Connect to MariaDB Data from a Connection Pool in Jetty

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

   <Configure id='mariadbdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="mariadbdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="mariadbdemo"/></Arg> <Arg>jdbc/mariadbdb</Arg> <Arg> <New class="cdata.jdbc.mariadb.MariaDBDriver"> <Set name="url">jdbc:mariadb:</Set> <Set name="User">myUser</Set> <Set name="Password">myPassword</Set> <Set name="Database">NorthWind</Set> <Set name="Server">myServer</Set> <Set name="Port">3306</Set> </New> </Arg> </New> </Configure>

   The Server and Port properties must be set to a MariaDB server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, the tables from all databases are reported.

4. Configure the resource in the Web.xml:

   jdbc/mariadbdb javax.sql.DataSource Container

5. You can then access MariaDB with a lookup to java:comp/env/jdbc/mariadbdb: InitialContext ctx = new InitialContext(); DataSource mymariadb = (DataSource)ctx.lookup("java:comp/env/jdbc/mariadbdb");
