Oracle Drive and Tomcat 4

[Jack Li]

I installed Tomcat 4 and JDK 1.3 on a new server. I put oracle's
classes12.zip in "c:\jdk\bin\" and set 
 
CLASSPATH=c:\jdk\bin\;c:\jdk\bin\classes12.zip; 
 
When I call Oracle database, I got error message: Oracle Driver not found.
The same program on another server runs ok.
 
Any ideas?
 
Thanks,
Jack Li
