System.out.println("lurl pdf :"+urlCodedocPdf);
HttpClient client = new HttpClient();
// Create a method instance.
org.apache.commons.httpclient.methods.GetMethod method = new org.apache.commons.httpclient.methods.GetMethod(urlCodedocPdf);
// Provide custom retry handler is necessary
method.getParams().setParameter(org.apache.commons.httpclient.params.HttpMethodParams.RETRY_HANDLER,
new org.apache.commons.httpclient.DefaultHttpMethodRetryHandler(3, false));
try {
// Execute the method.
int statusCode = client.executeMethod(method);
if (statusCode != org.apache.commons.httpclient.HttpStatus.SC_OK) {
System.err.println("Method failed: " + method.getStatusLine());
}
// Read the response body.
response.setContentType ("application/pdf");
java.io.OutputStream os = response.getOutputStream();
try
{
InputStream ips = method.getResponseBodyAsStream();
java.io.InputStreamReader ipsr = new java.io.InputStreamReader(ips);
byte buffer[] = new byte[512 * 1024];
int nbLecture;
while ((nbLecture = ips.read(buffer)) != -1) {
os.write(buffer, 0, nbLecture);
}
}
catch (Exception e) {
e.printStackTrace();
} finally {
try {
os.close();
} catch (Exception e) {

Quelqu'un aurai-t-il déja rencontré ce type d'erreur ou une piste pour en trouvé l'origine.
Merci
