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?

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:
