NPE in Pax Web
Hi,
i have a problem with Karaf 2.2.4 and Eclipse RAP. I develop a web
application with Eclipse RAP 1.5 M4 [1], more precisely i use the RWT
widget toolkit and the RWT-OSGi [2] integration bundle to create a OSGi
based application.
Starting my application on Karaf 2.2.4, i see in the log file that the
rwt-osgi integration bundle registers a special servlet
"/servlet_context_finder" and also my servlet.
Later the rwt-osgi integration bundle unregisters the servlet
"/servlet_context_finder", which cause to stop the the ServletModel. A call
to my application results then in a NPE:

Hi Peter, JB
this should be fixe with the lastest 1.1.2 and 2.0 version of pax-web
(still snapshot)
might also be fixed with 1.0.8 (didn't check this yet :) ) which is
included in the next Karaf release 2.2.5

Re: NPE in Pax Web
Posted by Jean-Baptiste Onofré <jb...@nanthrax.net>.
Hi Peter,
thanks for the report. I will raise a Jira (at Karaf or Pax Web) and
work on the issue.
We are going to take a look but it will be at least for Karaf 2.2.6 as
2.2.5 is quite ready for a vote.
Regards
JB
