It looks all the issue is due to The preemptive authentication. I got a
successfull sample.
Here is my code
HttpHost target = new HttpHost("www.chinafgr.com",
8000, "http");
// Create AuthCache instance
AuthCache authCache = new BasicAuthCache();
// Generate BASIC scheme object and add it to the local
// auth cache
BasicScheme basicAuth = new BasicScheme();
authCache.put(target, basicAuth);
// Add AuthCache to the execution context
HttpClientContext localContext =
HttpClientContext.create();
localContext.setAuthCache(authCache);
response =
httpclient.execute(target,putMethod,localContext);
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
I think it's better the mention that need peemptive anuthentication in the
doc.
thanks,Thamas.
