What Is A Portlet?

Portlets are reusable Web modules within a Web portal Typically, a page of a portal is divided into a collection of windows, the contents of each of which is defined by a different portlet. Each portlet is intended for a simple application, such as news services, weather reports, or feature-related forums or email. As the windows, the portlets can be closed or reduced, or moved. The user who accesses the portal can then customize your personal page, adapting the contents of the same suit your needs.

A portlet is also a software application that can be placed in a web portal, which then serves as a container. It is an object that displays a box on a web page and is often issued by applets. A portlet processes the requests of a task or a particular service and dynamically generates web content displayed to the user. Portlets can provide all kinds of general or specialized services (consultation interface records, personal calendar, directory, information panel, integrating a search engine, weather, etc.)

Standards

The portlet and portal technology uses a set of standards in order to enable the development of portlets portable, or they can be used in the context of portals developed with different technologies.

The WSRP standard (Web Services for Remote Portlets) defines a standard protocol for dialogue between the portal and portlets. The Java Portlet Specification (JSR168) defines a set of application programming interfaces (APIs) for the interaction between a portlet and portlet container, a widespread deployment of Apache Pluto is JSR168 specification, and other implementations have been developed by IBM, Oracle and BEA Systems.

Among the open source implementations of portals, there are also conform to the standard Jetspeed 2 Portal Server (again developed by Apache), JBoss Portal, Liferay Portal and stringbeans Portal.

Uses Of Portlet

From the perspective of the web interface, the portlet is viewed by the user as a component that can plug in where they want a customized view of its portal. It will show information from different portlets in one page web portal with a system based panels, tabs or columns.

By respecting the portlet specification (JSR 168, JSR 286, WSRP) it is possible to use the same portlet on different portals.

In practice, a portlet is developed and deployed on a portal. The administrator who manages the web portal can then publish in a particular category to be visible to all users or a targeted population.

Portlet and Servlet

Portlets are a special type of servlet, designed to fit easily into a portal server and be executed. Unlike servlets, portlets do not have direct communication with the browser, thus can not send redirects or errors, forward calls or write markup to outflow.

Portlets are components simpler and therefore lighter. This allows for greater ease of management: they can be set, installed or removed, created or deleted and set directly by using the portal interface.

Unlike servlets, which can provide complete web pages, the portlets represent individual components, aggregated by the portal that acts as a web container. It follows that the portlet container of the portal has a more central role of the servlet container, because through it the portlets communicate between themselves, access to remote content and persistent data. Moreover, the portlet can not be reached by a specific URL, as is the portal to have associated the entire address.

• Lurker or Leecher (who is only reading the contents).
• Mod (enforcing the rules of the community).
• Netiquette (rules of behavior more or less explicit).
• Newbie (beginner, novice user).
• Nickname (user name, pseudonym, alias).
• Off-topic (Section predisposed to the insertion of messages relevant to the topics covered in the forum or message is not relevant to the topic in a particular discussion), often abbreviated “OT”.
• PM (private message, stands for Private Message).

• Troll (provocateurs are individuals who argue just for arguing).
• Warn (warning required by those with power in the forum, which would report violations of the regulation, generally has its own gauge for each user placed under the avatar).

Forum Software

Packages for the management of forums are widely available on the Internet, some free and others for a fee. Can be written in a variety of programming languages, like PHP, ASP, Perl and Java and their contents are usually stored in text files or DBMS.

Most free software is used within phpBB, and Simple Machines Forum Snitz Forums 2000, while among those in charge are vBulletin and Invision Power Board (which up-obsolete version 1.3 was available for free).

Finally, for those who did not have adequate expertise or resources needed for the installation of a software like this on a server, there are also some forums on outsourcing or the possibility of using P2P software such as Osiris appropriate to allow the creation of forums decentralized and distributed among the various nodes.

There are also free hosting services as well as a forum, think Forumfree and FreeForumZone, just to name a few.

Types of Forums:

ExBB Forum: written in PHP which stores data in text file (flat file)

Invision Power Board: Forum (fee) of Invision Power Service

Lussumo Vanilla: The sweetest forum on the web.

MyBulletinBoard: powerful free forum written in PHP

Osiris Forum: based on P2P technology which guarantees anonymity and resistance to failure.

phpBB Forum: written in PHP, allows you to store data in various types of databases.

PunBB Forum: written in PHP.

Simple Machines Forum: Free forum based on PHP and MySQL.

UseBB Forum: lightweight, simple and usable, licensed under GPL uses PHP 4 and MySQL.

vBulletin: Powerful and prestigious forum (fee) written in PHP, which stores data in MySQL database.

Organization of discussions and messages

The whole discussion is generally seen by its participants, and possibly by forum members or even anyone on the Internet.

Most forums are organized by the son of discussion (threads or topics, by amalgamation with topic, and subject, mostly in English) and displayed with an indentation. An original message launches a new thread. Then, every new reply to this thread implicitly chronological opens a new thread, as a response to a previous message. The indentations and titles of messages visualize the course of reading possible in the form of a tree, like a file manager organized into folders and subfolders.

There are two distinct possibilities of presentation: a time series model, where each message is at the same level and only follow or precede another message in time, a hierarchical model, where each message is seen as a response to an earlier message.

All the subsections of discussions are often grouped thematically, a forum that can accommodate even more thematic or even several thematic groupings.

On some forums that could be called “progressive”, an initial message determines a single thread in which all messages will follow chronologically.

A key feature of a forum is its interactivity, related to the number of people express themselves, but the number of people who read these exchanges, without necessarily reacting, is very important (they are called lurkers).

Just as the conduct of a meeting includes significant presence of a “facilitator”, the forums are sometimes “inspired” by facilitators to promote / raise trade. The hosts are also usually moderators.

Some Key Factors For Success Of Any Forum

Keep members

Wrong forum launched quickly threatens to wither for lack of adequate input to get many responses and attract readers. Factors favorable to launch a forum include:

• Obtaining a critical mass of contributions: below a minimum number of messages, one that will connect for the first time the forum is likely to find little interest in returning. However, once a sufficient number and variety of messages are least affected, the chance that everyone can find something that interests him is strong. The reverse will occur: acceleration by positive feedback: participants will talk about them, to communicate this forum, etc.
• In contrast, some forums have too many participants. Thus, the son of discussion are too numerous and are growing too quickly for participants to respond. Participants experienced generally respond to this by creating sub-sections of the forum. By cons on the forum too infrequent, there is a reduction in the number of sections so as to maintain a good level of animation.

Advertisement

Many forums are forums for publicity, whose aim is to help increase attendance at forums that it presents.

Forms

There are ways of using technology forum computer networks:

• Public forums: forums news (newsgroups, Usenet), accessible from a mailer;
• The private forums, accessible to a small group of people, e.g., on a specific site, as Mayetic Village or Yahoo groups, to create, temporarily or not a forum;
• Forums intranet and extranet, often created (intranet) within a company, organization, or team-project, but may meet (extranet) participants from various organizations, companies and associations;
• Forums Audio (on Teamspeak);
• Micro-forums, simplified version of traditional Internet forums.

Administrators and moderators

The directors are generally the managers of a forum and typically have the right to amend, delete or move any message. Usually they can also close the forum, edit it, make changes to the software, eject, delete or create users. Moderators generally help the directors, from which they were chosen, but they have less than powers. Their aim is generally to maintain a quiet and peaceful, avoiding the discussions degenerate, closing / deleting those opposed to regulation but by enforcing all the rules.

What Is An Internet Forum?

A forum on the internet is a place for public discussion (or at least open to more participants). Discussions are archived allowing for asynchronous communication (that is what differentiates the forums instant messaging). The term “discussion forum” is a tautology. Forum is a term of Latin origin and popularized by the English speaking world designating a place in the city or on the internet dedicated to the discussion and trade.

It now includes in this Usenet subject that existed before the advent of Internet and Web forums that have accompanied the development of dynamic web. We may also consider mailing lists based e-mail as forums.

Forum (plural fora in Latin) may refer to the entire IT structure in which users discuss on various topics, in response to a subsection or the software used to provide this facility. A sense of virtual community often develops around forums that have regular users and common interests.

The technology, video games, politics, current affairs and sport are popular themes, but there are forums for a huge number of different subjects. The forums are also used as tools for on-line support for various products and within companies to pool their employees and allow them to find information.

There is commonly referred to also as a forum board, message boards, bulletin boards, discussion groups, bulletin boards and the like.

Most boards require user registration before you can post messages and in some cases even to read them. Unlike chat, which is a synchronous communication tool, the forum is asynchronous because the messages are written to and read even at different times.

This place of meeting and exchange forum on what the Internet can be a website full, or just one of its components. It offers the same opportunities for discussion as Usenet, but the form and scale of a website. They are accessible via a web browser, and offer an interesting interactivity.

A forum is primarily an exchange site, through messages, as these are available on the Internet or on an internal network as an intranet or extranet. Discussions will take place in the form of “son” of messages, instant publishing or deferred; this publication is often unsustainable because the messages are not deleted. It is by nature the result of several authors. In some forums registration, messages can be changed retrospectively by their authors.

The features offered by the various forums (quotation, there are securities or not, layout / indentation, administration / permissions, moderation, a priori or a posteriori …) can vary, and may treat different forums posts: and some allow only respond comprehensively to a topic, while others can respond to a particular message.

Need For A Code Of Conduct

Most boards will require acceptance of a charter prior to participation. This charter governs the use that can be done on the forum. The webmaster is normally a function of administrator and moderator, the latter may be delegated to one or more regular users of the forum. Moderators are responsible for ensuring compliance with the Charter and limit the potential tensions between participants (e.g., by editing the message generating tension or prohibiting the sending of new messages to one participant). Some countries have adopted specific legislation that requires managers forum preventive monitoring of the content of any message.

Historically speaking, the forum is one of the oldest applications available on the Internet, and one of the most used. In fora have developed habits and customs, attitudes and generational legends. The great diversity of technical internet forum reflects its intrinsic vitality as a medium of communication modern, globalized world.

Failure to comply with the charter to use a forum (insults, xenophobia, flood etc.) can lead the moderation team to remove an account and prosecute to the ISP that will delete the user account of the person.

Types of Portal

Tourist portal

A travel portal is a special category of web portal. Like all other types of portals, it is meant to gather as much information as possible in order to satisfy the curiosity of the user on tourism in the shortest possible period of clicks. Just like the other sites of this nature, tourist portal serves as the “central tracking ‘Internet destinations minors, otherwise difficult to reach through the use of traditional search engines.

In this particular case, the smaller sites will be those belonging to accommodation facilities like hotels, farmhouses, bed and breakfast, to government agencies as common, pro-loco, associations, parks and nature reserves in ticketing services for events, a booking service and travel agencies.

Some websites of this nature simply categorize accommodations depending on geographic location, proximity to tourist attractions and quality of supply. More complete information with itineraries, addresses and opening hours of museums and sites of interest, descriptions of places and cities.

The proceeds of these portals are from the classical form of banner advertising, but mainly from tourism facilities that subscribing to services offered by portals get a custom page. This, in turn, will benefit the Page Rank and placement (usually quite high) already in possession of the portal, resulting in excellent visibility and publicity through the internet.

The services of a travel portal can usually be purchased in two ways:

• Giving a commission for each booking was through this medium;
• Subscribing paying a predetermined amount, often varies depending on the commercial packages, namely the set of required services.

Another type of travel portal can be targeted to signaling events in certain areas (municipalities, cities, provinces or even regions). A portal of events can be trained in specific events or to report any kind of events such as concerts, festivals, art exhibitions, theatrical performances and much more.

Other Examples Of Portals

Portals are often community sites that try to collect a set of services of interest to users.

The importance of a portal from the users of its community.

In the case of portals provider most popular Internet such as Orange, the community is derived from internet subscriptions provided by Orange. A significant number of subscribers to Internet service providers have as home portal for their Internet provider.

Some portals have built their reputation on a free service. Some examples: Hotmail (web mail), MSN (web mail).

The portals are built around web services (web access, email free, free directory …) and provide most of the time own editorial content tailored to their community.

A provider of Internet access (ISP) usually has its own Web portal generalist.

• Aliceadsl.fr (ISP);
• AOL;
• Free.fr (ISP);
• Google;
• MSN;
• Orange.fr (ISP);
• Voila;
• Yahoo! (ISPs in some countries);

In business, a portal can bring together and facilitate navigation between many web tools. (The internal portal of reference for a company intranet is sometimes called by abuse of language).

The portal technology also provides:

• A common graphic
• The ability to customize the page according to the user: one, according to his department, the news will be directed to him specifically, finance, technical, marketing etc.. It will only have access to tools to which it is authorized (eg financial reporting for finance, validation of expense reports for manager);
• Single sign-on: a user name and password to access the various web tools.

Some Web Portal Technologies

• Apache Jetspeed-1 and Apache Jetspeed-2
• UPortal free portal adopted by several universities and educational institutions
• Honolulu, PC SOFT is free to install
• Lutece
• Guppy
• Prometheus, an education portal free and open

• Enterprise Portals:

o BEA Weblogic portal
o IBM WebSphere Portal
o SAP Enterprise Portal
o eXo Portal
No Posh
o Liferay
o (en) JBoss portal
o Office SharePoint Server
o Silverpeas
o GateIn

What Is A Web Portal?

A Web portal, also written web portal, or Internet portal, also written internet portal, also shortened as the portal, is a website that provides a point of departure, port of entry, to a large group of resources on Internet or on an intranet.

Many portals are built and maintained with software components called ‘portlets’. The best portals allow users to customize some of their benefits. The initiative is called Open Directory Project requires that a site that wishes to be considered portal contains the following mechanisms:

A web portal can also be defined as a website that offers a unique gateway to a wide range of resources and services (email, chat, areas of publishing, search engine) focused on an area or a particular community.

Users are mostly able to register a portal to connect to it later and use all services provided, including customizing their workspace, which is organized with the help of elements of basic UMI: portlets.

Do not confuse the Web portal with a portal site institution. It is in this latter case of a site used as a pathway unique to the different sites of organizations (commercial, public institution). The portal site can direct the user to the site of the organization that best meets their expectations based on their profile.

• Search Engine / Directory (or more commonly Directory)
• Groupware and Collaboration
• Knowledge management
• Content Management
• Management of the workflow (or more commonly Work Flow)
• Facilitate multi-channels
• Signature staff
• Business Intelligence and Application Integration
• Integration with identity management
• Feature infrastructure

The major Web portals provide a wide range of benefits, services, content and distribution partnerships or cultural.

Vortal

Web portals ‘vertical’ or niche (for these it is proposed the neologism ‘vortal’) have focused on special subjects or a particular group of users and provide tools such as search engines, discussion lists and directors.

Over the past 90 years the portals have been a major commodity, a resource for widespread use. After the rapid spread of conspicuous browsers in the mid-’90s, many companies, in order to control a slice of the Internet market, have built or acquired a portal, taking into account the fact that there are many people who start their voyages from such a site.

Netscape Netcenter in the late 90s he moved to become part of America Online, the Walt Disney Company launched Go.com, and Excite became a part of AT & T, while Lycos was considered a good target for other media companies like CBS.

Many Internet portals have emerged as a director (like Yahoo!) And / or search engines (among the first Excite, Lycos, Altavista, Infoseek, and HotBot). He then expanded the provision of services in order to consolidate the user base and to lengthen their time spent inside the site.

Services that require registration of users such as free email, the procedures for customizing and chat rooms were considered useful to increase the use of the portal and then grow to increase advertising revenue.

In the early 2000s has revealed a growing industrial interest against corporate intranet portals, also known as “enterprise webs”. While the expectations of millions of unaffiliated users who turn to a public web portal has had a mediocre financial success, the adoption by a large corporation to a private portal to unify communications and internal discussions over the Web has begun to be seen by many as a technology that can save labor and money.

Most enterprise portals make available to their users performance personal signature. Some business analysts have predicted that in the first decade of the twenty-first century, spending on corporate intranets, portals will be one of the top five areas that contribute to the growth of the Internet technologies.

The industry leader in the software market for intranet portals is Plumtree Software. Other producers of enterprise portals are BEA Systems, IBM, Microsoft, Novell, Oracle, TIBCO, CommNav, adenine and SAP.

The portals are actually still in a stage of child development and have not defined the standards developed by organizations such as IEEE.
