I am not exactly sure what you are seeing here with the following
exception trace, but the original constraint violation is most likely
due to the fact that you have multiple sources for the same package,
which are getting crossed wired. Unfortunately, it is not always easy to
give a good error report when it comes to a constraint violation.
I will keep your email message and try to investigate this a little more
to see what the precise issues are, but right now I am traveling so it
may take a little while.

Hi,
thanks for the hint but this gives another, maybe similar problem:
I first installed the compendium (started successfully this time),
then I tried to start the fileInstall Bundle, that gives me that

Does anyone tried that bundle successfully on felix before?
thx,Toni

Hello,
I had this problem with iPOJO in the previous version. It is a
modularity (i.e. import / export packages) problem. For me, it was
when my bundle imports and exports a package who is exported by the
compendium too. But my bundle does not specify the version number of
the imported and exported bundle.
Try the same scenario, but begin by installing the compendium. If it
works, check the imported and exported package from the fileInstall
bundle.

Hi,
I just tried to install the "fileinstall" bundle from aqute.
For that I need org.osgi.util.tracker.
The only bundle I found in the felix-trunk is osgi-compendium.
(found the necessary bundle with grep -R
"Export-Package.*org.osgi.util.tracker" * .. there must be a
better..???)
Trying to install that bundle, it results into a constraint
violation exception.
here is what I've done:
-> install http://www.aqute.biz/uploads/Code/aQute.fileinstall-1.0.jar
-> ps

Where is the constraint violation and how do I get that information ??
Kind regards,
