jUCMNav v3.2.1


New visualisation of metadata, stereotypes, and links:



Update site (recommended)

  • In Eclipse: Help -> Software Updates -> Find and Install -> Search for new features to install -> New remote site:
  • See the animated Installation Demo
  • Important Notes
    • On Eclipse 3.4, select both the new jUCMNav update site and the Europa Discovery Site
    • On Eclipse 3.3, you might need to expand the Europa Discovery Site before clicking on "Select Required" (dependencies)
    • Using the update site is needed if you want the MSC Viewer plugin to be installed properly. Afterwards, the jUCMNav and MSC Viewer plugins can be updated manually from binaries.
    • Eclipse does not allow automatic upgrades between major revisions. jUCMNav v2.* will need to be uninstalled before proceeding with the installation of jUCMNav v3.*

From binaries (not recommended)

  • Download v3.2.1 here (jar).
    • Make sure your browser does not rename the .jar file to .zip or anything else.
  • Other files (src, javadoc)
  • 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.


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!)



  • Version
    • jUCMNav 3.2 requires Eclipse 3.3 or Eclipse 3.4 or Eclipse 3.5
  • Distributions
  • Plug-ins required for running jUCMNav
    • jUCMNav 3.2 requires the Eclipse EMF, GEF, JDT, RPC, OCL, and Platform plugins.
    • Users should use the jUCMNav update site to get these dependencies automatically.
    • Otherwise, they can be obtained from the Europa Update Site or from their respective projects
  • [Optional] Additional plug-ins required for compiling jUCMNav


Release Notes



  • End-user documentation is integrated with the Eclipse help system. Access Help > Help Contents from the Eclipse workbench, then select topic jUCMNav Online Help.
  • The latest user documentation can also be accessed via Help On Line

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 3.2.0

  • NEW Visualization of importance attributes (GRL), URN links (GRL) and metadata (GRL/UCM)
  • NEW URN link indicators for GRL elements, support for stereotypes, and tool tips for model elements that have descriptions, metadata and/or URN linkswith tool tips for descriptions, metadata, and stereotypes (URN)
  • NEW New colours for GRL evaluations, more pastel, which lead to better printouts. Also changed white to grey for Unknown evaluations.
  • NEW Scenario definitions in the scenario group named Init are now skipped when running all scenarios (including during MSC export). This Init group is hence a good candidate for defining partial scenarios that are included elsewhere but that are not meant to be run standalone.
  • NEW Partial support for user-defined metrics (in OCL) computed on URN models
  • Various bugs and UI-related issues:
Bug Description
548 Metadata indicator for URN elements
637 Display error in GRL qualitative/mixed evaluation
638 Deleting an unnamed start/end point creates exceptions
466 Some support for responsibility reference copy-paste (alpha!)
? Fixed GRL actor evaluation for quantitative/mixed algos (now just a simple weighted average based on importance of intentional elements).

Enhancements / Fixes since 3.1.0

Enhancements / Fixes since 3.0.0

Bug Description
550 Error when undoing the deletion of a GRL element
554 Strategies export to .csv files do not handle commas in descriptions
556 In the Stub Bindings window, plug-in condition expressions' && are replaced with &
555 Belief descriptions not duplicated properly when duplicating a GRL diagram
551 Report when transforming a non-well-nested UCM
552 TOC links in the on-line help refer to the TWiki site
535 And/Or decomposition context menu item
559 Invalid thread access when exporting a URN model without scenario definitions
561 Invalid default value for Preferences under Linux
409 Export wizard + multi-map select
332 Image export: should try to trim exported images
329 Progress meters for wizards

Known Issues in 3.2.1

  • Reports generated, MSC Viewer, and user documentation only available in English.
  • Reports do not include information on GRL elements or UCM scenario definitions (and MSCs)
  • 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.
  • Deleting a map whose start point is referenced in a scenario definition causes saving the file to complain.
  • There are no extension points to give your own scenario/strategy algorithms and no UI to choose them.
  • Memory leak. With very large diagrams (30+ complex maps), you might only be able to open it half a dozen times before you run out of memory. Restart Eclipse to clean memory or increase JVM heap space until we find the memory leak source.
