ArjunaTS adds distributed transaction processing capabilities to the JEMS stack, a move designed to appeal to enterprises in sectors such as financial services and telecommunications where 'five-nines' availability is crucial. These capabilities include support for multimodal transaction processing across client/server, Internet, mobile and wireless, SOA and event-driven architectures and the ability to handle high transaction volume across diverse middleware environments straddling CORBA, J2EE and web services.

Arjuna's Web Services Transaction implementation delivers another key component of JBoss' expansion into SOA. As a co-author of the WS-TX and WS-CAF specifications, Arjuna has developed an industrial-strength web services implementation that uniquely supports both specs, JBoss says.

Among large players in web services, a line is being drawn between the specifications, with WS-TX supported by companies like Arjuna, Microsoft and IBM and WS-CAF supported by Arjuna, Oracle and Sun among others. With Arjuna's Web Services Transaction implementation as a core product, JEMS bridges the gap between these two camps and remains true to its inherent flexibility and platform-independence.

"HP is pleased to continue driving growth in the open source community with JBoss. This acquisition enables JBoss to expand the reach of open source into the enterprise by making a high-end distributed transaction processing technology readily available," said Christine Martino, vice president of Open Source and Linux, HP. "HP's leadership with JBoss continues to set the standard for open source solutions, and the addition of the Arjuna technology to JBoss JEMS increases choice and confidence for enterprise-class J2EE platform solutions."

JBoss expects to release ArjunaTS and Arjuna's Web Services Transaction implementation as open source JEMS offerings in Q1 2006 backed by JBoss Subscription services, training and consulting. Like all JEMS products, these offerings will run independently as free-standing products or on any J2EE application server. For more information, visit www.jboss.com/products/transactions.
