Java standards portlet

WHAT IS A JAVA PORTLET?

• There are two JSR standards that govern portal/portlet behavior.
• JSR-168 is the Portlet 1.0 Specification.
• It was created out of a need to have a specification for displaying multiple applications on the same page.
• JSR-286 is the Portlet 2.0 Specification which retains backwards
• compatibility with 1.0 (JSR-168) portlets.
• Adds new features based on the experience of the different portal vendors.
• The portlet specification defines the life cycle of a portlet as well as its characteristics.

BENEFITS OF JAVA STANDARD PORTLETS

Core Architecture :

• The core architecture will be the same across Java Standard compliant portals.
• Portlets written to the standard will run on all compliant portlet containers.

Documentation :

• The Portlet Specification will not change, and you can reliably refer to it for information.
• Standard Portlet API for developers.

Liferay to build online environments for regulatory organizations

By Victor Zorin, Enterprise Architect – MyOffice24x7 Pty Ltd
 

(As presented at the Liferay Symposium, San Francisco , 2012)

Challenges of regulatory environments

What is a regulatory environment? One example is an Australian statutory authority that administers state gambling and liquor laws, including management of licensing and compliance.

We had already worked with them to produce a Liferay-based intranet for employees and several specialised extranet portals.

They wanted us to help them come up with an improved way of managing the issuing and renewal for each of their  100+ types of licenses, which were all currently in paper/scanned format. We discovered that the one major challenge faced by these types of organisations is that end users (customers, applicants) expect an uncomplicated, easy to use, and unified front with which to interact BUT regulatory organisations by nature are comprised of a large number of highly disconnected business stakeholders.

Using Liferay Portal as an e-Learning Platform

How to use Liferay Portal 6.x to help deliver digital training to your organization affordably and effectively.

Our goal is to show you how Liferay Portal can be used to build a facility where trainees or students are able to undertake
structured, sequenced coursework under the supervision and assessment of managers and mentors.

Why Liferay?

Liferay Portal does not ship as an e-Learning product, but it does provide

a solid foundation for one:

·          Strong CMS (content management) functionality: its user, role and community
facilities are already well suited to this task.

·          Attractive set of collaboration portlets (wikis, discussion boards, blogs etc) that ship
with the portal.

·          Easily extensible thanks to JSR-168/286 compliance.

Liferay Portal is capable of delivering many of the facilities offered by existing e-Learning products such as Blackboard or Moodle without the associated costs or troubles.

Filling in the Gaps

Liferay Portal is clearly missing some functionality when it comes to achieving our initial goal:

“... a facility where trainees or students are able to undertake structured, sequenced coursework under the supervision and assessment of managers or mentors”

Our priority in conceiving this e-Learning platform is to maximally take advantage of whatever functionality is offered to us by Liferay Portal (or third-party extensions).

Functionalities that are lacking in Liferay Portal:

·          A facility for students/trainees to undertake exercises or ‘lessons’.

·          Facilities for course administrators and supervisors to monitor progress and undertake assessment of completed exercises.

·          A way to implement a community-module-exercise hierarchical structure (Liferay Portal communities cannot really do this natively).

Useful Patch for Liferay 6.1.1 GA2 - By Juan

Hi Everyone,

I was just looking out some solution for the problem which is coming out during migration and i found this forum article.

Nice forum article by Juan !!!!
It's really helpful to lookout and solve many issues for Liferay 6.1.1.

He is been doing some years ago, he has  released a patch for solving many issues for 6.1.1 GA2. He has tried to patch only bugs, not improvements.

For patching just unzip the .diff file into liferay 6.1.1 source folder (same folder level as portal-impl, portal-web, etc folders) and use patch command in Linux or other tools for Windows. After that just compile and enjoy!

Example on how to apply patch in Linux: patch -p0 < patch_6.1.1_juan.diff

Liferay CRUD portlets with XMLPortletFactory - By Jack Rider

One of the first tasks you find in a project is to create support for the persistence layer, say for example products, clients, suppliers table. This usually accounts for a big load of hours, not to say if you find your self with late changes with fields, versions, requirements....etc

Luckily Liferay developers have this open source tool called XMLPortletFactory, that creates complete portlets with just a small XML definition file, were you can control and implement a load of parameters like:

Maven build with liferay

Nice tutorial by http://www.eusia.info

Have a look !!!


Assuming that you have JDK and Maven set up in you machine, I will write here how we can have a liferay project in minimal effort and make it distributable in all environments.

We will use Maven archtype plug-in to create liferay project.

Consider a folder as your project home, like: /home/manna/examples/liferay

if you working with maven you can have several maven settings based on project requirements, so better to have a different maven settings file like here we have : /home/manna/.m2/eusiaweb.xml

<settings>
    <profiles>
        <profile>
            <id>examples</id>
            <repositories>
                <repository>
                    <id>sonatype</id>
                    <url>http://oss.sonatype.org</url>
                    <snapshots>
                        <enabled>false</enabled>
                    </snapshots>
                </repository>
                <repository>
                    <id>maven</id>
                    <url>http://repo2.maven.org/maven2</url>
                    <snapshots>
                        <enabled>false</enabled>
                    </snapshots>
                </repository>
            </repositories>
        </profile>
    </profiles>
    <activeProfiles>
        <activeProfile>examples</activeProfile>
