Subject [jira] Commented: (DERBY-2620) embedded throws SQLState 8003 (No current connection) on rs.next() on closed resultSet in test for DERBY-1025 in DataSourceTest
Date Fri, 11 May 2007 23:47:15 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2620?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12495207
] 

Kathey Marsden commented on DERBY-2620:
---------------------------------------

Currently, since xa end sets the application to null, so we get the 8003 (No connection) message
if we try to use the resultset,  Could you explain the logic behind setting the applicationConnection
to null in XATransactionState.end()

> The following code checking that a CLOSE_CURSORS_AT_COMMIT ResultSet is closed by xa_start
 throws the wrong exception for embedded, indicating that there is no current connection instead
of the ResultSet  being closed.

ResultSet.CLOSE_CURSORS_AT_COMMIT);
>         ResultSet rs4 = s4.executeQuery("select i from autocommitxastart");
>         rs4.next();
>         assertEquals(1, rs4.getInt(1));
>         rs4.next();
>         assertEquals(2, rs4.getInt(1));
>         // XAResource().start should commit the transaction
>         try {

>             xac4.getXAResource().end(xid4a, XAResource.TMSUCCESS);

>         // DERBY-1025.
>         // With Embedded, this will give error: 08003 - No current connection
>         // But with NetworkServer / DerbyNetClient, the transaction does not
>         // appear to be closed, and we actually get a value.
