> Just mind that the unsecure key is configured only on the test repository.xml
that doesn't make it secure... the problem is that that value should not be
stored as plain text value in a file that is
readable for everyone that can write "new File....".
i am really not happy with that and i want this to be addressed before this
feature is being released in a stable
jackrabbit version. 2.7 is an instable branch so i consider this a temp.
solution.
-1 for merging this to the stable 2.6.x branch
-1 for any 2.8 release that contains this.
> Efficient copying of binaries across repositories with the same data store

> we have a couple of use cases, where we would like to leverage the global
> data store to prevent sending around and copying around large binary data
> unnecessarily: We have two separate Jackrabbit instances configured to use
> the same DataStore (for the sake of this discussion assume we have the
> problems of concurrent access and garbage collection under control). When
> sending content from one instance to the other instance we don't want to send
> potentially large binary data (e.g. video files) if not needed.
> The idea is for the sender to just send the content identity from
> JackrabbitValue.getContentIdentity(). The receiver would then check whether
> the such content already exists and would reuse if so:
> String ci = contentIdentity_from_sender;
> try {
> Value v = session.getValueByContentIdentity(ci);
> Property p = targetNode.setProperty(propName, v);
> } catch (ItemNotFoundException ie) {
> // unknown or invalid content Identity
> } catch (RepositoryException re) {
> // some other exception
> }
> Thus the proposed JackrabbitSession.getValueByContentIdentity(String) method
> would allow for round tripping the JackrabbitValue.getContentIdentity()
> preventing superfluous binary data copying and moving.
