EJBs in BlueMix (with JPA: DB2 and MySQL backends) (packaged server)

This article will use a BlueMix JPA Sample Application with a db2 or mysql database driven by either EJBs or Servlets. JPA (Java Persistence Architecture API) is a set of APIs that is used for reading and writing data to databases via Java objects. An EJB (Enterprise Java Bean) is a server side Java object that contains business logic with special qualities of service (collaborators) such as transactions and security. We’ll provide some code snippets for EJBs and JPA, and also explain the packaging required for deploying this type of application to BlueMix.

Mad Dash: a Node.js Application Dashboard

As a follow up to my previous blog post, where I showed how to set up a real-time console log web tail for your Node.js application, I will be demonstrating how to use socket.io to instrument a web application. This is not meant for production level code, but instead to serve as an example of how a developer could instrument their web application in a few short steps and how they could expand it without much effort.

A Live Look: How to Observe Your Node.js Application Logs in Real-Time

In this article, I’ll be demonstrating how you can add a “live” console web tail to your Node.js application hosted on BlueMix in a few easy steps without cluttering up your application code. We’ll be achieving this by overloading the Console object, something you find in almost every javascript program. This is a handy feature for real-time debugging as well as monitoring your running applications. It also serves as a prototype for modifying console statements or adding entirely new console types.
