Introduction Several months ago I wrote an article about Site Initializers (read if you missed it 😉). It describes how to setup content using Bundle Site Initializer. And it also highlights (in article itself and in comments) that the main issue with Site Initializers was missing "update" support: if any changes to content required - site should be re-created from the...

Since Liferay introduced Stylebooks, the Best Practice for your installation has changed, to no longer deploy your own theme, but rather use a stylebook and change it to adhere to your Corporate Identity. Using someone else's CSS classes is quite a task - in fact, even my own CSS classes from more than 1 day ago are hard to remember: Where exactly is the hyphen? Was the prefix...

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 ...

Another short one today, this one is due to something shared with me by my good friend Olaf Kock... It starts with a question - do you like waffles? Or, more specifically, do you like the Liferay Waffle Menu? It starts with the little waffle icon:  And from there, you get to your Applications menu: Or even your Control Panel: I do like the waffle menu,...

Liferay Objects can generate service layers by simply declaring schema in the Liferay control panel. Liferay makes the Object's content accessible via headless APIs as well. On Notifications with Liferay Objects, I've already written one blog post. I'll go over the fundamentals of objects, mappings, and Layouts in greater depth.     Create Objects Go to Liferay's...

Another quick one today... So when you start your brand spanking new Liferay environment, you will automatically get your test@liferay.com administrator account (or test@<your company email here> if you've set up the company.default.web.id and/or company.default.virtual.host.mail.domain property keys before first launch, or <your admin>@<your company...

Low code and no code development are handy for developing a website without a technical background. Liferay came with the Object concept, which is able to generate the persistence and service layers by just defining the required fields from the liferay control panel. In this blog, here are some essential points from the objects.   Notification for an object entry ...

So just a quick blog post today... I was working with Support where they were trying to help a client that had a failed U64 bundle upgrade in Production and we were trying to understand what the failure was and help the client complete the upgrade. Then my friend Christopher Lui happened to mention: the odd thing is that this customer upgraded their Dev environment...

Introduction Recently there have been a bunch of questions lately in Slack, in Ask, and even in Liferay Support tickets complaining about the time it takes to log into Liferay and what can be done to improve performance, specifically targeting the hash algorithms... TL;DR - Liferay has increased the rounds on the PBKDF2 hash which is detrimental to your login...

Just a quick one today... A community member reported getting an exception during module deployment: INFO [com.liferay.portal.kernel.deploy.auto.AutoDeployScanner][AutoDeployDir:238] Processing com.liferay.report.jar ERROR [fileinstall-directory-watcher][DirectoryWatcher:1195] Unable to start bundle: ...

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 Liferay development has been changing throughout the years with its different versions. With 6.x we had WAR portlets. 7.0 came along and with it OSGi modules were the norm. And now, 7.4 has brought something completely new: Remote Apps. You can check this other blog and the official documentation for a thorough explanation about Remote Apps.   So, what...

Introducción El desarrollo en Liferay ha ido cambiando a lo largo de los años con sus distintas versiones. Con las versiones 6.x teníamos los portlets de tipo WAR. Cuando llegó la versión 7.0 los módulos OSGi pasaron a ser el estándar. Y ahora, 7.4 nos ha traído algo totalmente nuevo: Remote APPs. Si queréis una explicación más detallada sobre Remote Apps podéis echar un...

Introduction So my friend Thiago Moreira posted the following (slightly edited) message to our internal Slack: Hey, so I've built a module for 7.4 GA5, but when it is deployed to 7.4 GA16, I get a bunch of "unresolved requirement" exceptions and the module won't be available. Is there something I need to set so my module will work on both GA5 and...

Just a quick one today... In previous versions of Liferay, if you were browsing a site as a guest but wanted to access a private page or a private site, Liferay would automagically show you the login form so you could authenticate before accessing the page or site. This has been changed in 7.4. It was determined that just by showing the login form, Liferay was leaking the fact that the page...

Introduction Recently I was asked how to implement MDC and/or NDC in Liferay 7.4, and since I thought it might be interesting to a wider audience, I'm going to blog about it here. Background In a multithreaded, multiuser environment such as in a web application like Liferay, different threads in the container will be handling different requests, but likely each request is doing something...

Introduction In November of 2018, I authored a blog, Boosting Search. In that blog, I showed how to boost search results for tag matches in an effort to provide some alternative to GSA's KeyMatch support. A lot has changed in Liferay since that blog was posted, and it turns out there are much easier ways now in DXP 7.4 that won't require any code at all... Results Ranking In discussing the...

Overview In this blog I'll explain how to implement a custom Headless API module, configure an OAuth2 authorization and consume the API.  We’ll implement the Headless API for “App manager” functionality with endpoints to get the list of apps, get app details, create/update/delete the app (“App” here is a model, describing some external application with the following...
