Re: JSP support: works in bridged Equinox HTTP service, _not_ in bridged Felix; _exact_ same bundles
Hi Karl: Thank you for your helpful comment. I seem to have a working Equinox implementation atm, so I'll that be for now :) However, your statement about the pax bundles piqued my curiosity? Did you mean that you used: http://mvnrepository.com/artifact/org.ops4j.pax.web/pax-web-jsp/0.8.0 or something similar inside the Apache Felix _servlet bridge_??? It seems like you were able to get additional features besides a plain vanilla HTTP Service (at least JSP support), which would be quite interesting... I only ask because I know Pax Web itself does not have a servlet _bridge_ mode per my understanding (or at the very least does not have a servlet bridge mode that provides advantages over a traditional HTTP Service): http://lists.ops4j.org/pipermail/general/2010q4/004794.html Hi Misha, I think your assessment is correct about http services. Pax web won't bring you any advantages if you want to operate in a bridged mode. ... -Andreas (and penultimate comment here: http://forum.springsource.org/archive/index.php/t-55655.html) On Tue, Nov 9, 2010 at 2:12 PM, Karl Pauls karlpa...@gmail.com wrote: I don't know enough about your set-up (i.e., the bundles you use).
