Hi Folks,
With the recent work on OODT-70 [1] to add support for wengine-style workflow
XML files
to trunk/workflow, the trunk/workflow manager can now load up and execute
wengine-style workflows.
To enable this feature (which only exists in 0.4-SNAPSHOT), download and build
a fresh version of trunk, and then grab the workflow manager deployment from
there
and edit $WORKFLOW_HOME/etc/workflow.properties:
- Edit # workflow.repo.factory and set it to
org.apache.oodt.cas.workflow.repository.PackagedWorkflowRepositoryFactory
- Set the following property:
org.apache.oodt.cas.workflow.wengine.packagedRepo.dir.path to the root dir
path to a directory with wengine-style
workflow files. You can comma-separate the paths and it will load all
wengine-style XML files from each dir path
specified (and comma-separated)
Reboot your workflow manager ($WORKFLOW_HOME/bin ; ./wmgr start) and your
workflows
should now be loaded. A couple of notes (from [1]):
1. Sub-workflows are supported by an inline BranchEventTask that sends an Event
to kick off sub-workflow. The
dynamic Events are built and added to event repo.
2. Parallel workflows are supported right now with event mapped to single-task
workflows.
If you're interested in the progress of the Workflow2 integration with trunk,
see OODT-215 [2]. Comments, help,
thoughts, patches, welcome :-)
Cheers,
Chris
