Description: JDBC error behaviour incorrect
Details:
Hi
Here is my code snippet:
<--
public Hashtable retrieveApplicationParameters() {
PreparedStatement ps = null;
ResultSet rs = null;
String loadApplicationParameters = " SELECT key_id, key_value FROM
application_parameters WHERE is_active = 1";
Hashtable values = new Hashtable();
try {
DBActions db=DBActions.getInstance();
rs = db.getConnection().prepareCall(loadApplicationParameters
).executeQuery();
while (rs.next()) {
// Testing
values.put(rs.getString(1), rs.getString(2));
System.out.println(rs.getString(1)+","+ rs.getString(2));
}
} catch (SQLException sqle) {
logger.error("Could not load application parameters ", sqle);
}
catch (Exception e){
e.printStackTrace();
}
catch (Throwable e){
e.printStackTrace();
}
/*finally {
DBConnection.close(rs, ps);
}*/
return values;
}
-->
In this code, the program gets to the executeQuery part with no exception.
When it gets to the rs.next() part, the code jumps to the finally block.
This is non-deterministic behaviour as the code seems to have thrown an
exception, but even the catch Throwable part does not catch the error.
The database being connected to is a restore from another database. The fact
is this database restore could be incorrect, but how can I find the actual
error
cause of the problem. Is there a way to increase the logging so that I can
figure out the problem here.
Sorry I can't give more info than this until i can learn how to turn the
debugging for the jdbc driver and so on.
