public class JasperLoader extends com.sun.portal.providers.jsp.jasper3.jasper.runtime.JspLoader (Code)
This is a class loader that loads JSP files as though they were Java classes. It calls the compiler to compile the JSP file into a servlet and then loads the generated class. This code is quite fragile and needs careful treatment/handling/revisiting. I know this doesn't work very well right now for: (a) inner classes (b) does not work at all for tag handlers that have inner classes; but that is likely to change with the new JSP PR2 spec.
