    Jadecy

    Java lib to compute (code) deps, SCCs, and cycles (Johnson algorithm).

    Jadecy (Java Dependencies and Cycles) is a Java library to compute dependencies (elements depended on, or depending), strongly connected components, and cycles, in general directed graphs, or classes or packages dependencies graphs parsed from class files (major version <= 52, else does best effort). It uses Tarjan's algorithm for SCCs computation, and Johnson's algorithm for exhaustive cycles computation, with continuations instead of recursion, which allows to handle large graphs (< 2^31 vertices). Since version 1.1, can also compute shortest cycles covering all edges of SCCs. Usage from command line is also possible but with reduced flexibility (cf. JadecyMain class). API entry point for Java code dependencies is the Jadecy class, or DepUnit that makes use of it and is designed for unit tests. API entry point for general graph computations is the net.jadecy.graph package. Requires Java 5 or later. Also available on github: https://github.com/jeffhain/jadecy

    Jedi

    Jedi

    Java Enhanced Data Interface - Italian Senate Project

    JEDI is a J2EE application that provides a centralized service aiming at significantly simplify the generation of data driven documents in a enterprise environment. The documents (hereafter called "JEDI documents") can have different format types: pdf, excel, rtf, plain text data streams and xml streams. A JEDI document is an instance of the so called "managed document" (i.e. the configuration data and a particular set of rules), configured by a developer into the JEDI configuration database. The provision of a JEDI document is based on a synchronous processing performed by the JEDI core engine triggered by an end-user request (through HTTP request or RMI call). The content of a JEDI document (i.e. the input of the JEDI service), must be an XML stream regardless of the source. Such data is subsequently processed through one or more XSL transformations in order to provide the user with the document in the required format.
