Subject: Load oracle.jdbc.driver.OracleDriver class
Hi!
I just upgraded from tomcat 4.0.3 to 5.5.9, I put all my librarie in
shared/lib and set correctly the CLASSPATH, but when I try to load the class
oracle.jdbc.driver.OracleDriver
tomcat return this error
ava.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

Do you have any suggestion??
I try this code
try { Class.forName ("oracle.jdbc.OracleDriver"); } catch (Exception ex) {}
and works fine.
Thanks
