Twitter JDBC Driver

A straightforward interface to connect any Java application with Twitter integration capabilities including Search, GeoSearch, UserInfo, DirectMessages, Followers, and more!

The Twitter JDBC Driver supports connection pooling: This article shows how to connect faster to Twitter data from Web apps in Jetty.

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

    <Configure id='twitterdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="twitterdemo" class=""> <Arg><Ref refid="twitterdemo"/></Arg> <Arg>jdbc/twitterdb</Arg> <Arg> <New class="cdata.jdbc.twitter.TwitterDriver"> <Set name="url">jdbc:twitter:</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

    All tables require authentication. You can connect using your User and Password or OAuth. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can register an app to obtain your own.

    If you intend to communicate with Twitter only as the currently authenticated user, then you can obtain the OAuthAccessToken and OAuthAccessTokenSecret directly by registering an app.

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

  4. Configure the resource in the Web.xml:

    jdbc/twitterdb javax.sql.DataSource Container
  5. You can then access Twitter with a lookup to java:comp/env/jdbc/twitterdb: InitialContext ctx = new InitialContext(); DataSource mytwitter = (DataSource)ctx.lookup("java:comp/env/jdbc/twitterdb");

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.
