Examples of net.sf.xbus.base.core.XException

net.sf.xbus.base.core.XException
All errors that occur while processing a request are handled by throwing a XException. Because nearly all methods possibly throw a XException, only a few points (eg. the receivers) have to catch and handle it.

      mQSYSobjPathname = new QSYSObjectPathName(filename);
