A few ideas...
You could write a plugin (or perhaps leverage maven-dependency-plugin
and/or maven-assembly-plugin) to produce a zip file containing all the
jars, and deliver that with the releases of your webapp(s). Perhaps you
would tell the plugin about each of the war projects, and it would add
all of their dependencies into the jars zip. This assumes that you are
using Maven to build all the wars, so that Maven can look at the pom.xml
files for each to determine their dependencies.
You may also consider moving some or all of the jars out of the server
classpath and into the webapps. This may end up being easier to manage
since each webapp could depend on whichever version it needs, and not be
forced to use the version from the server classpath. Have you ever
experienced such issues with your current process? Maven has excellent
support for packaging dependent jars into the war's WEB-INF/lib dir.

I was reading a lot about how one of maven's best
features is the dependency handling: there is no need
for a directory of jar files. Everything is specified
in the dependency management and the repository has
the needed jars. Sounds good.
One of my coworkers raised however an issue the other
day which I couldn't answer. Any ideas welcome.
Here is the story: building with ant, our project had
one directory with all the jar files. On our
production server the contents of this dir was in the
tomcat/shared library (we have several apps running on
the servers and they share a lot of the dependencies).
Keeping it up to date with new jars was as easy as
synching with our ext_libs folder.
Now, we use maven. There is no more ext libs folder.
The dependencies however are not included in the wars
(scope: provided). They are already in the shared lib
of tomcat.
Question is: how are we supposed to generate the
contents of the tomcat ext libs folder at this point?
Looking up 100 dependencies from several pom files and
extracting the jars from the repository doesn't seem
so great. It seems as with the dependency managament
suddenly we lost the ease of keeping our production
server shared library up to date.
I wonder if there is some solution to this.
