    • Note: Using the update site is required if you want the MSC Viewer plugin to be installed properly. Afterwards, the jUCMNav and MSC Viewer plugins can be updated manually from binaries.
    • Note 2: Eclipse does not allow automatic upgrades between major revisions. jUCMNav v2.* will need to be uninstalled before proceeding with the installation of jUCMNav v3.*

  • Eclipse
    • jUCMNav 3.0 requires Eclipse 3.3
      • jUCMNav 3.0.0 still functions properly on Eclipse 3.2, the only minor feature which does not work is PNG export.
    • We recommend you download the Obeo distribution of Eclipse; the Europa Modelling bundle already comes with GEF and EMF.
  • The Graphical Editing Framework
    • jUCMNav 3.0 requires GEF 3.3
    • We recommend you download the SDK or runtime.
    • This can be installed through the Eclipse update function, select the "Europa discovery site" update site already listed.
  • The Eclipse Modeling Framework (EMF and SDO)
    • jUCMNav 3.0 requires EMF/SDO 2.3
    • 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 "Europa discovery site" update site already listed.
  • The Web Tools Platform (WTP) NEW
    • jUCMNav 3.0 requires WTP 2.0 for use of the new Key Performance Indicator (KPI) features.

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.
  • Additional help for DOORS Export is available
  • Additional help for CSM Export is available

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 2.4.1

  • Key Performance Indicator (KPI) modelling and monitoring support.
  • Strong improvements to generated MSC validity and robustness.
  • Enhancements to the MSC visualization engine. MSCs now more compact.
  • Fixed issue with MSC export not working depending on new jUCM file wizard
  • Various minor UI-related issues.
  • Export diagrams to PNG (finally!)
  • Prototype integration between GRL strategies and UCM scenarios
  • Upgraded the French version of jUCMNav.

Known Issues in 3.0.0

  • Autolayout still a prototype
  • User documentation not translated yet.
  • User documentation only partially reflects integration of GRL and scenarios.
  • There are no extension points to give your own scenario/strategy 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.
  • 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.
