```
public static java.lang.String toJson(java.lang.Object input)
```
    Uses Google Gson (https://code.google.com/p/google-gson/) to convert to JSON
    
    Parameters:
    
    input - the object to be converted to JSON
    
    Returns:
    
    the JSON string of the object
  - getNextPathPart
```
public static java.lang.String getNextPathPart(java.lang.String path,
                                               java.lang.String lastPart)
                                        throws javax.servlet.ServletException
```
    Given a requestUri path, find the next uri "fragment" after the "/lastPart/" one. E.g. given url "/test/abc/travel", and lastPart "abc", this will return "travel". Given lastPart "test" will return "abc". This could be done better using a URITemplate (as RFC6570)
    
    Parameters:
    
    path - the RequestURI to search usually done by calling request.getRequestUri().
    
    lastPart - the previousPart of the path to search after.
    
    Returns:
    
    the next part of the path.
    
    Throws:
    
    javax.servlet.ServletException - if path does not contain lastPart
