RE: Jahia Clustering - JMS

Hi,

All the certified J2EE application servers provided by the usual commercial 
vendors (IBM; BEA; SUN;...) supports JMS as this is part of the J2EE 
standard. So on top of which platform are you currently runnning Jahia? If 
you run Jahia on top of Tomcat, why would you prefer a commercial JMS 
server but are using an open source servlet container? And you also have 
commercial companies supporting open source (JMS) implementations (e.g. Jboss)?

Else we may switch to JGroups in the near future for performance reasons 
(at the place of JMS) so, make sure, if you do not take a low cost open 
source solution, to verify that your commercial vendor also support JGoups 
else you may loose your investment.

Cheers,
Stéphane
