You are writing a JSP that includes scriptlet code to declare a List variable and initializes that variable to anArrayList object.

Assume the custom tag my：errorProne always throws a java.lang.RuntimeException with the message "Filenot found." An error page has been configured for this JSP page.
Which option prevents the exceptionthrown by my：errorProne from invoking the error page mechanism， and outputs the message "File notfound" in the response？（）

You are building a web application that will be used throughout the European Union； therefore， it has significant internationalization requirements. You have been tasked to create a custom tag that generates amessage using the java.text.MessageFormat class. The tag will take the resourceKey attribute and a variable number of argument attributes with the format， arg. Here is an example use of this tag and itsoutput：  generates： The disk "MyDisk"contains 1247 file（s）.
Which Simple tag class definition accomplishes this goal of handling a variable number of tag attributes？（）
