Redeployment of ejb in weblogic7.0

[Harischandra Reddy C]

I want to know how to re deploy an ejb(bugged) which is modified with out effecting or deploying the complete .jar or .ear file.
I have 100 ejb's in a .jar or.ear file which is deployed in weblogic7.0 app server. I want to modify one of the ejb in the .jar or .ear file and I want to redeploy only that particular ejb.
Is there any smarter way to do this.
I will be greatful to you if you can give me the solution for this.
cheers
Hari
