Hi,
With Jetty v9.3 (with PaxWeb 6.0.3), the GZipFilter is marked as obsolete.
As Jetty is really verbose about this deprecation, I am trying to upgrade
my application to remove all registration of the GZipFilter and use instead
a global GZipHandler.
However, I didn't succed to configure PaxWeb with this "HandlerWrapper" in
jetty.xml :
- The official way is to call "Server.insertHandler" which create a
chain of HandlerWrapper. However, PaxWeb seems to suppose that the first
handlerwrapper is his own "JettyServerHandlerCollection", and I have a lot
of exception ("java.lang.IllegalStateException: STARTED" on each
registratrion (cf [1]), and a ClassCastException when the bundle is stopped)
- If I call "getHandler().addHandler(..)", this doesn't work either :
the GZiphandler is either not call or throw a NPE as it doesn't have a
child handler
How can I use this Handler with PaxWeb ? Moreover, is there an equivalent
of the "jetty.xml" for undertow ?
Thanks !
