Well, I've now come up with this block.xml:
<container name="hello">
<classloader>
<classpath>
<repository>
<resource id="avalon-framework:avalon-framework-impl"
version="4.1.5"/>
</repository>
<fileset
dir="/home_local/jpermar/midcvs/perseus/output/classes">
<include name="**/*.class"/>
</fileset>
</classpath>
</classloader>
<component name="hello"
class="edu.mit.ll.perseus.hello.HelloComponent"/>
</container>
But now I'm still getting the ClassNotFoundException:
------cause---------------------------------
Exception: java.lang.ClassNotFoundException
Message: edu.mit.ll.perseus.hello.HelloComponent
How can I turn on the merlin debug? I'm sure the directory in
the block.xml is correct, and I'm sure the class is there, but
merlin still isn't finding it (just want to see what the
classloader classpath is at run-time).
