Remote Portlet Application Deployer
-----------------------------------
Key: JS2-644
URL: https://issues.apache.org/jira/browse/JS2-644
Project: Jetspeed 2
Issue Type: New Feature
Components: Deployment
Affects Versions: 2.1
Reporter: Shinsuke SUGAYA
Assigned To: Shinsuke SUGAYA
Fix For: 2.1
Overview
--------
Remote Portlet Application Deployer(RPAD) deploys a portlet from remote
portlet repositories into a Portal server, such as Jetspeed2, directly. RPAD
consists of 2 parts: RPAD API and RPAD Portlet. RPAD API defines the
programing interface to access to remote portlet repositories. RPAD Portlet
provides JSR 168 compliant portlet to deploy a target portlet from remote
repositories.

Class Description
-----------------
RPAD API:
Class org.apache.jetspeed.portlets.rpad.RepositoryManager
RepositoryManager manages Repository instances. Portal, such as Jetspeed2,
calls methods of this class to access remote portlet repositories.
Interface org.apache.jetspeed.portlets.rpad.Repository
RPAD supports a variety of kinds of portlet repositories. A portlet
repository needs to implement this interface. Repository manages
PortletApplication instances for a remote portlet repository.
Portal can access portlet information in a remote portlet repository via
this class.
Class org.apache.jetspeed.portlets.rpad.PortletApplication
This class has properties of a portlet application, such as a portlet name,
url to download war file.
Class org.apache.jetspeed.portlets.rpad.simple.SimpleRepository
SimpleRepository is a file-based repository. If a portlet provider puts
a repository site descriptor for a remote portlet repository, using
SimpleRepository, the provider delivers portlets to a Portal server.
The syntax of the repository site descriptor is under discussion with
PRP(https://prp.dev.java.net/). We will define it by the first week of
Feb.
RPAD Portlet:
The current implementation is JSF-based portlet.
Class org.apache.jetspeed.portlets.rpad.portlet.RPADPortletFilter
RPADPortletFilter initializes RepositoryManager instance.
Interface org.apache.jetspeed.portlets.rpad.portlet.deployer.PortletDeployer
RPAD Portlet calls PortletDeployer#deploy(PortletApplication) to deploy
the target portlet into your Portal. If you implements PortletDeployer
class for your Portal, RPAD works on your Portal.
Class
org.apache.jetspeed.portlets.rpad.portlet.deployer.impl.JetspeedPortletDeployer
This class is PortletDeployer implementation for Jetspeed2.
TODO IN THE FUTURE
------------------
- Manage a portlet version in J2
- Store portlet information to DB, not memory
- Move RPAD to under Apache Portals sub-project for other portals to use RPAD
