Currently am working on core java. I mean am working with normal java with some JDBC. I would like to learn more tech's on java and i learnt servlets and JSP (haven't worked on any real time proj). For my work needs i have to learn EJB now. Is it right to start with EJB with this prior knowledge? To be very frank i really dont know what these spring,struts,hibernate ejb and many more means? Can anyone please help me in shaping my career with JAVA. Can you please give me the hierarchy in which i should move after having this little knowledge about servlets and jsp? What are the technologies i should read and in which hierarchy? Am really confused where to move.
