Btrieve JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Pervasive SQL (Btrieve) databases.

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

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

    <Configure id='btrievedemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="btrievedemo" class=""> <Arg><Ref refid="btrievedemo"/></Arg> <Arg>jdbc/btrievedb</Arg> <Arg> <New class="cdata.jdbc.btrieve.BtrieveDriver"> <Set name="url">jdbc:btrieve:</Set> <Set name="User">myuser</Set> <Set name="Password">mypassword</Set> <Set name="Server">myserver</Set> <Set name="Database">mydatabase</Set> </New> </Arg> </New> </Configure>

    The PSQL v13 client will need to be installed on the same machine as the driver. To connect, set the User, Password, Server, and Database properties.

  4. Configure the resource in the Web.xml:

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

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.
