Subject Re: autcommit in DatabaseJournal.append
Date Tue, 04 Dec 2007 09:14:35 GMT
Hi Dainius,

your configuration looks fine to me and I don't think you're using
DatabaseJournal incorrectly. You're using Jackrabbit 1.3.3, right?
When appending new entries to the journal, the order of calls on the
journal and corresponding actions on the database connection is as
follows:

Journal       Connection

lock()         autocommit=false
append()    commit or rollback
unlock()     autocommit=true

In your stack trace commit() is called while the connection is in
autocommit mode, which implies that some other component already
unlocked the journal. I'm going to investigate the calls made on
behalf of the journal when a transaction - updating both a workspace
and the versioning space - is committed.

Kind regards
Dominique

the database journal.

a resource environment reference in a session bean. When the container attempts to commit
or rollback the transaction an error is thrown because DatabaseJournal.append has called connection.commit
and attempted to set autocommit to true. Are we using DatabaseJournal incorrectly?
