Hi All, I have created a basic smart service plug-in and plug-in got deploy

Hi All,
I have created a basic smart service plug-in and plug-in got deployed successfully.
Am able to see the smart service under "MyCustomService" palette but running into two issues.
1) As mentioned at forum.appian.com/.../Custom_Smart_Service_Plug-ins.html, I kept custom icons into ../images
but still a default Icon is appearing for Smart service.
2) Unable to see the output variable, as documentation suggest "For an output, get<OutputName> methods are used without an explicit setter." I wrote get method In Java like @Name"Result" followed by method as "public int getResult()"
Attached is the plug-in. Need help to point out where am doing wrong?
