There has been few queries in the Liferay forums w.r.t to support for WSRP (Webservices for Remote Portlets) in Liferay. Here is a summary and some links that point you to this integration effort.

In Liferay we have this cool new feature to run portlets as embedded widgets from any webpage anywhere. Tired of loosing you chat sessions on every page refresh??? No more!!! Well feast your eyes on Liferay Portls running as APPS on your desktop. Completely standalone, no shared memory, if one process crashes the others will not. Take a look at these babies.   ...

Previously, to customize a core portal JSP, you would have to use the ext environment. You can do it now in a plugin via our liferay-hook.xml file. Just specify a directory of where your custom JSPs are, and on deploy of that plugin (portlet, theme, hook, etc.), the core portal JSPs will be overwritten with what's in your plugin, and on undeploy, it'll be reverted back. When...

Some people might be wondering why I've been so scarce around here. The reason for this is that I and my team have been heads-down working on a couple of brand new training courses that we will soon be offering. We've just put the finishing touches on both courses, and I am excited about what's in store. First up is the new Portal Administration course. This is a two-day introductory...

Perhaps I'm dating myself, but when I entered college in 1988, the Computer Science department required me to buy a Mac II because it was the only personal computer of the day that ran a type of Unix. No, not Mac OS X silly, but A/UX. I never really used the Mac OS back then -- always did my projects under A/UX. Recently my buddy Ed Burns invited me to a "classic arcade game" exhibit...

UPDATE: 2019/01/11: Please refer to Kyle Stiemann's blog titled How can I share session data across portlets in Liferay? which discusses the various benefits and drawbacks of data sharing approaches that are now available. If you want to share data between portlets, a common way to do that is by storing data in the user's session. Liferay Portal has some nice features for...

The open-source software movement (also known as the free software movement) received a boost Wednesday from the federal appeals court in Washington, according to an article from the New York Times. The court ruled that “just because a software programmer gave his work away did not mean it could not be protected.” ...

We've made some enhancements to the search infrastructure of the portal recently. We abstracted out Lucene as a search engine, now people can build plugins that integrate with others search engines frameworks. For example, it's possible to replace Lucene with Solr, FAST and Google Search Appliance as long as a plugin is developed to interface with them. Currently the only plugin...

I've been being asked this a lot recently, so I'm going to blog it. Also a wiki on it.   5.1 To see a listing of available web services (v 5.1), you can go to the following URL with Liferay running locally: http://localhost:8080/tunnel-web/axis It will also give you access to the WSDL files. It looks like this: And now... Some Services ...

It has been a pleasure to work with all of you at Liferay. Being involved in free software projects for more than ten years, I have found that Liferay is a very...

Brian just wrote a great blog about the Meetup and I couldn't resist adding my usual philosophical shpiel. The Meetup this year was interesting because of how much it was a reflection of the social collaborative dynamic of companies and communities like Liferay. Liferay is a geographically distributed, heterogenous (employees, customers and community enthusiasts) group of people...

The idea is to let a person who posted a messsage expecting answer to vote on comments as the solutions. Once those information built-up, we could use them for construct a FAQ. The current implementation is using the MBMessageFlag table for the marker, because it was only used for marking the read status of a given message for users. This will not create needed step for upgrade. ...
