How-to read a text file and display it in a Text-area ...

[Gabriele]

Hi all, I have a servlet (written in java) that should read a TEXT file, put
all the content of the text file in a variable and then display it in the
text area like this:
<td><textarea rows=\"11\" cols=\"131\">" + TEXT + "</textarea></td>\n"

Now the problem is that I can only read a line from the text file:

FileReader fr = new FileReader(doc_path + doc_name + doc_ext);
BufferedReader myInput = new BufferedReader(fr);

TEXT = myInput.readLine();


HOW could I display the whole TEXT of the file ?

Thank in advance,
Gabriele

Hi Gabriele,

the BufferedReader.readLine() method will return a line from the file. When
the end of the input has been reached, it returns a null. To read the whole
file, use the following loop:


String tmp;
while ((tmp = br.readLine()) != null)
{
TEXT += tmp;
}
out.println("<td><textarea rows=11 cols=131>" + TEXT + "\n");

That should do it.
