After the scheduled agent has run, I can only find the feature jar of the extlib in the workspace/feature directory.
I cannot find the fragments
com.ibm.xsp.extlib.connections
com.ibm.xsp.extlib.domino
com.ibm.xsp.extlib.mobile
com.ibm.xsp.extlib.oneui
com.ibm.xsp.extlib.sametime
Looks like they do not get deployed.
