In order to get a grip on Merlin I am currently writing a little app
embedding it. I would like to have a local installation where merlin will
look for dependencies in a local cache first and will then fall back to the
usual suspects maven.repo.local, http://dpml.net/,
http://www.ibiblio.org/maven/:
app.home - bin
|
- lib
|
_ cache (1)
maven.repo.local (2)
http://dpml.net (3)
http://www.ibiblio.org/maven/ (4)
Following a fairly recent thread on this list I started out by adapting
org.apache.avalon.merlin.unit.AbstractMerlinTestCase and customizing
kernel.xml (see below). When running my main class, however, I get
----

Exception: java.io.FileNotFoundException
Message:
file:\C:\Data\OBergner\Maven\repository\avalon-framework\jars\avalon-framewo
rk-impl-4.1.5.jar (Die Syntax f�r den Dateinamen, Verzeichnisnamen oder die
Datentr�gerbezeichnung ist falsch)
in factory.create(criteria). I am very likely making a really stupid
mistake, but right now I am stuck and would be thankful if someone could
point me to a solution.
Ultimately, I would like to embed Merlin into a servlet. Any best practices
or, even better, code samples?
Thanks,
Olaf Bergner
