Package org.apache.jasper.runtime
Class JspRuntimeLibrary
java.lang.Object
org.apache.jasper.runtime.JspRuntimeLibrary
Bunch of util methods that are used by code generated for useBean,
getProperty and setProperty.
The __begin, __end stuff is there so that the JSP engine can
actually parse this file and inline them if people don't want
runtime dependencies on this class. However, I'm not sure if that
works so well right now. It got forgotten at some point. -akv
