That's a smart trick they're doing. I'm not whether it is a good idea
for Wicket however. I think we're not doing that bad, having just 3
needed dependencies (ognl, concurrent and commons-logging... can someone
confirm we don't need dom4j?). The advantage of not packaging the jars
is that it allows users to choose which actual version of the
distribution they want to use (e.g. ognl-2.6.5 instead of 2.6.7) and
that it saves us the task of being up-to-date with the latest versions
of our dependencies.
Thanks for providing the idea, it looks usefull for my paid projects...

I was noticing that Wicket seems to have a lot of dependencies. I think
that is great (because you aren't reinventing the wheel), but it can
easily cause great frustration if Wicket is used with other frameworks
that require a different version of one or more of those dependencies.
I noticed that Groovy is currently using the below tool (called JarJar)
so Groovy can be easily dropped into a project without potential for
library version collisions. I haven't used it, but it appears to
repackage dependent libraries into the main Jar file with different
package names. The main code automatically references the new dependent
package names.

The benefits I see:
1) Just one Jar for people to drop into their webapp (I'm always for
making things feel easier and cleaner for new uers :-)
2) No strange issues related to dependency conflicts. (Another
ease-of-use/lack-of-frustration feature)
3) Fewer posts asking why something doesn't work when it's just a
library version issue.
My 2 cents :-)
