---------------------------------------

i think 'index.jsp' would be a more standardized name

> Currently the ScriptedComponent analyzes the registered scripts and just falls back to a default script called jsp/start.jsp. This default selection should be extended such, that request selectors (see ComponentRequest.getSelectors()) contrubute to the script selection as follows:
>     - First apply all registered Script mappings of the ScriptedComponent
>     - Next use the request selectors to find a script below the scripted component node
>     - If the second step does not resolve a script (or if no selectors exist) just use the start.jsp script below the component node
> The second step needs some more explanations: The selectors of the request are joined with interleaving slashes to form a relative path. This path is appended to the path of the scripted component and the name of script is assumed to be start.jsp. If the path does not exist, trailing elements are just removed and such a longest match is tried to be found.
> Example: 
> (1) request for sample.html
> No selectors exist, the start.jsp script below the component is used
> (2) request for sample.image.gif
> Selector is a single entry list [ image ]. First the script image/start.jsp is checked, if that does not exist, the start.jsp is used.
> (3) request for sample.image.80x80.gif
> The selectors is a two-entry list [ image, 80x80 ]. The following scripts are tested in order: image/80x80/start.jsp, image/start.jsp, start.jsp.
