I would like the input stream read to block instead of reading end of stream (-1). Is there a way to configure the stream to do this? Here's my Servlet code:
PrintWriter out = response.getWriter();
BufferedReader in = request.getReader();
try {
String line;
int loop = 0;
while (loop < 20) {
line = in.readLine();
lgr.log(Level.INFO, line);
out.println("<" + loop + "html>");
Thread.sleep(1000);
loop++;
//
}
} catch (InterruptedException ex) {
lgr.log(Level.SEVERE, null, ex);
} finally {
out.close();
}
Here's my Midlet code:
private HttpConnection conn;
InputStream is;
OutputStream os;
private boolean exit = false;
public void run() {
String url = "http://localhost:8080/WebApplication2/NewServlet";
try {
conn =
(HttpConnection) Connector.open(url);
is = conn.openInputStream();
os = conn.openOutputStream();
StringBuffer sb = new StringBuffer();
int c;
while (!exit) {
os.write("<html>\n".getBytes());
while ((c = is.read()) != -1) {
sb.append((char) c);
}
System.out.println(sb.toString());
sb.delete(0, sb.length() - 1);
try {
Thread.sleep(1000);
} catch (InterruptedException ex) {
ex.printStackTrace();
}
}
os.close();
is.close();
conn.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
I've tried InputStream.read, but it doesn't block either, it returns -1 as well.
I'm trying to keep the I/O streams on either side alive.
I want the servlet to wait for input, process the input, then send back a response.
In the code above it should do this 20 times.
thanks for any help
