Introduction In the earlier days of Liferay, many administrators missed the warning about not using HSQLDB in production. By default, Liferay is configured to use HSQLDB so you can spin up a Liferay instance for development or testing or whatever, but HSQLDB was never to be used in production because it is not a production-ready database. It's easy to set Liferay up to use a...

Liferay Faces Roadmap for Liferay Portal 7.2 Support (2019) For Liferay 7.2 support we have three major goals: 1. Support deployment of thin JSF WARs. Liferay Faces has always required that developers embed the JSF implementation (Mojarra), all Liferay Faces JARs, and (optionally) CDI inside their WAR’s WEB-INF/lib folder. However, in Liferay 7.2 CDI dependencies will be...

Similar to 7.1, the 7.2 beta program will be divided into...

Introduction For folks that know me, they know one of my favorite soapbox rants is on HTTP and/or Portlet session storage. Recently my friend Kyle Stiemann wrote a blog about Session Storage in Liferay, and he reached out to me to proof the blog post before it was published. While it was really well written and informative, I must admit I didn't want it published. Providing a...

For a recent project, we developed an Angular application that uses Liferay DXP as the back end. In this Angular application we regularly make requests into the Portal back end for User information, Journal Articles, ... Mostly this works great as we have defined several custom REST end points in DXP from which we can make use of the Liferay services and other nifty Liferay stuff. ...

Introduction I have helped many companies and organizations install Liferay (5, 6 and now 7/DXP), but often times they will stop there. I mean, once the app servers are up and serving traffic correctly, aspects like the log file(s) are ignored. Well, at least as long as everything is operating smoothly; when something has gone wrong, the log file(s) is (are) one of the first places...

Before I answer this question, consider: What are you actually trying to accomplish? Are you sure that you need share session data to fulfill your goal? Can you use another (better) method to share data between several portlets across several requests? David Nebinger, Liferay expert and prolific community member, has said that "Session Storage is...

Since Liferay 7.1, pages management has been completely redesigned. Now the navigation tree presented to end-users are controlled by the new Navigation Menus rather than the position of pages in the pages administration screen (now using the Miller columns visualization system). Unfortunately, by the time these lines are written (i.e. with Liferay 7.1 GA2), the position of a page...

While trying to give your users the best experience ever you always try to keep things simple. In the past I have filled in many forms and many times with the same data and many times at the same site. Why? As a simple example I took a free 'zipcode to address' service in the Netherlands and used this to show how easy this can be done. And this is what it looks like. Todo...
