Hi Teodor,

Can you explain the built-in system parameter REPORT_CONNECTION ?

...
<connectionExpression>
$P{REPORT_CONNECTION}
</connectionExpression>
...

Thank you,
Acharat

Hi,

When you supply a java.sql.Connection object instead
of a dori.jasper.engine.JRDataSource object, at report
filling time, the engine keeps a reference to this connection
object in the parameter called REPORT_CONNECTION.

This could be useful when passing further the connection
to the subreports.

There is also the REPORT_DATASOURCE parameter
which points to the JRDataSource object received or
created behind the scenes after the execution of the SQL
query.

And the REPORT_PARAMETERS_MAP which points
to the received java.util.Map object containig the
parameters values supplied when filling the report.

Good luck!
Teodor

Hi Teodor,
I would like to know more 'bout your system built-in parameters. I think it's helpful to reduce my effort of creating my own variables in .xml files.
Thanks,
Tam

Hi,

There is only one more built-in parameter
that I forgot to mention:
REPORT_SCRIPTLET
It holds a reference to the report's scriptlet object
and you can see it being used on the last page
of the "scriptlet" sample.

There is really nothing more I could tell you
about the built-in parameters...
There are no such JasperReports big secrets.
:)

I hope this helps.
Teodor

Hi,

I used this parameter REPORT_DATASOURCE with my xml, but when I compile this file I got the follow message:

- Parameter not found REPORT_DATASOURCE.

What's the problem?

Thanks

Victor

Hi,

Sorry, my mistake...
It's REPORT_DATA_SOURCE.

Thank you,
Teodor
