Subject Problems with FBXaDataSource in ApplicationServer
Author Sascha Horn
Hi all,

i am using JBoss 7.3.0 with Jaybird 2.2.4 to connect to an Firebird
In a ejb with container managed transaction i am using a
org.firebirdsql.ds.FBXADataSource to get a Firebird connection.

From this connections i create two statements.
Statement on executes a query and gets an resultset.
While i iterate though the rows and execute an other
query on statement2.

executing statement2 causes the resultset from statement1 is closed.

I googled a bit...
The solution should be to use setautocommit(false), but this is not
possible in an container managed transaction.

as a workarround i use setDefaultResultSetHoldable(true).
In my opinion the result set may not be closed within an managed
transaction, because commit and rollback should be invoked from the
managed transaction.

Can anyone confirm that this a bug in Jaybird driver?
Or am i doing something wrong?

An other problem is, that when rolling back the container managed
transaction every time the following exception occurs:

org.firebirdsql.jca.FBXAException: invalid database handle (no active

With an oracle DB and the matching oracle driver the rollback works, so
i guess it is a driver problem?

Thanks in advance.
