Paul,
there's more than one thing wrong with that code:
1. the import of Mysource is unnecessary since both classes belong to the
same package. Whether this causes any harm I can't say.
2. in BusLogicDataClass method getTxtFields you need a type declaration in
front of your variables:
      String name = txtfldName.getText();
3. I am not sure what you are trying to achieve with the class
BusLogicDataClass. Since you declared all those variables private, they can
only be seen within that class. And since getTxtFields() does not return
anything, you can't get at them from outside by calling getTxtFields
either. If you are trying to deliver those variables to UIDataClass, then
you will have to write a setter/getter method for each value, or return
them all concatenated in one string (or as a string array) via return and
parse that string in UIDataClass.
