Transaction over multiple workspaces?

[Jan Grathwohl]

Hi,

is it possible in Jackrabbit to have a transaction that spans  
multiple workspaces? What I would like to do is to start a  
UserTransaction, write changes to several Jackrabbit workspaces (all  
from the same repository) and a Hibernate session, and then commit  
all these changes together. My application modifies several  
workspaces concurrently, and I would like to ensure that all these  
changes are either commited or rolled back completely.

I have set up a JCA deployment of Jackrabbit 1.3.1 in JBoss , and it  
works fine as long as I only use one session per transaction. It  
looks from my tests like it is not possible to open more than one  
session within a transaction, and I also found a thread on the  
mailing list that says something like that.

But if I want to work in multiple workspaces, I have to open multiple  
sessions, because session are always per-workspace, right?

So my code to edit multiple workspaces within one transaction would be

                InitialContext ctx = new InitialContext();

		UserTransaction utx = (UserTransaction)ctx.lookup("java:comp/ 
UserTransaction");
                utx.begin();

                Repository repo = (Repository)ctx.lookup("java:jcr/local");
		Session session1 = repo.login(new SimpleCredentials("admin",  
"admin".toCharArray()), "workspace1");	
		Session session2 = repo.login(new SimpleCredentials("admin",  
"admin".toCharArray()), "workspace2");
                
                // Use session1 to write changes to workspace1
                
                // Use session2 to write changes to workspace2
                
                session1.save();
                session2.save();
                
                utx.commit();

which doesn't work.

Is there any way to include multiple workspaces within the scope of  
one transaction?


Thank you.
