hi Darko.<br><br>No that is optimistic locking. When they are opened there is no lock or anything. The second one failed cause it was stale data. <br><br>To do more aggressive locking would be trickier (as they you have to have a means to unlock things). There could be a more active type thing that warns people someone has something open (but of course its stateless, so its only "best guess"). This is like
99.9% of other apps out there, you have to make a decision on how to treat this locking scenario. Would be interested to discuss more about it though, as it is something that you are interested in.<br><br>This is all talking about a single BRMS server, with muliple clients.
<br><br>If you mean multiple BRMS instances, then more work needs to be done to configure jackrabbit to share indexes etc. Is that what you mean? <br><br>Michael.<br><br><div class="gmail_quote">On Nov 22, 2007 10:15 PM, Darko IVANCAN <
