  - execute
```
public R execute()
```
    This method calls the execute method of a .WebTreatment instance. One of the aim of this mechanism is to centralize the exception catching and also to avoid redundant coding around web exceptions. If the lowest role access is defined, the user must verify it. If the user isn't authenticated, a 401 HTTP code is returned. If a problem occurs when processing the request, a 503 HTTP code is returned.
    
    Returns:
    
    the value computed by the specified web treatment.
