When you launch merlin use the -info command line switch to get a list of the respective repository settings. This will show you the details of the system cache, the application cache, the remote repositories, etc. If that does not identify the problem could you post the -info trace to the list.
Cheers, Steve.

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
---- cause --------------------------------------------------------------------- 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

Artifact artifact = DefaultBuilder.createImplementationArtifact( bootstrap, getBaseDirectory(), getBaseDirectory(), MERLIN_PROPERTIES, IMPLEMENTATION_KEY);
final String repository = repo.toURL().toString(); final String[] hosts = { repository, "http://dpml.net";, "http://www.ibiblio.org/maven/"; };
