Dear Spring Community,

We are pleased to announce the release of Spring LDAP version 1.2. This is a major release that introduces a number of features and bugfixes.

A summary of the more important changes:

• Java 5 Generics support is now provided with the SimpleLdapTemplate and ParameterizedContextMapper classes.
• Client-side LDAP transactions.
• Several additional API methods, simplifying a number of common tasks.

About Spring LDAP
Spring LDAP is a Java library for simplifying LDAP operations, based on the pattern of Spring's JdbcTemplate. The framework relieves the user of the burden of looking up and closing contexts, looping through NamingEnumerations, encoding/decoding values and filters, and more.

The LdapTemplate class encapsulates all the plumbing work involved in traditional LDAP programming, such as creating, looping through NamingEnumerations, handling Exceptions and cleaning up resources. This leaves the programmer to handle the important stuff - where to find data (DNs and Filters) and what do do with it (map to and from domain objects, bind, modify, unbind, etc.), in the same way that JdbcTemplate relieves the programmer of all but the actual SQL and how the data maps to the domain model.

In addition to this, Spring LDAP provides Exception translation from NamingExceptions to a mirrored, unchecked Exception hirearchy, as well as several utilities for working with filters, LDAP paths and Attributes.

Spring-LDAP requires J2SE 1.4 for running. J2SE 1.4 and javacc is required for building the distribution binaries from sources. J2EE 1.4 (Servlet 2.3, JSP 1.2) is required for running the example.

Where to start
Download the distribution from the link above. The distribution contains extensive JavaDoc documentation as well as full reference documentation and a sample application illustrating different ways to use Spring LDAP.

As some of you will have noticed already, Spring 2.5 RC1 has finally been released on Monday and is waiting for you to give it a test drive! Spring 2.5 is in many ways the release that completes Spring 2.0's mission: providing the most flexible and most comprehensive configuration model for both Java 1.4 and Java 5. Spring 2.5 focuses on particularly comprehensive support for Java 5, introducing various further annotations options. I'd like to take the opportunity to point out the unifying themes behind this release:

Spring 2.5 allows for convenient externalized configuration while also keeping it as concise as possible. This is building on Spring 2.0's support for XML schema namespaces, with Spring 2.5 introducing new "context" and "jms" configuration namespaces. The latter is a particularly good example for the value-add that a Spring configuration namespace can provide - definitely worth adopting if you're using Spring 2.0 style message-driven objects! Additionally, Spring allows for programmatic bootstrap with no XML involved as well…

Dear Spring community,

I'm pleased to announce that the first Spring Framework 2.5 release candidate is available! Spring 2.5 is the culmination of the effort that started as Spring 2.1 milestones, enhancing Spring 2.0 with many new features, such as:

• full Java 6 and Java EE 5 support (JDBC 4.0, JTA 1.1, JavaMail 1.4, JAX-WS 2.0, etc)  
• full-featured annotation-driven dependency injection (including support for 'qualifiers') 
• support for component scanning in the classpath (autodetecting annotated classes) 
• bean name pointcut element in AspectJ pointcut expressions 
• built-in support for for AspectJ load-time weaving (based on the LoadTimeWeaver abstraction) 
• further XML configuration namespaces ("context", "jms") for maximum convenience 
• completely revised framework for integration tests (with support for JUnit 4 and TestNG)
• new annotation-based controller style for Servlet MVC and Portlet MVC
• extended SimpleJdbcTemplate functionality (support for named parameters etc) 
• officially certified WebSphere support (support for the WebSphere 6 UOWManager facility) 
• Spring framework jars are shipped as OSGi-compliant bundles out of the box
• Spring ApplicationContext can be deployed as JCA RAR file (for headless application modules) 
• JCA 1.5 message endpoint management (for Spring-managed JMS and CCI message listeners)
  

Download | Documentation | Changelog 

Particularly worth mentioning are the annotation-based MVC controller style, the JAX-WS support and the TestNG support, all of which are introduced in this release. Furthermore, this release comes in three different distributions, introducing a minimal standard zip and an intermediate with-docs zip.

We recommend upgrading to Spring 2.5 from all previous 2.0.x versions, in order to benefit from the new features as well as from the significant performance enhancements that Spring 2.5 has to offer. Spring 2.5 is designed as a drop-in replacement for Spring 2.0, except for the slightly restructured jar file contents (see the readme file in the distribution).

Note that Spring 2.5 is still compatible with JDK 1.4.2+ and J2EE 1.3+. Java 1.4 users, for example on WebLogic 8.1 or WebSphere 5.1/6.0, are very welcome to upgrade to Spring 2.5 as well! We recommend putting the backport-util-concurrent jar on the classpath when running on Java 1.4, which allows Spring (and hence your applications) to benefit from significant concurrency enhancements.

You may have seen some of the recent press surrounding the announcement that Interface21 is partnering with Tasktop to create a "Spring Tool Suite". This suite will bring together Spring IDE, the AspectJ Development Tools (AJDT), AspectJ, and Mylyn to create a task-focused approach to the development of Spring-powered enterprise applications. We hope to have a preview of the integrated suite available to share with you at the forthcoming The Spring Experience conference, but in the meantime you'll see many of the improvements flowing into the existing Spring IDE, AJDT, AspectJ, and Mylyn open…

At last month's Gartner Open Source conference, analysts declared that open source had permeated a significant amount of the global software market. The details were highlighted in a recent Matt Asay blog that quotes the eWeek article. eWeek writes: “open-source products accounted for a 13 percent share of the $92.7 billion software market in 2006, but should account for 27 percent of the market in 2011 when revenue is expected to be $169.2 billion.”

At the same time, Gartner analysts Massimo Pezzini and Yefim Natis have published a report highlighting an important vein of disruption currently underway in the middleware and transaction processing markets. The September 24, 2007 report, titled “Trends in Platform Middleware: Disruption is in Sight,” highlights more than a dozen trends that “will disrupt the apparently static application server and transaction processing markets” and warns that…

As I've posted before, Interface21 is getting involved with the Java EE 6 effort, and various of our folk including myself, Juergen Hoeller, Keith Donald and Rob Harrop will be involved in a number of expert groups.

This means that we're getting more involved with the JCP in general. We respect the confidentiality and other provisions of the JCP, so we won't talk about anything that isn't public. However, I would like to talk about our goals for JCP involvement and the fundamental approach we will bring. Of course we are just one company among many companies and individuals, so we will just be…
