JBoss has acquired distributed transaction monitor and web services software from Arjuna Technologies.

JBoss is open sourcing ArjunaTS and Arjuna’s Web Services Transaction implementation in their JEMS offerings. Like all JEMS products, these offerings will run independently as free-standing products or on any J2EE application server.

I know atleast a few would be wondering where Arjuna Technologies is located. Their web site says, Arjuna Technologies was formed from the former Hewlett- Packard Arjuna Lab, and is now based in UK.
