Just a quick one this morning... So I'm working on a project for 7.1. With my new love of the target platform, I decide I'm going to enable the 7.1 target platform for my DXP project. Everything seems to work fine until I deploy the portlet jar. That's when I get the following during deployment: 2020-02-01 08:40:06.324 ERROR...

Introduction So I get finished which the previous blog, Visiting DynamicQuery, and I shared it with my team. I'm always kind of happy when I get a new blog post done, so I share it with everyone I can think of. The first comment I got was from my friend and teammate, Shane Merriss: Hey Dave, thanks for the blog post, I’ll be able to share it with my client since we use it in a...

Introduction If you've used any Liferay entities or ServiceBuilder custom entities, you've likely run into a situation where you've needed to perform a custom query to get a set of results that are outside of what the normal methods provide. So you've had to use a DynamicQuery in order to make that happen. Or perhaps you've needed to perform batch operations on entities and...

One thing I sometimes see is using a given Liferay feature the wrong way in order to do something. Take delivering content to the right users. Liferay actually has a bunch of ways to accomplish this kind of thing. First we have taxonomy. Using vocabularies, categories and tags, you can apply taxonomy to your assets and then, through an asset publisher or search filter, for...

I did an informal poll on the Liferay community Slack channel recently: I was actually kind of surprised by the majority of votes for the "What is the target platform?" option. So, inspired by the results of the poll, I'm going to answer the question, What is the Target Platform? The Target Platform's Roots So the phrase, "Target Platform", is really a Liferay-only name...

As we near the first GA of 7.3, one change we've managed to make was to migrate off Soy + Metal.js and fully onto React.js. The story reminded me of how far our frontend infrastructure has evolved in the past fifteen years that I’ve been a part of Liferay. While this was initially going to be a longer post, due to some user error on my part, I have decided to split this into two posts....

Classic Liferay Localization Handling Any developer who has been around for awhile will have some knowledge of how Liferay handled localization for the entities... In your service.xml file where you normally just have a column type of String, you would also have an additional attribute set, localized="true". With this addition, your model classes getters and setters change...

So I've been seeing this a lot recently, so I thought I'd do a quick blog about it... With web contents, we can build structures to provide an organized chunk of data, and then we can define a template to render the HTML fragment for that structure. Since the template language of choice is FreeMarker, and since in FreeMarker we have practically the entire Liferay API (and...

Docker Official images can be found on Dockerhub and can be used for deployments on any system that is running Docker. For more information on configuration options for the image see the overview page. To get started with docker run the following: docker run -it -p 8080:8080 liferay/portal:7.2.1-ga2 Download You can find the 7.2 release on the download page.  If you...

Liferay 7.2 GA2 brings us many awesome new features but I'm particularly proud of one: GraphQL support. Starting today you can build dynamic JS applications with your preferred framework (which is the one trending today?) and leverage the powerful GraphQL queries to fill the entire screen with one request. In 7.2 we introduced the new breed of Headless APIs to help you serve...

Recently when I was working on my custom Headless API blog series, I ran into a bit of trouble with my Service Builder-based persistence tier. My SB code was done and working, and I was adding methods to my CLI tool to test all of the Headless methods. I had the list working, I could add, update and patch Vitamins, and I just finished the delete method testing and I was on cloud...

Introduction I've recently started working on a React SPA to take advantage of the Liferay Headless APIs. I was working through all of my implementation details and was finally ready to start making API calls, but I needed to figure out how to handle authenticated requests. I reached the following point in the documentation,...

If you’ve spent time rummaging around Liferay’s search and indexing documentation provided here, you’ll find a lot of details about document contributors, index writers, search registrars, etc. The part that might be missing is what all of these things actually do, why they are important, and why you actually want to go down the road of supporting indexing and search for your custom...

Introduction Welcome back to my series on using Liferay's REST Builder tool to generate your own Headless APIs! In part 1 of the series, we created a new project and modules, and we started to create the OpenAPI Yaml file defining our headless services by specifying the Reusable Components section. In part 2 of the series, we completed the OpenAPI Yaml file by adding in...

Just a quick post today... So I've been using the Target Platform like all the time now. I don't want to have to worry about versions, especially those Liferay modules that change version numbers on every fix pack... However, I've found that sometimes the version numbers just aren't there. But often I only find this out after I've stripped out the version and tried a build. My...

Introduction In part 1 of this series, we started a project to leverage Liferay's new REST Builder tool for generating Headless APIs. We defined the Reusable Components section, the section where we define our request and response objects, namely the Vitamin component and a copy of Liferay's Creator component. In part 2 of the series, we finished the OpenAPI Yaml file by defining...

Introduction In part 1 of this series, we started a project to build our own custom Headless APIs using Liferay's REST Builder tool. The project was started, four modules were created and I presented the Meta and Reusable Components sections from my OpenAPI Yaml file. We're going to pick up where we left off and finish presenting the Paths (endpoints) section and then start...

Introduction So recently I have been working with Liferay's new Headless APIs... I have a nice React-based SPA leveraging the new headless-delivery and headless-user-admin modules. I'm going to release everything eventually, but some parts just aren't ready yet. The first part is ready, though: using the new REST Builder tool to create your own Headless APIs. I know what...

Recently I was one of many trying to help a coworker figure out why a Liferay OOTB feature was failing... We had odd stack traces, null object references when OSGi never should have allowed a null to begin with, and nothing we tried would fix the problem. Eventually we found that, for some reason, two different versions of a Liferay bundle had been deployed into the environment....

So the last couple of days I've been working on a new React Headless app that I'm going to be sharing soon, but for various reasons I've had to refer to the /api/jsonws page to check out the classic APIs there that are still available. Just as a bit of background, I have an awesome 27" iMac that I do all of my development on. I love it so much that I purchased an additional Apple...
