title: Getting java.lang.ClassNotFoundException: com.mysql.jdbc.Driver Exception
body: <p>I am getting Following Exception while configuring the Connection Pool in Tomcat</p>
  
  <p>This is Context.xml</p>
  
  <pre><code>&lt;Context path="/DBTest" docBase="DBTest"
          debug="5" reloadable="true" crossContext="true"&gt;
  
      &lt;!-- maxActive: Maximum number of dB connections in pool. Make sure you
           configure your mysqld max_connections large enough to handle
           all of your db connections. Set to -1 for no limit.
           --&gt;
  
      &lt;!-- maxIdle: Maximum number of idle dB connections to retain in pool.
           Set to -1 for no limit.  See also the DBCP documentation on this
           and the minEvictableIdleTimeMillis configuration parameter.
           --&gt;
  
      &lt;!-- maxWait: Maximum time to wait for a dB connection to become available
           in ms, in this example 10 seconds. An Exception is thrown if
           this timeout is exceeded.  Set to -1 to wait indefinitely.
           --&gt;
  
      &lt;!-- username and password: MySQL dB username and password for dB connections  --&gt;
  
      &lt;!-- driverClassName: Class name for the old mm.mysql JDBC driver is
           org.gjt.mm.mysql.Driver - we recommend using Connector/J though.
           Class name for the official MySQL Connector/J driver is com.mysql.jdbc.Driver.
           --&gt;
  
      &lt;!-- url: The JDBC connection url for connecting to your MySQL dB.
           --&gt;
