Subject RE: Can't get an excerpt when using JCR Webdav I/F
Date Fri, 09 May 2008 15:27:49 GMT
 I guess this then merits a JIRA feature request when done across JCR/SPI

Question in general regarding architectures. I understand that SPI is going
through its growing pains, but what is the recommended model when I have a
farm of application servers that want to use Jackrabbit? My thoughts were to
use JCR Webdav/SPI to access a server running the Jackrabbit service from
any of the app servers internally.

If this is not yet mature enough, I will have to bundle jackrabbit with each
app server sharing a single dB repository with the obvious risk of stepping
on each other.

Hi Julio,

the rep:excerpt() function is jackrabbit-core specific and is not guaranteed
to work across the more JCR generic SPI layer.
