The one thing I never understood was why the UI behind the /api/jsonws is publicly viewable. I mean, there's lots of arguments for it to be secured: Exposing all of your web service APIs exposes attack vectors to hackers. Security by obscurity is often one of the best and easiest form of security that you can have1. Just because users may have permission to do...

Every now and then, there comes a time in a CMS developer's life when the sin of taking default settings for granted takes its toll.    There. I phrased that carefully so it would make a list of quotable quotes some day. Now, let me get to it.   Like many developers out there, I am a huge fan of content-driven...

Introduction Today I ran into someone having issues with ServiceBuilder and the creation of UpgradeProcess implementations. The doco is a little bit confusing, so I thought I'd do a quick blog post sharing how the pieces fit... Normal UpgradeProcess Implementations As a reminder, you register UpgradeProcess implementations to support upgrading from, say, 1.0.0 to 2.0.0,...

Historically there have been a number of extension points in Liferay that enable developers to hook into portal events and add their own custom/additional behaviour. In Liferay DXP this is still the case and the list below shows when certain events are fired and in which order. You’ll notice that a number of events are mentioned multiple times because they’re shown in the context of a...

In this tutorial, I am going to talk about how to utilize promise object to access web service in Liferay DXP.   Before we get into more detail, please take a note that the version Liferay I am using is Liferay DXP DE-15, since there's big soy development experience improvement in this patch.   Previously...

Introduction When it comes to Liferay performance tuning, there is one golden rule: The more you offload from the application server, the better your performance will be. This applies to all aspects of Liferay. Using Solr/Elastic is always better than using the embedded Lucene. While PDFBox works, you get better performance by offloading that work to ImageMagick...

So I have a blog I created a long time ago dealing w/ Liferay and SSL. The foundation of that blog post was my Fronting Liferay Tomcat with Apache HTTPd post and added terminating SSL at HTTPd and configuring the Liferay instance running under Tomcat to use HTTPS for all of the communication. If you tear into the second post, you'll find that I was using the AJP connector to...

In case you aren't aware, Liferay 7 CE and Liferay DXP default to using Hikari CP for the connection pools. Why?  Well here's a pretty good reason: Hikari just kicks the pants of any other connection pool implementation. So Liferay is using Hikari CP, and you should too. I know what you're thinking.  It's something along the lines of: But Dave, we're...

Since Liferay DXP support Lexicon, I am going to show you how to utilize Lexicon and Bootstrap to create a true mobile responsive carousel in web content. It's remarkably easy with Lexicon and Bootstrap to create...

For the last few months as I've been working with Liferay 7 CE / Liferay DXP, I've been a little stymied trying to manage the complexities of the new OSGi universe. In Liferay 6.x, for example, an OOTB demo setup of Liferay comes with like 5 or 6 war files.  And when the portal starts up, they all start up. But with Liferay 7 CE and Liferay DXP, there are a lot of bundles...

  Mobile First with Liferay Screens – part 4 Webinar: Mobile Strategy: Optimizing for the Connected Customer   Mobile apps have become an integral part of our communication with customers and personnel. After all, the best way of reaching people is on the devices they use the most: the smartphone and the tablet. With Liferay Screens, a mobile app is also...

For those of you deploying Liferay DXP to WebLogic, you will need to add an override property to your portal-ext.properties file to allow the WebLogic JAXB implementation to peer inside the OSGi environment to create proxy instances. I know, it's a mouthful, but it's all pretty darn technical. You'll know if you need this if you start seeing exceptions like: ...

Introduction So I've been working on some new Blade sample projects, and one of those is the Spring MVC portlet example. As pointed to in the Liferay documentation for Spring MVC portlets, these guys need to be built as war files, and the Liferay Workspace will actually help you get this work done. I'm going to share things that I learned while creating the sample which has...

Okay, this is probably going to be one of my shortest blog posts, but it's important. Some releases of Liferay have code to "infer" a portlet name if it is not specified in the component properties.  This actually conflicts with other pieces of code that also try to "infer" what the portlet name is. The problem is that they sometimes have different requirements; in one...

  Every other year we have a company retreat where people from all over the world travel to California for a series of meetings and team building activities.   This is a very unique opportunity for us and we're always thinking about ways to maximize it. This time we decided to organize another internal hackathon. That way...
