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

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

Code

Walkthrough

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

Process Applications vs. „Kaleo“

Use Liferay as UI for Process Application

Internal Workflows in Liferay (e.g. release

content) vs.
