This three-part tutorial walks you through building a multi-tier web application from scratch, using IBM® Rational® Application Developer, the Java Persistence API (JPA), Enterprise JavaBeans (EJBs), REST web services, and — for a rich Web 2.0 front end — the Dojo Toolkit. You'll end up with a fully functioning web application that displays data in a table that users can edit by double-clicking any cell.
Rapidly build a rich three-tier web app, Part 1: Build the database- The application architecture uses REST services to decouple the UI from the server, and it uses EJBs and JPA to provide a correctly tiered enterprise application. Some of these layers are unnecessary for the sample application, but the intent is to provide a well-architected example that can be scaled for a more challenging problem space. The high-level steps the tutorial follows are:
Rapidly build a rich three-tier web app, Part 2: Build the application tier- In part two of this three-part tutorial, learn how to use IBM Rational Application Developer and IBM Bluemix to rapidly build and host a multi-tier Java Enterprise Edition (JEE) app. Find out how you can save time in each stage: creating the data model and database, generating the data access code using the Java Persistence API (JPA), writing the Enterprise JavaBeans (EJBs) and web services, and using Dojo to create a rich web UI for viewing and modifying the data. When the application is complete, you'll deploy it to IBM Bluemix, the IBM Platform as a Service (PaaS).
Rapidly build a rich three-tier web app, Part 3: Create a rich web UI- In Part 1 you created a database on IBM Bluemix, connected to it from Rational Application Developer, and populated it with sample data. In Part 2, you created the application tier consisting of an EJB for managing the business logic and Java Persistence API (JPA) entities for interacting with the database. Here in Part 3 you'll expose the EJB methods as REST web services and build an editable Dojo data grid for viewing and modifying the data. Finally, you'll deploy the application to IBM Bluemix.

If you've not been to the Global Rational User Community (GRUC) recently, here's what you've been missing out on when it comes to DevOps conversations... below you will find a series of blog posts from the GRUC site that cover varying topics around DevOps strategies. We hope you find these as beneficial as we have!
Blog Post: Defining Disciplined DevOps - This posting, the first in a series, overviews a disciplined approach to DevOps. It begins by defining DevOps, no small task given the continued debate within the DevOps community, and then described a disciplined approach to DevOps. Defining DevOps For our purposes we propose the following definition: DevOps is the streamlining of the activities surrounding IT solution development […]
Blog Post: DevOps Strategies: General - In a previous blog posting we overviewed the concept of Disciplined DevOps, which is the streamlining of IT solution development and IT operations activities, as well as supporting enterprise activities. In this blog posting we begin to overview strategies that support DevOps. This posting overviews general strategies, and future postings will desc
Blog Post: DevOps Strategies: Development - In addition to the general stra
Blog Post: DevOps Strategies: Release Management Part 1 - In this blog posting we describe four general release management strategies that support DevOps. These strategies, from least effective to most effective, are: Release windows (slow cadence). A release window is a period of time during which one or more teams may release into production. A release slot is subset within that release window (and […]
Blog Post: DevOps Strategies: Release Management Part 2 - In addition to the general release management strategies described previously, the general DevOps strategies, and the cons
Blog Post: DevOps Strategies: Operations - In addition to the general DevOps strategies and development-focused DevOps strategies we’ve described previously, there are also several technical strategies that support the operations-aspects of DevOps: Solution monitoring. As the name suggests, this is the operational practice of monitoring running solutions and applications once they are in production. Technology infrastructure platforms such as operating systems, […]
Blog Post: DevOps: Strategies for Organizing Release Management - In this blog posting we describe two issues for organizing your release management strategy: How to scope release management and how to organize the team. There are two fundamental issues to consider when scoping your release management efforts: Paradigm support. Will your release management process focus on supporting one paradigm, such as agile/lean teams or […]
Blog Post: DevOps Strategies: Data Management - In the Disciplined Agile Delivery (DAD) framework data management is a Run (operational) activity that focuses on the execution of data-oriented architectures, policies, and processes. Note that the long-term planning efforts around data-oriented aspects of your organization are part of your Enterprise Architecture efforts. Similarly, development of the data-oriented aspects of your organizational eco-system is […]
Blog Post: DevOps Strategies: Enterprise Architecture - The Disciplined Agile Delivery (DAD) framework explicitly includes arch
Blog Post: DevOps: Operational Disaster Strategies - There are several disaster mitigation strategies that IT departments may choose to adopt: Disaster planning. Disciplined organizations will plan for operational disasters. Potential disasters include servers going down, network connectivity going down, power outages, failed solution deployments, failed infrastructure deployments, natural disasters such as fires and floods, terrorist attacks, and many more. This planning will […]
Blog Post: DevOps Teaming Strategies - There are several teaming strategies that you can choose to adopt when it comes to getting development professionals and operations professionals to work together. Starting with the least effective and working our way to the most effective, they are: Production hand-off. When a development team releases a solution into production the operations team takes on […]
Blog Post: DevOps Strategies: Support - In this blog posting, part of our continuing series on DevOps, we explore solution support strategies. There are several solution support (help desk) strategies, which can be combined, that you may choose to adopt. These options are: Online information. A very common “self serve” support strategy is to develop and maintain online assets such as […]
