PAX-WEB + PAX-CDI + WELD = Problem scavenging sessions' java.lang.IllegalStateException
by Alex Sviridov
Hi all
The question is about using Pax-Web (osgi servlet container) + Pax-Cdi + Weld.
There is a bug in pax-web https://ops4j1.jira.com/browse/PAXWEB-760 than can't
be fixed about 2.5 year. And it seems that it is linked with weld. So I post
my question here - maybe someone of weld developers can give any hints, ideas
etc that can help us. So, the situation.
Configuration: jetty 9.3.11.v20160721, weld 2.2.12.Final, pax-cdi 0.13.0-SNAPSHOT,
pax-swissbox 1.8.0 , pax-web 6.0.0-SNAPSHOT.We must have a war bundle with
servlet + cdi bean. In servlet we do
private void processRequest(HttpServletRequest request, HttpServletResponse response){
HttpSession session = request.getSession();
session.setMaxInactiveInterval(60);//Note, these are seconds.
....call some cdi bean method
}
The problem appears when we update war bundle on osgi when there is a live session.
So, timing is very important here. What we do by steps and time:
hr:min:sec
1) at 00:00:00 we start our war bundle
2) at 00:00:10 we make the first http request to our servlet with cdi bean call
3) at 00:00:30 we update our war bundle on osgi (Bundle.update)
4) at 00:00:40 we make the second http request to our servlet with cdi bean call
5) at 00:01:40 we get the following exception:

Interceptor & Interceptors
by Emily Jiang
Hi Martin,
In the updated Interceptor spec, it has the following statement:
"The Interceptor annotation is ignored on interceptor classes bound using
the Interceptors annotation."
I assume this already the case in Weld 2.x, CDI 1.2 implementation. Right?
Many thanks,
Emily
