Cannot enter data to a textarea control(desktop swing application)

Hi,

We have identified an element on our swing application which is actually a text field for entering username. The element identification is shown as below 

Control nameAnduserTextField = process.find(TestProcess.class, new ProcessPattern(){{
    ProcessName = "jp2launcher";
    Index = 2;
}}).find(TopLevelWindow.class, new AWTPattern(){{
    JavaFullClassName = "com.techrx.security.dialog.SplashLogin";
    AWTComponentAccessibleName = "login page";
    AWTComponentIndex = -1;
}}).find(Control.class, new AWTPattern(){{
    JavaFullClassName = "javax.swing.JRootPane";
    AWTComponentAccessibleName = "";
    AWTComponentIndex = 0;
}}).find(Control.class, new AWTPattern(){{
    AWTComponentName = "null.layeredPane";
}}).find(Control.class, new AWTPattern(){{
    AWTComponentName = "null.contentPane";
}}).find(Control.class, new AWTPattern(){{
    AWTComponentName = "Username";
}});

It says element is identified as control and I have type casted is as shown below with a text field.

 TextEdit nameAnduserTextField =(TextEdit) process.find(TestProcess.class, new ProcessPattern(){{
        ProcessName = "*";
    }}).find(TextEdit.class, new AWTPattern(){{
        AWTComponentName = "Username";
    }});
nameAndRdacTextField.setwText("1234567");

However, we get the error as the element is not identified with an invalid pattern. Can someone let us know what has to be done for this?
