Hello Folks,
I am experiencing a problem with my dump servlet. The servlet simply echoes
back the content it recieved. The ServletInputStream comes up closed
(inputStream.available() returns 0). I do not understand what is consuming
the input. This does not happen on jetty 4.2.14. Please tell me what am I
doing wrong.
I have tried Tomcat 4.1.29 and 5.0.16 on Win 2K and JDK 1.4.2_01
TIA,
Dinesh
package servlet;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class upload extends HttpServlet {
public void doPost(HttpServletRequest request, HttpServletResponse
response) throws IOException, ServletException {
InputStream is = request.getInputStream();
OutputStream os = response.getOutputStream();
os.write(new String("Following data was
posted<br>").getBytes("US-ASCII"));
int chrsRead = 0;
while (is.available() > 0) {
int j = is.read();
StringBuffer sb = new StringBuffer();
switch (j) {
case '<': sb.append("<");break;
case '>': sb.append(">");break;
case '&': sb.append("&");break;
case '\n': sb.append("<br>");break;
default: sb.append((char)j);break;
}
for (int i = 0; i < sb.length(); i++)
os.write(sb.charAt(i));
chrsRead++;
}
os.write(new String("<br>Total chars read =
"+Integer.toString(chrsRead)).getBytes("US-ASCII"));
os.close();
os.flush();
}
}
