Connect to xBase Data from a Connection Pool in Jetty

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

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

    <Configure id='xbasedemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="xbasedemo" class=""> <Arg><Ref refid="xbasedemo"/></Arg> <Arg>jdbc/xbasedb</Arg> <Arg> <New class="cdata.jdbc.xbase.xBaseDriver"> <Set name="url">jdbc:xbase:</Set> <Set name="DataSource">MyDBFFilesFolder</Set> </New> </Arg> </New> </Configure>

    The DataSource property must be set to the name of the folder that contains the .dbf files. Specify the IncludeFiles property to work with xBase table files having extensions that differ from .dbf. Specify multiple extensions in a comma-separated list.

  4. Configure the resource in the Web.xml:

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

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.
