  • In Eclipse: Help, Software Updates, Find and Install, Search for new features to install, New remote site:

From binaries


Operating Systems

  • Windows XP (tested) :check:
  • Linux (tested) :check:
  • MacOS X (tested) :check:
  • Any other O/S on which you can run Eclipse (currently untested - please report your success!)



  • For more in-depth information and a guide about installation of prerequisites, see Dev Doc Deployment.
  • Eclipse
    • jUCMNav 2.3 requires Eclipse 3.2
    • We recommend you download the Eclipse SDK.
  • The Graphical Editing Framework
    • jUCMNav 2.3 requires GEF 3.2
    • We recommend you download the SDK or runtime.
    • This can be installed through the Eclipse update function, select the "Callisto discovery site" update site already listed.
  • The Eclipse Modeling Framework (EMF and SDO)
    • jUCMNav 2.3 requires EMF/SDO 2.2
    • We recommend you download the SDK or runtime, but make sure you get EMF and SDO; the plugin will not work otherwise.
    • This can be installed through the Eclipse update function, select the "Callisto discovery site" update site already listed.
  • [Optional] GraphViz dot

Release Notes


From update site:

From binaries:

  • Download and install all prerequisites, then copy the jar file into your /eclipse/plugins/ directory. Restart Eclipse.
  • If you've installed jUCMNav from a latest build instead of an official release, make sure you remove the latest builds.


  • End-user documentation is integrated with the Eclipse help system. Access Help > Help Contents from the Eclipse workbench, then select topic jUCMNav Online Help.

Reporting Bugs / Usability Requests

  • Send your bug reports to
  • Include reproduction steps, sample .jucm files and, if applicable, copy-paste the error log messages.
  • If you're zealous enough, we'll create a BugZilla account for you smile

Enhancements / Fixes since 2.2.2

  • Metadata on all URN model elements (see the URNMeta Model)
    • You can define your own metadata on any path node, intentional element, etc. These string / value pairs are intended to be used when writing your own custom plug-in to jUCMNav that needs extra information to do its job. An example would be a test case exporter which would require a few setup parameters to drive the output.
    • Many thanks to Pengfei Chen for this addition!
  • Scenarios
    • Traversal algorithm is now more robust, supports multiple threads, knows about the component context in which a path node is being run.
    • Hit count no longer algorithm dependant.
    • Created infrastructure to support:
      • Scenario Traversal Listeners
      • Other scenario traversal algorithms (strategy design pattern)
  • Added export to MSC plug-in to jUCMNav.
    • Based on the work done by Daniel Amyot and Ali Echihabi for UCMNav.
    • Actually exports to *.jucmscenarios, the XML serialization of an EMF-based meta-model which clean-ups up the XSLT-related elements required by UCMExporter
    • It can also export its intermediate steps as a *.jucm file representing a flattened UCM and another *.jucm file representing the well-formed (in terms of concurrency) linear representation.
  • Now packaged with an MSC Viewer (written by Alex Boyko, Tolik Boyko, Max Kovalenkov, and Tafiqul Abumohammad, CSI 4900 (Winter 2005))
    • Plus a few bug fixes and a new import layer to support *.jucmscenarios.
  • New feature: run all scenarios in group. You can now check the coverage of a group of scenarios with a simple click.
  • Duplicate UCM / GRL diagrams.
  • Connects were not always properly deleted, preventing files from being re-opened (Thank you Mathieu Bertrand, Gabriel Craig Lanoix, and Daniel Amyot for the lenghty debugging!).
  • Visibility of GRL contribution icons and text now can be set via jUCMNav's main preference page. (partial resolution) (Thank you Daniel Amyot!)
  • Misc bug fixes, usability enhancements, code cleanup.

Known Issues in 2.3.0

  • Autolayout still a prototype
  • User documentation not translated yet.
  • User documentation only partially reflects integration of GRL and scenarios.
  • Duplicate map / grl diagram does not set IDs for the new elements.
  • There are no extension points to give your own scenario/stategy algorithms and no UI to choose them.
  • Visibility of GRL contribution icons and text now can be set via jUCMNav's main preference page, but open editors are not automatically updated. You need to reload the model.
  • Bug in export to MSC: If none of your scenario elements are not contained inside a component reference, the exported MSC will fail to open. Workaround: associate at least one of your responsibilities to a component reference.
    • The generated "Environment" component dissapeared if it did not communicate with another component, even if it contained elements such as responsibilities.
