Connect to Facebook Data from a Connection Pool in Jetty

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

   <Configure id='facebookdemo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="facebookdemo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="facebookdemo"/></Arg>
    <Arg>jdbc/facebookdb</Arg>
    <Arg>
    <New class="cdata.jdbc.facebook.FacebookDriver">
    <Set name="url">jdbc:facebook:</Set>
    <Set name="InitiateOAuth">GETANDREFRESH</Set>
    </New>
    </Arg>
    </New>
   </Configure>
   

   Most tables require user authentication as well as application authentication. Facebook uses the OAuth authentication standard. To authenticate to Facebook, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can obtain your own by registering an app with Facebook.

   See the Getting Started chapter of the help documentation for a guide to using OAuth.

4. Configure the resource in the Web.xml:

    jdbc/facebookdb
    javax.sql.DataSource
    Container
   
   

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

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