Administration of IBM WebSphere Application Server Liberty Core (Part 1)
by Bhargav Perepa

This article provides a gentle introduction to IBM’s latest release of WebSphere Application Server Liberty Core v8.5.5 and its administration.

Administration of IBM WebSphere Application Server Liberty Core (Part 2)
by Manu T. George and Murali Surampalli

In the second part of this series, we will continue looking into the administration of IBM’s latest release of WebSphere Application Server Liberty Core v8.5.5. In this article, we look at certain aspects of JEE administration such as classloaders, component startup, the transaction service, database connectivity, connection pooling, server configuration updates and logging. We can administer the Liberty Core server in many ways. Part 1 of the article utilized the IBM Websphere Application Server’s Developer Workbench tooling that is layered upon an Eclipse instance. In part 2 of this article, we are going to illustrate directly editing the server.xml file which is the vendor specific configuration file that is required for configuring the Application Server. Different configuration snippets can be defined in different files and then imported into a single server.xml in case a more modular configuration approach is required. A bootstrapping.properties file can be optionally defined in order to externalize the values of properties defined in server.xml. We would use the WebSphere Developer Tools (WDT) during certain configuration steps to further illustrate the use of the tooling for configuration of the server.

Monitoring JEE application invocation over a Transaction Gateway for Availability
by Vivek Arora

JEE Applications can make external calls over a Transaction Gateway to leverage business logic from the Legacy CICS programs but may encounter operational problems due to some troublesome or exceptional scenarios which would require monitoring of the transactional requests. Understanding of how the JEE application is developed using the IBM External Call Interface (ECI) and deployed with a 3-tier architecture as well as how the Transaction Gateway has been configured for the threads and ECI timeouts would form the basis of any effective troubleshooting.

Selenium 2 WebDriver – How to automate web applications using Selenium WebDriver with Java
by Jaison Guglielmi

Selenium WebDriver is an open source suite of tools that enable developers and QA’s the ability to automate GUI tests in a variety of languages. It is compatible with many frameworks and boasts a huge support community and following. Based on a sample of IT jobs looking for people with Selenium experience using dice.com nationally in the United States, I discovered 995 entries for the term “selenium” compared to 738 entries for the term “QTP” which is another widely used tool within the automation community.

Why do you need sophisticated Object identification and management for Selenium Webdriver…
by Chetan Shah

Recently, I was attending a session on best practices in test automation. One of hot-button topic between the attendees was Object Management. There were lots of inputs about how to identify run time objects, objects changing properties, etc. there were answers coming all around. To my surprise, the topic did not extend further. For majority of them this is what Object Management means!

Grabbing the elements in Selenium
This article is going to explore the different ways in which we can identify an HTML element for authoring your tests. This will also help you understand which identifier to use when multiple identifiers are present for the same element.

Building Enterprise Applications using Java Data Objects – Best Practices to Avoid Memory Leaks

Java Data Objects (JDO) provide Java developers an interface for database related transactions (primarily SQL-oriented operations). However, many performance issues creep up while using JDO. The trickiest of them all being memory leaks in the application.

The Ubiquitous Yet Overlooked Anti-Pattern: Keyword new
by Bill Yao

Do you ever give a second thought when you use the keyword ‘’new’’ while coding a Java application? Have you ever suffered pangs of anti-OO guilt when creating yet another concrete Java class, instead of designing a Java interface? In this article, you will learn why the keyword “new” can be classified as an anti-pattern and how you can avoid including this popular but potentially deleterious Java keyword in your object-oriented code designs

Covering Your Assets
by Sue Spielman

Intellectual property (IP) is considered by many technologists to be the true pot of gold in software engineering. Every product created and every line of source code written falls into the category of some form of IP. In most technology companies, it is not uncommon to be under a constant state of deadline delivery. The consideration for the intellectual property, along with how to maximize and protect your product development investment, is put onto the back burner.

Gradle is a task-based build and test tool for the Java Virtual Machine (JVM). Gradle’s build scripts are written in Groovy; which has a lot in common with Java. Gradle combines the flexibility of Ant and the dependency management and conventions of Maven. Java unit tests provide a mechanism to test production source classes. The most commonly used Java unit testing frameworks are JUnit and TestNG. Gradle provides support for both JUnit and TestNG with provision to run the testing frameworks separately or together.

Be aware of Character Encoding in Java on multiple platforms
by Laurence England

When dealing with files that may have originated on platforms other than the one you are working on, it is necessary to be aware of the character encoding of the file. Incorrect handling of this issue for the related files can result in many wasted hours on debugging, especially when files have originated on one platform and then moved to another platform.
