How to set CLASSPATH in Tomcat ?

[CodeLover55]

I installed Tomcat4.0.6 and don't know how to set the classpath. I've the classpath set as an environment system variable but I dunno why Tomcat is able to find classes in that path. As a workaround, I had to copy the classes in the classes directory of tomcat.
Also, I get a
ClassNotFoundException: oracle.jdbc.driver.OracleDriver
error when I run a JSP which has to connect to an Oracle database. I am sure this is happening bcoz Tomcat is not able to find the Oracle driver classes even though they are in the system variable CLASSPATH.

Please help.

FYI, I have been able to fix the jdbc driver problem. I had to copy the classes12.zip file from the oracle home directory to %CATALINA_HOME%/common/lib directory and also had to rename it to classes12.jar !!!!!!!!
