NO.14 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
a message using the java.text.MessageFormat class. The tag will take the resourceKey attribute and a
variable number of argument attributes with the format, arg<N>. Here is an example use of this tag and its
output:
<t:message resourceKey='diskFileMsg' arg0='MyDisk' arg1='1247' />
generates:
The disk "MyDisk" contains 1247 file(s).
Which Simple tag class definition accomplishes this goal of handling a variable number of tag attributes?
A. public class MessageTag extends SimpleTagSupport

NO.17 You are creating a JSP page to display a collection of data. This data can be displayed in several
different ways so the architect on your project decided to create a generic servlet that generates a
comma-delimited string so that various pages can render the data in different ways. This servlet takes on
request parameter: objectID. Assume that this servlet is mapped to the URL pattern: /WEB-INF/data.
In the JSP you are creating, you need to split this string into its elements separated by commas and
generate an HTML <ul> list from the data.
Which JSTL code snippet will accomplish this goal?
