Tomcat 3.3 and Oracle9i
Hi!
I had tested a Java application that runs in Tomcat 3.3 accesing to
Oracle 8.1.7 with great success.
But now I'm trying to migrate the same application to a new server that
has the Oracle 9.0.1 version installed, and it doesn't get connected to
the database.
It gets the java.lang.NullPointerException. because the Connection
variable is always null.
I have updated the oracle jdbc version, so I can't understand why it
doesn't get connected yet, and I had recompiled all the classes.
Any ideas?
Thanks in advance.
Nancy.

Oracle 8 jar doesn't work with oracle 9.. Connections will always
fail until you either patch your classes12.zip or get the ojdbc14.jar
Drivers from oracle.

Obviously, Tomcat 3.3 hasn't changed ;-). I can't see any reason why
replacing the "Oracle 8" jar with the "Oracle 9" jar wouldn't work. If
you can post more information on your config (e.g. where the Oracle jar
is located), and any errors in the logs, it would help the list to help
you :).

Are you sure the new jdbc drivers are used?
Right here I've got oracle 9i connected to my
webapp running on tomcat 4.1.17 with the ojdbc14.jar
jdbc driver.
