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.

From what I remember the difficulty was to setup
preemptive
authentication (by default XWiki does not send any challenged
especially when guess has the right to access) since it's quite a pain
in HTTPClient 4.3.
You can find a REST access example (with authentication) using
HTTPClient 4.3 on
https://github.com/xwiki/xwiki-commons/blob/master/xwiki-commons-core/xwiki…
.
The client is created in
https://github.com/xwiki/xwiki-commons/blob/master/xwiki-commons-core/xwiki…
.

I've tried could of times, but failed. All the examples are not with
httpClient 4.3.
I got error like 401, not authenticated, or 500,HTTP/1.1 500 Internal
