Changing connection at runtime

Question

How can I change the db connection at
runtime in a bc4j and jsp application:
I start from a standard db connection
read from the app property file and then
I read from the database connection information and I have to reconnect.
Thank's in advance

If you want to change connections, you first have to logout. Besides the logon_screen builtin does not change the connection, but it only sets several application properties.
In the Forms Help there is an example how to use the logon_screen. It basically comes to the next pl/sql code:
declare
MyUsername VARCHAR2(40);
MyPassword VARCHAR2(40);
MyConnect VARCHAR2(40);
begin
logon_screen;
MyUsername := Get_Application_Property(USERNAME);
MyPassword := Get_Application_Property(PASSWORD);
MyConnect := Get_Application_Property(CONNECT_STRING);
logout;
if MyConnect is not null then
logon(MyUsername,MyPassword| |'@'| |MyConnect);
else
logon(MyUsername,MyPassword);
end if;
end;
null
