EJB : ANT WEBLOGIC 8

Question

Hi Friends,
I am new to EJB, ANT and Weblogic - so need a help from you.
I want to run a simple session bean on weblogic 8 but want to deploy using ant along with my other servlets and jsp's, please point to simple tutorials.
I have some basic questions.
1. So far I am deploying my application as .ear file just by typing "ant copyEar" and happy to see my changes, so question is can I deploy my EJBS as part of this ".ear" file ?
2. If so can I go and see my deployed EJB's thro' weblogic console just like my application ?
3. If I can deploy the EJB as part of ".ear" (which I believe) please send me the build.xml contents (Now my build.xml compiles all java, jsp files and deployes automatically) - so what I try to ask is do I need to change the build.xml to accomodate EJB's ??
4. Please if possible give a simple example which I can try myself.
Thanks,
~Deepa

Thanks seeteshh,
I did try one, but not succeeded.
Can any one tell me what I need to add to my build.xml to include EJB as part of my application. ".ear file"
1. My "build.xml" looks like this
<!-- Ant build script -->

2. My java files are under "classes" directories (from ant base directory)
3. ejb-jar.xml & weblogic-ejb-jar.xml are under "config\classes\META-INF" directory
4. With above build.xml ant runs SUCCESSFULLY but when I try to run the EJB Client get the following error
:::::::::::::: Error :::::::::::::::::
javax.naming.NameNotFoundException: Unable to resolve 'stateless-session-demo' Resolved [Root exception is javax.naming.NameNotFoundException: Unable to resolve 'stateless-session-demo' Resolved ]; remaining name 'stateless-session-demo' at weblogic.rjvm.BasicOutboundRequest.sendReceive(BasicOutboundRequest.j

5. Thank you so much for your time.
