Hi List,

	I am trying to execute a servlet program using Apache-TOMCAT. I am
using Oracle as back end data base. When I try to execute this servelet I am
getting following error

Error: 500
Location: /examples/servlet/Employee
Internal Servlet Error:
java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver
	at 
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:740)
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)

org.apache.tomcat.service.TcpConnectionThread.run(SimpleTcpEndpoint.java:338
)
	at java.lang.Thread.run(Thread.java:475)


	Tomcat is not getting the OraceDriver eventhough it is very much
there in my CLASSPATH. How to add this to TOMCAT CLASSPATH?
