Unable to access a Remote Object

Hello Everyone,
As mentioned in the subject, i'm unable to hit my Remote Object from the Flex UI. The Remote Object is available in a Web project having been properly configured in the remoting-config.xml , deployed in an EAR and run on Websphere Application Server. Inspite of the Remote Object being available, i get the following error. Any suggestions from you is welcome.
