This article was written based on IBM WebSphere Portal (hereafter called “Portal”) 7, and the portlet was tested on Portal 7 Fix Pack 2. It will be useful for Portal implementers who need to customize Portal 7 features, using an API or Service Provider Interface (SPI) to suit customer requirements, including customizing menu displays, portlets display on a page, user registration and the user management module. To get the most from this article, you should have basic understanding of Portal configuration and JavaTM Portlet Specification (JSR) portlet development.

IBM WebSphere eXtreme Scale is a powerful product for scalable high-speed storing and processing of data. WebSphere eXtreme Scale itself is transactional but is often used with other software products that are also transactional. Integrating these transactions, especially integrating WebSphere eXtreme Scale into an XA (global) transaction, can be far from trivial. This article explains two techniques for integrating WebSphere eXtreme Scale and other transactional products so that work for all can be reliably committed in a single transaction that follows ACID principles. Sample code for...

IBM WebSphere Application Server JCA connection manager provides connection pooling and enables administrators to establish a pool of connections that can be shared by applications running on an application server. However, the sharing of a JCA connection across multiple threads by an application can result in various exceptions. This article describes some of the application coding practices that lead to connection sharing across multiple threads, and explains the multi-threaded detection capabilities provided by WebSphere Application Server.

The Modern Batch feature for IBM WebSphere Application Server provides a robust Java batch programming model that enables the integration of online and batch processing within an architected framework across multiple platforms. This series describes the programming models that the Modern Batch feature provides and demonstrates the new functionality provided in IBM Rational Application Developer V8.0 that greatly simplifies the development of batch applications and the associated xJCL required for job submission. Part 1 introduced Modern Batch and showed a sample implementation for the...
