I use classes12.jar with tomcat-4.0.3 and JDK1.4 (solaris) and have no
problems. classes12.jar is unmodified in common/lib, didn't have to
remove anything.

Hello John,

Well, I have been using the classes12.jar in TOMCAT_HOME/common/lib.
I've used it with both the JNDI javax.sql.DataSource deal provided by
the Jakarta-Commons project and another connection pooler.  I've never
had a single problem.  I've used JDK-1.3.x and JDK-1.4 and haven't had
to remove any classes from anywhere.  If you are having to do this
with Tomcat-4.0.3, I suggest an upgrade to the latest 4.0.4 or 4.1.x
betas.  They are plenty stable and fix some classloading issues.  I
pretty much skipped from Tomcat-4.0.2-b2 to nightly builds of 4.1
because of so many classloading issues with the final release of 4.0.2
(and 4.0.3 is just 4.0.2 + a security fix).

SOLVED: jdk 1.4 and Oracle drivers

[John Gregg]

Once I tapped in to the bootstrap process with my debugger a little earlier
in the Tomcat startup process, I could see the conditions under which some
jar files are excluded from the various class loaders.  The Oracle
classes12.jar file contains the javax.sql stuff, which is now included in
jdk 1.4.  Tomcat ignores any jar files that contain classes that were once
separate from the standard jdk but are now part of it, such as the jdbc
extensions, jndi stuff, etc.  The solution was simply to remove the
javax.sql stuff from the Oracle clsses12.jar file.

Hi all.

Upon completing my most recent project I switched from jdk 1.3.1 to 1.4.
However now I can't start Tomcat (4.0.1) because it can't find the Oracle
jdbc driver class.  When I first started using Oracle with Tomcat, I renamed
the classes12.zip to classes12.jar.  Now no matter where I put
classes12.jar, I get the same error.  I've tried lib, common/lib,
server/lib, and webapps//web-inf/lib.  FWIW, I have a servlet that
runs at startup and tries to initialize a db connection pool.  This used to
work just fine and in fact still does with postgresql.jar.  I even tried
unzipping classes12.zip and actually jarring it up.  No luck.  I've traced
the problem in a debugger far enough to know that the StandardClassLoader
that should have classes12.jar in its scope doesn't.  In fact, of all the
stuff under common (classes and lib), it's missing classes12.jar and
jdbc2_0-stdext.jar.  Everything else is there.  I see those 2 jars overlap
somewhat, so I tried removing the latter to no avail.  I don't have any
other Tomcat installations and there aren't any jar files in multiple
locations.  I feel like I know everything about this problem but the answer.

thanks

john
