something like this will show the jasper viewer:

 

public static void viewReport(JasperPrint jp) {

try {

if (jp != null)

JasperViewer.viewReport(jp, false);

}

catch (Exception e) {

}

}

 

you need to create a jasper print object and pass it to that method... No much sense in making an example of that since there is way too many different ways of filling up reports... It's easier if you check demo/samples/datasource example that comes with the source for jasper reports.

 

To pass parameters to a jasper reports you just create a hash map, put parameter keys and values in and then pass it to the jasperFillManager like:

 

Map parameters = new HashMap();

parameters.put("reportWhereClause", 'WHERE ID >0");

jp = JasperFillManager.fillReport(ClassLoader.class.getResourceAsStrea

m("/com/whatever/swing/reports/AReport.jasper"), parameters, cn);

 

Hope this helps... but check the examples in the demo/samples directory, they have all you need...
