* Web Application
A web application is an application that is accessed over a network such as the Internet or an intranet. The term may also mean a computer software application that is hosted in a browser-controlled environment (e.g. a Java applet)[citation needed] or coded in a browser-supported language (such as JavaScript, combined with a browser-rendered markup language like HTML) and reliant on a common web browser to render the application executable.

* Web Container
In Java Platform, Enterprise Edition, a web container, also known as a Servlet container "implements the web component contract of the Java EE architecture".[1] This contract specifies a runtime environment for web components that includes security, concurrency, lifecycle management, transaction, deployment, and other services. A web container provides the same services as a JSP container as well as a federated view of the Java EE (formerly J2EE) platform APIs.

Examples of web containers are:

Tomcat for Java WSDP
Jetty
Sun Java System Application Server (is an Application Server, but includes a web container)
Sun Java System Web Server

java web application


* layout of a web application
These files are stored in a standard layout hierarchy of directories. Such a hiearchy is either in unpacked form or packed form.
  • Unpacked form
The files are seperately stored in the file system. This form is more useful while developing.
  • Packed form
After a web application has been developped, it will be packed (with jar). The files are then stored in a .war (Web Archive) file.
All servlets, classes, static files, and other resources belonging to a Web Application are organized under a directory hierarchy. The root of this directory is called document root.
  • The directory structure
The *.html, *.jsp, *.gif, *.jpg (that is the static web components) files go to the top level directory. These are the files that somehow can be retrieved by the client.
The Web Application Deployment Descriptor: is an XML file (named web.xml) that goes under /WEB-INF
/WEB-INF/classes: this directory contains the (compiled) java classes that are required for the application. 
If the classes are organized into packages, the package names are subdirectores under /classes.
/WEB-INF/lib: Contains .jar files that are required for the application. These classes include JSP tag libraries.
This tree must be found under <WebServerHome>/webapps
 <webapp-root>
   foo.gif
   bar.html
   /WEB-INFO
       web.xml
       /classes
            servlet1.class
            servlet2.class
        /lib
             foo.jar

flex application


* Adobe Flex
Adobe Flex is a software development kit (SDK) released by Adobe Systems for the development and deployment of cross-platform rich Internet applications based on the Adobe Flash platform. Flex applications can be written using Adobe Flash Builder or by using the freely available Flex compiler from Adobe.

* Flash application
the Java EE application server compiled MXML and ActionScript on-the-fly into Flash applications (binary SWF files).

* flex application
  • mxml + ac3
  • application type
    • web (runs in adobe flash player)
    • air (runs in adobe air)
