EasyStruts provide advanced support for developing Struts web applications with Eclipse . keywords: MVC, Struts, Eclipse, Java
Green, an Eclipse plugin, is an advanced yet simple UML class-diagram tool, developed primarily for student use. It does live round-tripping, so it's easy to move between diagram and code views. It's extensible: users can define their own relations
Syntax tree editor for rapid annotation of existing text
Linguistic Tree Constructor (LTC) is a tool for drawing lingusitic syntax trees of already-existing text. It is a syntax editor, not a text editor, so the text has to exist already. It is best suited for large-scale, rapid creation of hand-annotated treebanks. The user can define their own node categories, and can label each node with labels, also definable by the user. LTC supports "generic", X-Bar and RRG trees. Supports interlinear texts in SIL SFM format.
Write, check, index and diagram Z specifications in Microsoft Word.
Tools to allow Z specifications to be written in Microsoft Word. Includes a unicode font for Z symbols. Provides: WYSIWYG editing fully integrated into Word; Typechecking using fuzz (for Spivey Z) or CZT (for ISO standard Z); Indexing and cross-referencing; Diagrams of specification structure; Conversion from Spivey to Standard Z- also available as a stand-alone program and Java class for non-windows users. See project website for details.
PlantUml Dependency allows to parse / reverse engineering source files (only Java is supported by now) to generate a PlantUml description, allowing to draw the UML class diagram associated to the source code.
Free software for generating understandable and accurate fuzzy systems
GUAJE stands for Generating Understandable and Accurate fuzzy models in a Java Environment. Thus, it is a free software tool (licensed under GPL-v3) with the aim of supporting the design of interpretable and accurate fuzzy systems by means of combining several preexisting open source tools, taking profit from the main advantages of all of them. It is a user-friendly portable tool designed and developed in order to make easier knowledge extraction and representation for fuzzy systems, paying special attention to interpretability issues. GUAJE lets the user define expert variables and rules, but also provide supervised and fully automatic learning capabilities. Both types of knowledge, expert and induced, are integrated under the expert supervision, ensuring interpretability, simplicity and consistency of the knowledge base along the whole process. Notice that, GUAJE is is an upgraded version of the free software called KBCT (Knowledge Base Configuration Tool).
The bflow* Toolbox is an open source tool kit for business process management. The objective of bflow* is to explore new ways and scenarios for the development and use of modelling tools.
Pretty Damn Quick (PDQ) analytically solves queueing network models of computer and manufacturing systems, data networks, etc., written in conventional programming languages. Generic or customized reports of predicted performance measures are output.
Domain-Driven Design sample application implementation
A complete, fast, previously commercial, JDO 1.0.1 implementation for databases, opened by Versant in 2005 and then abandoned in early 2006. The design-time code is already in Eclipse Dali. This project is the original source drop, including the runtime.
Make a tag cloud from text in your files
The Tag Cloud Maker application allows the specification of a source folder containing files that are parsed and the words counted and displayed in an HTML word tag cloud.
A modeling tool for software engineers (OO)
Object Graph Visualizer is a tool primarily meant to be used in CS courses to help new students understand the Object Oriented paradigm and patterns. Classes and objects - that can be part of a software project - are visualised in 3D: The classes stay In the xz-plane in form of an UML class diagram. Directly above in the y-axis objects can be instantiated as an object diagram. Classes can be connected with all sorts of relations (Associations, Compositions, Generalization, etc.), objects with object relations. Following additional functionality is provided: Attributes, Mulitplicities, Roles, Object Graph Mode, Coloring, Save and Load, XMI 1.1 Import from Enterprise Architect, Associations (undirected, directed, bidirected), Aggregations, Compositions, Dependency, Generalization, Multiple Virtual Inheritance (Developer Addendum: It shouldn't be too difficult to add an API for remote application control, e.g. visualize and debug a running programm. See class "ModelViewConnector".)
