Please read the documentation at
http://jakarta.apache.org/avalon/developing.index.html
This covers in detail the structure of the "cocoon.xconf" file, which
BTW, can specify sitemap components. It also covers the correct idioms
for Component naming and ROLE referencing. Cocoon has now adopted these
idioms, and the Roles.java file is not necessary. The "cocoon.xconf"
can accept an attribute at the root level called "user-roles" to allow
you to refer to an external roles document.
<cocoon version="2.0" user-roles="additional.roles"/>
You don't _have_ to use the roles document either--the configuration
file has a standard markup that is on the verbose side.
The above link will help straighten out all of those issues.

This has been addressed to some degree. Have you tried this recently?
I know Dims put some work into it.

The Avalon team is very aware of these issues, and are trying to
deal with issues of trust and versioning for Server ARchives (SAR
files) and Block ARchives (BAR files). When we get these in order,
we will also address simple Components. You may integrate your own
Components into Cocoon's space though. Just check out the document
I referenced above. You will find that Avalon is pretty flexible.
