Konrad Windszus commented on SLING-6793:
----------------------------------------

[~cziegeler] Although it is pretty easy to get this in Java, there is no 
[BindingsValuesProvider|https://github.com/apache/sling-org-apache-sling-scripting-api/blob/master/src/main/java/org/apache/sling/scripting/api/BindingsValuesProvider.java]
 for the XSSApi (for any script engine). So what is your recommended way now to 
get the XSSApi in JSP?

>
> The XSSAPI defines two methods:
>     XSSAPI getRequestSpecificAPI(SlingHttpServletRequest request);
>     XSSAPI getResourceResolverSpecificAPI(ResourceResolver resourceResolver);
> which imply that there is some user specific xss checking for validating 
> hrefs. However user specific xss validation is neither implemented nor does 
> it make sense.
> Therefore we should remove these methods
> At the same time we should remove the XSSAPIAdapterFactory as this is abusing 
> the adapter pattern. Getting an XSSAPI service in Java or JSP is easy and 
> there is no need to use the adapter pattern here.
