Java Development Tools

Hi every one i am using jdeveloper 12.2.1.1.0

and my use case is i perform pragmatically login and

in been (name Login and scope session) i set two session scope variables uname and upw

private void setGlobal(String uname,String upw){

//to set the value of user name and password

this.setEL("#{sessionScope.uname}", uname);

this.setEL("#{sessionScope.upw}", upw);

}

now i need to access this uname variable in view object to set the bind variable value

actually i am trying to fetch data according to login user , so for that i have to pass the user name in query

how can i do this

thanks
