Connect to Azure DevOps Data from a Connection Pool in Jetty

The CData JDBC driver for Azure DevOps is easy to integrate with Java Web applications. This article shows how to efficiently connect to Azure DevOps data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Azure DevOps 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 DevOps data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   <Configure id='azuredevopsdemo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="azuredevopsdemo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="azuredevopsdemo"/></Arg>
    <Arg>jdbc/azuredevopsdb</Arg>
    <Arg>
    <New class="cdata.jdbc.azuredevops.AzureDevOpsDriver">
    <Set name="url">jdbc:azuredevops:</Set>
    <Set name="AuthScheme">Basic</Set>
    <Set name="Organization">MyAzureDevOpsOrganization</Set>
    <Set name="ProjectId">MyProjectId</Set>
    <Set name="PersonalAccessToken">MyPAT</Set>
    <Set name="InitiateOAuth">GETANDREFRESH</Set>
    </New>
    </Arg>
    </New>
   </Configure>
   

   You can connect to your Azure DevOps account by providing the Organization and PersonalAccessToken.

   Obtaining a Personal Access Token

   A PersonalAccessToken is necessary for account authentication.

   To generate one, log in to your Azure DevOps Organization account and navigate to Profile -> Personal Access Tokens -> New Token. The generated token will be displayed.

   If you wish to authenticate to Azure DevOps using OAuth refer to the online Help documentation for an authentication guide.

4. Configure the resource in the Web.xml:

    jdbc/azuredevopsdb
    javax.sql.DataSource
    Container
   
   

5. You can then access Azure DevOps with a lookup to java:comp/env/jdbc/azuredevopsdb:

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

The steps above show how to configure the driver in a simple connection pooling scenario. For more use cases and information, see the Working with Jetty JNDI chapter in the Jetty documentation.
