Could be: 1. Classloader issue - the MachineManager class loaded by the DefaultServiceManager isn't the same as the one loaded by the servlet. (I.e. they are loaded by different classloaders.)
2. The implementing class of the MachineManager interface doesn't implement MachineManager. Check that the servlet doesn't have its own copy of MachineManager. /LS > -----Original Message----- > From: Jaroslaw Palka [mailto:[EMAIL PROTECTED] > Sent: den 7 oktober 2003 16:43 > To: Avalon framework users > Subject: RE: ClassCastException in Jetty > > > The line which causes exception: > > MachineManager mngr = > (MachineManager)srvMng.lookup(MachineManager.ROLE); > > and here is output from program: > > class org.apache.avalon.framework.service.DefaultServiceManager > class org.apache.avalon.framework.logger.LogKitLogger > class $Proxy1 > -- > Open WebMail Project (http://openwebmail.org) > > > ---------- Original Message ----------- > From: "Leo Sutic" <[EMAIL PROTECTED]> > To: "'Avalon framework users'" <[EMAIL PROTECTED]> > Sent: Tue, 7 Oct 2003 16:02:19 +0200 > Subject: RE: ClassCastException in Jetty > > > Jaroslav, > > > > it's not obvious which line of your code causes the > > ClassCastException.
