[carolopia]

hello everyone,
I have one report and different datasources, this datasources have the same estructure but are in different locations and I need generate the same report for every datasource.
I have the report in jasperserver because the users can access to look these ones. Can I create some kind of parameter with the connections to datasources and the users choose these ones depends that they need? or how can I resolve my problem? Have I to create the report in jasperserver for every datasources?

Important to know: The users don't have administrator permissons.

thanks for all your help.

Regards,

Caro.
