"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.

And the update is kind of big as we're upgrading Spring, changing to PortletMVC4Spring (needed for Spring 5), ...

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...

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...

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...

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.
