Some are not transactional and do not support versions very well. -----Original Message----- From: Anil K.

But how do you have the connection set up and are you certain you're closing all connections once their finished? -----Original Message----- From: Anil K.

I have a method which can be accessed by multiple users. In the method i have following three statements. Node node = rootNode.getNode("document"); node.checkout(); node.setProperty("fileName",fileINputStream); node.save(); session.save(); node.checkin(); for a single user it is working properly. but when multiple threads are accessing the method it struck at node.checkin() statement. It is executing all the above statements. how to overcome this issue? any suggestions welcome. THanks in advance. Thanks, Anilk.
