There are several ways to configure a Tomcat data source.

  1. Configuring a data source using JNDI (Java Naming and Directory Interface) in Tomcat.
  2. In the context.xml file located in the conf directory of Tomcat, you can define a data source using either the Resource element or the ResourceLink element.
  3. Configure a data source reference in the web.xml file located in the WEB-INF directory of the web application, using the resource-ref element to refer to the data source defined in the context.xml file.
  4. Setting up Tomcat’s built-in connection pool (Tomcat JDBC Connection Pool) configuration.
  5. Configure the data source in the context.xml file located in the conf directory of Tomcat using the Resource element, specifying the type attribute as javax.sql.DataSource.
  6. Configure a data source reference in the web.xml file in the WEB-INF directory of a web application, using the resource-ref element to refer to the data source defined in the context.xml.
  7. Configuration using third-party connection pools such as Apache Commons DBCP or C3P0.
  8. Configure the data source in the context.xml file under the conf directory of Tomcat, using the Resource element to define the data source and specifying the type attribute as the implementation class of the third-party connection pool data source.
  9. Configure a data source reference in the web.xml file located in the WEB-INF directory of a web application, using the resource-ref element to reference the data source defined in context.xml.

The above is the common way of configuring a data source in Tomcat. Choose the appropriate configuration method based on your actual needs and the connection pool you are using.
