Hi,
Nested transactions (as ISO, X/Open and OTS
define them) would not help in your scenario
since the inner transaction would also be
rolled back when the main transaction is rolled
back. This despite the fact that the inner
transaction was committed.
For your scenario, I would try to use a
resource that does not participate in
transactions.
Plain old non-XA JDBC connections are an
example of this.
Try setting up a non-XA resource by using
the org.jboss.jdbc.DataSourceLoader instead
of the org.jboss.jdbc.XADataSourceLoader.
Then use that data source for your
outside-of-transaction work.
Best Regards,
Ole Husgaard.
