Jtpl is a template engine for Java Servlet which allows you to store your HTML code apart from your Java code. A template engine is a software module which is used to generate HTML pages. The layout of a HTML page is defined within a template file, which can be designed by using a standard HTML editor. At run-time, the application program instructs the template engine to load the template, fill in variable values, repeat blocks and produce the final HTML page. There are other template engines (like Velocity, WebMacro or Struts) which are huge and use complex template syntaxes.

Expresso is the most popular, powerful, enterprise-strength J2EE architectural framework. Expresso extends Struts for developing database-driven web applications and builds on many other open source projects. Expresso is designed to shorten time-to-delivery of Web-based applications by providing a library of extensible Java Server components for providing services to web-based applications so the developer can concentrate on application logic. Expresso has capabilities for security, robust object-relational mapping, background job handling and scheduling, self-tests, logging integration, automated table manipulation, database connection pooling, email connectivity, event notification, error handling, caching, internationalization, XML automation, testing, registration objects, configuration management, workflow, automatic database maintenance and JSP tag library etc.

Java and JSP tool for designing and printing reports. It supports preview, printing and export to PDF , DHTML, XML, CSV and Text.

Other features are: headers, footers, groups, evaluation of expresions, integration of charts and barcodes, text mode reports for fast printing. The source code is available.

uitags is an open source JSP custom-tag library that makes developing friendly UI (user interface) effortless. It has a unique aim of helping developers create UIs that don't confuse end-users and instead let them work more efficiently.

ServletManager is an XML-based servlet controller package (in the model/view/controller paradigm) that allows a Web application programmer to declare the entire application's flow, application state rules, exception handling, authorization rules, model code (business logic) per state, and view code (Java server pages (JSPs) per state in an XML-based state table.

Brett McLaughlin continues his JSP best practices series with a look at the various techniques for adding time stamps to your JSP pages, as well as the ways that this simple modification can enhance the usability of your Web site.

The Common-Controls form a Java Presentation Framework based on Java Servlets, Java Serverpages (JSP) and Struts. The Presentation Framework contains the most common control elements like lists, trees, tabfolders, menus and forms, which are required for the development of J2EE applications with HTML frontends. The control elements distinguish themselves by the fact that they automatically save their own state across server roundtrips, so that the scrolling mechanism of a list, for example, or the explosion and folding of a tree structure do not have to be implemented independently. Rather, the state is managed by the control element itself, so that the developer can concentrate on the actual and important aspects of a Web application, such as the technical sequences or providing the data. The Framework takes over the presentation.
