two versions for filling the report, whhch one is the best??

[Alan Hermin]

hi all........
iam using jasper report, and when filling the report, i am passing the Connection to the jasper,and then jasper make a select query, like this:

JasperFillManager.fillReport(JasperReport, Map_of_myParams,Connection);

But i saw that there are a way that pass ResultSet as a data source,instead of Connection,and making select query before sending it to jasper like this:

JasperFillManager.fill report(JasperReport, Map_of_myParams,new JRResultSetDataSource(resultSet));

which one is the best use in many perspective , including performance?

I didn't know the second method. I use only the first one.

If the second has a better performance I would use that one.

I suppose that the resultset needs to be the same as from the query if you want a correct report.

Sorry for the second post which is the same.

I have received a message which states that I hadn't a connection so I thought there was no post.
