1.
Create a handler file
like : myTag.java
package mypac;
import java.io.IOException;
import javax.servlet.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
// writer: @author ashy
public class myTag extends BodyTagSupport {
/** Creates a
new instance of myTag */
public myTag() {
}
String color;
public void
setColor(String color)
{
this.color=color;
}
public int
doStartTag()throws JspException
{ try
{
JspWriter
jw=pageContext.getOut();
jw.println("<table bgcolor='"+color+"'");
jw.println("><tr><td>");
}
catch(Exception
e)
{ }
return EVAL_BODY_INCLUDE;
}
public int
doEndTag()
{
try{
JspWriter jw=pageContext.getOut();
jw.println("</td><tr/></table>");
}
catch(Exception e)
{ }
return
EVAL_PAGE;
}
}
2. Create a tag handler
under tlds folder under WEB-INF folder like:bodyTagLib.tld
Code:
<?xml version="1.0"
encoding="UTF-8"?>
<taglib version="2.0"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
web-jsptaglibrary_2_0.xsd">
<tlib-version>1.0</tlib-version>
<short-name>bodytaglib</short-name>
<uri>/WEB-INF/tlds/bodyTagLib</uri>
<tag>
<name>ashwani</name>
<tag-class>mypac.myTag</tag-class>
<body-content>jsp</body-content>
<attribute>
<name>color</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
</tag>
</taglib>
3. Final step is to
implement this tag like:
Code:
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib uri="/WEB-INF/tlds/bodyTagLib.tld"
prefix="m"%>
<html>
<head>
<meta
http-equiv="Content-Type" content="text/html;
charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>JSP
Page</h1>
<m:ashwani
color="red">
ashwani
</m:ashwani>
</body>
</html>
