Re: Need help regarding deployment of an ear file using Weblogic

First try to find out which module of your application is creating a problem.

e.g
step1--deploy your ejb seperately

step2--deploy ur war file

if it gets deployed successfully then aftre undeploying both again deploy the entire ear file.

also i think weblogic 7 has a tool to assemble the application.Try opening the application from there.u should be able to trace it if there is some problem in the descriptor before deployment

all the best
