Google Cloud Storage JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Google Cloud Storage.



Integrate Google Cloud Storage data into Java servlets: Use the Management Console in JBoss to install the Google Cloud Storage JDBC Driver.

CData JDBC drivers can be configured in JBoss by following the standard procedure for connection pooling. This article details how to access Google Cloud Storage data from a connection pool in JBoss applications. This article details how to use the JBoss Management Interface to configure the CData JDBC Driver for Google Cloud Storage. You will then access Google Cloud Storage data from a connection pool.

Create a JDBC Data Source for Google Cloud Storage from the Management Console

Follow the steps below to add the driver JAR and define required connection properties.

  1. In the Runtime menu, select the Domain or Server menu, depending on whether you are deploying to a managed domain or to a stand-alone server, and click "Manage deployments" to open the Deployments page.
  2. Click Add. In the resulting wizard, add the JAR file and license for the driver, located in the lib subfolder of the installation directory. Finish the wizard with the defaults, select the driver, and click Enable.
  3. In the Configuration menu, click Subsystems -> Connector -> Datasources. This opens the JDBC Datasources page.
  4. Click Add and, in the resulting wizard, enter a name for the driver and the JNDI name. For example: java:jboss/root/jdbc/GoogleCloudStorage
  5. Select the driver that you added above.
  6. Enter the JDBC URL and the username and password. The syntax of the JDBC URL is jdbc:googlecloudstorage: followed by a semicolon-separated list of connection properties.

    Authenticate with a User Account

    You can connect without setting any connection properties for your user credentials. After setting InitiateOAuth to GETANDREFRESH, you are ready to connect.

    When you connect, the Google Cloud Storage OAuth endpoint opens in your default browser. Log in and grant permissions, then the OAuth process completes

    Authenticate with a Service Account

    Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes.

    You need to create an OAuth application in this flow. See the Help documentation for more information. After setting the following connection properties, you are ready to connect:

    • InitiateOAuth: Set this to GETANDREFRESH.
    • OAuthJWTCertType: Set this to "PFXFILE".
    • OAuthJWTCert: Set this to the path to the .p12 file you generated.
    • OAuthJWTCertPassword: Set this to the password of the .p12 file.
    • OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
    • OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
    • OAuthJWTSubject: Set this to your enterprise Id if your subject type is set to "enterprise" or your app user Id if your subject type is set to "user".
    • ProjectId: Set this to the Id of the project you want to connect to.

    The OAuth flow for a service account then completes.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Google Cloud Storage JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.googlecloudstorage.jar

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

    A typical connection string is below:

    jdbc:googlecloudstorage:ProjectId='project1';InitiateOAuth=GETANDREFRESH
  7. Test the connection and finish the wizard. Select the Google Cloud Storage data source and click Enable.
