"Deployment of systems is really pretty awful in the current version of Java," Manes said. Using OSGi as a solution to this is a good idea, she stressed.
"I'm wondering why they needed to do the module support and not just go with OSGi support. But as long as the module support fully supports OSGi, that's OK," Manes said.
As part of Sun's plan to expand language support on the Java Virtual Machine, dependencies on just using one language on the JVM will be removed. Developers will have an easier time writing compilers and languages based on other languages and executing them on the Java platform.
Speakers noted that the planned GlassFish version 3 application server also supports OSGi. It will support dynamic languages such as Ruby and Groovy as well as Java EE 6.
Sprint executive Kevin Packingham, vice president of wireless product management and usability at Sprint Nextel, announced intentions to offer in the United States the Instinct phone, a touch-enabled Java handset.
Another technology touted at JavaOne on Tuesday afternoon, the Lightweight UI Toolkit, or LWUIT, features a UI library that allows developers to overcome challenges to building compelling, consistent Java applications for handhelds. Available in an early access mode, it will be offered via open source this summer.
A Sun blog describes LWUIT as a library that sits on top of MIDP 2.0 and implements a peerless graphics and UI model with a small footprint and moderate performance requirements. It leverages SVG graphics integration and Swing-live MVC (Model View Controller).
LWUIT runs on devices from companies such as Nokia and Sony Ericsson.

Server virtualization is a popular option for dealing with mounting datacenter costs. Another equally promising approach is the use of an Application Delivery Controller. Citrix NetScaler provides a low-cost way for organizations to reduce their server count and accrue cost savings from a reduction in space, cooling, power and personnel.
