Richa Khurana commented on JCR-1940:
------------------------------------
WRT Comment-""both users have same node id in cluster configuration in
repository.xml" sounds like a major misconfiguration. If you have multiple
Jackrabbit instances accessing the same content, then they *must* be configured
as cluster nodes with separate node ids."
--- Please note that the node ids are different only, it was just an
observation that i added that the same exception stops to appear when we set
the same node ids
WRT Comment-"It is perfectly valid to get an InvalidItemStateException if two
different sessions (whether on the same standalone jackrabbit or on different
cluster nodes) write to the same node or add nodes to the same parent. See the
JCR specification, for example section 7.1.3.3:
http://www.day.com/specs/jcr/1.0/7.1.3.3_Invalid_Items.html "
Please be noted that each environment is pointing to jackrabbit repository in
the DB and not any shared folder on the Local File System
Please let me know if any more info is reqd.

> Environment: OS - Win 2000
> JackRabbit Jars - 1.5
> Reporter: Richa Khurana
>
> We have a enabled jackrabbit clustering. In this mode following exception
> occurs when 2 users simultaneouly add documents to Jack rabbit repository
> registered with node id 1 and 2 respectively-
> 14:59:55,312 ERROR [DocumentHelper] Exception occurred while adding a
> manually uploaded document to the jackrabbit:
> javax.jcr.InvalidItemStateException: cafebabe-cafe-babe-cafe-babecafebabe has
> been modified externally
> at org.apache.jackrabbit.core.ItemImpl.save(ItemImpl.java:1109)
> at org.apache.jackrabbit.core.SessionImpl.save(SessionImpl.java:846)
> Another observation is that when we disable clustering and both users have
> same node id in cluster configuration in repository.xml, the error doesnt
> appear.
