1. Other Java Open Source Projects Quartz [Java Open Source Job Scheduling] Quartz is another open source project of the OpenSymphony organization in the field of job scheduling. It can be combined with J2EE and J2SE applications or used independently. Quartz can be used to create simple or tedious daily program tables for running ten, a hundred, or even tens of thousands of Jobs. Jobs can be made into standard Java components or EJBs. The latest version of Quartz is Quartz 1.5.0. Velocity is a Java based template engine. It allows anyone to simply use template language to reference objects defined by Java code. When Velocity is applied to web development, interface designers can synchronize with Java developers to develop a web site that follows the MVC architecture. That is to say, page designers can only focus on the display effect of the page, while Java developers focus on business logic coding. Velocity separates Java code from web pages, providing convenience for long-term maintenance of web sites and offering us an alternative solution beyond JSP and PHP. The capabilities of Velocity go far beyond the field of web site development. For example, it can generate SQL, PostScript, and XML from templates. It can also be used as an independent tool to generate source code and reports, or as an integrated component of other systems. Velocity can also provide template services for Turbine web development architecture. Velocity+Turbo provides a template service that allows a web application to be developed using a true MVC model. 【 VeloEclipse: An auxiliary development plugin for Velocity on the Eclipse platform 】 Roller Weblogger 【 Java Open Source Blog 】 This weblogging is designed quite ingeniously, and the source code is a great learning material. It supports the features that weblogging should have, such as commenting function, WYSIWYG HTML editing, TrackBack， Provide page templates, RSS Syndication, blog roll management, and offer an XML-RPC interface. XPlanner [Java Open Source Project Management] XPlanner is a web-based XP team planning and tracking tool. The unique development concepts of XP, such as iteration and user stories, are all provided by XPlanner with corresponding management tools. XPlanner supports the XP development process and solves the problems encountered when using XP ideas to develop projects. XPlanner features include: simple model planning, virtual note cards, iterations, tracking of user stories and work records, automatic iteration of unfinished stories, tracking of work time, generation of team efficiency, individual work hour reports, and support for SOAP interface. JOnAS [Java Open Source J2EE Server] JOnAS is an open-source J2EE implementation developed within the Object Web Consortium. Integrate Tomcat or Jetty as its web container to ensure compliance with Servlet 2.3 and JSP 1.2 specifications. The JOnAS server relies on or implements the following Java APIs: JCA, JDBC, JTA, JMS, JMX, JNDI, JAS, JavaMail. FreeMarker [Java Open Source Template Engine] FreeMarker allows Java Servlets to maintain the separation of graphic design from application logic by sealing HTML within the template. The template dynamically generates HTML using data provided by a servlet. Template languages are powerful and intuitive, with fast compilers that output speeds close to static HTML pages. 【 FreeMarker Eclipse Plugin and FreeMarker IDE: Auxiliary Development Tools on the Eclipse Platform 】 Lucene 【 Java Open Source
