Hi Ulf Dittmer,
I have put down the sapjco.jar file under the lib folder of JBoss server.
And removed it from my application. However for build path i have to export it from some another location.
but now my application .ear file doesn't have any sapjco.jar and i checked by scheduling some dummy method and by redeploying the application few times.
It is not giving the previous exception now.
I hope it also works in the real environment.
I need to workout around timer and timertask a little more so as to make their working fine(in real environment with live tasks).
BOTH OF MY PROBLEMS HAVE BEEN SOLVED FOR NOW............
HOPE SO ...........
THANK YOU VERY MUCH FOR YOUR HELP AND IMMEDIATE REPLIES HATS OFF TO YOU
