Forms :: Secure Web.show-document() - Getting Error?

am trying to use secure call to reports from forms using the frmrwinteg.jar javabean.

when i set the implementation class of the javabean area i still have the error FRM-13008 can't find javabean with name..,but i ignore it as i read at the whitepaper downloaded from OTN. and follow all instructions add to java directory,, add to formsweb,, add parameter to basejini.htm

each time i call the report i have been asked to connect and when i run the form my username and password are written to the consol and i still can see them at the html code when call parameter form, my code is

DECLARE

rep_url varchar2(2000);

BEGIN
rep_url:='http://office_server:8889/reports/rwservlet?server=repserver10&report=d:mm-J.JSP
&desformat=htmlcss&destype=CACHE¶mform=yes&userid=';
set_custom_property('block3.userid_bean',1,'WRITE_LOGOUTPUT','true');

[code]...

and this is what is written to the consol

FrmReportsInteg1: Debugging true
FrmReportsInteg1: Adding new userid string "xx/xx@xxxxx"
FrmReportsInteg1: ADD_REPORTS_CONNECT: xx/xx@xxxxx
FrmReportsInteg1: Setting cookie path to /reports/TEST/

[code]/....

i DON'T KNOW WHERE IS THE ERROR THAT MAKE THIS NOT WORK.
