This site contains information about the dependencies of JWT's components, as well as a description on how to download the latest versions from the Eclipse SVN and the layout of the JWT SVN repositories.

Access the JWT Source Code

Browsing it online

You can browse the SVN repository online at [1].

Donwload it

To download the latest source code of the various components of JWT, please connect your SVN client (typically Eclipse's SVN Browsing perspective) with:

If you have a committer account, please provide your committer data (username and password) and select as connection type svn+ssh://dev.eclipse.org/svnroot/soa/org.eclipse.jwt .


In this SVN repository, the source code of JWT is under the "org.eclipse.jwt" directory, which you can retrieve by doing a SVN checkout. It is laid out as follows:

Essential stuff:

  • org.eclipse.jwt/metamodel : Meta Model, the JWT meta model
  • org.eclipse.jwt/we : Workflow Editor, i.e. design time tools

Optional stuff:

  • org.eclipse.jwt/we-plugins : Workflow Editor Plugins, e.g.. additional views
  • org.eclipse.jwt/transformations : Transformations, e.g. to/from BPMN, XPDL, ...
  • org.eclipse.jwt/examples : Examples, demonstrate how to extend JWT

Releng stuff:

  • org.eclipse.jwt/releng : Release engineering, required for building the JWT feature

Additional components:

  • org.eclipse.jwt/wam : Workflow Audit And Monitoring, i.e. runtime time tools and framework
  • org.eclipse.jwt/desktop : Simulator and other standalone BPM tools

For a more detailed layout please refer to Detailed Layout of the SVN.


Dependencies (for SVN TRUNK as of July 2010 / JWT 1.0.0)

Below is the easiest way to get an Eclipse environment with all dependencies for this JWT version.


Install Eclipse 3.6 (Helios) and a Java Runtime Environment (JRE) / Java Development Kit (JDK) 5.0 or higher.


Add the following plugins :

  • EMF - Eclipse Modeling Framework SDK
  • Graphical Editing Framework Draw2d SDK (GEF)
  • and its Graphical Editing Framework Zest Visualization Toolkit SDK extension
  • ATL SDK - ATLAS Transformation Language SDK

Those plugins' SDKs are optional but may be useful for developers.

If you already have Eclipse installed, you can download those plugins from from your "Software updates" menu.


Add the following Orbit dependencies :

  • org.apache.xalan 2.7.1 - tag (branch) : v2_7
  • org.jdom 1.0 - tag (branch) : v1_0

To work with them in your workspace, follow the steps described here, with additional in depth information here.

In our case, simply check out in your workspace each module described above from the Eclipse Tools CVS repository:

  • host: dev.eclipse.org
  • repository: /cvsroot/tools
  • module: org.eclipse.orbit/org.jdom
  • Tag: use the appropriate tag corresponding to the version mentioned above. You may get the tag by browsing the CVS repository in Eclipse, doing a right-click > "Configure Branches and Versions" on the dependency folder, selecting the right tag and finally clicking on "Add Checked Tags".

Start working with the code

Build the JWT Code

You need to retrieve the JWT source code by checking it out from SVN after having installed its dependencies, as described above.

If you used an external SVN tool to check out the codebase, you need to import the source code into Eclipse as projects (in the Java Perspective, using right click > import existing projects). Look below to know which projects are required to be imported.

The build will start automatically once you've imported the projects (thanks Eclipse !). If you've got all required dependencies (see above), once the build is finished, all projects should be built with no remaining error (red tags), like in the following picture :

If you've got errors, they are usually about dependencies. Maybe you haven't imported enough JWT projects, or maybe you've imported "obsolete" parts of the SVN codebase. Again, look below to know which projects are required or obsolete in the codebase.

Run the JWT Plugins from Code

Right click on the jwt-we project and choose Run as > Eclipse application. This will launch JWT-WE with all plugins that are available in the workspace. If Eclipse does not succeed to start or JWT-WE is not active, please ensure that all necessary plug-ins are configured to start with your projects. To do so, click on the arrow in the Run item in toolbar, and choose Run Configuration....

Select/Create a run configuration (Eclipse Application) for JWT-WE and on the Plug-ins tab select all necessary plug-ins (in case you have doubt, select Add Required Plugins). Workflow Editor plugins (e.g. the Documentation Generator plugin) must also be enabled in order to be available at run time.

You can now use the Run item in the toolbar to start your new configuration.

Debug JWT

There are two alternatives.

1. (the most common) As a developer, you'll want to debug your code and the JWT code you build on. To do so, do as above but using Debug as > Eclipse Application rather than Run as.

2.Sometimes, a JWT release (packaged in an Eclipse release, or a custom RCP release) will have a different behaviour than when started from workspace plugins as above. You can debug it using java remote debugging. To do so,

  • add to the startup executable (ex. "C:\eclipse\eclipse.exe") of the Eclipse + JWT installation you want to debug the following command line arguments :
-consolelog -clean -debug -vmargs -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
  • once started, connect your development Eclipse to it, by right-clicking on Debug as, creating a new, properly configured Remote Java Application if required and hitting "enter".

Run the tests

Make sure you have already checked out the releng/jwt-test-plugin project.

To run all the tests, Checkout the releng/jwt-test-plugin project, right-click on it and choose "Run as..." > "JUnit Plugin Test".

To run a given JUnit test, right-click on its class and also choose "Run as..." > "JUnit Plugin Test" (AND NOT "JUnit Test")

Structure of SVN

  • All projects start with jwt.
  • Afterwards the main component is added jwt-we, jwt-transformation or jwt-wam.
  • If an example is visible in a specific area it is named jwt-we-XY-example (for an example using an extension point of the workflow editor).
  • The package structure is org.eclipse.jwt.component and for additional plugins org.eclipse.jwt.component.plugins.nameexample, e.g. org.eclipse.jwt.we.plugins.viewexample.
  • Versioning: It is always x.y.z where x and y are always consistent with the corresponding JWT version and z is reserved for the different versions of the plugin in one release, e.g. 0.4.1 for JWT release 0.4 and first change of this additional plugin.
  • In SVN there will be a main directory for each component jwt-we, jwt-transformation, jwt-wam and jwt-we-plugins where all additional plugins can be found.
