The main purpose of this release is give you a sneak peak of what’s coming in 7.2 and to get an early start on testing our packaging process. It is by no means feature complete and hasn’t been tested for quality. The Liferay 7.2 Community Beta Program is scheduled to start with the release of 7.2 Alpha 1 in the coming weeks. 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...

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...

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...

I’m happy to announce the release of the first beta for the new set of Liferay REST APIs. But before going into details, for those of you who might not be aware of this project, I’d like to give you some context. Our vision Over the last year and a half, we have been working on a new set of REST APIs for Liferay following industries best practices. The goal of these APIs is to...

Background Last fall we reintroduced the option to use clustering in Liferay 7.0 by compiling a series of modules manually and including them in your project. We received a lot of feedback that this was a very cumbersome process and didn’t really provide the benefits we intended in bringing back clustering.   Enable Clustering Beginning with Liferay Portal 7.1 CE...

Update: This has been moved to January 11, 2019. Reason for the changes The vulnerabilities in TLS 1.0 (and SSL protocols) include POODLE and DROWN. Due to these security risks, Liferay decided to disable TLS 1.0, as many other companies have done. Moving to TLS 1.1 and higher will allow users to keep communications between Liferay and Liferay.com secure. What TLS...

So perusing the web, you'll notice there's a couple of resources out there explaining how to override the default favicon in Liferay. Of course, the standard way is to add it to /images folder of your theme and apply the theme to the site. As long as you got your path right and it's the default name, "favicon.ico," it should work just fine.  While this satisfies most use...

So we've all seen those @Reference annotations scattered throughout the Liferay code, and it can almost seem like those references are not changeable. In fact, this is not really true at all. The OSGi Configuration Admin service can be used to change the reference binding without touching the code. Let's take a look at a contrived example from...

Introduction When developing JSP-based portlets for OSGi deployment, and even when doing JSP fragment bundle overrides, it is often necessary to get service references in the JSP pages. But OSGi @Reference won't work in the JSP files, so we need ways to expose the services so they can be accessed in the JSPs... Retrieving Services in the JSP So we're going to work this a...

Introduction The official Liferay deployment docs are available here: https://dev.liferay.com/discover/deployment They make it easy for folks new to Liferay to get the system up and running and work through all of the necessary configuration. But it is not the process followed by professionals. I wanted to share the process I use that it might provide an alternative set of instructions...

Introduction A client recently was moving off of Google Search Appliance (GSA) on to Liferay and Elasticsearch. One key aspect of GSA that they relied on though, was KeyMatch. What is KeyMatch? Well, in GSA an administrator can define a list of specific keywords and assign content to them. When a user performs a search that includes one of the specific keywords, the associated...

Introduction So often when discussing how to deal with dependencies, we're often looking for ways to package our third party jars into our custom modules. There's good reason to do this. It ensures that our modules get a version of a third party jar that we've tested with. It also excludes ambiguity over where the dependency will come from, whether it is deployed and available or...

As some of you may have already discovered, 7.1 GA2 was released as a 7zip bundle instead of the typical zip bundle. This probably caused a ton of issues. Even our own Dev Tools are not yet equipped to handle 7z files since all the events took up our time. I will provide you with the reasons why we had to make this move and hopefully, everyone will come to the conclusion that this...

Mitigating RichFaces 4.5.17.Final EOL Vulnerabilities If you are using RichFaces, you should be aware that Code White has discovered some remote code execution vulnerabilities in the component library. Unfortunately, since RichFaces has reached end-of-life status, these vulnerabilities will not be fixed. Thankfully there two easy options to mitigate these vulnerabilities: ...

Helping my colleague Sergio Sanchez with his GDPR talk in the past Spanish Symposium, I came across a hidden gem in Liferay 7.1. It turns out you can integrate custom Service Builder entities with Liferay’s GDPR framework (UAD), to enable anonymization of personal data in your own entities. I didn’t know anything about this feature, but it’s really easy to use and works like a...

In the previous posts, we talked about what we were going to do, how we were going to do it, and which tools we were going to use. We introduced you the Liferay Screens’s screenlets and the reason why we were going to use them. Well, it’s time to explain to you how we developed this application and how a junior developer, with only one year of experience in the mobile world and...

Previously, we talked about how market is really fragmented right now because there isn’t any popular hybrid framework. We kept an eye on some of the most popular frameworks like React Native, Nativescript, Ionic2 and Xamarin. We did a prototype with Nativescript and it worked fine but we think that the use of native libraries with this technology isn’t mature enough. If you...
