I am trying to connect to Mysql from Jsp in Tomcat and I am getting Java.lang.NullPointer Exception. Please provide any help as soon as possible.

I have set the web.xml and the server.xml properly.

My web.xml contains:

<description>MySQL Test App</description>
		  <description>DB Connection</description>

server.xml I have added this:

<Context path="/become3" docBase="become3"
			debug="5" reloadable="true" crossContext="true">

	  <Logger className="org.apache.catalina.logger.FileLogger"
				 prefix="localhost_become3_log." suffix=".txt"

	  <Resource name="jdbc/TestDB"

	  <ResourceParams name="jdbc/TestDB">

		<!-- 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.

		<!-- Maximum number of idle dB connections to retain in pool.
			 Set to 0 for no limit.

		<!-- Maximum time to wait for a dB connection to become available
