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...

And in this role, I constantly set up new servers and install demos - and I'd...

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,...

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...

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.

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...

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.

For example, cd themes/my-themenpm installgulp build However, Liferay has not documented ways to integrate the above to a Maven project pom.xml.
