| <section name="What is Turbine?"> |
| |
| <p> |
| Turbine is a servlet based framework that allows experienced Java |
| developers to quickly build secure web applications. Parts of |
| Turbine can also be used independently of the web portion of Turbine |
| as well. In other words, we strive to make portions of Turbine |
| easily available for use in other applications. |
| </p> |
| |
| <p> |
| <strong>A web based application is an application where users use |
| their favorite web browser in order to access secure business |
| logic.</strong> |
| </p> |
| |
| <p> |
| A couple example web applications that can benefit from using this |
| framework include e-commerce shopping cart |
| systems, Yahoo style link conservatories and project / <a |
| href="http://scarab.tigris.org/">bug/issue</a> tracking systems as |
| well as cool XML integration applications like <a |
| href="http://portals.apache.org/jetspeed-1/">Jetspeed</a>. |
| </p> |
| |
| <p> |
| <strong>A platform for building applications, not just running |
| them.</strong> |
| </p> |
| |
| <p> |
| Many commercial (and non-commercial!) software companies will |
| attempt to sell you an "Application Server", but what few people |
| realize is that it is only half of the battle to creating a web |
| application. There is often quite a lot of code that your engineers |
| end up re-inventing the wheel with or grabbing various packages from |
| all over the net with various licenses that you may or may not agree |
| to. |
| </p> |
| |
| <p> |
| The point of Turbine is to collect that code into one location and |
| make it easy to create re-usable components (such as |
| ParameterParsing, Database Connection Pools, Job Scheduling, |
| GlobalCaches, integration with other tools such as Torque, Velocity, |
| etc...) all under a <a href="/common/license.html">license</a> |
| (Apache) that allows you to create useful websites for your |
| customers without worrying about viral code. Turbine is not the end |
| all answer, but it sure is a nice way to make your development life |
| easier. |
| </p> |
| |
| <p> |
| This framework has an intended audience that is directed at web |
| engineers, not necessarily the web designers. By using this |
| framework, it is possible for the web engineers to build intuitive |
| high level systems for the web designers to use, but the low level |
| framework is strictly for web engineers. Turbine is not a web |
| application server. It is a tool for building web applications. Your |
| <a href="http://tomcat.apache.org/">servlet engine</a> is your |
| application server and the application that you develop using this |
| framework is your web application. |
| </p> |
| |
| <p> |
| <strong>Integration with Velocity is well |
| defined and makes doing applications using these tools painless for |
| both the developers and the web designers!</strong> |
| </p> |
| |
| <p> |
| Turbine can be integrated with existing <a |
| href="http://velocity.apache.org/engine/">Velocity</a>, <a |
| href="http://java.sun.com/products/jsp/">Java Server Pages (JSP)</a> |
| and <a href="http://cocoon.apache.org/">Cocoon</a> technologies by |
| specially creating Screens that use Services to parse templates. |
| Screens can also be created to read files from other websites as |
| well as off disk. This makes it easy to have designers simply put |
| the body of a page on disk and Turbine can serve these files when |
| requested. All of this is described in more detail in the |
| documentation section below. |
| </p> |
| |
| <p> |
| The reason why Turbine works so well is because it applies object oriented |
| principles to the entire process of building a complex secure web application. |
| We try to follow the |
| <a href="http://www.javaworld.com/javaworld/jw-12-1999/jw-12-ssj-jspmvc.html">Model |
| 2 methodology</a> yet expand on it to encompass "View" technologies other |
| than just JSP as well as more mature methodologies such as |
| <a href="./howto/action-event-howto.html">Action |
| Event</a> handling. Turbine is considered as Model 2 <strong>+ 1</strong>. :-) Please |
| see the <a href="model2+1.html">discussion</a> of Model 2+1 for more information. |
| </p> |
| |
| <p> |
| This all sounds like a bunch of marketing talk, but in reality, |
| Turbine has been developed by developers for developers. We are not |
| trying to sell you something that does not really work, instead we |
| are trying to solve (or do something about) the problems that our |
| fellow developers keep having over and over again. Come be a part of |
| the revolution! |

| |
| <p> |
| We really need and appreciate any contributions you can give. This |
| includes documentation help, source code and feedback. Discussion |
| about changes should come in the form of source code and/or very |
| detailed and well thought out constructive feedback. The <a |
| href="how-to-help.html">How To Help</a> document has details and hints |
| how to get engaged with Turbine Development. We also have a <a |
| href="todo.html">To Do</a> document that describes work to do with |
| the current Turbine code. |
