hi
this is my service client code

include "scenario/scenario.h"
include

int main(int argc, char **argv) {
ros::init(argc, argv, "remote");
ros::NodeHandle n;
ros::ServiceClient client = n.serviceClientscenario::scenario("stringa");
ros::Rate loop_rate(0.5);
while (ros::ok()){
scenario::scenario srv;
srv.request.pc="hello word";
if (client.call(srv)){
if((unsigned)srv.response.rasp[0]!=255)
ROS_INFO("%s", srv.response.rasp);
} else
{
ROS_ERROR("Failed to call service scenario");
return 1;
}
ros::spinOnce();
loop_rate.sleep();
}
return 0;
}

Check whether service is getting started correctly using rosservice list command and try calling service from terminal, if it works fine then service is working fine but the way ur calling ur code is not correct.

i typed rosservice list /local/get_loggers /local/set_logger_level /rosout/get_loggers /rosout/set_logger_level /stringa and then rosservice type stringa ERROR: Unable to communicate with service [/stringa], address [rosrpc://nicolo-laptop:40626]

If this is the case then ur service declaration might have some problem. Name of the service is same as package name so try changing name of the service from scenario to something else..it might resolve the problem..
