How-to read a text file and display it in a Text-area ...
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,
Re: How-to read a text file and display it in a Text-area ...
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:
while ((tmp = br.readLine()) != null)
TEXT += tmp;
out.println("<td><textarea rows=11 cols=131>" + TEXT + "\n");
That should do it.
