hi udo,
i dont see what the problem is. it seems like the ioc
container has problems to build the ServletApplicationInitializer
service. i just extended my own TapestryFilter with an empty
init method and everything works as expected.
if you look at the stacktrace you'll see that the
tapestryFilter tries to obtain the above mentioned
service from the registry.
ServletApplicationInitializer ai =
registry.getService("ServletApplicationInitializer"
,ServletApplicationInitializer.class);
may be you have a classloading problem here. where (package)
did you put your implementation of your filter? where
does the tapestry.app-package parameter point to?
i put my filter into my.package.structure.services whereas
web.xml points to my.package.structure
g,
kris

Hi Kris,
thanks for your help. The stack trace is quite long, I hope this part
conatins more clues:
