Java development for the web [closed]

Answer 1

Start with JSP backed by logic in Java classes. Or use servlets.

The advantage of using JSP and Servlets is that you gain knowledge of what all the frameworks do under the hood. And that understanding is crucial to figure out how to do X in that particular framework.

Furthermore, JSP is very easy. You can easily see what you're doing and very easily see it when you mess up the view with business logic.

And quite a lot of frameworks (Struts, Spring MVC) use JSP as their view technology. It's a natural first step in web development using Java.

Answer 2

something like grails ?

there is also the projects from spring

Answer 3

You could try Jboss Seam : http://www.seamframework.org/Documentation/GettingStarted

If you are using Eclipe as your IDE there is good integration via Jboss Tools or you can use the Seam-Gen tool that comes with Seam. This allows you to define a database table (or tables) and with a few easy commands, build an entire runnable web project from it. It's a nice way to get the ball rolling.

Answer 4

I learned Java in college back when it was in version 1.1.5. I recently started trying to program for the web, but it didn't make sense until I read Head First Servlets and JSP. There are way more things involved in web development with Java than I ever realized, and without this book, I would have quit and just used PHP.

Answer 5

This is a very open-ended question. The short answer is "yes" there are frameworks, libraries and standards to do everything from writing things at the HTTP request level up to content management systems in Java.

You can also use other languages (e.g. Python, Ruby, etc) on the JVM for that matter.

For some of the Java-only technologies, investigate JSP/Servlets, Struts, Struts2 (which is the updated version of Webwork), Spring MVC, Tapestry, web4j, Wicket.

There are other frameworks built on the JVM but use languages other than Java such as Grails.

To get started I would download Eclipse (latest version) and Tomcat. Create a new web application in Eclipse. There are guides that can get you started.

Start with learning how JSPs and Servlets work, these are a bit low level and aren't really a framework, but will let you get up and running quickly. From there investigate and choose your framework.

Spring MVC is pretty easy to get set up and going. I'm certain there are others.

Your basic java web technology is servlets. Servlets let you write Java code that responds to various HTTP events (doGet, doPost, doPut, etc). They're generally used for controllers in the MVC architecture. Link: http://java.sun.com/products/servlet/

JSP lets you write HTML with embedded Java instead of the other way around (in servlets). JSP has been extended via JSF to incorporate more recent architectural advances. This is in the same line as PHP and ASP. This is the view portion of the MVC architecture. Link: http://java.sun.com/developer/technicalArticles/GUI/JavaServerFaces/

A lot of more complex applications utilize Enterprise Java Beans (EJB) for session management, clustering, etc. This isn't a web technology, per se, but you see it go hand-in-hand when dealing with more complex webapps. Alternatives include frameworks such as Spring. EJB: http://docs.jboss.org/ejb3/app-server/tutorial/ Spring: http://www.springframework.org/

Also, you'll want to familiarize yourself with ORM technology (after servlets and JSP/JSF). The leading ORM framework is currently Hibernate. This lets you map SQL tables to java objects and interact with them accordingly. This is more advanced stuff so save it for when you're trying to get your head around EJB/Spring, etc. Link: http://www.hibernate.org/

edit: I forgot to define ORM. It stands for Object Relational Mapping/Mapper (whatever version of "Map" you feel like using :)
