Re: 2 questions about the beta

I guess you do not call the store from the WebDAV layer, do you? All 
write operations require an active transaction as more than one DB 
request is done. Thus you should be fine if you start a transaction 
before calling those methods.

Cheers,

Oliver,

I notice that some methods in AbstractRDBMSStore such as retrieveObject() has
the code as you mentioned below.

As far as I remember no transaction is started for a GET. There are
other methods you will not need a transaction for. That's why 
I open a 
temporary connection when there is no active transaction and thus no 
connection associated to it. The code looks like:

        if (getActiveTransactionContext() == null) {
            Connection connection = null;
            try {
                connection = getNewConnection();
                return adapter.retrieveObject(connection, uri);
            } catch (SQLException e) {
                throw new ServiceAccessException(this, e);
            } finally {
                if (connection != null) {
                    try {
                        connection.close();
                    } catch (SQLException e) {
                        getLogger().log(e, LOG_CHANNEL,
Logger.WARNING);
                    }
                }
            }
        } else {
            return 
adapter.retrieveObject(getCurrentConnection(), uri);
        }

This works fine with Slide's internal JTA implementaion, but
I have no 
idea what about Tyrex or other implementations more compliant to the 
spec. Would be interesting to find out though...



I wonder why it isn't done in all other methods.  I ran into
NullPointerException due to No active transaction when grantPermission() is
called.
