Hello,
I was hoping that someone could give me some help with the following
problem. I have a servlet that needs to respond to requests from
URLs and other servlets. Servlet to servlet link works fine.
The problem is that there does not seem to be a way for a URL
connection
to tell when the servlet connection has gone away, so the URL "client"
will hang forever.
Here is a code snippet from the client that has the URL connection
to the servlet:
HttpURLConnection dataCon = null;
// url_ is the URL to the servlet
dataCon = (HttpURLConnection) url_.openConnection();
// Set up the connection to be POST, allow output, and set the session
// cookie
dataCon.setDoOutput(true);
dataCon.setRequestMethod("POST");
if (sessionCookie_ != null) {
dataCon.setRequestProperty("Cookie", sessionCookie_);
}
OutputStream out = dataCon.getOutputStream();
...write the output
out.flush();
out.close();
InputStream in = null;
in = dataCon.getInputStream();
int numBytes = 0;
try
{
do
{
numBytes = in.available();
if(numBytes < 1)
{
try
{
Thread.sleep(1000*2);
}
catch(InterruptedException ie)
{
}
}
}while(numBytes<1);
}
catch(IOException ioe)
{
...connection gone
.
.
return;
}
...read the input
The in.available() never throws an exception if the web server
times out and breaks the connection.
Is there some way to tell if the servlet/web server has disconnected?
Thanks.
