Hello,
The answer of your second question is very simple.
for example Your Jtextarea calls jtext.
So You have to do:

try
{

BufferedWriter out
= new BufferedWriter(new OutputStreamWriter(text.txt));
out.write(jtext.getText());



}// --> try

Now you only have to catch the right exceptions (for example IOException)

Your first problem, I don't understand, what you mean, so, ....

Best regards
