I have an applet application that reads a file located at the server.
Once I have establish the connection, I'm able read the contents of
the file with out any problems, until I have reached the end of the
file. Any new data that has been added to the file while the applet is
running I'm unable to read.
If I restart the applet again I can then see the data that was added.
Can someone please help me with this problem?
Thanks in advance!
Here is my code...
public void readFile(){
( new Thread() {
public void run() {
String line;
URL url = null;
try {
url = new URL( getCodeBase(), FileToRead );
}
catch( MalformedURLException e ) {
System.out.println( "Malformed URL " );
stop();
}
try {
InputStream in = url.openStream();
BufferedReader dis = new BufferedReader( new
InputStreamReader( in ) );
buf = new StringBuffer();
while( true ) {
while( ( line = dis.readLine() ) != null ) {
buf.append( line + "\n" );
}
// Load the file into the TextArea.
ta.append( buf.toString() );
Thread.currentThread().sleep( 5000 );
}
}
catch( IOException e ) {}
catch( InterruptedException ex ) {
System.out.println( "InterruptedException!" );
}
}
} ).start();
}
