Input Controls Created on Server

You can create input controls on the Jasper Server which is useful when you want to use the same input controls across many reports. For instance the multi-select input control may contain the same data for selection and it would save a lot of time to have that saved for use later.

Note: Input controls correspond to the parameters defined in JRXML reports, such as $P{name}. The server maps the value that the user enters for the input control to the parameter of the same name. If you define an input control in the JasperReport and the server can’t find a parameter by the same name in the JRXML, the input control doesn’t function when the report runs.
