The data set is configured and the parameters are also inside the application, but it is not working or inside the "emulator" of Jasper.
The field asks for the value, after placing it it executes and brings the blank page, but this if I enter a valid value, if invalid there is error in the search.
Thanks in advance!
Could detail how the query is in your report and what value is being passed, could be some problem in how the parameter is, if it is
$P{parametro}or$P!{parametro}. I suggest reading the link: http://community.jaspersoft.com/documentation/tibco-jaspersoft-studio-user-guide/v60/using-parameters-queries– hebertrfreitas
