so now i think i have learned all basics and terminology for java. but what i don´t know is how to code and display a web page with Netbeans in Java.

the most tutorials contains lots of talks about different technologies "Java uses Java Beans, JSP and servlets" and so on. Where can i find short practical tutorials that actually teach me where to code what and then compile and where to put all the files (war, jar, ear..) in Glassfish to be able to see the output from a Web browser. Simples things that makes one understand all these different "layers" which are just classes using classes. Feels like i never get to know how i can put up a web server with Java cause I can´t find this kind of tutorials.

Would be great if someone could send some links to such practical stuff.

Thanks.

This is the first such document I found: http://www.java-tips.org/java-tutorials/tutorials/introduction-to-java-servlets-with-netbeans.html

I even found a small ebook on this (PDF!) http://www.comp.dit.ie/bduggan/Courses/projects/Getting%20Started%20with%20Tomcat%20&%20NetBeans.pdf

How do I code and display a web page with NetBeans in Java?

Let's go! Fire up NetBeans. I'm using NetBeans 6.7.1 with the Java EE stuff installed, and I've got a GlassFish installed and tied up, so I don't have to care about that stuff. Your setup might differ in the details.

Do a File->New Project, and pick "Java Web" from the categories. Select "Web Application" and hit Next. Enter a project name and tweak the location, if liked. Hit Next. The next page should have a server selection drop-down; as hinted above, mine has "GlassFIsh v2.1" selected. That's fine - as long as NetBeans can interact with a Java application server of some sort, this crash course will run okay.

Make a note of the "context path" - this will be based on the project name, and basically forms the base of the URL at which your application will reside. Hit Next. Ignore the next page, for now, which talks about various frameworks, and hit Finish.

Churn, churn. You should eventually see your web project created. It's a very simple application which contains a single JSP file, and that will be open in the main editor. It's got a bunch of HTML in it, and some JSP syntax.

Take a look at the project structure. You've got a "web pages" folder which contains a WEB-INF directory, and an index.jsp file. That's the same file you're looking at. WEB-INF is a standard directory which contains the metadata used to deploy your application, and also the compiled classes that power it.

The only thing you should need to do now, in order to get to the original objective, is to hit the big ol' Run button, or right-click on the project and select "Run" from the menu. NetBeans will compile, and then fire up your application server and deploy the application to it. Finally, your web browser should pop open a new tab with the classic "Hello, world" page in it.

At this point, what do you actually have? You've got an empty web project with a single JSP file in it. You could customise it, but that's maybe not very exciting. What you're really looking at is a basic framework in which you can apply your learning of JSP and of servlets as you get to grips with them.

How to proceed with said knowledge transfer? I recommend a decent book or two. The one I used to get going was "Beginning JSP, JSF and Tomcat Web Development: From Novice to Professional" (Zambon, Guilio; Apress; ISBN 1-59059-904-7), which has a decent beginner's guide to how JSP and servlets work together, and a handy reference guide for the former.

As soon as possible, you're going to want to migrate away from raw servlets and JSP to tying them together in a slightly more flexible way using one of the frameworks I skipped over earlier. I'm not going to tell you which one to learn; there are several pretty decent ones. Try Spring MVC, or Struts. Once again, I'd suggest getting a decent book.

I would start by taking a look at servlets and JSP. I found this book helpful when I read it: Head First Servlets and JSP

i crunch for thick books cause it contains so much other things:) better with short straight to the point tutorials. but i think i could give that one a try=)
The book is good and lots of fun. But most people who ask here want instant answers from the Internet ;)

Netbeans comes with many sample projects, create a few and browse the source code. A already working sample is always a good starting-point for your coding.

If you're also interested in using Eclipse, which makes it very simple to create and deploy web applications here's a nice tutorial - WTP Tutorials

Hi to start code and setting up web server with java follow the following procedure. First you need to install Apache-Tomcat or Jetty any web container or servlet container. And you have set the classpath of servlet-api.jar file. Next you will have to save your web-page code stuff in web-apps folder of tomcat.In web-apps folder there you have to create a web-inf folder in which web.xml file is stored.And after writing servlet and jsp programs the compiled class files are stored in classes folder of web-inf folder.JSP files are stored along with WEB-INF folder. You have to keep all the jar files in LIB folder of classes folder. The web container will take care of initalizing servlet, loading class using inti method.Using service method it will create two objects request and response.

The Java EE stack is quite a mouthful. I suggest you just look at writing a Web Application (WAR), and deploy it to Tomcat.

Unfortunately doing a full WAR-file deployment is rather tedious so you generally want some help from your IDE or the web container.

The easiest place to start is probably installing and starting Tomcat and then fiddle with the files in the file system. There is an example application.
