Use JSP Tag with content body

March 17th, 2010

1.First add this to web.xml:

1
2
3
4

    <taglib>
      <taglib-uri>http://longshine.com/cufj</taglib-uri>
      <taglib-location>/WEB-INF/tlds/cufjTag.tld</taglib-location>
    </taglib>

2.Put the tld file into folder: /WEB-INF/tlds/. And the tld file is like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE taglib
  PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
  "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
    <tlib-version>1.0</tlib-version>
    <jsp-version>1.2</jsp-version>
    <short-name>cufjTag</short-name>
    <uri>http://longshine.com/cufj</uri>
 
    <tag>
      <name>role</name>
      <tag-class>longshine.telecom.mob.tag.RoleTag</tag-class>
      <body-content>JSP</body-content>
      <attribute>
      	<name>roleIds</name>
      	<required>true</required>
      </attribute>
    </tag>   
</taglib>

3.Now is the java class:

1

13

package longshine.telecom.mob.tag;
 
import java.io.IOException;
 
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.BodyContent;
import javax.servlet.jsp.tagext.BodyTagSupport;
 
import longshine.telecom.mob.common.SessionUserObject;
import longshine.telecom.mob.service.BaseService;
 
public class RoleTag extends BodyTagSupport {
 
	private static final long serialVersionUID = 1L;
	private String roleIds;
 
	public int doEndTag() throws JspException {
		BodyContent bc = getBodyContent();
		if (roleIds != null) {
			SessionUserObject sessionUserObject = (SessionUserObject) pageContext.getSession()
				.getAttribute(BaseService.SESSION_USER_OBJECT);
			if (sessionUserObject == null || sessionUserObject.getPermissions() == null) {
				return SKIP_BODY;
			}
			String[] roles = roleIds.split(",");
			for (int i = 0; i < roles.length; i++) {
				if (sessionUserObject.getPermissions().contains(roles[i])) {
					try {
						pageContext.getOut().print(bc.getString());
						return SKIP_BODY;
					} catch (IOException e) {
						e.printStackTrace();
					}
				}
			}
		}
		return SKIP_BODY;
	}
 
	public String getRoleIds() {
		return roleIds;
	}
 
	public void setRoleIds(String roleIds) {
		this.roleIds = roleIds;
	}
}

5.At last, you can write JSP with this tag, remember to declare this tag in the JSP head:
<%@taglib uri="http://longshine.com/cufj" prefix="c" %>

1

5
6

14
15

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@taglib uri="http://longshine.com/cufj" prefix="c" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP TAG</title>
</head>
<body>
 
<c:role roleIds="002">
	<input type="text" name="n"></input>
</c:role>
 
</body>
</html>

Enjoy it!
