Hi,
I found this problem back in early march and submitted a patch by email.
Apparently in the move to sourceforge it got lost. I've resubmitted it to
the sourceforge patch page. Patch # is 424399. Christian, you might add the
bug # to the patch if you submit a bug. This patch is against 2.3 cvs but
the same modifications worked with 2.1.
My theory is that if you stop a XADatasource, you want a new copy when you
restart it. At least the pools don't seem to be amenable to
reconfiguration. So my fix frees the old source when the mbean is stopped,
and a new one is created when the mbean is restarted. Also, if the
connection can't be established when the pool is initialized, it's freed so
you can change the configuration and try again without restarting the
server.
Thanks
