Connect to SAP Netweaver Gateway Data in Aqua Data Studio

The CData JDBC Driver for SAP Netweaver Gateway integrates SAP Netweaver Gateway data with wizards and analytics in IDEs like Aqua Data Studio. This article shows how to connect to SAP Netweaver Gateway data through the connection manager and execute queries.

Create a JDBC Data Source

You can use the connection manager to define connection properties and save them in a new JDBC data source. The SAP Netweaver Gateway data source can then be accessed from Aqua Data Studio tools.

1. In Aqua Data Studio, select Register Server from the Servers menu.
2. In the Register Server form, select the 'Generic - JDBC' connection.
3. Enter the following JDBC connection properties:
   • Name: Enter a name for the data source; for example, SAP Netweaver Gateway.
   • Driver Location: Click the Browse button and select the cdata.jdbc.sapgateway.jar file, located in the lib subfolder of the installation directory.
   • Driver: Enter the Driver's class name, cdata.jdbc.sapgateway.SAPGatewayDriver.

   • URL: Enter the JDBC URL, which starts with jdbc:sapgateway: and is followed by a semicolon-separated list of connection properties.

     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.

     java -jar cdata.jdbc.sapgateway.jar

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

     A typical JDBC URL is below:
     jdbc:sapgateway:User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/;InitiateOAuth=GETANDREFRESH

Query SAP Netweaver Gateway Data

You can now query the tables exposed.
