How to Configure Tomcat for MySQL Database Connectivity Using JNDI or DriverManager?

Configuring Tomcat for MySQL Connectivity

MySQL Connector Placement

The location of the JDBC driver for MySQL, mysql-connector-java-5.1.13-bin, depends on the connection management method.

• JNDI Datasource: Place the JAR file in Tomcat/lib. This allows Tomcat to manage connections and access the driver.
• DriverManager Method: Place the JAR file in either Tomcat/lib (global access) or YourApp/WEB-INF/lib (per-webapp override).

Configuration Files

• JNDI Datasource:

  • Configure the datasource in YourApp/META-INF/context.xml.
  • Refer to the datasource in YourApp/WEB-INF/web.xml using a resource-env-ref.

• DriverManager Method:

  • Configure the connection parameters manually. No need for Tomcat configuration.

Web.XML File

A web.xml file is required to define web application components such as servlets, filters, and listeners. Place it under Tomcat 6.0webappsmyappWEB-INF.
