Dear All

I m a new user of java.

plz help me out 2 solve my problem.

1 class = dbconnection
2 class = util
3 class = company
4 class = login

i ve connected database with dbconnection in login form using
dbconnection conn = new dbconnection();

then userid is asked. When i enter my login it passes value to util class
util u = new util(); // this is initialized at top.

public String setValue(String str)
{ String myVal
myVal = str;
return myVal;

when i m trying to print that value i is showing user id.

I ve a button on login form called "Company".
I ve inititlized util object at the top.

util abc = new util();

i want to get the value that i ve assigned in my login form using setValue() method.

But when ever i m getting value from util class it shows null value;
Plz tell where i m wrong?


Love is GOD and GOD is Love.

If you are attempting to perform a util.getValue() to fetch the value after it is set, you will not get a value since you initialized the myVal String within your util.setValue(String str) method. In order to retrieve this value, you will have to create a class member that you would populate in the setValue(String str) method and retrieve via the getValue() method
