How to configure Oracle Datasource in Tomcat

Question

Hello,
My configuration of a Tomcat Datasource (oracle) appears to be wrong. Either that or my oraclejdbc.jar file is in the wrong place. Perhaps my classpath setting is wrong. Any help is appreciated.
Tomcat console error:
20070423 20:46:22.514 http-8080-Processor24(0x005878d2)
JdbcUtil#getDataSourceObject() Throw com.waveset.util.ConfigurationError: Failed to load JDBC DataSource 'java:comp/env/jdbc/wrsPool':

thanks for the reply, i have configured the connection pool settings in the tomcat.
I created a class with static method, which will return the connection object.
whenever i need the connection object, iam invoking the static method, once its usage is over iam closing thew connection..
is it the right way of using the connection object in the web application.
