SAP Netweaver Gateway JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with SAP Netweaver Gateway.



Use the Tableau Desktop business intelligence tool to connect to SAP Netweaver Gateway data.

With CData Drivers for SAP Netweaver Gateway, you can use data access standards to unlock connectivity to business intelligence tools like Tableau. The CData JDBC Driver for SAP Netweaver Gateway allows you to connect from Tableau on Windows and macOS. This article covers how to discover schemas and query SAP Netweaver Gateway data data in real-time.

NOTE: If you are using Tableau 2020.3 or higher, you can use the CData Tableau Connector for SAP Netweaver Gateway. If you wish to connect to SAP Netweaver Gateway data in Tableau Online, you will need to use CData Connect Cloud.

Connect to SAP Netweaver Gateway in Tableau

Before starting Tableau, make sure you've placed the .jar file in the correct folder:

  • Windows: C:\Program Files\Tableau\Drivers
  • MacOS: ~/Library/Tableau/Drivers

Once your .jar file is in place, establishing a connection is straightforward.

  1. Start Tableau.
  2. Under To a Server, select More.
  3. Select Other Databases (JDBC)
  4. Enter the JDBC connection string in the URL field.
  5. SAP Gateway allows both basic and OAuth 2.0 authentication. You can use basic authentication to connect to your own account, or you can use OAuth to enable other users to retrieve data from your service with their accounts. In addition to authenticating, set the following connection properties to access SAP Gateway tables.

    • Url: Set this to the URL of your environment, or to the full URL of the service. For example, the full URL might appear as: https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/. In this example, the environment URL would just be: https://sapes5.sapdevcenter.com.
    • Namespace: Set the appropriate Service Namespace. In the example above, IWBEP is the namespace. It is optional if the full URL to the service is specified.
    • Service: Set this to the service you want to retrieve data from. In the example above, the service is GWSAMPLE_BASIC. It is not required if the full URL is specified.

    Authenticate via Basic Authentication

    In basic authentication, you use your login credentials to connect. Set the following properties:

    • User: This is the username you use to log in to SAP Gateway.
    • Password: This is the password you use to log in to SAP Gateway.

    Authenticate via OAuth Authentication

    You can connect to SAP Gateway using the embedded OAuth connectivity (without setting any additional authentication connection properties). When you connect, the OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the SAP Netweaver Gateway JDBC Driver. Either double-click the .jar file or execute the .jar file from the command-line.

    From Windows:

    java -jar 'C:\Program Files\CData\CData JDBC Driver for SAP Netweaver Gateway\lib\cdata.jdbc.sapgateway.jar'

    From MacOS:

    java -jar cdata.jdbc.sapgateway.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

    The following is a sample URL created in the designer:

    jdbc:sapgateway:User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/;InitiateOAuth=GETANDREFRESH;
  6. Select Sign in.

Discover Schemas and Query Data

  1. Select CData from the Database pull-down menu.
  2. Select CData from the Schema pull-down menu.
  3. Drag the table onto the join area. You can include multiple tables.
  4. Select Update Now or Automatically Update. Update Now lets you preview the first 10,000 rows of the data source (or enter the number of rows you want to see in the Rows text box). Automatically Update automatically reflects the changes in the preview area.
  5. In the Connection menu, select the Live option, so that you skip loading a copy of the data into Tableau and instead work on real-time data.
  6. Click the tab for your worksheet. Columns are listed as Dimensions and Measures, depending on the data type. The CData Driver discovers data types automatically, allowing you to leverage the powerful data processing and visualization features of Tableau.
  7. Click and drag a field from the Dimensions or Measures area to Rows or Columns. Tableau creates column or row headers.
  8. Select one of the chart types from the Show Me tab. Tableau displays the chart type that you selected.
