here the mistake u did is while creating war ur using jar-cv0f x.war urjsp meta-inf
instead of meta-inf u have to specify web-inf,and in this web-inf ur web.xml should be placed.
when ur intrested to deploy ur application in archive format why dont u try to make .ear with ur jar and war files.if u r able to make .ear waith jar and war u can easily deploy ur .ear..
any way here is an excellent link from weblogic about ur problem: http://edocs.bea.com/wls/docs61/programming/packaging.html
goahead with this still u have any problem write me ur problems..
or else send me ur mail id...so that i can contact u..
