If a parameter is set to be used as a prompt, when a report is executed, Jaspersoft Studio asks for the value of the parameter.
To create a parameter prompt:
Create a simple report with the template Blank A4, name ParameterExample and data adapter One Empty Record - Empty Rows.
| 1. | In this report create a parameter and rename it (from its properties tab) to MESSAGE, with type java.lang.String set to be used as a prompt (check the box next to the property Is For Prompting). |
| 2. | Drag the parameter from the outline view inside the Title band and Jaspersoft Studio creates a text field to display the parameter value. |
You should have something like the following image:
|
|
|
Parameter in Title Band |
To compile and preview the report:
| 1. | Click the Preview tab. |
Be sure the Input Parameter window is open. If not, click the gray right-arrow to the left of the Preview screen.
| 2. | Add a value for the MESSAGE parameter. |
For this example, type Parameter Example.
| 3. | Press the Play button. The message is printed in the title band. |

Jaspersoft Studio provides input dialogs for parameters of type String, Date, Time, Number, and Collection.
