Re: @SessionScoped and @ConversionScoped
Hi
I'm putting together a mail to our technical contact at IBM about this.
Does OWB have some pages describing its implementation of the SPI for fail
over?
Regards
Lars-Fredrik

@Mark
Yes, looks good.... nice of them to share some information.. Should have

Re: @SessionScoped and @ConversionScoped
Posted by Lars-Fredrik Smedberg <it...@gmail.com>.
Hi
@Mark
We got some answers back from IBM regarding OWB and configuration of
WebSphere 8.5.5.1.... here are some of the key points of their answer
- WebSphere CDI implementation is based on OpenWebBeans (which we already
knew)
- WebSphere sets both of the following properties to true by default:
org.apache.webbeans.web.failover.issupportfailover=true
org.apache.webbeans.web.failover.issupportpassivation=true
They suggest not changing that unless there are a good reason to do
so...
- The CDI implementation registers a HttpSessionActivationListener. On a
call to sessionWillPassivate it stores the failoverbag (the session and
conversation contexts) as an attribute in the session (if
org.apache.webbeans.web.failover.issupportpassivation=true)
- The CDI implementation registers a ServletRequestListener. On a call to
requestDestroyed it stores the failoverbag as an attribute into the session
(if org.apache.webbeans.web.failover.issupportfailover=true)
In summary it should work out of the box with no additional configuration.

Fredrik
