The clue is in the "static context" part of the error message.

The components on a form are all "Instance variables" - so they belong to an
instance of the form - one you create using the "new" keyword. The examples
use static variables and methods - these belong to the class itself. If you
declare a method (or "function" if you have a background in other languages)
as static, it can only use static variables - not instance variables. An
example may make this clearer...

public class AClass {
   private static int aStaticVariable
   private int anInstanceVariable
   
   public static void aStaticMethod() {
      aStaticVariable = 1; // this is OK
      anInstanceVariable = 1; // this will cause a compliler error
   }

   public void anInstanceMethod() {
      aStaticVariable = 1; // this is OK
      anInstanceVariable = 1; // this is OK
   }

}

It appears that you have tried to use jTextFieldMV.setText() inside a method
marked as static.
