Spring Batch: Using JAXB And StaxEventItemWriter To Generate XML

Jonny Hackett Java, Spring Batch, Tutorial Leave a Comment

While working with a client recently, my team was given the task to retrieve the held securities and account data from the system and export it to XML with the goal of importing it into another external system. The solution involved building a Spring Batch job that would read a set held security data, export that to XML data, and deliver the file to the external vendor securely.

In this blog, I’ll be giving a tutorial on how to execute this solution. These requirements form the basis for the example we’ll use.

Placing React in Timeout with Material-UI

Peter Le Development Technologies, React, Tutorial Leave a Comment

As your application complexity increases, you may start thinking about implementing a session timeout in instances when there is no activity for a period of time. Whether you want a session timeout to increase your web app securities or to avoid unnecessary automatic API calls, it’s good to have some sort of idle check and log out built into your application.

Azure Web Apps in Docker Containers – Part 1

Joe Sciara Architecture, Azure, Cloud, Development Technologies, Docker, Tutorial Leave a Comment

So you want to host a web application on Azure with minimal overhead, but how is this done? Azure makes it possible by running an App Service using Docker containers. Setting up an App Service is simple and can be accomplished with a few steps.

In this blog, I’ll explain the steps necessary to generate a Docker image in Azure. Then, we will deploy a web application based on an image we generate. We host the application with the following steps:
1. Create a Container Registry
2. Build a Docker image
3. Create a Web App

Quick Look: java.util.stream Examples

Keith Shakib Development Technologies, Java Leave a Comment

Some of us take for granted the newer features in Java, but, being a software consultant, I get to be involved in projects that are sometimes constrained to older versions of Java. The features from Java 1.8 that I have enjoyed for a few years are brand new to others.

I wrote this blog as a primer for those who are just getting started using java.util.Stream classes, or for those who haven’t had a chance to take a look at them until now. The quick topics below represent just a sampling of some of the ways to be more productive using java stream classes. Rather than providing a tutorial on how the classes are used, I’ll attempt to explain by example.

Creating A Custom Amazon Alexa Skill

Ryan Nguyen .NET, Azure, Conversational Apps, Programming, Tutorial 1 Comment

With the explosion of the internet of things (IoT), many companies are competing to create the best smart home ecosystem for consumers.

Amazon Echo, for instance, is a robust system that allows the user to interact with their smart devices via voice command. Alexa is the application that the Echo communicates with, essentially the brain of the Amazon Echo. It controls how your Amazon Echo communicates with your other smart devices and services. It can sync with a variety of smart devices including switches, thermostats, garage doors, sprinklers, door locks, music streamers, news outlets, and more. It also allows the third-party companies to create custom skills which are then accessible through the Amazon Echo.

In this blog I will discuss the Amazon Echo and its Alexa application. We will go through the process to create a custom Alexa skill about the Keyhole blog, paying particular attention to keywords you’ll need to understand when you create your own Skill. From there, we’ll show how to test a Skill via simulators and deploy it to your Amazon Echo.
