Java.lang.NullPointerException by parsing a string into an int

Question

Hi,
I am trying to call a method with the first argument as an int.
I have successfully tested to call it with normal int, it works.
The problem is that the int i need to send has first to be casted from a string ( a jtext field basically)
what i do is :
destAddrInt = (int)Integer.parseInt(destAddr.trim());
this.sendCommand(destAddrInt , cmdShortArray);but what ever i try it will not work, i always get the java.lang.NullPointerException.
i have even tried to copy the value into an int:
destAddrInt = (int)Integer.parseInt(destAddr.trim());
int dum;
dum = destAddrInt;
this.sendCommand(dum, cmdShortArray);What can I do?
Thanks for your help!

Why do you need to typecast the int again into an integer after you have parsed it?This was actually my last try (I did several tries to find a solution)!
Ok, know I did follow the stack trace with ex.printStackTrace(); and found that the exception was afterward (some uninitialized Set).
And now it work, and of course even with
Integer.parseInt(destAddr.trim())
If I had to guess, I'd say it's in the call to the trim() method on destAddr.Trim has not be a problem).
