Unable to append text from a separate class to a JTextArea - Java

this.addressLabel.setText("IP Address: " +address);
this.portLabel.setText("Port: " +Integer.toString(port));
}
public ChatBoxGUI() {

//note: this part isn't finished - but it doesn't need to be for that code to work
} catch (IOException e) {

}
}
I've tried to do research on the problem, and what I've found tells me that I have to use either invokeLater or invokeAndWait when running the code so that it runs in the EDT. And I have tried to implement this but it still doesn't seem to work:
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
chatBoxGUI.getTextArea().append("\nSearching for client connection. \nPort: " +serverSocket.getLocalPort());
}
});
Similar output to the terminal works completely fine, so it's definitely an issue with appending the text.
Any help would be appreciated, and thanks in advance.

You have multiple instances of the ChatBoxGUI class, so you are not updating the text area that is visible on the desktop.
So first you create the ChatBoxGUI class. Then when you click on a button you create the ServerClass. In the ServerClass you create a second instance of the ChatBoxGUI.
Don't create the second instance of the ChatBoxGUI class!!!
Instead, if you want to access variables in the ChatBoxGUI class then you need to:
pass a reference of the ChatBoxGUI class to the ServerClass
save this reference as an instance variable in the ServerClass
access this variable when you want to add text to the text area.

Without a more complete example, all I can do is link you to this question that has an answer for a similar issue.
Or you could try changing your approach from:
public javax.swing.JTextArea getTextArea()
{
return inputOutputTextArea;
}
To:
public void setTextArea(String textToAppend)
{
inputOutputTextArea.append(textToAppend);
}

Java Could not load or find main class

I'm using Netbeans to code a java program. I want this program to basically open an application, but have it all in one area.. (Windows already has it done.. but w/e).
When I open this program, as it says in the title, I get the error "Could not load or find main class" I have no idea why I'm getting this, as most of the other programs I have made don't have this issue.

In netbeans, I have something that looks like this:
"JavaApplication10"
"source packages"
"javaapplication10"
"javaapplication10.java"

Make sure your Main Class field is having correct value. In your case, it should be org.javaapplication10.javaapplication10

Updating a java jframe

I am trying to update the text in a jtextarea stored in a class I created with the netbeans GUI tool.
In my server class I have the following code....
window is the name of the object instance
Message message = (Message) in.readObject();
window.addText(message.getMessage());
The getMessage meathod works and I can output text to the console using this method.
This is the code I have in the GUI class (window) to update the textarea:
public void addText(String txt)
{
jTextArea1.append(txt);
jTextArea2.append(txt);
jTextArea1.updateUI();
jTextArea1.revalidate();
jTextArea1.validate();
jTextArea2.updateUI();
jTextArea2.revalidate();
jTextArea2.validate();
}
However this isn't updating... the method is defiantly receiving the string as I have tried outputting to the console from there (with no problem).
Do I need to refresh the window somehow?
