Scott, we are nearing the end of a design phase which will provide the basis for public consumption and the beginning of a development community. Expect to see more later in February.
The Beta release schedule has not been set. We are still aiming for a JBI-enabled platform late 3Q06 which would support some ESB functionality (such as messaging and web services). ESB 2 in 2007 is aiming to be a fuller ESB platform.
I should point out that signficant ESB capability is available today or soon in JEMS (e.g., jBPM, web services, JMS, Rules soon).
I'm going to start uploading information about the design and architecture of JBossESB over the next few days.
Pierre and Mark,
Thanks for the updates. I'll keep watching this forum for new developments.
I've started to post a few thoughts on direction that Kevin Conner and I have been discussing. Feel free to comment, or check out the Labs ESB page when it goes live (soon).
