But when I invoke this in logs it gives following error...
Exception occured when binding was invoked.
Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'AppsService' failed due to: Apps Context Error.
Error occurred while setting up Apps Context.
Context parameters should be valid.
Contact oracle support if error is not fixable.
