I'm feeling overwhelmed - JSP, EJB, Struts, Swing, Hibernate, Tomcat, JBoss!!! I don't think my university (La Trobe Uni, Australia) lecturers know much about these! I have completed 6 units of a Grad Dip in IT, including introductory Java programming, and Data Structures using Java. This coming semester I will finish with OO Programming using Java, plus Web Engineering (CGI, Perl ...). I am doing a career change from secondary maths and IT teaching, and need to get a job sooner rather than later (wife and 3 young children to support). I think I should teach myself J2EE. Yesterday I borrowed "Java for the Web with Servlets,JSP, and EJB" and thought, "Beaut, I'll just work my way through this and I'll have a good basic understanding of J2EE". Unfortunately, even though I have got Tomcat 4.1 working (I decided to use that since the book is 2002), for some unknown reason, when I try to call my servlet from Firefox (localhost:8080 etc) I get an error message: "The requested resource (/myApp/servlet/Testing) is not available".

The book is 4 years old so maybe I should try something more up to date anyway, though any advice on what may be going wrong would be welcome - the servlet code can be seen on: www.samspublishing.com/articles/article.asp?p=26920&seqNum=4

I like the look of the Head First series - do you think someone at my level should tackle Servlets & JSP and then EJB? Any general advice on getting started in an IT career would also be welcome.

Learn the essential specifications - JSP , Servlet , EJB , JDBC. Learning DHTML, CSS and Javascript occurs automatically when you code sample programs using the above technologies. Lay your hands on Struts too as it is used in most of the frameworks.

Then you may learn other technologies depending upon the requirements of your project.

Try going through this tutorial instead. You will be using Eclipse, Java 5, and Tomcat 5.
