Setting classloader for extra dependencies

[Alexander Brill]

Hi,

With the <dependencies> tag you can add extra dependencies to the container execution classpath. As I am running Tomcat I'd rather have these extra dependencies get copied into either my common/lib or server/lib directory.

I figured this isn't implemented yet, however I have a bit of time to look into it. But... What would be the best approach to get this as generic as possible from the configuration perspective? One possible solution that comes to mind is:

<dependencies>
  <dependency>
    <groupId>foo</groupId>
    <artifactId>bar</artifactId>
    <output>jvm | common | server</output>
  </dependency>
</dependencies>

Comments?

there is the concept of a "sharedclasspath" option that does this, it
currenly only works with ant right now (it shouldn't be too much of a
problem to get the maven extension working with it). And it isn't
documented. It works similar to the extraclasspath option
(http://cargo.codehaus.org/Container+Classpath).

How do I use this with ant, and better yet - which classes should I look at? :)

see the bottom of http://cargo.codehaus.org/Container+Classpath is gives
an example of how to extraclasspath, just substitute shared for extra.

its spread out among a bunch of classes. For Tomcat look at
AbstractCatalinaStandaloneLocalConfiguration's DoConfigure method to see
how its done in Tomcat.
