RE: JDBC & Tomcat / JAR's
with the final release of 3.1 I've had no problems with Tomcat recognising
JAR files in the ./lib directory - without any need to expand them or
explicitly name them. I have had some problems with ZIP files though.
I think that you are using the wrong lib directory.
The /opt/tomcat/lib directory is tomcat's own library directory. The one for
servlet specific jar's is located inside the webapp -
ie. ./WEB-INF/lib jar's placed in this directory are automatically added to
the classpath.
But strangely not zip files ....

Hi,
just to clarify slighty, I think if the JDBC (or any other) classes that you
want to include are in a JAR file, then you need to explicity specify the
JAR file in the CLASSPATH environment variable that Tomcat sees, i.e.
export CLASSPATH = ${CLASSPATH}:/usr/local/mysql/jdbc/drivers.jar (or
whatever)
But if the class files are not in a JAR file (or you choose to unpack them
from the JAR file) then placing them in /opt/tomcat/lib will automatically
make them included, as /opt/tomcat/lib is already in CLASSPATH, but you must
preserve the directory structure as in the JAR file, so for example the
class org.gjt.mm.mysql.Driver would be in
/opt/tomcat/lib/org/gjt/mm/mysql/Driver.class
Hope this helps,
Giles

You can put them them where you want, as long as you include them in the
CLASSPATH.

Just to nit-pick, the WEB-INF/lib directory itself is *not* put in the class
path, but individual JAR files (not ZIP files) within the directory *are* put in
the class path. The WEB-INF/classes directory as a whole (for classes that are
not archived) is also added.
These rules are based on the requirements of the servlet spec (version 2.2), and
are portable to all conforming servlet containers.

I tried it, as well as unpacking the zip file and repacking it as a jar. I
ended up unziping the directory structure and moving it into the classes
directory under the webapp. That worked.
It was almost as if the webapp/WEB-INF/lib directory was not really in the
CLASSPATH. ( Tomcat 3.1 )
