Connect to Suadeo Data from a Connection Pool in Jetty

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

   
   <Configure id='suadeodemo' class="org.eclipse.jetty.webapp.WebAppContext">
       <New id="suadeodemo" class="org.eclipse.jetty.plus.jndi.Resource">
       <Arg><Ref refid="suadeodemo"/></Arg>
       <Arg>jdbc/suadeodb</Arg>
       <Arg>
         <New class="cdata.jdbc.suadeo.SuadeoDriver">
           <Set name="url">jdbc:suadeo:</Set>
           <Set name="URL">https://mysuadeoinstance</Set>
           <Set name="User">username</Set>
           <Set name="Password">password</Set>
           <Set name="AuthenticationName">your_auth_name</Set>
         </New>
       </Arg>
     </New>
   </Configure>
   

   The driver uses the OAuth 2.0 Resource Owner Password Credentials (ROPC) grant to authenticate to Suadeo. Authentication occurs directly using your credentials; there is no browser-based authorization flow or refresh token.

   Set the following connection properties:

   • URL: The base URL of your Suadeo instance.
   • User: Your Suadeo username.
   • Password: Your Suadeo password.
   • AuthenticationName: The name identifier for the authentication configuration in your Suadeo instance. Different authentication names can be configured for different environments or use cases.

   When you connect, the driver sends your credentials to the Suadeo OAuth token endpoint, receives an access token, and uses it for all subsequent requests. A new access token is obtained automatically when needed during the session.

4. Configure the resource in the Web.xml:

   
     jdbc/suadeodb
     javax.sql.DataSource
     Container
   
   

5. You can then access Suadeo with a lookup to java:comp/env/jdbc/suadeodb:

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

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.
