As a non IT person with a dream of building a scalable web based application for an educational idea, I am going through the Head First series and have completed HF Java, HF OOAD, and HF CSS/XHTML.

I am looking ahead to the EJB, Servlets & JSP, and Ajax books. I envisage that I will go to a local swap meet to buy some cheap hardware and set up my own server to play with.

Q1)Could somebody give me some advice on what kind of hardware I need to play with EJB JSP and AJAX? I currently have a standard box with an ADSL connection. The server will not need to go �live�.

Some supplementary question if I may

Q2)what server side software do I need? Can somebody point to a link to explain? I am not sure how J2EE, EJB, Tomcat and JBoss relate to each other.

Q3)I understand that the EJB Head First book uses J2EE which is now out of date with Java EE 5. Does this make the book redundant, or will it still be worthwhile?


Thanks

Marten

Hi Marten ,

Servlet and jsp are web components .ejb is a business component .to write applications you require appropriate api's such as servlet-api.jar ..

If you use weblogic all comes under weblogic.jar which comes under weblogic server.just set classpath to that jar and compile your applications.

and then deploy it in the server. hardly you require to install server.

You dont need a any special hardware ...your laptop or PC can be used for your application .

For JSP-Servlets you need a servlet container - Apache Tomcat is the best and freely available.
http://tomcat.apache.org/
Follow the installation instructions .

For EJB you will need a EJB container . You can use JBOSS or any other open source server.

The book is still worthwhile . But you need to read the new features from the specs available on Sun website
