Configure the CData JDBC Driver for Azure Management in a Connection Pool in Tomcat

Connect to Azure Management data from a connection pool in Tomcat.

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Azure Management data from a connection pool in Tomcat.

Connect to Azure Management Data through a Connection Pool in Tomcat

  1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
  2. Add a definition of the resource to the context. Specify the JDBC URL here.

    Azure Data Management uses the OAuth 2 authentication standard. See the Getting Started section of the CData driver documentation for a guide.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.azuredatamanagement.jar

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

    You can see the JDBC URL specified in the resource definition below.

    <Resource name="jdbc/azuredatamanagement" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.azuredatamanagement.AzureDataManagementDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:azuredatamanagement:InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access Azure Management data, add the code above to the context.xml in the application's META-INF directory.

    For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Azure Management for all applications.

  3. Add a reference to the resource to the web.xml for the application. Azure Management data JSP jdbc/AzureDataManagement javax.sql.DataSource Container
  4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/AzureDataManagement"); Connection conn = ds.getConnection();

The steps above show how to connect to Azure Management data in a simple connection pooling scenario. For more use cases and information, see the JNDI Datasource How-To in the Tomcat documentation.
