Demo

10.  Portlet Modes
−View (default mode)
−Edit (Reserved for changing the Portlet‘s settings)
−Help (providing information about the portlet)
−etc.
 Request Modes
−Rendering (default mode for viewing the Portlet‘s contents)
−Action (normally used for state changing actions)
−Resource (used for serving resources)
Portlet Rendering

11.  Portlet MVC Architecture
−Configuration is usually done using singleton Beans
−Model is defined as Entities (not used here)
−Controllers are configured using annotations, using beans via CDI
−View is configured by the viewResover, selected by the controller
Spring Model

12. Code
Walkthrough

13.  Build Java services, and deploy within the Portlet
−Pro: still hot deployable Processes using WebForm
−Con: still only deployed services are usable
 Improved error handling
−Think of timeout escalation, tasks already done, but page not
refreshed, etc.
 Use Liferay Users for Camunda
 Assign Processes to Users/Groups
 Substitute Kaleo (the default Liferay Workflow Engine) with Camunda
Possible improvements

14. Process Applications vs. „Kaleo“
Use Liferay as UI for
Process Application
Internal Workflows in
Liferay (e.g. release
