Java Development Tools

Hi everyone , i am using jdeveloper 11.1.2.3.0

and my problem is

i have a form with some output texts

i create a simple java been with request scope name as "SetValBeen" and try to set value of all output texts in a method name as "setValMathod"

now i create an other been  name as "Mainbeen" and create a method name as "exeCode" in Mainbeen i call   "exeCode " method by hitting on button

now inside exeCode method i create an obect of SetValBeen class and execute setValMathod

the code is like this

exeCode(){

SetValBeen svb =new SetValBeen();

//calling method to set output text values

svb.setValMathod();

}

all the code is executed properly but at run time output text value not set

i also refresh the output text by hitting on button

kindly reply what should i do ??

Thanks
