Google Data Catalog JDBC Driver

Google Data Catalog データに連携するJava アプリケーションを素早く、簡単に開発できる便利なドライバー。



Use the CData JDBC Driver for Google Data Catalog to connect to Google Data Catalog data from Web applications running on WebLogic.

The CData JDBC Driver for Google Data Catalog enables you to follow standard procedures to integrate Google Data Catalog data into Java Web applications. This article shows how to deploy the CData JDBC Driver for Google Data Catalog in WebLogic server.

Install the JDBC Driver in WebLogic Server

Add the driver JAR and license file to the classpath your application will be using. The .lic file must be located in the same folder as the JAR. These files are located in the lib subfolder of the installation directory.

If you want to add the driver to all domains, add the JAR to the WEBLOGIC_CLASSPATH environment variable. add the following line to the commEnv.cmd/sh script in WL_HOME\common\bin\.

set WEBLOGIC_CLASSPATH=your-installation-directory\lib\cdata.jdbc.googledatacatalog.jar;%WEBLOGIC_CLASSPATH%

If you want to add the driver to a specific domain, you will need to add the JAR to the PRE_CLASSPATH environment variable. Add the following line to the setDomainEnv.cmd/sh script in the bin subfolder of the folder for that domain:

set PRE_CLASSPATH=your-installation-directory\lib\cdata.jdbc.googledatacatalog.jar;%PRE_CLASSPATH%

Create a JDBC Data Source for Google Data Catalog

After installing the driver, create the connection.

  1. In the Domain Structure tree, click Services -> Data Sources -> New -> Generic Data Source.
  2. On the JDBC Data Source Properties page, enter the following information:
    • Name: Enter a user-friendly name; for example, googledatacatalogjdbc.
    • JDBC Name: Enter the path the JDBC data source will be bound to; for example, jdbc/GoogleDataCatalog.
    • Database Type: Select Other.

  3. Click Next to use the default options. On the last page, enter the following information and click Test Configuration:

    • Driver Class Name: Enter the driver class, cdata.jdbc.googledatacatalog.GoogleDataCatalogDriver, in this property.
    • URL: Enter the JDBC URL. A typical JDBC URL is below:

      jdbc:googledatacatalog:ProjectId=YourProjectId;

      Google Data Catalog uses the OAuth authentication standard. Authorize access to Google APIs on behalf on individual users or on behalf of users in a domain.

      Before connecting, specify the following to identify the organization and project you would like to connect to:

      • OrganizationId: The ID associated with the Google Cloud Platform organization resource you would like to connect to. Find this by navigating to the cloud console.

        Click the project selection drop-down, and select your organization from the list. Then, click More -> Settings. The organization ID is displayed on this page.

      • ProjectId: The ID associated with the Google Cloud Platform project resource you would like to connect to.

        Find this by navigating to the cloud console dashboard and selecting your project from the Select from drop-down. The project ID will be present in the Project info card.

      When you connect, the OAuth endpoint opens in your default browser. Log in and grant permissions to the application to completes the OAuth process. For more information, refer to the OAuth section in the Help documentation.

    • Database User Name: Enter the username, if not specified in the JDBC URL.
    • Password: Enter the password, if not specified in the JDBC URL.

After selecting the server where you want to deploy the JDBC data source, you can now connect to Google Data Catalog data.

More WebLogic Integration

The steps above show how configure the driver in a simple connection pooling scenario. For more use cases and information, see the JDBC sections in the WebLogic Data Sources chapter of the Oracle Fusion Middleware documentation.
