node.checkin()

[Anil K. Kotha]

Hi All,
         I am using jackrabbit on Jboss server.
 
        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.
