Nice catch Yes I appear to have made an error, I never associated the created credentials provider with the HTTP Client
Filed as JENA-475 (https://issues.apache.org/jira/browse/JENA-475) I will commit a fix ASAP and you should be able to pick up a 2.10.2-SNAPSHOT build in a few hours with the fix, if you can test with the snapshot and report if this resolves the issue that would be great. You can verify whether the fix has gone into the snapshots by looking at https://builds.apache.org/job/Jena__Development_Test/changes and seeing if there is a build listed where the commit messages mention JENA-475 Rob On 6/20/13 11:51 PM, "Arthur Vaïsse-Lesteven" <[email protected]> wrote: >Hi Rob, I'm in trouble with the basic authentication process ( I'm now >using ARQ 2.10.1 ) > > >In one hand the Queries work like this : >when we calls one of the 4 method execX of a queryExecution, the >QueryEngineHTTP calls makeHttpQuery, and after few steps this code line >is executed : > httpConnection.setRequestProperty("Authorization", "Basic "+y) ; >where y contains userName:password 64Bits encrypted. > >This make the http request header contains the Key, Value couple : >"Authorization" "Basic username:password". > >I'm OK with this. > >In the other hand, the update seem to handle Basic Authentication in a >different way. > >I used this code : > >UpdateRequest update = > UpdateFactory.create(queryString); >UpdateProcessRemoteForm exec = (UpdateProcessRemoteForm) >UpdateExecutionFactory.createRemoteForm(update, service); >exec.setAuthentication("[email protected]", "savaillon".toCharArray()); > >And I'm unable to retrieve the usename and the password. >Request contains following fields : >In headers : >content-lenght : 273 >content-type : application/x-www-form-urlencoded; charset=UTF-8 >host : localhost:8080 >conection : Keep-Alive >user-agent: Apache-HttpClient/4.2.3 (java 1.5) >In params : >update : my update >No attribute. > >I tried to follow in the ARQ library the path of my username and >password, and finally they transited to the applyAuthentication in HttpOp. > >This method create a CredentialsProvider and set the credentials username >and > password.
