Connect to SAP Netweaver Gateway Data in NetBeans

Connect to SAP Netweaver Gateway data in NetBeans with the data source configuration wizard.

The CData JDBC Driver for SAP Netweaver Gateway integrates connectivity to live SAP Netweaver Gateway data in IDEs that support JDBC. The JDBC standard enables you to use built-in data access wizards and other tools supporting rapid development. This article shows how to connect to SAP Netweaver Gateway data in NetBeans. You will create a connection and edit and save SAP Netweaver Gateway data in the Table Editor.

Create a JDBC Data Source for SAP Netweaver Gateway in NetBeans

To create the JDBC data source, expand the Database node in the Service window, right-click the Drivers node, and select New Driver. In the New Driver wizard that results, enter the following information:

  • Driver File(s): Click Add and, in the file explorer dialog that appears, select the cdata.jdbc.sapgateway.jar file. The driver JAR is located in the lib subfolder of the installation directory.
  • Driver Class: Click Find to search for the driver class inside the JAR. Then select cdata.jdbc.sapgateway.SAPGatewayDriver from the menu.
  • Name: Enter the name for the driver.

Define Connection Parameters

Follow the steps below to define required connection properties:

  1. In the Service window, right-click the Database node and click New Connection.

  2. In the New Connection Wizard, enter the following connection properties:

    • Driver Name: In the menu, select the CData JDBC Driver for SAP Netweaver Gateway.
    • User Name: Enter the username. This can also be defined in the JDBC URL.
    • Password: Enter the password. This can also be defined in the JDBC URL.
    • JDBC URL: Specify the JDBC URL.

      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 the following:

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

Query SAP Netweaver Gateway Data

To connect to SAP Netweaver Gateway data, right-click the connection in the Database node and click Connect. After the connection is established, you can expand it to discover schema information.

To load a table in the Data Views window, right-click the table and then click View Data. You can also insert, update, or delete records in the Data Views window.
