Web Work - Design Goals and Overview

Design Goals and Overview

In a standard Java EE web application, the client will typically submit information to the server via a web form. The information is then either handed over to a Java Servlet which processes it, interacts with a database and produces an HTML-formatted response, or it is given to a JavaServer Pages (JSP) document which intermingles HTML and Java code to achieve the same result. Both approaches are often considered inadequate for large projects because they mix application logic with presentation and make maintenance difficult.

WebWork attempts to understand existing frameworks' limitations and works to eliminate them. It supports type conversion, continuations, and interceptors. WebWork also supports multiple-view technologies like JSP, velocity, and FreeMarker.

Ultimately, WebWork has been designed and implemented with a specific set of goals, that are very important for its users. They are as follows:

  1. Web Designer never has to touch Java code
  2. Create multiple "Web Skins" for an application
  3. Change Look and Feel
  4. Change Layout on a given Web Page
  5. Change Flow among Web Pages
  6. Move *existing* data elements from one page to another
  7. Integrate with various backend infrastructures
  8. Reuse components
  9. Perform internationalization (i18n) of a web application
  10. Keep the API small and to the point
  11. Ability to learn WebWork fast, by making all the fancier features optional
  12. Allow the developer to choose how to implement as much as possible, while providing default implementations that work well in most cases

Famous quotes containing the words design and/or goals:

    “You can make as good a design out of an American turkey as a Japanese out of his native stork.”
    —For the State of Illinois, U.S. public relief program (1935-1943)

    “Our ego ideal is precious to us because it repairs a loss of our earlier childhood, the loss of our image of self as perfect and whole, the loss of a major portion of our infantile, limitless, ain’t-I-wonderful narcissism which we had to give up in the face of compelling reality. Modified and reshaped into ethical goals and moral standards and a vision of what at our finest we might be, our dream of perfection lives on—our lost narcissism lives on—in our ego ideal.”
    —Judith Viorst (20th century)
