Can anybody explain what DTO is..
What i know about DTO is that it is a wrapper which takes data from DAO to View handlers.
Are they same as Value Objects ?
Kindly give some url where i can find information about DTO in detail

Can we use it with EJB's only.. or can we use it with JSP's also..
if yes please tell how ..

Not the same, but often implemented that way. See http://test.javaranch.com/wiki/view?DataTransferObject
