How to call a report from a form

Question

I've created a report with Oracle Reports 10g and saved as MYREPORT.JSP and as MYREPORT.RDF
Than I've created a form and a button with a trigger when-button-pressed with this code:
declare
     repid REPORT_OBJECT;
     v_rep VARCHAR2(100);
     rep_status VARCHAR2(20);
begin
     repid := FIND_REPORT_OBJECT('D:\ORAFORMS\MYREPORT.JSP');
     v_rep := RUN_REPORT_OBJECT(repid);          
end;
If I run the form and then click the button created, instead of running the report, I get this message:
FRM-41219: Cannot find report: invalid ID
I use local OC4J Instance
Can you help me?
Thanks!

I've started up the server rwserver SERVER=myserver as you've told me (and this has been useful 'cause I didn't know).
Then I've added an item under the Reports section in the Object Navigato called MYREPORT where filename is D:\ORAFORMS\INIZIO_CORSO_REPORT.rdf (that is my report)
Then I've put int the trigger of the button the block:
DECLARE
v_repid REPORT_OBJECT;
v_rep VARCHAR2(100);
v_rep_status VARCHAR2(100);
v_param VARCHAR2(200) := NULL;
v_valor VARCHAR2(200);
v_url VARCHAR2(2000);
v_repserver varchar2(20) := 'myserver';
v_report varchar2(100) := 'D:\ORAFORM\INIZIO_CORSO_REPORT.RDF';
v_PARAMETRO varchar2(100) := null;
BEGIN
v_repid := FIND_REPORT_OBJECT('MYREPORT'); -- report is an element from object navigator report
SET_REPORT_OBJECT_PROPERTY(v_repid, REPORT_FILENAME, v_report);
SET_REPORT_OBJECT_PROPERTY(v_repid, REPORT_EXECUTION_MODE, BATCH);
SET_REPORT_OBJECT_PROPERTY(v_repid, REPORT_COMM_MODE, SYNCHRONOUS);
SET_REPORT_OBJECT_PROPERTY(v_repid, REPORT_DESTYPE, cache);
SET_REPORT_OBJECT_PROPERTY(v_repid, REPORT_DESFORMAT, 'pdf' );
SET_REPORT_OBJECT_PROPERTY(v_repid, REPORT_DESNAME, v_report);
SET_REPORT_OBJECT_PROPERTY(v_repid, REPORT_SERVER, v_repserver);
SET_REPORT_OBJECT_PROPERTY(v_repid, REPORT_OTHER, 'paramform=no '||v_PARAMETRO);
v_rep := RUN_REPORT_OBJECT(v_repid);
v_rep_status := REPORT_OBJECT_STATUS(v_rep);
WHILE v_rep_status IN ('RUNNING','OPENING_REPORT','ENQUEUED') LOOP
v_rep_status := REPORT_OBJECT_STATUS(v_rep);
END LOOP;
IF v_rep_status = 'FINISHED' THEN
message(v_rep);
message(v_rep);
WEB.SHOW_DOCUMENT(v_url||'/reports/rwservlet/getjobid'||
SUBSTR(v_rep, INSTR(v_rep,'_', -1)+1)||'?'||'server='||v_repserver, '_blank');
END IF;
END;
At this point I've run rwserver SERVER=myserver but when I try to click on the button, after a while I get the new message:
FRM-41214: Unable to run report
