PUT and basic authentication
Hi,
I have a simple PUT request app working.
Now I want to add Basic Authentication to it. With a GET sample app it
works. But with PUT I get the following error.
27.01.2005 09:15:09
org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme
INFO: basic authentication scheme selected

put.setRequestEntity(entity);
client.getHttpConnectionManager().
getParams().setConnectionTimeout(5000);
int status = client.executeMethod(put);
if (status == HttpStatus.SC_OK) {
System.out.println("Upload complete, response=" +
put.getResponseBodyAsString());
} else {

}
Can anyone help?

Mocking httpclient for unit testing...
Hi,
I'm trying to wrtie a unit test around a module that uses httpclient.
Ideally I'd like to mock up the actual connection out of my system since
this is not the functionaliy I want to test.
I've seen other approaches with the basic socket library where
connections and socket classes were mocked and supplied directly to the
class under test. That way the mock implementation doesn't make any
connection at all. But I don't see how to do this with httpclient.
One option would be to mock the complete Httpclient and GetMethod that I
use.
What approaches do people use for this?
The alternative is that I need to start up a webserver as part of my
test suite, and get httpClient to connect to that? But this seems a
little messy.
Cheers,
Keith

Try method.setDoAuthentication(false), that should stop the HttpClient
from automatically handling the 401 response, while it still allows for
preemptive authentication.
hope that helps,

Roland,
Thank you. Yes that works.
One more question: If I supply the wrong credentials, I get again the
"ProtocolException: unbuffered entity enclosing request can not be repeated"
which is not very helpful. Can I change something so that I get a server
response "Not authorized" or the like?

Hello Michael,
you have to enable preemptive authentication.
Otherwise, HttpClient will send the request without
basic auth, get an error reply, and cannot retry with
basic auth because the message body has already
been sent. See
HttpClientParams.setAuthenticationPreemptive(...)
cheers,
Roland
