Hi,
I have a problem with synchronization of the java commands.
In the Before Parammeter Form trigger, I have:
function BeforePForm return boolean is
rt ORA_JAVA.JOBJECT;
proc ORA_JAVA.JOBJECT;
v_txt varchar2(32000);
i integer := 0;
v_cd_modulo int;
v_arqlog text_io.file_type;
cursor c_evento is
select codigo,
nome
from
(select e.cd_evento || e.cd_edicao codigo
,nm_evento nome
from grh_ev_evento e
where e.CD_GRUPO in (select cd_grupo
from grh_ev_adm
where cd_usuario = (select cd_usuario
from usuario
where login_usuario = :AUTHID)))
order by substr(nome, 11);
begin
-- Create the context for logged user
if instr(upper(nvl(:AUTHID,'RWCLIENT')),'RWCLIENT') > 0 then
:AUTHID := :SSO_USUARIO;
end if ;
TCEENV.SET_TCEENV(:AUTHID);
if PK_SCA.SCA_GET_USER_RIGHTS(:sca_module_name, :AUTHID) IS NULL then
srw.message(100, 'Access denided!');
return (FALSE);
end if;
-- Create file in Report Server (UNIX)
v_txt := '<BR>' || htf.formSelectOpen('P_EV_EDICAO', 'Evento: ');
:p_file := '/u03/SCAWEB/repout/' || :sca_module_name || '_' ||
pk_sca.sca_encrypt(:AUTHID || to_char(systimestamp, 'ss.ff'));
v_arqlog := text_io.fopen (:p_file, 'A');
text_io.put_line (v_arqlog, v_txt);
for reg in c_evento loop
i := i + 1;
if i = 1 then
v_txt := '<OPTION SELECTED VALUE="' || reg.codigo || '">' || reg.nome;
else
v_txt := '<OPTION VALUE="' || reg.codigo || '">' || reg.nome;
end if;
text_io.put_line (v_arqlog, v_txt);
end loop;
v_txt := '</SELECT></CENTER></form></BODY> </HTML>';
text_io.put_line (v_arqlog, v_txt);
text_io.fclose (v_arqlog);
SRW.SET_AFTER_FORM_HTML(SRW.FILE_ESCAPE, :p_file);
rt := RUNTIME.GetRuntime();
proc := RUNTIME.exec(rt,'rm ' || :p_file);
return (TRUE);
end;
The problem is that there isn't a "synchronize" command, and the
RUNTIME.exec(rt,'rm ' || :p_file) don't works (it does nothing) because
the SRW.SET_AFTER_FORM_HTML has a large delay and the following
command is ignored.
How can I solve it?
thanks,
