This interface should be implemented by plugins that want to support JSP
source level debugging, but do not support JSR 45.
The prerequisite for the JSP debugging support (without JSR 45) is the support
for finding a generated servlet, represented by the FindJSPServlet interface.
Creates a servlet <-> JSP mapping for a given JSP. May be null if the server is not running
or the page has not been compiled. Also may be null if the server plugin does not support
creation of the line mapping information.
module - web module in which the JSP is located.
jspResourcePath - the path of the JSP for which the mapping is requested, e.g.
"pages/login.jsp". Never starts with a '/'.
