Connect to Greenhouse Data from a Connection Pool in Jetty

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

   <Configure id='greenhousedemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="greenhousedemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="greenhousedemo"/></Arg> <Arg>jdbc/greenhousedb</Arg> <Arg> <New class="cdata.jdbc.greenhouse.GreenhouseDriver"> <Set name="url">jdbc:greenhouse:</Set> <Set name="APIKey">YourAPIKey</Set> </New> </Arg> </New> </Configure>

   You need an API key to connect to Greenhouse. To create an API key, follow the steps below:

   1. Click the Configure icon in the navigation bar and locate Dev Center on the left.
   2. Select API Credential Management.
   3. Click Create New API Key.
   • Set "API Type" to Harvest.
   • Set "Partner" to custom.
   • Optionally, provide a description.
   4. Proceed to Manage permissions and select the appropriate permissions based on the resources you want to access through the driver.
   5. Copy the created key and set APIKey to that value.

4. Configure the resource in the Web.xml:

   jdbc/greenhousedb javax.sql.DataSource Container

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