Class Compiler

java.lang.Object

  +--org.apache.jasper.compiler.Compiler

Direct Known Subclasses:

CommandLineCompiler, JspCompiler

public class Compiler

extends java.lang.Object

If you want to customize JSP compilation aspects, this class is something you should take a look at. Hope is that people can just extend Compiler and override things like isOutDated() but inherit things like compile(). This might change.
