AntFlow builds upon Apache Ant to provide a new approach to simplifying system automation that uses pipelines of hot folders chained together to perform a given task. Using XML, it associates an automated task such as data transfer, encryption, or XML processing with a directory on the local system. Whenever a file is copied or written into the hot folder, the associated task is executed and the file is moved to the next hot folder in the pipeline for further processing.
AntInstaller is a flexible front end for deploying applications using Ant build files as the engine. It provides a Swing GUI and a command line alternative for situations (such as server deployment) when X is not available. The installer is designed by creating an XML config file that describes the various pages of the installer and the input required from the user. The input is validated and can be dates, directories, options selected from a list, or other structured input. Once the properties are selected, AntInstaller runs and calls the selected targets. Primarily, it is designed for installing Java apps in a user-friendly way, but can be used for anything that requires structured input for Ant scripts.
Anteater is a testing framework designed around Ant, from the Apache Jakarta Project. It provides an easy way to write tests for checking the functionality of a Web application or of an XML Web service. It can test either HTTP requests or replies in various sophisticated ways. The ability to wait for incoming HTTP messages is unique to Anteater, which makes it especially useful when building tests for applications that use high level SOAP-based communication and asynchronous SOAP messages. Anteater provides XML and text logging support and the ability to render the logs into HTML reports.
Apache Jakarta Regexp is a 100% pure Java regular expression package. Expression syntax supports all of Perl5 syntax, with the exception of back reference substitution markers (several people have mentioned this lack, so please feel free to contribute a solution). It also supports a very limited subset of POSIX features. Performance and features are somewhat inferior to ORO, and the new JDK 1.4 (java.util.regex) package, but the package is especially small and features the ability to precompile expressions (without using object serialization) into byte arrays, thus avoiding the need to load the expression compiler.
The goal of the Apache Tomcat Project is to provide commercial-quality server solutions based on the Java Platform that are developed in an open and cooperative fashion. Tomcat 3.x is an implementation of the Java Servlet 2.2 and JavaServer Pages 1.1 Specifications. Tomcat 4.x is an implementation of the Java Servlet 2.3 and JavaServer Pages 1.2 Specifications, and is a re-implementation of the Tomcat servlet engine from the ground up. The current branch, Tomcat 5.x, is an implementation of the Java Servlet 2.4 and JavaServer Pages 2.0 specifications, with increased attention to scalability, reliability, and management functionality.
Velocity is a Java-based template engine. It permits anyone to use the simple yet powerful template language to reference objects defined in Java code. When Velocity is used for Web development, Web designers can work in parallel with Java programmers to develop Web sites according to the Model-View-Controller (MVC) model, meaning that Web page designers can focus solely on creating a site that looks good, and programmers can focus solely on writing top-notch code. Velocity separates Java code from the Web pages, making the web site more maintainable over the long run and providing a viable alternative to Java Server Pages (JSPs) or PHP. Velocity also provides template services for the Turbine Web application framework, making a template service that allows Web applications to be developed according to a true MVC model.
