Spindle is a plugin for the Eclipse Platform that provides excellent IDE support for Web apps developed using the Tapestry framework. It includes wizards for creating applications and application components. Editors for applications, libraries, pages, components, and templates, all with popup help, syntax completion, and "as you type validation" are included. A project build process catches and marks almost every runtime Tapestry error before you deploy your application.
The par utility creates and manipulates PalmOS database (.pdb) and resource (.prc) files. Par is designed to be a Swiss army knife for managing these files. It's a command line tool, and not for the faint of heart, but it's very handy and replaces a bunch of little utilities that you might otherwise use.
ALF is a native logging framework for Java with the unique advantage of supporting automated method tracing. This platform-independent library allows developers to debug their applications quickly without adding any code. By simply adding an argument to the JVM, you will get immediate method tracing, which can be filtered by package or class and sent to the console or a file. You can also use the ALF logging library to integrate information, warning, error, or exception statements into the output.
The SMSj library allows you to send SMSes (GSM) from the Java platform. It gives you full control over the SMS including the UDH field so you can create and send EMS messages, Nokia ringtones, and images. It provides a pluggable transport layer that allows it be used with a range of different SMS servers.
NTXShape is a GIS data conversion tool that translates CARIS NTX interchange files into the ESRI shapefile format. It converts points, lines, polygons, text, spot heights, and soundings, preserving virtually all of the information found in the source data. It includes a command-line interface and a static library.
Xml Validation Interoperability Framework (xvif) is a proposal to embed pipe definitions in grammar based schema languages such as Relax NG (and probably W3C XML Schema). The current implementation is built on a partial implementation of Relax NG, supporting the features needed to provide a representative proof of concept. It is available both as Python source code and as an online demonstration. Although there is no endorsement of any kind by the DSDL ISO initiative (http://dsdl.org), one of the goals of this prototype is to gather feedback which may be used (or not) by "DSDL Part 1 - Interoperability Framework".
The NetBeans Filesystems Library provides The NetBeans Lookup Library as a standalone library that can be used independent of the NetBeans IDE or Platform. The lookup library provides a simple, powerful solution for two problems common to modular applications: Allowing new components to register objects that need to be visible to other elements of the system, and pseudo-multiple inheritance (allowing objects to change the functionality they offer dynamically by changing the contents of their lookup). It is available as a binary download, and JavaDoc is available. NetBeans uses Lookup internally to allow plugin modules to install new objects such as compilers that need to be found by the common infrastructure that supports them. However, the library can be useful in almost any situation in which loose coupling is desirable. It includes an AbstractLookup class and a number of other implementations of the Lookup interface that make it very easy to quickly get started.
Code Librarian is a Web frontend to CVS repositories, conceptually a merge of Bonsai and ViewCVS/cvsweb. It allows browsing recent commits to the repositories monitored by date as well as browsing the repository by path as a tree of files and their revisions. Colored unidiffs are shown in popup layers one click away from any browse view, and the interface tries to be both clean and powerful, without scaring away the novice user.
