jscl-meditor aims to provide a free and open source Java symbolic computing library with a mathematical editor front-end. There are several computer algebra systems available on the market, most of them developed in other languages, mainly C/C++ and Lisp.
But the benefits of using java in symbolic computation are great. Aside from being widely used and to comply with various standards, this language has two features of concern : readability and portability.

The symbolic capabilities are currently:
- polynomial system solving
- vectors and matrices
- factorization
- derivatives
- integrals (rational functions)
- boolean algebra
- simplification
- geometric algebra
- java code generation
- graphical rendering of math expressions

JFW offers to the programmers a multi layer architecture and MVC, based on Struts and utilities classes.
In short, JFW offers features like connection pools, logging management and more utilities classes that not offered by Struts.
The goal is not to create a new MVC framework but to offer a real-world implementation and use of an existing framework already used by many programmers, simplifying the use of that framework and maximizing the productivity.
Moreover, JFW offers all the utility classes used in most of the web applications, like connection pools, gateways that allow to execute sql instructions and stored procedures.
Also, Log4J based logging is provided, but with some extensions that permit to be controlled from remote, management of the authentication, authorization and profiling of the customer, a simple scheduler and many other utility classes.
Sure, some of the previous functionalities are also offered by other libraries or frameworks and in some cases they offer more functionalities than JFW.
But these libraries are created by various development groups and this demands the knowledge of different interfaces for using the offered functionalities, with different types of configurations.
Since a framework or library is useless without an adequate documentation, a considerable part of our job is dedicated to create useful javadocs and practical examples, in order to make JFW and webapps ready to the use.
