Connect to IBM Cloud Object Storage Data from a Connection Pool in JBoss

CData JDBC drivers can be configured in JBoss by following the standard procedure for connection pooling. This article details how to access IBM Cloud Object 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 IBM Cloud Object Storage. You will then access IBM Cloud Object Storage data from a connection pool.

Create a JDBC Data Source for IBM Cloud Object 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/IBMCloudObjectStorage
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:ibmcloudobjectstorage: followed by a semicolon-separated list of connection properties.

   Register a New Instance of Cloud Object Storage

   If you do not already have Cloud Object Storage in your IBM Cloud account, follow the procedure below to install an instance of SQL Query in your account:

   1. Log in to your IBM Cloud account.
   2. Navigate to the page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.

   Connecting using OAuth Authentication

   There are certain connection properties you need to set before you can connect. You can obtain these as follows:

   API Key

   To connect with IBM Cloud Object Storage, you need an API Key. You can obtain this as follows:

   1. Log in to your IBM Cloud account.
   2. Navigate to the Platform API Keys page.
   3. On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
   4. In the pop-up window, specify the API Key name and click "Create". Note the API Key as you can never access it again from the dashboard.

   Cloud Object Storage CRN

   If you have multiple accounts, you will need to specify the CloudObjectStorageCRN explicitly. To find the appropriate value, you can:

   • Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
   • Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, Under Storage, select your Cloud Object Storage resource to get its CRN.

   Connecting to Data

   You can now set the following to connect to data:

   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
   • ApiKey: Set this to your API key which was noted during setup.
   • CloudObjectStorageCRN (Optional): Set this to the cloud object storage CRN you want to work with. While the connector attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than Cloud Object Storage account.

   When you connect, the connector completes the OAuth process.

   1. Extracts the access token and authenticates requests.
   2. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.ibmcloudobjectstorage.jar

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

   A typical connection string is below:

   jdbc:ibmcloudobjectstorage:ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;
7. Test the connection and finish the wizard. Select the IBM Cloud Object Storage data source and click Enable.

More JBoss Integration

The steps above show how to configure the driver in a simple connection pooling scenario. For more information, refer to the Data Source Management chapter in the JBoss EAP documentation.
