writing UI content to a file on a server - textarea

Question

I've got a pop-up textarea, where the user writes some lengthy comments. I would like to store the content of the textarea to a file on the server on "submit". What is the best way to do it and how?
THanks,

This would be very easy to do. The text could be just a string or stringBuffer for size and formatting, then just pass that to your java code and use file operations to write to a file.
This is some GWT code, but it's still Ajax, so it will be similar. Get a handler for an event to capture the button submittal, then get the text in the text area.
textArea.addChangeHandler(new ChangeHandler() {
public void onChange(ChangeEvent changeEvent) {
String text = textArea.getText();
}
});
The passing off mechanism I don't know because you don't show any code, but I just created a file of filenames, line by line by reading filenamesout of a list of files with this:
private void writeFilesListToFile(List<File> filesList) {
for(File file : filesList){
String fileName = file.getName();
appendToFile(fileName);
}
}
private void appendToFile(String text){
try {
BufferedWriter out = new BufferedWriter(new FileWriter<file path andfile name>));
out.write(text);
out.newLine();
out.close();
} catch (IOException e) {
System.out.println("Error appending file with filename: " + text);
}
}
You could do something similar, only write out the few lines you got from the textarea. Without more to go on I can't really get more specific.
HTH,
