Connect to Azure Active Directory Data from a Connection Pool in Jetty

The CData JDBC driver for Azure Active Directory is easy to integrate with Java Web applications. This article shows how to efficiently connect to Azure Active Directory data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Azure Active Directory in Jetty.

Configure the JDBC Driver for Salesforce as a JNDI Data Source

Follow the steps below to connect to Salesforce from Jetty.

1. Enable the JNDI module for your Jetty base. The following command enables JNDI from the command-line:

   java -jar ../start.jar --add-to-startd=jndi
   

2. Add the CData and license file, located in the lib subfolder of the installation directory, into the lib subfolder of the context path.

3. Declare the resource and its scope. Enter the required connection properties in the resource declaration. This example declares the Azure Active Directory data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   <Configure id='azureactivedirectorydemo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="azureactivedirectorydemo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="azureactivedirectorydemo"/></Arg>
    <Arg>jdbc/azureactivedirectorydb</Arg>
    <Arg>
    <New class="cdata.jdbc.azuread.AzureADDriver">
    <Set name="url">jdbc:azuread:</Set>
    <Set name="OAuthClientId">MyApplicationId</Set>
    <Set name="OAuthClientSecret">MySecretKey</Set>
    <Set name="CallbackURL">http://localhost:33333</Set>
    <Set name="InitiateOAuth">GETANDREFRESH</Set>
    </New>
    </Arg>
    </New>
   </Configure>
   

   Azure Active Directory uses the OAuth authentication standard. To authenticate using OAuth, create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the OAuth section in the Help documentation for an authentication guide.

4. Configure the resource in the Web.xml:

    jdbc/azureactivedirectorydb
    javax.sql.DataSource
    Container
   
   

5. You can then access Azure Active Directory with a lookup to java:comp/env/jdbc/azureactivedirectorydb:

   InitialContext ctx = new InitialContext();
   DataSource myazureactivedirectory = (DataSource)ctx.lookup("java:comp/env/jdbc/azureactivedirectorydb");
