Have you told you'r servlet engine where to find it?
(If you need a servlet engine to run a jsp..)
In tomcat you add something like this to you'r server.xml file
<!-- Mysql Connection -->
          <Context path="/servlet" docBase="servlet" debug="5" reloadable="true" crossContext="true">
               <Logger className="org.apache.catalina.logger.FileLogger" prefix="localhost_Absence_log."
                              suffix=".txt" timestamp="true"/>
               <Resource name="jdbc/AbsenceDB" auth="Container" type="javax.sql.DataSource"/>
               <ResourceParams name="jdbc/AbsenceDB">
               <parameter>
                    <name>factory</name>
                    <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
               </parameter>
<!-- 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 0 for no limit.
     -->
               <parameter>
                         <name>maxActive</name>
                    <value>100</value>
               </parameter>
<!-- Maximum number of idle dB connections to retain in pool.
     Set to 0 for no limit.
-->
               <parameter>
                    <name>maxIdle</name>
                    <value>30</value>
               </parameter>
<!-- 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.
-->
               <parameter>
                    <name>maxWait</name>
                    <value>10000</value>
               </parameter>
<!-- MySQL dB username and password for dB connections -->
               <parameter>
                    <name>username</name>
                    <value>aUsername</value>
               </parameter>
               <parameter>
                    <name>password</name>
                    <value>aPassword</value>
               </parameter>
<!-- Class name for mm.mysql JDBC driver -->
               <parameter>
                    <name>driverClassName</name>
                    <value>com.mysql.jdbc.Driver</value>
               </parameter>
<!-- The JDBC connection url for connecting to your MySQL dB.
The autoReconnect=true argument to the url makes sure that the
mm.mysql JDBC Driver will automatically reconnect if mysqld closed the
connection. mysqld by default closes idle connections after 8 hours.
-->
               <parameter>
                    <name>url</name>
                    <value>jdbc:mysql://<address to the server>?autoReconnect=true</value>
               </parameter>
               </ResourceParams>
          </Context>
