The Web Application Component Toolkit is a framework for creating web applications. WACT facilitates a modular approach where individual, independent or reusable components may be integrated into a larger web application. WACT assists in implementing the Model View Controller pattern and the related Domain Model, Template View, Front Controller and Application Controller patterns.

The WACT framework is developed with the philosophy of continuous refactoring and Unit Testing. WACT encourages these activities in applications based on the framework. WACT uses Simple Test as a unit testing framework.

WACT emphasizes writing secure web applications. See Web Application Security for more information.

Symfony is a web application framework for PHP5 projects.

It aims to speed up the creation and maintenance of web applications, and to replace the repetitive coding tasks by power, control and pleasure.

The very small number of prerequisites make symfony easy to install on any configuration; you just need Unix or Windows with a web server and PHP 5 installed. It is compatible with almost every database system. In addition, it has a very small overhead, so the benefits of the framework don’t come at the cost of an increase of hosting costs.

Php On Trax (formerly Php On Rails) is a web-application and persistance framework that is based on Ruby on Rails and includes everything needed to create database-backed web-applications according to the Model-View-Control pattern of separation. This pattern splits the view (also called the presentation) into “dumb” templates that are primarily responsible for inserting pre-build data in between HTML tags. The model contains the “smart” domain objects (such as Account, Product, Person, Post) that holds all the business logic and knows how to persist themselves to a database. The controller handles the incoming requests (such as Save New Account, Update Product, Show Post) by manipulating the model and directing data to the view.

In Trax, the model is handled by what’s called a object-relational mapping layer entitled Active Record. This layer allows you to present the data from database rows as objects and embellish these data objects with business logic methods.

Fusebox is a framework for building web applications. It is meant to make your applications easier to create and maintain. It also makes team development easier. It does this by helping you structure your application and break things down into discreet pieces. Fusebox consists of a set of core files which handle much of the “plumbing” necessary when creating a web application.
A Fusebox application is made up of Circuits. A Circuit corresponds to a directory in your application. Within each circuit are one or more Fuseactions.
A Fuseaction is a request handler. And finally, a Fuseaction does its work by executing one or more Fuses. Fuses are individual PHP templates such as display or query files that are specific to the application you’re developing.
The framework uses XML configuration files to define the application settings as well as declaring what each Circuit does and how Fuseactions within each Circuit execute. There is a core set of XML grammar that is used to create these files.
The framework is fully extensible via Plugins, which allow you to extend the core functionality without having to modify the core files. It also supports Custom Lexicons, which allow you to extend the XML grammar with your own tags. As a result, Fusebox is very flexible and can support a wide range of development needs.
Fusebox does not force the Model-View-Controller (MVC) pattern or Object-Oriented Programming (OOP) on the developer. However, either or both of these development approaches can be used with Fusebox with ease.

Google App Engine was released yesterday for Java. It provides the ability to deploy Java based web applications onto the App Engine, and provides a data store service (with JPA and JDO on top of it), memcached, and others. So, what I decided to do is try and get Compass integrated with Google App Engine to allow for easy full text search of Google App Engine apps (yea, the irony). Basically, it took me a couple of hours, and we have something ready to use.

What are the steps needed?

• Make your domain model searchable.
• Create a Compass instance. Configure it to store the index using GAE data store (there is also support for native Lucene applications). Configure it not to use threads.
• Create a Compass Gps, have it automatically mirror changes done using the JDO/JPA API to the search engine. Call index operation to completely reindex your application.

Thats it. Pretty simple no? Especially since these are the steps you use to enable any Java application with full text search using Compass .
