if("Open".equals(command)){

String filename = tfFilename.getText();
try{

BufferedReader inputStream = null;
inputStream = new BufferedReader(new FileReader(filename));

String tmpStr = "";

if (inputStream != null) {
while((line = inputStream.readLine()) != null) {

I think it is better to use append method not setText

textArea.append("the message to be appended");
