Check out this in­ter­est­ing pre­sen­ta­tion on In­foQ by Ce­sare Pau­tas­so.

We at Atomikos are work­ing with Ce­sare to re­search REST and Trans­ac­tions and how to in­te­grate this with BPM for REST as well; check out this slideshare pre­sen­ta­tion (also by Ce­sare).

Good news: we've fi­nal­ly re­leased our 3.7.0 re­lease, with im­proved per­for­mance as the main fo­cus. Although pre­vi­ous mile­stone builds have been re­leased on re­peat­ed oc­ca­sions, this is now the of­fi­cial 3.7.0 re­lease for both Trans­ac­tion­sEssen­tials (open source, not sup­port­ed) as well as Ex­tremeTrans­ac­tions (not open source, sub­scrip­tion-based avail­abil­i­ty, with sup­port).

To down­load, pro­ceed to our home­page.

As per our new poli­cies, the open source Trans­ac­tion­sEssen­tials prod­uct is now also avail­able via maven cen­tral - in­clud­ing clean poms, sources that match the bi­na­ries and all oth­er things that maven users de­serve...

Over the next months we will be work­ing with 2ndQuad­rant to im­prove the Post­gresql XA func­tion­al­i­ty and stream­line com­pat­i­bil­i­ty with Atomikos prod­ucts. Dur­ing this time, we will grad­u­al­ly elab­o­rate an XA com­pat­i­bil­i­ty test kit that will serve both as a test tool and a learn­ing suite for XA fea­tures in data­bas­es in gen­er­al.

It has hap­pened a cou­ple of times that peo­ple have asked me how to start­up only the re­cov­ery part of their ap­pli­ca­tions. While there is no built-in sup­port in Atomikos (for now), here is a way to do it with Spring:

• Con­cen­trate your DataSource, Con­nec­tionFac­to­ry and Trans­ac­tionMan­ag­er bean de­f­i­n­i­tions in one con­fig file, say in­fra­struc­ture-con­fig.xml (the term will sound fa­mil­iar to those who prac­tice Do­main-Driv­en De­sign (DDD)
• Use this con­fig file in your ap­pli­ca­tion; this is your full run­time
• Create a sep­a­rate Main that ini­tial­izes Spring with noth­ing else but this con­fig; this will be your re­cov­ery-only ru­time

Voila! En­joy...
