your SAP data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The SAP data is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.
At this point, you have a simple Web interface for working with SAP data (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools. Download a free, 30 day trial of the JDBC Driver for SAP and see the CData difference in your Mule Applications today.
