Connect to Oracle HCM Cloud Data from a Connection Pool in Jetty

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

   <Configure id='oraclehcmdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="oraclehcmdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="oraclehcmdemo"/></Arg> <Arg>jdbc/oraclehcmdb</Arg> <Arg> <New class="cdata.jdbc.oraclehcm.OracleHCMDriver"> <Set name="url">jdbc:oraclehcm:</Set> <Set name="Url">https://abc.oraclecloud.com</Set> <Set name="User">user</Set> <Set name="Password">password</Set> </New> </Arg> </New> </Configure>

   Using Basic Authentication

   You must set the following to authenticate to Oracle HCM Cloud:

   • Url: The Url of your account.
   • User: The user of your account.
   • Password: The password of your account.

4. Configure the resource in the Web.xml:

   jdbc/oraclehcmdb javax.sql.DataSource Container

5. You can then access Oracle HCM Cloud with a lookup to java:comp/env/jdbc/oraclehcmdb: InitialContext ctx = new InitialContext(); DataSource myoraclehcm = (DataSource)ctx.lookup("java:comp/env/jdbc/oraclehcmdb");

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.
