'How JSP Container finds which class file is oldest and newest [Struts2]?
I have been learning JSP for a while now and I was curious in knowing how JSP files are converted into HTML. While learning about that process, I came into this concept that JSP files are generated to Java Servlet files and they are compiled into Servlet Class files. These class files are stored in JSP Container and when the corresponding JSP file is requested, the corresponding servlet class file is executed. My question is how JSP Container knows if the JSP file had changed from the old compiled one and in which manner it compares both the files?
