hi Thierry Sorry for late reply for ur post.Actually i have found the reason for the behaviour.The problem was in my code in matlab.Im really sorry for taking up ur time but without ur help i would not have found the problem in side matlab code.Im really thankful for your support.(i guess u can also cancel the bug created for the issue).
The problem was from the matlab i was passing invaild scheme name.But client was getting created with out any errors for eg.client("Protocol.HTTP").Thats the reason why i was getting a negative return from containAll(). Because of my in experience with the api i had feeling that it would give an error when i pass a invalid scheme name as string to the constructor for creating the client. Thanks a lot for helping me out.Any how im using the API so if i have any more doubts i will get back to u. regards Rashik.T ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2451691
