Hi Dan,
I believe this is slightly different - I am trying to set a field for a complex
type ( the field is of type 'java.lang.Class'). The complex type itself gets
instantiated fine but the issue comes when attempting to setup the field. Brett
drilled down the issue to be missing convertor impl (String -> Class) in plexus
container, and now it seems to a related to ClassLoader.
But even in case of what you are referring to you should be able to specify an
'implementation' attribute for your complex type and specify the implementing
class from a different package.
Cheers,
Rahul

I think i ran to this before. The configuraiton object must be in the same
packge of your mojo.
Not sure if this helps thou.

Hi ,
I did relevant updates to m2 sources on local and updated m2 install for
plexus-container-default verison 1.0-alpha-10-SNAPSHOT. But still running
into a
ClassNotFound error. Looks like its coming from Classworld libs.
I have posted the stacktrace at:
http://www.rafb.net/paste/results/tke4hi45.html
Could this be a Realm related issue with Classworlds (sorry, not very
well-versed with Classworlds). I am sure that implementation class I am
specifying is available via dependencies in project's pom.xml. Am I
missing
something here or could this be a bug?
Cheers for any help!
