Paul Hinz forwarded us an old whitepaper and presentation from IBM back in 2009 that sought to debunk the "myth of free open source portals." The main idea was that open source portals might save you money on licensing but the savings would be outweighed by extra costs in development, upgrades and maintenance.  Just for fun I did a little research to see whether Liferay...

  Greetings Liferay Community!   Based on the positive feedback we received after the East Coast Symposium, we will again be offering the Portal Administrator Express training in conjunction with the West Coast Symposium in Anaheim, CA.  The training will be the day before the WCS at the same location.     ...

  I'm working on my Liferay West Coast Symposium presentation which is meant to discuss how game culture can help build and enhance social collaboration for organizations.     I use Foursquare, Google+, Facebook, Liferay, Spotify, Twitter, LinkedIn and Last.fm as the basis for my networks.  Each has pros and cons to their UX, but the...

Ok, so in the last post I talked about JSP Include Buffer. That post talked about how you'd override JSPs from Liferay's core in a maintainable way. Now I'd like to introduce you to a Liferay Theme feature, new in 6.1, that will grant you much more power when it comes to manipulating portal views from your theme using that plus this additional feature. From your theme you can...

There are plenty of times when you might want to alter the default views of the portal. I'm not going to go into the why since that is hugely subjective. What I do want to show is the how you can do this in the most maintainable way possible. The largest concern with core JSP modification in projects is of course maintainability. JSPs have no "extensability" feature of their own...

Hello Liferay Community! I'll be running an upgrade workshop during WCS 2011 in Anaheim, CA. During that workshop, I'll be upgrading a Liferay 5.2.3 installation to Liferay 6.1 CE. I have data that I can use, but what fun is that?! I would like to upgrade one community members 5.2.3 installation to 6.1 CE for this. So here is my plan, if you all send me links to a zip of your...

Episode 1 of Liferay Radio is out. I'm speaking with James Falkner, Liferay's community manager. We spoke about these Topics (and probably more):           The community homepage on liferay.org liferay (the company) looks at more than just the bottom line (e.g.liferay foundation, though we didn't talk about this) geographical...

Context Path of portal can be changed by following the steps(eg. root-->portal): 1. Add portal.ctx=/portal to portal-ext.properties file(create a new if it does not exist by you yet). 2. Rename the "ROOT" webapp folder to "portal". 3. Locate the context configuration file "ROOT.xml" under <installation-path-of-your-apache-tomcat>\conf\Catalina\localhost and rename it to...

Let me introduce myself as the one who wants to be the resident german accent in your ears. After a long time of "just intending" I finally went ahead and started recording a podcast about Liferay - the project, the product, the people and the company. Episode 0, a brief introduction with the intent and some generic information is available for manual download. It's only 4:12. ...

¡Muy buenas!   Esta vez no voy a escribir sobre liferay, ni siquiera sobre tecnología, sino sobre personas. Personas que como tú y como yo tienen sueños, proyectos, ilusiones...pero que han visto sus sueños truncados por una situación que les supera. Me refiero a la situación en el Cuerno de África.   ...

You may have noticed a new feature on our community homepage, http://liferay.org - the Recent Activity Map is a dynamic Google Map that displays activities from our community, as they happen.  The map itself is a standard Google Map - and therefore, you can scroll around (using the hand tool), zoom in and out, and use the standard keyboard shortcuts (e.g. arrow keys, +/- keys). ...

Currently, our lib/development folder contains a lot of jars that are actually not used in development. Significant number (or, better, significant amount) is used for tests. Among these is selenium-server.jar, a huge jar that contains also classes from many other used frameworks (bcel, commons.*,  bouncycastle, json…). So what is the problem with this? If you use IntelliJ...

Shortcut: If you "just" want to know how to make different distinct sites (read: communities or organizations) appear as just one site, continue below the reasoning. Problem space Permissions are a sensitive area in any application. Quite often requirement documents can give the impression that it's more important what an application must not allow than the actual value...

Recently I was asked how to do this! Well, it's rather simple (providing you understand the limitations of accessing portlets without permission, and portlets that are not allowed to be loaded dynamically; a.k.a. add-default-resource, and so on). Here goes! First I created a simple web content structure/type with the following definition: <root>    ...

If you have a Maven repository running under https with a self-signed certificate, then building a Maven project can report the following error: Error transferring file: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target There was an Oracle...

We all know that Liferay is a great social content and collaboration platform, which is why we at Liferay use it to implement our liferay.com website.  There are tons of interesting potential statistics to glean from this, to introspect into our community a bit more than the standard "50,000 registered users, 170,000 forum posts" kinds of stats that often find their way into...

The rules are simple: Submit your idea, talk or presentation to get a slot - You get the stage for max. 7 minutes, then the next presenter will take over. It's...

Hi all, it's time for another installment of your linky-linky Community Roundup!  It's been quite busy in the community and at Liferay.  Community activity is buzzing and we are gearing up for various Fall events and activities, starting off with our annual West Coast Symposium in California, where there will be several key announcements, including the unveiling of...

Who has not ever had to fight with complex SQL queries and PreparedStatements? And, what about the ? symbol when enabling the sql log? Last week I had to write a big migration process in order to complete a refactor and I have done some little hacking in order to use the p6spy driver when running a migration process from command line. This driver will resolve the values for the...
