I had the same problem and converting the .zip to a .jar worked. I reviewed
the documentation and I could not find any mention of zip files. Does the
absence of info on zip files imply they are not supported?
Yep, in terms of what any web container is supposed to support in
/WEB-INF/lib (and Tomcat applies the same rules to its shared lib
directories).
Zip files still work on a CLASSPATH for standard Java applications,
because they were in existence from JDK 1.0 days -- before there was such
a thing as a JAR file. But that still doesn't do you any good on either
3.3 or 4.0, because they both ignore your CLASSPATH ...
I think the Tomcat 3.3 and 4.0 documentation should be updated to explicitly
state that zip files and not supported by the servlet spec and therefore
must be converted to jar files and stored in the /lib directory.
I disagree.
The list of things that are *not* supported is close to infinite :-).
You'd be much better off making the starting assumption that anything not
mentioned is not supported. The only time you'll be wrong is when a
feature hasn't been documented yet.
And, even with it documented, it would still be one of the top 5
questions on TOMCAT-USER, just like it is today. The mailing list
archives are full of the answer to this question -- along with a lot of
questions that *are* answered in the docs -- so it wouldn't help much
anyway.

Tomcat4.0:-java.lang.ClassNotFoundException:oracle.jdbc.driver.OracleDrive
r..
hi all,
while I am running my web application with Tomcat4.0(Catalina) in accessing
database queries.It is showing java.lang.ClassNotFoundException:
oracle.jdbc.driver.OracleDriver..
I am using classes12.zip driver ..I have already set classpath for the
same..And with Tomcat3.2 my application is running well. Only with Tomcat4.0
getting this problem.I am trying to upgrade for Tomcat4.0.
In this case any thing I have to edit or set properties in server.xml. or
some where else. Or this relate with Realms.
If any one having idea about this plz pass this.
You need to do two things:
* Read the class-loader-howto.html documentation, and you'll see that
Tomcat recognizes only JAR files, not ZIP files. Rename classes12.zip
to classes12.jar and it should work.
* Complain to Oracle that they should package their JDBC drivers as
JAR files.
Regards
Sachin
