Connect to Oracle SCM Data from a Connection Pool in Jetty

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

   <Configure id='oraclescmdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="oraclescmdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="oraclescmdemo"/></Arg> <Arg>jdbc/oraclescmdb</Arg> <Arg> <New class="cdata.jdbc.oraclescm.OracleSCMDriver"> <Set name="url">jdbc:oraclescm:</Set> <Set name="Url">https://myinstance.oraclecloud.com</Set> <Set name="User">user</Set> <Set name="Password">password</Set> </New> </Arg> </New> </Configure>

   The following connection properties are required to connect to Oracle SCM data.

   • Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
   • User: The username of your Oracle Cloud service account.
   • Password: The password of your Oracle Cloud service account.

4. Configure the resource in the Web.xml:

   jdbc/oraclescmdb javax.sql.DataSource Container

5. You can then access Oracle SCM with a lookup to java:comp/env/jdbc/oraclescmdb: InitialContext ctx = new InitialContext(); DataSource myoraclescm = (DataSource)ctx.lookup("java:comp/env/jdbc/oraclescmdb");
