Connect to FreshBooks Data from a Connection Pool in Jetty


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

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

    <Configure id='freshbooksdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="freshbooksdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="freshbooksdemo"/></Arg> <Arg>jdbc/freshbooksdb</Arg> <Arg> <New class="cdata.jdbc.freshbooks.FreshBooksDriver"> <Set name="url">jdbc:freshbooks:</Set> <Set name="CompanyName">CData</Set> <Set name="Token">token</Set> </New> </Arg> </New> </Configure>

    To connect to FreshBooks, you can set the CompanyName and Token connection properties. Alternatively, you can use the OAuth authentication standard.

    OAuth can be used to enable other users to access their own company data. To authenticate using OAuth, you will need to obtain the OAuthClientId and OAuthClientSecret by registering an app. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

  4. Configure the resource in the Web.xml:

    jdbc/freshbooksdb javax.sql.DataSource Container

  5. You can then access FreshBooks with a lookup to java:comp/env/jdbc/freshbooksdb: InitialContext ctx = new InitialContext(); DataSource myfreshbooks = (DataSource)ctx.lookup("java:comp/env/jdbc/freshbooksdb");
