jPDL


Follows are very simple jPDL examples which may be deployed to the Alfresco Repository and stepped through via the Workflow Console.

To deploy any of the following:


  1. Copy the jPDL sample to a file in your Application Server classpath e.g. alfresco/WEB-INF/classes/alfresco/workflow/simplest.xml
  2. Launch the Workflow Console
  3. Deploy the jPDL sample via the deploy command e.g. deploy alfresco/workflow/simplest.xml
