we will write some code to use in any Jasper report report

first, create a procedure

create or replace PROCEDURE GET_REPORT_F (p_file_name VARCHAR2 ,p_file_type VARCHAR2 ,p_paramter_name VARCHAR2 ,p_paramter_value VARCHAR2 )
IS
  v_blob                 BLOB;
  v_file_name            VARCHAR2 (25) := p_file_name||'.'||p_file_type;
  v_vcContentDisposition VARCHAR2 (25)  := 'inline';

  v_hostname   VARCHAR2(30) := 'localhost'; -- your hostname, eg: localhost
  v_port       NUMBER       :=   '8081'; -- port for your JasperReports Server, eg: 8081
  v_username   VARCHAR2(50) := 'jasperadmin'; -- jasperreports server username 
  v_password   VARCHAR2(50) := 'jasperadmin'; -- jaspereports server password
  v_jasper_string VARCHAR2(30) := v_username || ';' || v_password;
   v_login_url  VARCHAR2(100) := 
    'http://' || v_hostname || ':' || v_port || '/jasperserver/rest/login';
  -- modify below URL before use!
  -- you should modify the line below; change /Pretius/ to your own name
  -- before you add a line try your URL in a web browser
  v_report_url VARCHAR2(100) := 
    'http://' || v_hostname || ':' || v_port || '/jasperserver/rest_v2/reports/reports/ALI/' || v_file_name;
BEGIN
  -- log into jasper server
  v_blob := apex_web_service.make_rest_request_b(
    p_url => v_login_url,
    p_http_method => 'GET',
    p_parm_name => apex_util.string_to_table('j_username;j_password',';'),
    p_parm_value => apex_util.string_to_table(v_jasper_string,';')
  );
  -- download file
  v_blob := apex_web_service.make_rest_request_b(
    p_url => v_report_url,
    p_http_method => 'GET',
    p_parm_name => apex_util.string_to_table(p_paramter_name,';'),
    p_parm_value => apex_util.string_to_table(p_paramter_value,';')
  );
 owa_util.mime_header('application/PDF',false);
  htp.p('Content-Length: ' || dbms_lob.getlength(v_blob)); 
  owa_util.http_header_close;  
  wpg_docload.download_file(v_blob);
EXCEPTION
  WHEN OTHERS THEN
    RAISE;
END;

second, Create 4 Application Item

third, make report on emp table

create a link on a column to pass the parameter

create a page to display the report in an iframe

create process [pefore header ]

DECLARE
    l_url varchar2(2000);
    l_app number := v('APP_ID');
    l_session number := v('APP_SESSION');
    V_FILE_NAME varchar2(200) :=  :APP_FILE_NAME;
    V_FILE_TYPE varchar2(200) := :APP_FILE_TYPE;
    V_PARM_NAME varchar2(200) := :APP_PARM_NAME;
    V_PARM_VALUE varchar2(200) := :APP_PARM_VALUE;

BEGIN

    :P2_URL2   := APEX_UTIL.PREPARE_URL(
          p_url => 'f?p=' || l_app || ':0:'||l_session||':APPLICATION_PROCESS=REPORT_PROCESS_F:NO::APP_FILE_NAME,APP_FILE_TYPE,APP_PARM_NAME,APP_PARM_VALUE:'||V_FILE_NAME||',' ||V_FILE_TYPE||','||V_PARM_NAME||','||V_PARM_VALUE  );

END;

create a region for iframe

<p align="center">
<iframe src="&P2_URL2." width="99%" height="1000">
</iframe>
</p>

you will get a report

thanks
