The Open Source Advantage
Open source puts your business at the center of your technology initiative. Your product can
be customized to the specific needs of your business without tying you in to any specific
vendor and their associated license costs.

Open source is a superior development
model that leads to more robust code,
increased innovation, and faster
development cycles.

Each customer’s investment in the
product is multiplied to the entire user
community. The ROI on your
participation is multiplied exponentially

Zero-cost licensing allows that budget to
be applied toward customization,
resulting in better user acceptance and a
product that fits your business

Open source means flexibility and control
– the code is in your hands and ready to
customize

Lower risk – Any vendor, open source or
commercial, can change course and
discontinue product support. Open
source ensures you have access to code
regardless of vendor strategy

Business Needs
Enterprise Intranet
Liferay Portal provides the tools needed to give users secure access to sensitive company
information and applications. Liferay not only manages groups within an organization (for example,
Executives, Marketing, Human Resources), it also ensures that people within those groups only
see what they're allowed to see.
Meanwhile, a Liferay administrator can get applications and content to the whole portal community
quickly and easily without having to maintain several different sites.
Business Needs
Corporate Extranet
Liferay Portal helps an organization create secure websites (extranets) for its clients or partners. For
example, a supplier of aftermarket automobile parts may work with several retail resellers that need to
access the company's inventory to order parts and check shipment status. Liferay makes it easy to
manage each reseller's access rights, content, and functionality, and quickly create branded extranets
for new resellers.
Business Needs
Web Publishing and Content
Management
Effective content management systems
(CMS) are a vital part of any organization.
In fact, content management is a natural fit
for a portal because of the need for secure
access and permissions (ie, who should be
able to delete a document from the
system?), distinct roles (writer, editor,
designer, administrator), and workflow
(edit, approve, publish).
Liferay Portal offers a built-in web
publishing and content management
solution, featuring full roles-based editorial
workflow, localization support, templates for
quick layout changes, and integrated
portlet-based publishing. It also offers a
standards-based document library to store
Office, PDF, image and other files.
Business Needs
Liferay Portal offers comprehensive
tools to help developers integrate
enterprise assets with an
integrated enterprise service bus,
workflow engine, web services
support (SOAP and REST), and
developer tools like an Eclipse
plug-in and Liferay Service Builder.
Liferay's coming Content
Interaction API will be designed to
create a unified interface for
working with content in Liferay
Portal regardless of source. Users
will be able to manage and publish
content from third-party systems
like Alfresco, Magnolia, Microsoft
Sharepoint, or Vignette with the
same interface used for Liferay's
built-in CMS.

Contains the main configuration options
Contains explanations for each prop.
Can be extended through

Contains the system related options
Can be extended through

Each theme can be applied to



Each community website
Each page within the website
Layout Templates




of the page where portlets can be
placed
Developed in Velocity
Most used configurations provided
out-of-the-box
Portlet Development
Direct JSR-286 API


Similar to servlet but two phases
Bridges to existing tools


Struts, PHP, Ruby
JSF


Liferay provides examples for SUN RI,
MyFaces and ICEFaces
New frameworks include support for
portlets


Struts 2, Spring MVC
Developing a portlet
public class HelloWorld extends GenericPortlet{
protected void doView(
RenderRequest request,RenderResponse response)
throws PortletException, IOException {
response.setContentType("text/html");
response.getWriter().println(
"Hello world Portlet");
}
}
Developing a portlet


/WEB-INF/web.xml
/WEB-INF/portlet.xml
<portlet>
<description>HelloWorldDescription</description>
<portlet-name>HelloWorld</portlet-name>
<display-name>Hello World</display-name>
<portlet-class>com.test.HelloWorld</portlet-class>
<expiration-cache>-1</expiration-cache>
<supports>
<mime-type>text/html</mime-type>
<portlet-mode>VIEW</portlet-mode>
</supports>
<supported-locale>en</supported-locale>
</portlet>
Developing a portlet
Understanding the two phases


Action: modifies state


The portal should not reinvoke it
Render: only shows content


The portal can invokes it many times
The portal can cache the result
Developing a portlet
public class HelloWorld extends GenericPortlet{
protected void processAction(
ActionRequest request,ActionResponse response)
throws PortletException, IOException {
String name = request.getParameter(“name”);
String msg = request.getParameter(“msg”);
SignBookService.addHello(name, msg);
response.setRenderParameter(“success”);
}
}
Legacy App Integration
Strategies for integrating existing
applications:






Iframe based solution
Proxy
Portlet bridges
Portlet as entry point or summary
Convert to portlet
SSO solutions:




Basic auth
Form
CAS
Extension Points

Most used provided through
portal.properties
 Example: authentication
Full customization through Spring



ext-spring.xml
Allows creating a custom:




Implementation of any service
Implementation of persistance classes
Transaction Manager (JTA)
DataSource configuration
Reusable Services
When developing on top of Liferay
keep in mind:




Most of Liferay's functionality is
provided through a Business Service
Layer
The Service Layer can be invoked
through Java, Http, SOAP, ...
You can create your own services with
ServiceBuilder
Most used services


UserService, GroupService
Conclusions
Use a portal platforms when several
applications have to be integrated
Portals offer advanced services: use
them
Out-of-the-box functionality allows
you to:






Get to production very fast
Concentrate on what matters you most
Extensibility is a key feature of a
portal platform
