Hi Trupti, Check the ejb.jar file for proper name of the home,remote,bean classes.I they are ok while deploying you need to give the password while deploying the bean on WEBLOGIC 5.1. At command prompt you have to pass coomend as follows. (Before passing the command please run the weblogic/setenv file.Make sure that you have set environment variables in setenv file) java weblogic.deploy deploy weblogic anyname fullpathofyour deployable jar file(for eg:c:\weblogic\myserver\deployable jar file). anyname=anyname you can give for your deployment. weblogic=password on my m/c(check it in properties file of weblogic). I hope this will solve your problem. You can also write directly in properties file of weblogic installation.This looks something like as follows. weblogic.ejb.deploy = \ c:/weblogic/myserver/logindeploy.jar Thanx Mahesh
