When managing and transforming as many bundles as are included in the the SpringSource Enterprise Bundle Repository, it becomes very difficult to remember what packages are boot delegated, exported from the system bundle, or from other bundles in your system. This information is important because you probably don't want to import packages that are boot delegated, you probably do want to import system bundle packages at "0", and you want to define custom imports for all others. Remembering which packages are in each of these categories ends up being a bit error prone and defining template…

Today we are pleased to announce the availability of Grails 1.1.1 which whilst providing many incremental improvements over Grails 1.1 also introduces official support for Google AppEngine.

Groovy itself has been running on AppEngine since its launch, but we had to make a few tweaks here and there in Grails to make Grails applications run on AppEngine.

Included in this is the introduction of an AppEngine plugin which replaces Hibernate with JDO (and soon JPA) for persistence in order to take advantage of Google's DataStore API. The AppEngine plugin also integrates the AppEngine development…

Introduction

Recently the M3 milestone of Bundlor has been released (Forum Anouncement). This milestone adds support for Property Substitution and Version Expansion. This blog post explains how to work with these new features to improve the quality of generated Manifests.

Property Substitution

Bundlor can now be used to substitute any property value into your Manifest Template.

Bundle-Name: ${name}
Bundle-Description: Test bundle using new version of Kernel at ${com.springsource.kernel}
Import-Template: com.springsource.kernel.*;version="${com.springsource.kernel}"

This syntax allows you to specify property placeholders for ${name} and ${com.springsource.kernel} and have them substituted at runtime with actual values. The way that these values are passed in is specific to which Bundlor front end is being used.

Specifying Properties at the Command Line

When Bundlor is run from the command line it will use all the properties available as system properties, this does not include any environment variables. The command line script will pass through any variables passed in via -D so the following will provide the ${com.springsource.kernel} property with a value of '2.0.0.RELEASE' and the ${name}…

It was April 27th around 2:39pm, when Rod announced in his SpringOne Europe opening keynote:

Reto Meier, with our partner namics, took a picture as proof of that very moment and published it on flickr.com. Also the audience at SpringOne seemed to be enthusiastic about the announcement and as a consequence the word was spread to outside of the conference soon after.

So here we are, since Rod promised it, we can't get out of it… ;-)

Today we are proud to deliver on Rod's promise and can announce that the first free versions of STS have been published and can be downloaded from the product page…

We are pleased to announce that the third Spring 3.0 milestone is available now (download page)! This release comes with many new features and refinements, including...

Reference documentation: M3 is the first Spring 3.0 milestone that comes with reference documentation, in both HTML and PDF format. Even if the documentation is still a work in progress, it does cover many 3.0 feature areas at this point already. We hope that you'll find this early cut of the documentation useful for learning more about the 3.0 milestone features.

Annotated factory methods: Spring 3.0 M3 includes the core…

A few weeks ago, I laid out SpringSource's vision for creating a unified enterprise Java solution that spans the application lifecycle. Today, we announce a significant advance in realizing that vision: SpringSource's acquisition of Hyperic, which greatly strengthens our capabilities for the management of modern applications and infrastructure.

As SpringSource has grown, like the Spring open source projects, the company has taken on a wider range of problems. Today's announcement is the logical continuation of our push into the server space, and offers the potential to further simplify the…

The twittersphere has been abuzz this week with news from SpringOne Europe. One announcement generating a significant amount of interest is SpringSource's new open source productivity tool, codenamed "Roo".

Roo is a sophisticated round-tripping code generator that makes it quicker and easier than you've ever imagined to create and evolve Spring applications. Even if you have reservations about code generation, it will still be worth taking a look at Roo. It contains significant innovation that addresses all major objections to code generation, whilst still delivering best practice Spring…

The time is ripe for lightweight AND enterprise class Java application servers, and Apache Tomcat is the pick of the litter. And now, with SpringSource tc Server, we at SpringSource make it a reality.

If you were familiar with Covalent, and now SpringSource, then you most likely know about ERS (Enterprise Ready Server). ERS is our pre-built, pre-packaged and fully QA-ed distribution of the Apache httpd web server and Apache Tomcat. Included in the distro are also some very useful enhancements, in the form of modules, for Apache, such as PHP, mod_perl and mod_snmp. The somewhat unfortunate…

Last year, Oracle acquired BEA Systems, the hottest company in enterprise Java…until around 2001.

Today, they announced the acquisition of Sun Microsystems, the architects of the infrastructure of the dot com era. Remember the "dot in dot com"??

Both companies represent the history of enterprise Java, and are far less important to the future.

Larry Ellison states that “Java is the single most important software we've ever acquired."? Ellison is right about the importance of Java: Java is the world’s #1 programming language and the dominant choice of the enterprise. But the question is exactly what has Oracle acquired? There is no purpose to be served by Oracle trying to milk the Java language itself for profit--and, in any case, it's now open enough to make that impossible. (Open sourcing Java did turn out to matter. A lot.) And it is a long time since Sun controlled enterprise…
