JspRuntimeContext.java
jasper2/src/share/org/apache/jasper/servlet JspServlet.java

Added JSP monitoring facility.
Initially, the number of JSPs that have been loaded into a webapp is exposed
as a monitorable attribute. Additional attributes (e.g., number of JSPs whose
compilation failed, etc.) may follow.
