Connect Amazon Athena to IBM WebSphere Using the CData JDBC Driver

IBM WebSphere is a powerful application server that runs many enterprise level Java applications and services. When paired with the CData JDBC Driver for Amazon Athena, IBM WebSphere applications can connect to Amazon Athena and work with data using standard SQL queries instead of complex APIs. This simplifies integration, reduces development effort, and provides secure, real-time access to critical business data.

Getting Started

---

Prerequisites

1. Access to a Amazon Athena account (with API permissions)
2. IBM WebSphere Application Server (configured and running)
3. CData JDBC Driver for Amazon Athena
4. Java Servlet WAR application ready for deployment

Note: This article uses Salesforce as a demonstration data source, but the same steps can be followed to connect to any of the 250+ JDBC Drivers available in our portfolio.

Getting Started

Step 1: Download and install the CData JDBC Driver for Amazon Athena

Download and install the CData JDBC Driver for Amazon Athena, which provides a .jar file: cdata.jdbc.amazonathena.jar

Step 2: Install and configure IBM Websphere

1. Create an account in IBM WebSphere using the official IBM site.
2. Install and configure the IBM Websphere Application server in the local system using the documentation: IBM Websphere Application Server
3. Once the application server is installed, start the WebSphere Server using the Admin Console in your browser: https://your-server:9043/ibm/console

Step 3: Set up the JDBC provider and data source for Amazon Athena

1. Go to Resources, expand the JDBC section, and then select JDBC providers to create a new provider

2. Select the appropriate scope from the drop down menu

3. Click New to add a JDBC provider
• Choose User defined as the database type
• Enter cdata.jdbc.amazonathena.AmazonAthenaConnectionPoolDataSource as the implementation class name
• Type a name for the provider, for example User defined JDBC Provider
• Enter the full path of the JDBC driver JAR file in the classpath field
• Click Next, then Finish, and save the changes to the master configuration.

4. Once the JDBC provider is created, add a JDBC data source.
• Enter the basic details such as Data Source Name and JNDI name
• Select the existing JDBC provider created earlier (e.g., CData Amazon Athena Provider)
• Provide the Implementation class name: cdata.jdbc.amazonathena.AmazonAthenaConnectionPoolDataSource
• Add the Data Store Helper Class Name: com.ibm.websphere.rsadapter.GenericDataStoreHelper
• Configure security by setting authentication aliases if required
• Review the Summary page to verify all details and click Finish to complete the data source creation

5. Select the newly created data source from the list and open Custom properties
6. Add the JDBC connection string under the URL property and press OK. For example:

   jdbc:amazonathena:RTK=5246...;AWSAccessKey='a123';AWSSecretKey='s123';AWSRegion='IRELAND';Database='sampledb';S3StagingDirectory='s3://bucket/staging/';

   Authenticating to Amazon Athena

   To authorize Amazon Athena requests, provide the credentials for an administrator account or for an IAM user with custom permissions: Set AccessKey to the access key Id. Set SecretKey to the secret access key.

   Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.

   Obtaining the Access Key

   To obtain the credentials for an IAM user, follow the steps below:

   1. Sign into the IAM console.
   2. In the navigation pane, select Users.
   3. To create or manage the access keys for a user, select the user and then select the Security Credentials tab.

   To obtain the credentials for your AWS root account, follow the steps below:

   1. Sign into the AWS Management console with the credentials for your root account.
   2. Select your account name or number and select My Security Credentials in the menu that is displayed.
   3. Click Continue to Security Credentials and expand the Access Keys section to manage or create root account access keys.

   Authenticating from an EC2 Instance

   If you are using the CData Data Provider for Amazon Athena 2018 from an EC2 Instance and have an IAM Role assigned to the instance, you can use the IAM Role to authenticate. To do so, set UseEC2Roles to true and leave AccessKey and SecretKey empty. The CData Data Provider for Amazon Athena 2018 will automatically obtain your IAM Role credentials and authenticate with them.

   Authenticating as an AWS Role

   In many situations it may be preferable to use an IAM role for authentication instead of the direct security credentials of an AWS root user. An AWS role may be used instead by specifying the RoleARN. This will cause the CData Data Provider for Amazon Athena 2018 to attempt to retrieve credentials for the specified role. If you are connecting to AWS (instead of already being connected such as on an EC2 instance), you must additionally specify the AccessKey and SecretKey of an IAM user to assume the role for. Roles may not be used when specifying the AccessKey and SecretKey of an AWS root user.

   Authenticating with MFA

   For users and roles that require Multi-factor Authentication, specify the MFASerialNumber and MFAToken connection properties. This will cause the CData Data Provider for Amazon Athena 2018 to submit the MFA credentials in a request to retrieve temporary authentication credentials. Note that the duration of the temporary credentials may be controlled via the TemporaryTokenDuration (default 3600 seconds).

   Connecting to Amazon Athena

   In addition to the AccessKey and SecretKey properties, specify Database, S3StagingDirectory and Region. Set Region to the region where your Amazon Athena data is hosted. Set S3StagingDirectory to a folder in S3 where you would like to store the results of queries.

   If Database is not set in the connection, the data provider connects to the default database set in Amazon Athena.

   Built-in Connection String Designer

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

         java -jar cdata.jdbc.amazonathena.jar
         

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

   

   Note: If the URL property is not available, create it and then add the JDBC connection string.

   Tip: Always test the connection string with the driver before entering it in the URL property.
7. Now open the data source and choose Test Connection

Step 4: Build the web application

1. Build the web application using preferred Java framework (Servlet, JSP, or Spring). The resulting .war file will typically follow a structure like this:

		Amazon AthenaServletApp.war
		|--webcontent
		|  |--index.jsp                 -- JSP page (entry point)
		|  |
		|  |--WEB-INF/                  --Hidden from direct browser access
		|     |--web.xml                 -- Deployment descriptor
		|     |
		|     |--classes/                  --Compiled .class files
		|       |--com/example/Amazon Athena/
		|          |--Amazon AthenaServlet.class
		|
		|--lib/                      --Dependency JARs
		|--cdata.jdbc.athena.jar
	

2. Define the data access logic using JDBC or JPA, referencing the data source through a JNDI name
3. This article walks through JDBC connection setup and deploying a Java Servlet application
4. Package the project as a WAR (Web Application Archive) or EAR (Enterprise Archive) file for deployment
• In a terminal compile the java file using the command:

  			cd webcontent
  			jar cvf ..\Amazon AthenaServletApp.war *
  		

Step 5: Deploy the Amazon Athena application in WebSphere

1. In the WebSphere admin console, go to Applications and select Install New Application
2. Browse and upload the WAR file, then continue with the installation wizard.

Step 6: Retrieve Amazon Athena data through WebSphere

1. Access the application using its context root: http://hostname:port/context-root/page
Note: Ensure the deployed application is started before opening it in the browser.

We can now view the retrieved data from the source. The data is accessible directly through IBM WebSphere. This setup demonstrates how a servlet can be deployed in WebSphere to retrieve Amazon Athena data using the JDBC driver, creating a strong foundation for building advanced Amazon Athena powered enterprise applications.
