  An episode on the "Per" things: Performance and Permissions. I spoke to Preston Crary, who amazingly was not mad at me for losing an earlier recording. We're talking about these (and more) topics We open with the attention to detail that's required for working on performance tuning and some short conversation about this topic. Sadly, there's not often a single...

Everyone wants to see Liferay Portal in their native language, and version 7.1 will support up to 45 different languages. On the road to the release of Liferay 7.1 we are launching the Community Translation Team to drive the translation process. Read this post to find out why and how you can help to make Liferay Portal available in the languages you speak. Liferay Portal is used...

Introduction So originally I presented the blog post, Fronting Liferay Tomcat with Apache HTTPd daemon, but that post featured my partiality for using mod_jk to connect HTTPd and Tomcat. Personally I think it is much easier to do the JkMount and JkUnmount mappings to point to Tomcat, plus Liferay sees the original request so when it generates URLs, it can generate them...

A good friend of mine, Minhchau Dang, pointed out to me that I have frequently used OSGi version ranges in my blogs. I explained that I was concerned that I didn't want to bind to a specific version, I often wanted my code to work over a range of versions so I wouldn't have to go back and update my code. He pointed me at the...

Welcome to the Liferay 7.1 Community Beta Program!     During the Liferay 7.0 development cycle we launched the Community Expedition program.  With over 600 participants this was one of our largest and most successful community programs to date.  It is in large thanks to our awesome community who was...

Q-Have you ever wondered if you can customize your Elastic Search, so that on your searches in Liferay, not only the words you're searching for come up in the results but also synonyms of these words? A-Yes, you can! Below, I'll show you an example of how I did it (by customizing my indexes and mappings settings). Let's say that I have a web content article containing the word...

So the question comes up how to do Liferay upgrades. I'm not talking here about the technical details of how you upgrade one particular plugin to another type of plugin, what kinds of API changes have to be made, etc. Instead, I'm thinking more about the general process of how to upgrade, what choices you're presented with and what the ramifications are for making certain...

Tomcat 8.5 is an in-between version of Apache Tomcat 8.0 and 9.0. According to the Apache site, it contains some features in 9.0 that have been backported to 8.0. This version of Tomcat is currently in the "Supported" matrix of the Liferay DXP Compatibility Matrix, and of course, the question is: How do I set up Liferay CE/DE 7.0 with Tomcat 8.5? The short answer is: Exactly like...

So Jamie just announced the new Liferay 7.1 Community Beta Program here: https://community.liferay.com/news/liferay-7-1-community-beta-program/ I recommend everyone who has working code in Liferay 7.0 or Liferay DXP should join the 7.1 beta sooner rather than later. Why? Well, mostly because Liferay's engineering team is focused on the 7.1 release, so anything that you...

Introduction In recent times, containers are becoming more and more important in the software lifecycle management, whether we like it or not. The majority of  the leading software companies have already released a Docker version of their products, Microsoft did a huge work to adapt Windows kernel to Docker containers features, many Cloud services sell container-based...

Okay, in case it is not yet clear, Liferay 7 uses an OSGi container. I know what you're thinking: "Well, Duh..." The point is that OSGi is actually a standard and anything that works within OSGi will work within Liferay. You just need to understand the specs to make something of it. For example, I'd like to talk about OSGi Fragment Bundles. There's actually stuff in the...

I have been working on adding CKEditor plugins to the Alloy Editor in Liferay DXP and figured I would share what I found. Specifically I was trying to add the YouTube Plugin. There are some articles online at Liferay but they focus more on packaged or custom developed plugins. I got close streaming the files into the Dynamic-Include, but there is a better way (thanks to...

In the very beginning of every mobile app project, we can have to face a tough decision: should I go for a native approach to make the most of the device capabilities and optimize the user experience, or should I prefer a hybrid development to make progress faster even though the result may be not as good. And you have to choose either one or the other. A few...

I am very pleased to announce the first release of Adaptive Media available for Liferay 7 GA5 and Liferay DXP. Below you can find the links to download the app from Liferay Marketplace. Download Adaptive Media DXP Download Adaptive Media CE What is Adaptive Media? In case you are unfamiliar to Adaptive Media and you want to know more about how this powerful app can...

So I've been working a lot more with Angular 2+ recently (Angular 4 actually, but that is not so important) and wanted to share some of my findings for those of you whom are interested... Accessing the Liferay Javascript Object So TypeScript is sensitive to defined variables, classes, objects, etc.  Which is good when you want to make sure you are building complex apps,...

So, as a developer, I'm like usually whacking my whole runtime environment and starting over. Why? Well, regardless how much I try to keep it clean, cruft will find its way into the environment. I'm left with users I don't want, content I don't want, pages I'm not using any more, sites created to demo something I'm not demoing any more... So I'll throw out my data directory,...

At Liferay Symposium North America 2017, I had a discussion with a few of our customers on the hidden dangers of rolling back Liferay changes. There are multiple ongoing efforts to improve how we will handle the issue for the upcoming 7.1 release, such as LPS-76923. However, the 7.0 release is already affected, and DE-40 is fast approaching with another round of hidden dangers...

On October 6, 2017 my colleague Sebastiaan and I held a presentation at Liferay DevCon about a cool integration the COIN team made. We were looking for a fun and exciting Internet of Things integration in Liferay. After a fruitful brainstorm, we decided to use Philips Hue. Another couple of brainstorms later, we formed the actual idea. The setup was to create an imaginary...

Liferay has different types of pages. The default one is Layout - it’s standard, empty by default page, which is displayed in navigation menu. Portlets may be added to such page, themes and layouts may be also applied to this type of page. In most cases this page type is used. But there are different page types, here are they: Link to a Page of This Site -...

To make some custom class available inside a theme velocity template, you need to put it's instance into com.liferay.portal.kernel.util.WebKeys#VM_VARIABLES request attribute. And it will be populated to the velocity context automatically (in com.liferay.portal.velocity.VelocityTemplateContextHelper#prepare method), see: // Insert custom vm variables Map<String,...
