It is an intuitive process language to express business processes graphically in terms of tasks wait states for asynchronous communication timers and automated actions. To bind these operations together jPDL has the most powerful and extensible control flow mechanism. jPDL has minimal dependencies and can be used as easily as using a Java library. jPDL includes a graphical designer tool. The designer is a graphical tool for authoring business processes. It s an eclipse plugin. Workflows can be performed either by handcoding XML or by using the JBoss jBPM Process Designer tool. In the later sections we will see both the approaches. Workflow process Whenever content is created or modified for a web project it is added under Modified Items of a user s sandbox. A list of modified items in a user s sandbox can be promoted from a sandbox to a Staging Sandbox. Content is promoted from a user s sandbox to the Staging Sandbox by initiating the Submit Wizard. This wizard is initiated by clicking on either the Submit Selected or Submit All actions in the Alfresco web client. Submitted changes are routed via workflow for one or multiple users to review and approve either serially or in parallel using Alfresco s out-of-the-box Web Site Submission workflow or any custom-built WCM Workflow . Once approved a snapshot is automatically taken of the Staging box. The workflow process can be divided into three steps. 1. The first step is to define and deploy a workflow in WCM. 2. The second step is to associate the workflow to a web form or web project. 3. The third step is to submit modified content to the staging server using a workflow. 162 Download from Wow eBook www.wowebook.com Chapter 5 Out-of-the-box workflow .
