Hello all, I just passed SCJP and am now moving on to advanced topics. I have tried 1 example of RMI, JNI, Beans(using Oracle's JDeveloper)and am reading Sun's tutorials on Servlets and JBeans. What is the most useful? Servlets? Any suggestions about what to concentrate on? I've read that most Java jobs now involve writing Servlets, and I'm going to build a portfolio, are there certain categories that would be good to include? Thanks!
J2EE is very hot right now. JSP, Servlets, JDBC, XML and EJB all all very good areas to work on. A good understanding of RMI could prove useful as well. David Sun Certified Programmer for the Java2 Platform
I would learn RMI very well, it is the building block of many j2ee ideas. You will do well to create your own rmi server/client and test them out. J2EE is quite a large animal and it will take some time to break all the components down that you want to learn. J. Carlson sun java2 certified programmer sun java2 certified developer
I believe many high-level concepts associated with J2EE (including JSPs and servlets) can be learned by reading about J2EE best practices and architectural recommendations posted as part of the "Blueprints" project at http://www.java.sun.com/j2ee/blueprints/ .
