I have an issue with my java application. I already read some questions here and none of them helped me. The issue is that I am trying to change text in my textbox which is defined this way:

public java.awt.TextField param1;

After that I want to load parametre from xml file (I am able to get parametre value), then set it in the textfield.

BP_evolution.gui.param1.setText(xsr.getText()); //xsr is XMLStreamReader
BP_evolution.gui.param1.repaint();

Where am I wrong with my code, please?

Thanks for the answer! Martin

do you get null pointer exception ??? – Madhawa Priyashantha Oct 05 '14 at 09:03
nope, application is running withou any errors/exceptions – Martin Plávek Oct 05 '14 at 09:05
Can you add more information to your question, e.g. what happens/ what happens not? It would also be helpful to know it `xsr.getText()` returns a non-empty string. – Stefan Freitag Oct 05 '14 at 10:30
Program is still running (till I quit it myslef) and what does not happen is that text is not shown in the TextBox. Thats all my problem.. xsr.getText() returns correct string (output control). – Martin Plávek Oct 05 '14 at 10:32

Why use AWT? See [this answer](http://stackoverflow.com/questions/6255106/java-gui-listeners-without-awt/6255978#6255978) for many good reasons to abandon AWT using components in favor of Swing. – Andrew Thompson Oct 06 '14 at 00:09
