Introduction Wow, I've blogged about Liferay Objects a lot lately. Talked about them too. Also am working on developing materials for learn.liferay.com about Objects. But one thing I haven't seen is an introduction to objects suitable for long-time Liferay users or new Liferay users, so I thought I'd take time to write one (since my blog ideas well seems to be...

Introduction I was recently in a meeting reviewing some FreeMarker templates that were extracting web contents using a structure, parsing and processing the data, and rendering an output. Basically the implementation was kind of the classic or "legacy" way of doing specialized presentation of structured contents in Liferay. In this case they had a Carousel...

Introduction So I was recently working with a team that was completing an upgrade assessment for a client wanting to upgrade from 7.2 to 7.4. A big chunk of the work in upgrading the client was going to be taken upgrading the themes. The client had one primary theme which contained the common style rules, but they also had 8 "child" themes, based upon the primary,...

Introduction So I kind of have a "famous" blog post on Liferay Scheduled Tasks: https://liferay.dev/blogs/-/blogs/liferay-7-ce-liferay-dxp-scheduled-tasks. I say "famous" because it has been used by many folks to create scheduled tasks for Liferay 7, but it has also been the source of some bugs (i.e. undeploying from a cluster could cancel a job ...

This article explains how to deploy npm packages bundled with webpack that export and import stuff through the standard ECMAScript modules feature. This is a sequel of the Moving from AMD to Browser modules in Liferay DXP blog post, so it’s recommended reading that if you haven’t done so already. Why use webpack with ES modules?

Introduction So I'm going to be putting together a series of blogs on new things that are available in Liferay 7.4, but I realized after starting a blog on Objects that I need to take a step back and instead start with what Liferay calls DSLQuery... DSLQuery is really an acronym for Domain Specific Language Query, because the foundation is based upon using a domain ...

If you've ever repeatedly gone through a checklist, with programming knowledge: How often did you have to repeat the steps until you automated them? Or, without programming knowledge: How often did you repeat them until you wished for them to be automated? I'm working in Liferay's Sales Engineering team. And in this role, I constantly set up new servers and install demos - and I'd...

"There is nothing new under the sun" - King Solomon, Ecclesiastes 1 In one sense, this blog entry doesn't contain anything new. In another sense, since it brings pieces of prior entries together, I hope that it provides some new insight for portlet developers to overcome the "Unresolved requirement: Import-Package" deployment error. Reference Blog...

Introduction You may have seen my blog Setting Up JNDI in Liferay 7.4 which I posted to explain how to do a JNDI lookup. The code works, I assure you, but there's one group of developers that blog didn't serve: Spring Portlet Developers. Whether you are developing using PortletMVC4Spring and Spring 5, or you are developing using Spring Portlet MVC under an older ...

Introduction I've been working with a client to upgrade their Spring portlet wars to Liferay 7.4. And the update is kind of big as we're upgrading Spring, changing to PortletMVC4Spring (needed for Spring 5), ... They have a large number of Spring portlet wars, but in reviewing the code I noticed that each of the wars had duplicate Spring services defined into the Spring...

Introduction My friend and coworker Eric Chin recently posed a question on our internal slack channels asking if anyone had experience with Liferay's Batch mode and he was not finding enough supporting documentation on it.
