Connect to Google Calendar Data from a Connection Pool in Jetty


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

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

    <Configure id='googlecalendardemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="googlecalendardemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="googlecalendardemo"/></Arg> <Arg>jdbc/googlecalendardb</Arg> <Arg> <New class="cdata.jdbc.googlecalendar.GoogleCalendarDriver"> <Set name="url">jdbc:googlecalendar:</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

    You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

  4. Configure the resource in the Web.xml:

    jdbc/googlecalendardb javax.sql.DataSource Container

  5. You can then access Google Calendar with a lookup to java:comp/env/jdbc/googlecalendardb: InitialContext ctx = new InitialContext(); DataSource mygooglecalendar = (DataSource)ctx.lookup("java:comp/env/jdbc/googlecalendardb");

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.
