A minimal Blog java portlet.

Copyright (C) 2012 Lucas Ponce

Objectives

miniblogportlet is a set of java portlets (based on JSR 168) to offer minimal functionalities of blogging for java portals.

miniblogportlet supports:

• multiple blogs,
• custom style based on CSS,
• internal repository,
• tagging,
• comments,
• in-line editing,
• clustering cappabilities

Portlets description:

- MinimalBlog:		Portlet to add new blog to your portal
- ManagementBlog:	Portlet to manage list of blogs of repository

Requeriments

miniblogportlet uses standard java portlets, so it can be migrated easily to any standard PortletContainer based on JSR 168 or JSR 286 standards.

miniblogportlet uses JBoss Cache for internal repository with clustering cappabilities.

miniblogportlet has been tested with JBoss Enterprise Portal Platform 5.2 based on GateIn with "all" type instance.

You can get JBoss EPP 5.2 from here:

https://access.redhat.com/downloads/evals

Installation

Steps:

- [1]	Update build.properties with the path of your jboss-epp-5.2 home and with your "all" based instance name.
- [2]	ant install to compile and deploy minibloglib.jar into $INSTANCE/lib folder and miniblogportlet.war into $INSTANCE/deploy folder.
- [3]	Start your instance
- [4]	Take a look into minitutorial about how to create new portal pages with MinimalBlog portlets and start creating blogs.

Configuration

miniblogportlet uses JBoss Cache as repository, and it's configured into the following path minicmsportlet.war/WEB-INF/miniblog-jboss-beans.xml.

JBoss Cache is configured to use a local folder as cache loader, this folder can be configured with a java system property

-Dminiblog.data.dir=<path to your folder repository>

miniblogportlet is a really simple piece of code, you can easily adapt it to your needs.

JBoss Cache is not mandatory, you can rewrite your own repository just adding an implementation of the following interfaces:

- blog.services.BlogAPI
- resources.services.ResourcesAPI

You can take:

- blog.services.CacheBlogImpl and 
- resources.services.CacheResourcesImpl 

as examples of implementations but the aim of this design is to add different implementations in a simple way.
