Correct path and Tomcat version. Add category link.

  The usual procedure requires the application developer to set up a !DataSource in the web application server, specifying the driver class, JDBC URL (connect string), username, password, and various pooling options. Then, the developer must reference the !DataSource in his application's web.xml configuration file, and then access it properly in his servlet or JSP. Particularly during development, setting all of this
  up is tedious and error-prone.

+ With Tomcat the process is vastly simplified. Tomcat allows you to configure !DataSources for your J2EE web application
  in a context.xml file that is stored in your web application project. You don't have to mess with configuring the !DataSource
  separately in the Tomcat server.xml, or referencing it in your application's web.xml file. Here's how:
  
  === Install the JDBC Driver ===
  
- Install the .jar file(s) containing the JDBC driver in Tomcat's common/lib folder. You do not need to put them in your application's WEB-INF/lib folder. When working with J2EE !DataSources, the web application server manages connections for your application.
