Re: [equinox-dev] Problems with JUnit and CNFE

[Thomas Watson <tjwatson@xxxxxxxxxx>]

I don't see anything obviously wrong
with your manifest files.  What other bundles do you have installed?
 Is it possible you got wired to the wrong exporter of junit?  Try
running with -console and then run the "bundle" command against
your bundle to see what packages it got wired to.  If you run the
"ss" command you will get a short summary of all the bundles
you have installed.

Subject	[equinox-dev] Problems with JUnit and CNFE

Hello!

I'm trying to use a JUnit plugin I found in the KF bundle repository to
run
JUnit tests from within the osgi framework. I am able to install the plugin
and get it in an ACTIVE state from within Eclipse.

However, no matter what I try, I keep getting CNFE for junit.framework
classes from within my consuming bundle.


Is there anything "special" I need to consider in the Eclipse
environment? I
can't seem to figure out why I can't import the classes, though I've tried
many approaches.


Thanks for any hints!
