Introduction I was recently polling my coworkers looking for new blog ideas, and Filipe Melo asked about Websockets. I haven't seen any other documentation or blogs about building Websocket solutions for Liferay, so I figured this would be an interesting challenge. Websockets was introduced to provide a full duplex and realtime client/server communication path between remote clients and your...

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. Although I hadn't yet worked with Liferay Batch, I kind of took it as a challenge to not only give it a try, but more importantly to document it in a new blog post, so here...

The following versions of PortletMVC4Spring were released on January 5, 2022 AD: Version Description   5.3.1 For use with Spring Framework 5.3.x (tested with 5.3.12) Release Notes 5.2.2 For use with Spring Framework 5.2.x (tested with 5.2.18.RELEASE) Release Notes 5.1.3 For use with Spring Framework 5.1.x (tested with 5.1.20.RELEASE)...

Introduction I posted two blog posts this week, and each of them had a particular drawback - lack of cluster coordination. The first blog post on cluster-enabled upgrade processes introduced using an @Reference dependency upon a specific Release version, the idea being that the component shouldn't start unless that version was available. When the upgrade process would run on the cluster...

Just a quick one... I've just updated my Log Persister project for Liferay 7.3. You can find it under the 7.3 branch: https://github.com/dnebing/log-persist/tree/7.3 For those that aren't aware, I introduced the Log Persister here: https://liferay.dev/blogs/-/blogs/liferay-7-dxp-making-logging-changes-persistent Normally Liferay does not persist logging. If you make any changes in...

I recently was helping a client with an upgrade process and that had run into a little problem... A few of the model hints were not updated on some of the columns in their Service Builder services and, as we all know, Service Builder will not ensure the columns are changed in a production environment (well, actually any environment where the schema.module.build.auto.upgrade property is not set...

A really quick post to share something important with you React + Clay developers out there... A recent update to Clay had a breaking internal change. If after deploying your React portlet and you try to place it on the page and you get errors in the JS console like: liferay-amd-loader | Errors returned from server for require( ["my-module@1.0.0"] ): "Missing dependency...

Introduction A client asked me to build a React portlet for them and I was like, "Oh Yeah!" I mean, it's been a while since I built a React portlet and tooling has really changed a lot since then, so I was really looking forward to this new task. So without further ado, I'm just going to dive right in... Creating the Module Okay, so this is still Liferay and still OSGi, so we're going to be...

Each year at about this time I try to post the download stats for the Liferay Faces project. I am pleased to report that downloads for the Liferay Faces project hit another all time high back in September of 2020, and held fairly steady until January of this year (2021). Downloads seem to take a dip after the holidays, so perhaps that's why we saw a drop-off in February. Since then,...

If you’ve ever looked at a Liferay workflow implementation and its scripts, you might have seen workflowContext being referenced in the scripts that are executed in the individual tasks and states. I’ve recently had my first scripting contact with Workflow, and wanted to look at this context, and what it can do for me. Digging a bit, you’ll find out that workflowContext is a Map<String,...

Introduction One of the great advantages I have being known in the community is really the opportunity to meet, talk and work with talented developers and teams. Recently the team at ACSoftware announced in the Liferay Community Slack they were working on a new Liferay development tool, and I was fortunate enough to work with them on evaluation and testing. As it is just released, I...

About a year ago, Liferay introduced a new program that I have been actively participating in, Liferay Developer Services. But what is this program? Liferay Support When you are a Liferay DXP customer, you automatically get access to Liferay Support as part of the Subscription Services. Support is staffed by a great bunch of people that want to help clients resolve product-level issues....

Sometimes there are several ways to achieve a goal - and this is a story about one of those times, and one of those different paths to achieve a goal. Recently, in a conversation, I came across two different ways to solve the same problem: One is way more graphical than the other, and both have their advantages, disadvantages and limitations: How to edit next month's special...

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...

Let me say that again: Content Creation is Not a Development Activity! Pretty strong statement, but for for those considering Liferay as a platform it's really an important concept, one that lives in the core of Liferay. Note: This is really a different kind of blog post for me. I prefer to keep things technical and discuss practical solutions to ...
