Automatic star-up of part of system after deploy: ServerSession problem

Question

Hello,
we have web application JSP, Struts, ADF, TopLink, JDeveloper 10.1.2.
TL descriptors are obtain from SESSIONS.XML.
What we like: Automatic starting part of system (scheduler) in thread after deploy on ( or restart) app server.
We tried put this activation in ActionServlet - and this works fine on both JDev-OC4J and OracleAS10g.
Problem 1: Two different ServerSession.
Activation code in ActionServlet (Scheduler) obtains ServerSession and works again. After first "browser-connection" ADF starts and obtains second ServerSession and works fine too. BUT - because two different ServerSessions, NO TopLink cache between Scheduler and "ADF" part exists and this is inacceptable.
So question 1: How to guarantee only one common ServerSession?
We tried synchronization from "ADF" part to "Scheduler" part after first "browser-connection" (send message to Scheduler with ADF ServerSession as parameter). This works fine on JDev OC4J only! On Oracle AS10g we get TopLink exceptions 3007(could not be converted to class) and after some modifications exceptions 7095 (no sessions.xml found) and 6007 (descriptor is missing).
I found no docs how to right solve this problem.
Please help me - how to write fine code to automatic start-up part of system (scheduler) in thread after deploy with only one common ServerSession?
Thank you very much for any hint.

Answer 1

hi,
1)Is this error occured at leat one secutity enable app installed?(Without application server works well?)
2)Is your app file base secutty enabled one(jazn-dat.xml) then what is the jazn-data.xml file size?
3)All ways keep a backup of newely created domain system-jazan-data.xml. Then you can replace the original one in case.
4)What is tha pllication? If it is an ADF app what is the version?
Nilum.
