Hi,
Your Bot should import the uk.co.talkingcode.ipojorc.api package. If
not, iPOJO can't access the Command interface when creating the array.
Just modify your import-packages of the Bot bundle to be:
sun.io;resolution:=optional,
javax.xml.parsers,
org.w3c.dom,
org.xml.sax,
org.xml.sax.ext,
org.xml.sax.helpers,
org.slf4j.*;resolution:=optional,
uk.co.talkingcode.ipojorc.api <-- Add this one
And then, it should works (quickly tried on my machine, and it
works :-)).
However, I was expecting a better error message from the Java when
this kind of error occurs, I will improve that, because the error is
definitely misleading.
Regards,
Clement

The problem seems to be that the Echo object is being inserted into an
array of IRCCommand, but (at least pre-weaving) Echo implements
IRCCommand so I don't expect that to be a problem. Source is here:
http://github.com/codders/ipojorc/blob/d8968531199600cda399a7aa3980a21b00ddc66a/bundles/echo/src/main/java/uk/co/talkingcode/ipojorc/commands/echo/Echo.java

metadata.xml for the two bundles ('core' being the consumer and 'echo'
being the provider) are here:

I'm basically trying to do this as my Hello World for iPOJO and
implement the program outlined here:
http://www.theserverside.com/tt/articles/article.tss?l=WhiteboardForOSGi
but with iPOJO.
Any help would be greatly appreciated.
