Liferay 2014 Marketplace App Contest

_It's back! _To celebrate and reward our outstanding community of Marketplace developers, I am happy to announce the opening of the 2014 Liferay Marketplace App Contest! Last year, we had over 70 submissions and many winners (so many that we had to extend the review period an extra week). We saw some really great and innovative apps, and also saw a nice bump in Marketplace activity in general. Last year's winners saw an average of 7x increase in downloads and 2000+ views! So while the prizes are nice, the increased visibility (and bragging rights) are even sweeter. So we're doing it again.... read more

Inject any custom class or service into web content templates

Problem situation

Web content templates are easy to write in Liferay, but as they become more complex they tend to contain a lot of scripting. Moreover, complex Velocity or Freemarker scripts are hard to maintain and even harder to debug. Also, unit testing your scripts is impossible.

Macros

A first possible optimization is to use macros. Generic script blocks can be captured into a macro so the same logic can be used multiple times in your script. You can even reuse macro definitions across multiple templates by defining a generic macro template and including (parsing) that template into other templates that want to use those macros.... read more

Sociaal intranet verhoogt de effectiviteit van organisaties

Bijna elke organisatie heeft wel een website die wordt gebruikt als visitekaartje en nieuwskanaal voor de business. Ook een intranet is zeker bij grote organisaties redelijk standaard. Helaas wordt een intranet vaak hoofdzakelijk gebruikt voor het zenden van informatie. Dat is een gemiste kans, want door sociale mogelijkheden toe te voegen, kan de effectiviteit van een onderneming enorm vergroot worden.... read more

Websites zijn mobiele portalen tot je business

In e-commerce is de term 'responsive design' al een tijdje in zwang. De meeste online marketeers zijn er intussen van overtuigd dat de conversie van een webshop (ofwel: in welke mate een bezoek wordt afgesloten met een transactie) direct afhankelijk is van de mate waarin een webshop zich aanpast aan mobiele devices. Dit heeft grote gevolgen voor elk bedrijf dat potentiele klanten wil bereiken via zijn webplatform.... read more

UploadPortletRequest and file size limits

Uploading files into portlet is quite common request these days and Liferay offers several ways how to archive it. The simples way is to use plain HTML form upload and retrieve files on the server side using UploadPortletRequest. It does not need any JavaScript (if you don't want to), one however has to keep in mind that this approach has some limitations. One of these is the size of the file, which can be result into the file (its binary content) not being available on the server side.... read more

Classloading in Liferay

Libraries (or JAR-files if you will) exist in many different locations in your Liferay installation. Some reside in Tomcat's lib folder, others are included in the lib folder of Liferay's ROOT. And of course, there are the libraries that are included in your own portlets. It's no secret that Liferay performs some magic tricks to enable access to different classes in different contexts. This complexity is mostly abstracted away from developers, so you don't have to worry if class X is indeed available for you from within a portlet. However, there are some very specific particularities that you need to be aware of as a Liferay developer. Welcome to the wonderful world of classloading in Liferay!... read more

Configuring a Liferay cluster (and make it use unicast)

Introduction

Configuring a Liferay cluster is part experience and part black magic. There is some information that you can find online, there's some information you can only find out while working on it and then there are some things like how to configure ehcache to use unicast that you can only discover through blood, sweat and tears. This post will first describe how to set up a Liferay 6.1 cluster with Ehcache in multicast and in unicast mode.... read more

Here are some of the new chapters and sections for you to check out in the Developer's Guide:

Hot Deploy vs Auto Deploy

There has been a tremendous lack of understanding around what Liferay means by "hot deploy" and "auto deploy". Most people get the two concepts confused, believing them to be one and the same. In reality, Liferay has TWO completely separate and different concepts: hot and auto deploy (i.e. Hot Deploy != Auto Deploy).

 

Hot Deploy

Many of you are familiar with hot deployment in the context of JEE application servers. This basically means if an application artifact (WAR or EAR) file is present in a specifically configured directory, the application server (e.g. Tomcat, Weblogic, etc) will pick up that artifact, deploy it within the application server, and start the application. If you are not familiar with this concept, please consult your application server's documentation.... read more

Integrating with the Liferay 6.2 Calendar app

Hello to all! smiley

This is my first post on liferay.com, so let me introduce myself: my name is Andrea (yes, it's a male name in Italy!) and I'm a software engineer working in the R&D group at SMC Treviso.

In this post I'll talk about the new Calendar app which was shipped with Liferay 6.2, and especially how to integrate it with the world around... I'd like to share my experience on that, because we've seen this kind of integrations may be a "killer application" in intranet (e.g. B2E) solutions and scenarios such as sales force automation, etc.... read more

Recommendations for your portal-ext.properties

Hi guys, I would like to share some important recommendations for your  portal-ext.properties files.

 

First, you must remember the order for the overwrite properties. Liferay loads the values of the properties defined in the portal.properties file (inside the portal-impl.jar), next overwrite with the values of the properties in portal-ext.properties, then overwrites with the values of portal-setup-wizard.properties, and finally overwrite with the values in the database.... read more
