Alliance of 2 open-source companies: SpringSource buys Covalent

By Margarita Snegireva. An open-source software company SpringSource Inc. reported that it bought Covalent Technologies Inc.

SpringSource Inc., which focuses on open-source software for building and deploying mission-critical enterprise applications, said Tuesday it acquired Covalent Technologies Inc.

San Mateo-based SpringSource did not disclose financial of other terms of the deal.

Walnut Creek-based Covalent is the provider of support and services for Apache Software Foundation open-source projects. Covalent has a customer base of more than 400 organizations and more than 50 percent of the Fortune 500 and 20 percent of the Global 2000, SpringSource said.

The Spring Framework (or Spring for short) is an open source application framework for the Java platform. The first version was written by Rod Johnson, who first released it with the publication of his book Expert One-on-One Java EE Design and Development (Wrox Press, October 2002). A port is available for the .NET Framework.

The framework was first released under the Apache 2.0 license in June 2003. The first milestone release was 1.0 which was released in March 2004 with further milestone releases in September 2004 and March 2005.

Although the Spring Framework does not enforce any specific programming model it has become popular in the Java community as an alternative, replacement or even addition to the Enterprise JavaBean model. By design, the framework offers a lot of freedom to Java developers yet provides well-documented and easy to use solutions for common practices in the industry.

While the core features of the Spring Framework are usable in any Java application there are many extensions and improvements for building web-based applications on top of the Java Enterprise platform. Spring has gained a lot of popularity because of this and is recognized by vendors as a strategically important framework.
