Check out Spring on your favorite social network! Glyn Normington has just announced the Eclipse Virgo 3.0.0.M01 release is now available for download. The new version features tighter integration with the Eclipse stack, including the Eclipse Virgo Jetty server. Additionally it features tighter integration with Equinox.

The first post introduces Spring 3.1 M1, generally. The second post introduces Spring 3.1's "profiles," which let you partition your beans along environment-specific lines with Environments. The third post introduces the Unified Property Management capabilities of the Environment abstraction.

A reminder: Juergen Hoeller - lead of the core Spring framework and contributor to all of the sister Spring projects, in some fashion or another - is giving two identical webinars - one for North America and one for Europe - on the new features in Spring 3.1 in two days (February 10th)! Be sure to register for this free webinar on the next iteration of the most widely used Java framework! This is turning out to be a record event, with incredible advance registration numbers. While there are no Spring 3.1 binaries (yet; stay tuned!), the code for the Spring project is always at your…

the Activiti BPMN 2 engine using Spring from earlier last month. With all the exciting news of Tomcat 6 and 7, it's easy to forget that Tomcat 5 is still being updated and supported. Tomcat 5.5.32 has also just been released!

To test it, open up a new shell and issue the following command: ./pom.xml ./src ./src/main ./src/main/java ./src/main/resources ./src/test ./src/test/java ./src/test/resources At the root of the directory structure is a XML file (always called pom.xml) that Maven expects. The pom.xml (POM is short for Project Object Model) describes the things specific to your project that can't be inferred automatically like dependencies, the name of the project, etc. Directory Description Directory's Contents (relative to the project root) src/main/java Contains the Java source code for your…

All applications stem from a domain model. The term "domain model" describes the nouns, or data, in a system that is important to the problem you're trying to solve. The service tier - where business logic lives - manipulates the application data and must ultimately persist it (typically, in a database). The explanation is simple, but in practice building a good service tier can be a daunting task for any developer. This post will introduce developers to the options available in the Spring framework for building a better service tier. It is assumed that the reader has some experience with the…

The Spring framework emerged as a de-facto standard in 2003 and has been helping people build bigger, better applications with cleaner code ever since. In this post, we will discuss the options available to you for configuring an application using the Spring component model. We will grow a simple application from the simplest form and rework it to take advantage of some of the many simplifying features in the Spring framework that have made it, and continue to make it, the de-facto standard for applications today. The modern day enterprise Java application has many collaborating objects that…

There are many ways to skin a cat. Many applications today rely on messaging (AMQP, JMS) to bridge the gap between disparate systems and data. Others rely on RPC (typically web-services, or REST). For a great many applications, however, file transfer is very much a way of life! There are several common ways of supporting it, but three of the most common are using a shared mount or folder, using a FTP server, and - for more secure exchanges - using SSH (or SFTP). While it's common knowledge that Spring has always provided first-class support for messaging (JMS, AMQP) and RPC (there are far too…
