I have the code working to actually bring back the data that I need.
However, in the process of actually getting it working, I noticed that if
the authentication had any issues (like acct locked out, or unauthorized)
the program would go into an infinite loop of trying to authenticate. So, I
am trying to fix that before I take this code to production.
The code is as follows:
main(){
try {
HttpClient client = new HttpClient();
List authPrefs = new ArrayList(1);
authPrefs.add(AuthPolicy.DIGEST);
client.getParams().setParameter(AuthPolicy.AUTH_SCHEME_PRIORITY,
authPrefs);
client.getParams().setParameter(
CredentialsProvider.PROVIDER, new
ConsoleAuthPrompter());
PostMethod gm = new
PostMethod("http://~~servername~~/Maps/MapsStaging/PlatPDFHandler.ashx?pid=3&isbw=0";);
gm.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
myretryhandler);
int status = client.executeMethod(gm);
System.out.println("Response Status: "+ status);
//String result = gm.getResponseBodyAsString();
//System.out.println(result);
InputStream iStream = gm.getResponseBodyAsStream();
DataOutputStream oStream = new
DataOutputStream(System.out);
//FileInputStream iStream = new
FileInputStream(fullFilenameAndPath.toString());
byte[] buffer = new byte[1024];
int bytesRead = iStream.read(buffer);
while(bytesRead > -1)
{
oStream.write(buffer, 0, bytesRead);
bytesRead = iStream.read(buffer);
//System.out.println("bytesRead="+bytesRead);
}
oStream.flush();
oStream.close();
//System.out.println("after stream = "+iStream.read());
iStream.close();
gm.releaseConnection();
} catch (IOException e) {
e.printStackTrace();
}
}
HttpMethodRetryHandler myretryhandler = new
HttpMethodRetryHandler() {
public boolean retryMethod(
final HttpMethod method,
final IOException exception,
int executionCount) {
if (executionCount >= 5) {
// Do not retry if over max retry count
return false;
}
if (exception instanceof NoHttpResponseException) {
// Retry if the server dropped connection on us
return true;
}
if (!method.isRequestSent()) {
// Retry if the request has not been sent fully or
// if it's OK to retry methods that have been sent
return true;
}
// otherwise do not retry
return false;
}
};
I have added the HttpMethodRetryHandler as indicated on the HttpClient main
page, however it doesn't seem to be helping in any way.
Any help with this last remaining issue, would be GREATLY appreciated.
Thanks,
PCable
