Carsten Ziegeler commented on SLING-2094:
-----------------------------------------

I think propagating the exception to the top of the jsp engine is fine - this 
avoids cluttering too much in the jasper code.
I think, if we restrict the errorPage to a jsp page, you should be able to get 
the jsp page by path - if you look at the method 
JspScriptEngineFactory#getJspWrapperAdapter: the jsps is created/fetched by 
resource path, so using this approach, it should be easy to call any other jsp 
from within the jsp scripting without going through the resource resolver or 
the script resolver.

> Adding support to call a sling resource for JSP page exception handler  <%@ 
> page errorPage ... %>

> At the moment the JSP page exception handler (<%@ page errorPage ... %>) is 
> not supported as the jsp engine can't resolve the path to the jsp if  this is 
> a repository resource.
