Not able to execute rules using RemoteAPI in BRMS/BPMS 6

Issue

We need to execute rules, processes from a remote application, for this we are using Remote Rest API,as shown below:
I downloaded your sample code which seems to work fine for tasks but not for rules.

RemoteRestRuntimeFactory factory = new RemoteRestRuntimeFactory(DEPLOYMENT_ID, url, USER,PASSWORD);
KieSession ksession=factory.newRuntimeEngine().getKieSession();
ksession.fireAllRules();
ksession.startProcess("Project1.TestProcess");

With this code we are able to start process,but rules are executed.
