Not Displying to the Text Area

    I am trying to out put to a TextArea but it is not working. I believe I am missing something. I am using NetBeans and it will run on the output box of NetBeans but not in the GUI (TextArea). Any ideas?

    if you replace for example
    System.out.print("Report of wages to date:" + newline + newline);

    with

    jTextArea1.setText("Report of wages to date:" + newline + newline);

    you will have the desired.
