Connect to Codat Data from a Connection Pool in Jetty

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

   <Configure id='codatdemo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="codatdemo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="codatdemo"/></Arg>
    <Arg>jdbc/codatdb</Arg>
    <Arg>
    <New class="cdata.jdbc.api.APIDriver">
    <Set name="url">jdbc:api:</Set>
    <Set name="Profile">C:\profiles\Codat.apip</Set>
    <Set name="ProfileSettings">'APIKey</Set>
    </New>
    </Arg>
    </New>
   </Configure>
   

   Start by setting the Profile connection property to the location of the Codat Profile on disk (e.g. C:\profiles\Codat.apip). Next, set the ProfileSettings connection property to the connection string for Codat (see below).

   Codat API Profile Settings

   Log into the Codat Portal, navigate to Accounts > Profile > API Key to obtain your API key.

4. Configure the resource in the Web.xml:

    jdbc/codatdb
    javax.sql.DataSource
    Container
   
   

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

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