Using roslibjs and one simple action server Errors [closed]
Hello, using roslibjs to connect with rosbridge, with the objective of sending a goal to a simple action server, I am getting this error:
[INFO] [WallTime: 1423829560.345222] Client connected. 1 clients total.
[ERROR] [WallTime: 1423829560.496586] [Client 0] [id: advertise:/control/goal:1] advertise: Unable to load the manifest for package gamma. Caused by: gamma
[INFO] [WallTime: 1423829560.770795] [Client 0] Subscribed to /control/status
[ERROR] [WallTime: 1423829560.780198] [Client 0] [id: subscribe:/control/feedback:4] subscribe: Unable to load the manifest for package gamma. Caused by: gamma
[ERROR] [WallTime: 1423829560.790271] [Client 0] [id: subscribe:/control/result:5] subscribe: Unable to load the manifest for package gamma. Caused by: gamma
I think that the package.xml file is missing but i don't know what is the specific content of this file for this case (to specify the goal, result and feedback).
So where can I place the package and what does it contain?
Maybe its related to one file error, i guided my self by the tutorial and the webpage says error at the back end, maybe I am doing something wrong, i paste my file here:
