Connect to Templated Data from a Connection Pool in Jetty

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

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

   To authenticate to Templated, you will need an API key. You can obtain your API key from the Templated Dashboard under the API Key tab (app.templated.io > Dashboard > API Key).

   Using API Key Authentication

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Templated API key.

   Example connection string:

   Profile=C:\profiles\Templated.apip;AuthScheme=APIKey;ProfileSettings='APIKey=my_api_key';
   

4. Configure the resource in the Web.xml:

   
     jdbc/templateddb
     javax.sql.DataSource
     Container
   
   

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

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

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.
