Depends, but I would suggest that you learn first about the meaning of
URL's, the http protocol, and make sure that you understand the meaning of
request headers and response headers, make sure you understand the GET and
POST methods.
Then start looking at the URL classes, URLConnection, URLEncoder and
URLDecoder, HttpURLConnecti on, URLStreamHandle r and URLStreamHandle rFactory
classes.
A very good book I can recommend is Java Network Programming (O'Reilly) from
Elliotte Rusty Harold.

If you go for Swing-less web application, go for Servlets, JSP and a MVC
framework like Struts.

Hope this gets you started,

Re: Java on Web

It all depends exactly what you mean by programming for the web? But i take
it from you post your interest is in java applets accessible over the web to
run in a browser? Not so different to regular swing apps, plus the html page
code to contain the app.

Then theres server side programming to create dynamic web pages- using jsp
and java servlets. For this you will also need an understanding of html of
course, and set youself up with a web server. Linux with the j2sdk, Apache
web server, Tomcat for the jsp pages, and MySQL for database access works
well for me...

Re: Java on Web

Thanks for the replies.

What I meant was how can I use the regular Java to create programs with the
browser as the interface?

I've done a lotta programming myself and do program for the web with PHP and
done some with C. But for example when I used C I had to rap the programs in
shell files as .cgi files so they're accessible by the web.

So how can you make a program that is written in Java (including all
necessary HTML outputs from the Java program itself) to be used from a
browser?


Thanks in advance.

Swing is not the right technology for this. What you are interested in
is servlets and JSPs. You will need a servlet container for them to run
in; try Tomcat from apache.org for a freely available one to get you
started. Use the tutorials on java.sun.com to get started on servlets
and JSPs. (Although the servlet API is pretty straightforward , if you
are a seasoned programmer you can probably get it going right away.)

The easiest way is probably to use JSP/Servlets and deploy them in a
JSP/Servlet container like Tomcat or Jetty.
