I am using Tomcat v5.0 and Oracle 9i. Can anyone tell me why I am getting the exception given below...

I have added this to server.xml :

<Resource name="jdbc/ConnectionPool" auth="Container" type="javax.sql.DataSource"/>

<ResourceParams name="jdbc/ConnectionPool">
        <parameter>
    <name>factory</name>
    <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
  </parameter>
  <parameter>
    <name>driverClassName</name>
    <value>oracle.jdbc.driver.OracleDriver</value>
  </parameter>
  <parameter>
    <name>url</name>
    <value>jdbc:oracle:thin:@130.70.152.135:1521:ORCLDEV</value>
  </parameter>
  <parameter>
    <name>username</name>
    <value>vishnu</value>
  </parameter>
  <parameter>
    <name>password</name>
    <value>[my password]</value>
  </parameter>
  <parameter>
    <name>maxActive</name>
    <value>20</value>
  </parameter>
  <parameter>
    <name>maxIdle</name>
    <value>10</value>
  </parameter>
  <parameter>
    <name>maxWait</name>
    <value>-1</value>
  </parameter>
</ResourceParams>

I am getting this exception:
