SpringSource launches Java application server

April 30, 2008 —

SpringSource,
maker of the Spring Framework for Java development, will announce a new application
server on Wednesday that it claims will "liberate" Java users from
"antiquated legacy Java technologies."

Dubbed the SpringSource Application Platform, the server combines Spring technologies
and the Apache Tomcat server with the increasingly popular OSGi (Open Services
Gateway Initiative) framework for Java development.

OSGi "enables a more dynamic, less constricted Java" because it enables
applications to load modules of Java classes on demand, Redmonk
analyst James Governor wrote in a recent blog post: "There is no need
to load the entire Java stack to run an application - just the runtime services
it actually requires."

For the new release, SpringSource has developed the Dynamic Module Kernel (dm-Kernel),
which makes working with OSGi simpler, according to the company.

"OSGi is very difficult to use out of the box," said SpringSource
CEO Rod Johnson. Customers and systems integrators whom the company has spoken
with regarding OSGi are "all enthusiastic about the benefits, but have
pulled back from trying to use it."

The product is now in beta at SpringSource's Web site. The company is planning
to release open-source and commercial versions in June. Pricing is still being
determined, but will be "competitive" with other offerings, Johnson
said.

SpringSource is releasing the new functionality -- which, besides the dm-Kernel,
includes a management console and assorted other plumbing, according to Johnson
-- under the GPLv3 open-source license.

With the launch, SpringSource has essentially packaged up ongoing practices
in the Java community, said Michael Coté, another Redmonk analyst. "What
they're doing is taking the use case of Tomcat and Spring and some other JEE
goodies and putting it into a 'product,'" he said.

The effort should not be taken lightly, Coté suggested: "The Spring
Framework has revolutionized the use of Java for sure, and I wouldn't dismiss
SpringSource's efforts to put that further."

Efforts like SpringSource's reflect OSGi's growing role on the server side.
