First thing: button should be link to page for example P99
Next thing: You can pass some values with thatbutton and after that zou can call different reports
Important thing is to make new proces in page 99 and execute them before header...
Process shoud have procedure something likde this:
xlib_jasperreports.set_report_url('http://localhost:8080/JasperReportsIntegration/report');
-- construct addional parameter list
l_additional_parameters := '&p_parameter_1=' || apex_util.url_encode(:P99_partameter_1);
l_additional_parameters := l_additional_parameters || '&p_parameter2=' || apex_util.url_encode(:P99_parameter2);
-- call the report and pass parameters
test3.xlib_jasperreports.show_report (p_rep_name => l_rep_name,---conditional dynamicly change name of report
p_rep_format => xlib_jasperreports.c_rep_format_pdf,
p_data_source => 'default',
p_out_filename => l_rep_name||'.pdf',
p_additional_params => l_additional_parameters);
///All your reports should be under path: *WINDOWS" C: or any other location .....Apache Software Foundation\TomcatX\webapps\JasperReportsIntegration\WEB-INF\reports\rep1 or rep2...etc
