Hi,
When I do maven package, this gives me a bloated WAR with all the
dependencies which is 19MB in size.
For some reasons I need to deploy WAR onto my VPS time and again to test.
But deploying a 19MB war is time consuming, can I try to strip off the
dependency JARs in the WAR ?
Tried packaging a skinny war and referenced the the dependency jars with
shared.loader in catalina.properties, is this the right way to do it ?
Using maven2 and tomcat6.
Not to mention, I am very new to maven.

IMHO. This is the right way to do it.
We have a 60 POM project. About 10 build shared JARs that go into
Tomcat's lib folder. A few are intermediate aggregations used to build
larger composite POMs such as the Spring-Hibernate-MySQL-Tomcat POM
which actually depends of the 4 POMs that define the individual components.
These are referenced by the POMs that produce the WAR file as "provided".
Benefits:
1) Skinny WARs that only contain our code and resources.
2) Control over versions so that we do not get 5 version of common
libraries. The person defining the shared libraries has to do this once
for each new release cycle if we are changing technologies
(tomcat5=>tomcat6, MySQL5.0=>Mysql 5.1, new common-logging, etc.)
3) Developers do not have to worry about 3rd party libraries, there is a
list of libraries and version already available and known to work in our
set-up.
4) Module POMS have only 5 -7 dependencies to get everything that they
need and it is almost always the same for each module (WAR) POM. The
module POMs use a parent POM to get the Maven Plug-ins and repo
definitions, so they are really minimal even for Web Services which have
to produce both the WAR and the Client JAR.
Modules that are clients of Web Services will have the 5-7 common
dependencies as well as the dependencies on the client JARs for the
WebServices that it uses.
Very simple to make.
5) New versions are introduced in 1 place.
6) Deploy is fast since the WARs are tiny and once you have the shared
libraries in your cache, you never have to download them again within
the development of a single release of the whole application. (Our
shared libraries are immutable within a release.)
