Yes I know in OSGi it is quite another managed lifecycle, but so you can autostart stuff around the camel context to be preinitialized. - state listed as started=false (just do not invoke the stuff start() or as less as possible) > > > > > > > > -------- Original-Nachricht -------- > >> Datum: Mon, 29 Oct 2012 12:21:24 +0100 > >> Von: Claus Ibsen <claus.ib...@gmail.com> > >> An: users@camel.apache.org > >> Betreff: Re: Camel context autostartup > > > >> On Mon, Oct 29, 2012 at 11:36 AM, Benjamin Graf <benjamin.g...@gmx.net> > >> wrote: > >> > > >> > -------- Original-Nachricht -------- > >> >> Datum: Mon, 29 Oct 2012 10:30:36 +0100 > >> >> Von: Claus Ibsen <claus.ib...@gmail.com> > >> >> An: users@camel.apache.org > >> >> Betreff: Re: Camel context autostartup > >> > > >> >> On Mon, Oct 29, 2012 at 10:25 AM, Benjamin Graf > <benjamin.g...@gmx.net> > >> >> wrote: > >> >> > Hi Claus, > >> >> > > >> >> > thanks so far.
