Register for Real-World Java Seminar In the first part of this article you learned how Java EE 5 has simplified enterprise application development by adopting a POJO programming model and making use of Java 5 metadata annotations. You also discovered how the Spring Framework version 2.0 integrates with Java Persistence API (JPA) and makes it simple to use from enterprise Java applications. In this second part, you will learn how you can integrate the Spring Framework with EJB 3 components and to exploit Spring's declarative transaction features with Java EE applications. Finally we'll discover how Java EE application servers provide seamless management of Spring components from their JMX-enabled management consoles. Using Spring and EJB 3 As we discussed in Part 1 of this article, EJB 3 greatly simplifies development of EJB components. Spring's Pitchfork project impl... (more)

Challenges with APM 1.0 products

I met several customers in the past few weeks who are evaluating Application Performance Management (APM) solution. They are facing a lot of challenges with their existing investments in old generation of APM solution. In this blog, I will outline some of the shortcomings with APM 1.0 tools that make them unfit for today’s applications. What is APM 1.0 Customers have been managing application performance since early days of mainframe evolution. However, Application Performance Management as a discipline has gained popularity in the past decade.   Let me first introduce what I me... (more)

Transaction tracing vs. Deep-dive Monitoring

I spoke to a few customers last week about Application Performance Management (APM) and many of them are still confused about the different functionalities offered by APM products, such as transaction tracing and deep-dive monitoring. I will use screens shots from BMC Application Diagnostics as illustrations.   Most of today’s applications are multi-tiered and involve a multitude of systems such as application servers, databases, messaging systems or external web services.  Consider the following example of a transaction where a user bids for a product offered in an auction sit...

Spring and Java EE 5 (PART 1)

Register for Real-World Java Seminar The Java Platform, Enterprise Edition, or Java EE, is the most popular middleware platform for developing and deploying enterprise applications. Java EE offers developers a choice of vendors, portability, scalability, and robustness. However, it has been criticized for its complexity and its need for a lot of redundant and procedural code. In addition, lightweight frameworks such as Spring and scripting platforms such as Ruby on Rails have emerged to challenge the platform's supremacy in the middleware world. In response, the Java Community Pr... (more)

Managing Complexity Within a BPEL Environment

Service-oriented architecture (SOA) has become mainstream technology for integrating disparate systems and applications. For building composite applications, Business Process Execution Language (BPEL) has emerged as the standard for business process flow orchestration and application integration within organizations. Many IT organizations are deploying composite applications that use BPEL to automate critical business processes. If your application needs to be available 24/7, you need a reliable BPEL infrastructure. In this article, we first present a typical BPEL engine archit... (more)
