Need your invaluable help....!

Hi Friends..,

i am using weblogic6.1, created a session bean and entity bean and
servlet to access these beans. it is working fine in weblogic.

now i want to change application server from weblogic to jboss. so, i
removed weblogic completely and downloaded
jboss-3.0.0.zip,jakarta-tomcat-4.0.4.exe and i installed it.

i compiled and executed my first servlet in tomcat, now i want to call
my ejbs from this servlet how to call ejbs from this servlet. what
are the xml files involved?. do we need to start... both jboss server
and tomcat server and if so how to build bridge between them..?

Please suggest me the go.

regards dinakar.
