Well, it should be mentioned, so that is an oversight I will fix, but it
is in the OSGi spec.

RE: ClassNotFoundException while exporting packages via org.osgi.framework.system.packages.extra
Posted by Ac...@emc.com.
Thanks Karl.
I added org.osgi.framework.bundle.parent=framework to the felix config, but that does not solve the problem. I still keep getting the java.lang.NoClassDefFoundError error.
The solution suggested by Richard worked.
Btw, I don't any documentation about using this property on Apache Felix site

Re: ClassNotFoundException while exporting packages via
org.osgi.framework.system.packages.extra
Posted by Nima Kaviani <ni...@gmail.com>.
Thanks Cliff for the hint on changing the log level. I was just too much
into finding the bug to think of reconsidering the log info! It turned out
that I was checking the dependencies on the wrong bundle. I did some
manipulations to the other bundle that was the source of the issue and the
issue is gone.
thanks again,
-Nima

Re: ClassNotFoundException while exporting packages via org.osgi.framework.system.packages.extra
Posted by "Clifford H. James" <cj...@proteuseng.com>.
Try turning the log level up a bit (-Dfelix.log.level=1) then
re-starting the framework. This should show the package wiring that is
occurring.
Do you have any bootDelegation settings on?

Re: ClassNotFoundException while exporting packages via
org.osgi.framework.system.packages.extra
Posted by Nima Kaviani <ni...@gmail.com>.
Hi guys,
it seems like I am having the same problem when trying to use the SWING
library.
I have got the following list of libraries exported using
system.packages.extra (I made the list shorter for brevity):
*org.osgi.framework.system.packages.extra=\
javax.sound.sampled.spi, \
javax.sql, \
javax.sql.rowset, \
javax.sql.rowset.serial, \
javax.sql.rowset.spi, \
javax.swing, \
javax.swing.border, \
javax.swing.colorchooser, \
javax.swing.event, \
javax.swing.filechooser, \
javax.swing.plaf, \
javax.swing.plaf.basic, \
javax.swing.plaf.metal, \
javax.swing.plaf.multi, \
javax.swing.plaf.synth, \
javax.swing.table, \
javax.swing.text, \
javax.swing.text.html, \
javax.swing.text.html.parser, \
javax.swing.text.rtf, \
javax.swing.tree, \
javax.swing.undo, \
.....
org.xml.sax.helpers*
and also have the parent bundle for the framework defined as Karl suggested:
*org.osgi.framework.bundle.parent=framework*
but when I try to run my program, which tries to use a JApplet, I get the
following error msg:
