JasperFillManager.fillReport(...) - empty report!

[mikij]

 Hi,

I'm trying to implement JasperReports in my Web application (Struts 2-based). But, when report is shown I get just an empty page for a report! I don't get any errors or warnings in console. This is the code which I use for calling the report:

I first fill parameters:

Map params = new HashMap();

params.put("param1", new Long(1L));

...

and then call the report:

Class.forName(new String("com.mysql.jdbc.Driver"));

Connection conn= DriverManager.getConnection(new String("jdbc:mysql://localhost/myApplication"),

           new String("root"), new String(""));

jasperPrint = JasperFillManager.fillReport(jasperReport, params, conn);

My Connection object is not null! What is the problem here ?

Actually, my report was empty because there was no data returned from SQL query. Sorry.
