Hi,
I found this link in one of Scott's reply to related query in the mailing list.
http://wiki.apache.org/portals/Jetspeed2/PrefsClassloaderIssuesAndSdk14
However, I am using j2sdk1.4.2_04 and the error that I am getting is
NullPointerException, not classnotfound . So I rebuild jetspeed2 with
a debug statement to print the stack trace wherever the
org.apache.jetspeed.prefs.PreferencesException is thrown in the
PreferencesFactoryImpl class . I got the following stack trace. Can
someone give me some pointers on why I am getting this exception?
java.lang.NullPointerException
