Connect to Splunk Data from a Connection Pool in Jetty

The Splunk JDBC Driver supports connection pooling: This article shows how to connect faster to Splunk data from Web apps in Jetty.

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

    <Configure id='splunkdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="splunkdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="splunkdemo"/></Arg> <Arg>jdbc/splunkdb</Arg> <Arg> <New class="cdata.jdbc.splunk.SplunkDriver"> <Set name="url">jdbc:splunk:</Set> <Set name="user">MyUserName</Set> <Set name="password">MyPassword</Set> <Set name="URL">MyURL</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

    To authenticate requests, set the User, Password, and URL properties to valid Splunk credentials. The port on which the requests are made to Splunk is port 8089.

    The data provider uses plain-text authentication by default, since the data provider attempts to negotiate TLS/SSL with the server.

    If you need to manually configure TLS/SSL, see Getting Started -> Advanced Settings in the data provider help documentation.

  4. Configure the resource in the Web.xml:

    jdbc/splunkdb javax.sql.DataSource Container
  5. You can then access Splunk with a lookup to java:comp/env/jdbc/splunkdb: InitialContext ctx = new InitialContext(); DataSource mysplunk = (DataSource)ctx.lookup("java:comp/env/jdbc/splunkdb");
