JSP Learning Step 2nd-Tag use

Tag similar to an ASP. NET user control for dynamically displaying HTML

I first set up the tags directory in the project/webcontent/web-inf/to store the tag file

Create a new Message.tag file, as follows:

<%@ Tag Language="Java"pageencoding="UTF-8"%><%@ attribute Name="ID"type="java.lang.String"Required="true"Description="ID"%><%@ attribute Name="msg"type="java.lang.String"Required="true"Description="display text"%><%@ attribute Name="Description"type="java.lang.String"Required="false"Description="Tips" %><DivID= "${id}">message: ${msg}<BR/>Description:<span>${description}</span></Div>

To be used in the JSP interface, first introduce

<% @ taglib Prefix = " Tags " Tagdir = " /web-inf/tags " %>

Use:

<id= "msg"  msg= "RHYTHMK"  description= " My personal blog "></tags:message>

Attention:

The Tag property cannot be capitalized when it is defined, and the following error occurs when the ID is written as above:
