Here are, off the top of my head, the 5 typical responses, from my point of view, from the past months of running around the world introducing Oracle JET.

Oracle as an Agent of Social Change

Together with my colleague JB Brock I've spent the past week in South Africa. Last year, with Andrejus Baranovskis from Oracle partner Red Samurai Consulting, I did something similar—introducing Oracle's new modern vision on application development and user interface design to a range of Oracle partners and customers, including to Oracle staff in the the local Oracle offices, too.  A pic of a few of them is below, taken in Cape Town, Johannesburg, and Pretoria. Just like the...

From ojNavigationList to ojTrain

Sometime ago I showed how to replace ojNavigationList in the 'navdrawer' template with ojButtons. Let's now do something different and replace ojNavigationList with ojTrain: The router is integrated into it, so that everything works as before, except that now you have a step sequence. In 'main.js', add a reference in the 'require' block to 'ojs/ojtrain'. In 'appController.js', add the following, which is the array that ojTrain will use: self.stepArray = ...

Beyond Mobile App vs. Mobile Browser

The continual discussion of whether to create a native/hybrid mobile app or to create an app accessed via the browser, has two recent alternatives. The starting point is to recognize that most people use about 5 apps on their mobile device and ignore the other 30 or so that are there by default. Most people have no clue about which apps are available and don't go searching for them randomly in an app store. Instead, they go to their browser on their mobile phone, access the...

Software Adoption Surveys: From Quantity To Quality!

In a democracy, everyone is equal. One person, one vote, and all votes are equal since all people are equal. Erroneously, that approach is applied to software adoption surveys too. Anyone at all can respond to a survey and can indicate that they use software product X, Y, or Z. However, what if I am a student paddling in the shallow waters of software development, with the likelihood that I'll abandon it before I graduate, while you are a senior Java architect creating mission...

JShell Integration in NetBeans IDE

I've blogged about the integration of the Java 9 JShell in NetBeans IDE before, here and here. In the latest daily builds, assuming you're running the daily build on top of Java 9, you'll see the top part of the JShell looks the way you'd like it, i.e., there's a nice code fold and the first statement is numbered 1, rather than 9 as it was initially, as can can be seen in the previous blog entries.

Running NetBeans IDE 9 Development Build on JDK 9 EA Build 162

For the adventurous, interesting times ahead since you're able to try out the NetBeans IDE 9 development build on top of JDK 9 EA, in my case, Build 162. When you configure that in your 'etc/netbeans.conf' file, the first thing you see on start up is this error, which appears to be related to the Darcula plugin that I'm using.

Getting Started with Oracle JET Composite Components

I worked with JB Brock yesterday on setting up and using Oracle JET's new Composite Component Architecture. The aim of it all is to have reusable components that enable you to define your own HTML elements, like this, for example: <!-- ko foreach: employees --><demo-card class="oj-flex-item" name="{{name}}" avatar="{{avatar}}" work-title="{{title}}" work-number="{{work}}" email="{{email}}" ...

Finegrained JShell Integration in NetBeans IDE

In addition to the generic JShell integration in NetBeans, discussed yesterday, there's more finegrained support enabling project-specific JShell snippets to be run. That means, depending on how you organize your life, no "build" will be needed anymore when you try out your code. Just hack a snippet together, run it in JShell, when/if it works, move it to your project.Each project, whether Maven-based or Ant-based, will have an "Execute Java Shell" menu item, which is shown...

Learning Java with JShell in NetBeans IDE

Let's use JShell to learn about Paths and Files and Streams... here we go... this seems to work, since the Output window prints out the content of my file, which has two lines "hello" and "world": Sweet documentation explains everything: Next, let's put that useful code snippet to some use... i.e., we'll move it into a new Java source file in my application: And there it is, all the verbosity/expressiveness of Java wrapped around our little snippet: Hmmm. This will be pretty...

Tip for JavaOne Speakers with NetBeans IDE

Quite a few speakers at JavaOne 2016 will be using NetBeans IDE for demos during their sessions. Excellent. Less excellent is the yelling that will befall you when your audience wants your font to be bigger. So.

From Oracle JET Web to Hybrid

A 'web' project scaffolded using Oracle JET 2.1.0 can be extended with 'hybrid' features. You can then build both web or hybrid app from the same sources. To add the 'hybrid' capabilities to a web project, use the oraclejet:add-hybrid command in the application directory: yo oraclejet:add-hybrid --platforms=android|ios|windows --appid=com.my.app --appname="My Hybrid App" The --appid, --appid, and --platforms options take the same values as the yo oraclejet:hybrid generator. The...

The Mechanics of Theming Oracle JET Applications

We have a requirement to have different themes for our Oracle JET application, "business" and "pleasure". The first will have images of serious business suits, the second will have party hats; the first will have grey/blue fonts and colors, the second will be polka dots or something. You want the themes to be able to be swapped in and out at build time. OK, that's the scenario. 1. Create the application. Let's imagine we start like this: yo oraclejet myapp --template=basic OK,...

Patterns for Global Settings in Oracle JET Applications

While following the Oracle JET MOOC, especially when dealing with topics that relate to routing and navigation, you'll find a few contrasts between the MOOC and your own Oracle JET applications. Though not true for all the application templates, you'll notice one or two new files, one or both of 'appController.js' and 'navigation.js': Now notice how clean your 'require' block is, in 'main.js': require(['ojs/ojcore', 'knockout', 'appController', 'ojs/ojknockout',...

Avoiding Hiccups in Building Oracle JET Applications

When using NetBeans IDE to work on an Oracle JET project installed using the Yeoman generator on the command line, the files in the "src" folder are incomplete without the build command being run. Of course, you can just enable the Grunt build task and that solves that issue. Just right-click on the project and choose Build: The first time you do this, you'll be prompted as follows: Say Yes and you'll be here (your version of the below may be different to mine since I'm using...

Adding Some Color to the RebelLabs Developer Productivity Report 2016

I used to have a very nice colleague who would never disagree with me. He'd never say 'I disagree with you'. Instead, he'd always say, 'let me add some color to that', after which he'd proceed to, essentially, disagree with me. :-) [I miss you, Ashwin!] But it was a nice experience. He wasn't disagreeing, he was adding color. In that light I'd like to look at an aspect of the RebelLabs Developer Productivity Report 2016. It wasn't released very long ago and has the following...

Most Unique Feature of NetBeans IDE!

Also, there is documentation for the OAuth helper library in the...
