Hi guys 
I have test JavaEE application deployed in SAP NW AS JAVA 7.4 via telnet
I enable http failover on_request in config tool (screen1)
In META-INF folder i put application-j2ee-engine.xml
<application-j2ee-engine xsi:noNamespaceSchemaLocation="application-j2ee-engine.xsd"><fail-over-enable mode="on_request" delta="on" xsi:type="fail-over-enableType_enable"/></application-j2ee-engine>
And add parameter icm/HTTP/J2EE/force_server_switch = 1 in J00 and SCS profiles icm/HTTP/J2EE/force_server_switch = 1
After that i restart SAP NW instance
My JavaEE app shows me time when session is created.
How i testing session failover:
1. undeploy test JavaEE app
2. deploy test JavaEE app
Refresh browser but session created time is new.
This meansthat the oldsessionis not saved((
I try monitor failover from SAP Managment Console in Sessions.
When undeploy session is gone . After that deploy, refresh browser and session is become .
Id Hash parameter the same before undeploy and after deploy.
How understand my session failover is working ? Stroed in file? Where this files is placed on filesystem?
