The JSP File

• First, write the tag handler class and the .tld file.  Then, you can hack away at the jsp.
• Before you use the tag, you must use the taglib directive.  There are two acceptable forms.
• <%@ taglib uri="mytaglib.tld" prefix="mytags" %>
• This points directly to the .tld file.  It is the quickest, but least flexible.
• <%@ taglib uri="/mytags" prefix="mytags" %>
• This will look in the web.xml deployment file first.  This XML file has a <taglib> tag with two subtags, <taglib-uri> and <taglib-location> that define where the .tld file is located.  That makes it easy to change locations without changing the source code if you need to.
• You use the prefix, followed by a colon and the tag name, to access the tag throughout your jsp.  Just make sure to put the taglib directive first!
• For example, if the previous tld were saved in the root directory and named named mytaglib.tld, and we wanted to access the foo tag, we would use this syntax:

<%@ taglib uri="mytaglib.tld" prefix="mytags" %>
<mytags:foo att1="98.5" att2="92.3" att3="107.7">
