PAJES is a presentation framework for Java Servlet API 2.2+ Web Applications.

Presentation Framework

PAJES provides a sophisticated set of HTML objects, and the ability to create a Java instance of a text HTML document, which may then be manipulated programmatically before being returned to the client browser. This allows complete separation of the HTML content from the code that manipulates and delivers the result to the client.

PAJES also automatically builds rules-based client-side (JavaScript) form validation routines, with no input from the page designer or the application developer.

A simple but powerful security mechanism, that can control whether any individual element on an HTML page is returned to a requesting browser, is also provided as part of PAJES.

Additional Web Application Development Features

In addition, PAJES provides some other facilities to ease web application development, including:

• Transparent handling of multi-part HTTP requests (file uploads).
• An extensible authentication framework where servlet container authentication is not used.
• Inbuilt database connection pooling, supporting all versions of JDBC drivers.
• A set of simple object-relational mapping classes.

(These features are only available in Servlet API 2.3+ compliant containers.)
