JSP accepting String[] as attribute to custom tag

JSP accepting String[] as attribute to custom tag

Hi viewers  In the below example I'm giving you the code samples that i have done for this task

Step 1: Create a dynamic web project in your eclipse
Step 2: create a package with any of your desired name  say    com.practice.customtags

Step 3: Create a java class with some name say SimpleTag.Java

 
package com.pratice.customtags;
import java.io.IOException;

import javax.servlet.jsp.JspWriter;
import javax.servlet.jsp.tagext.TagSupport;

public class SimpleTag extends TagSupport {
 private static final long serialVersionUID = 6997517813033042928L;
 private String[] input;
 
 public int doEndTag(){ 
  JspWriter out =pageContext.getOut();
    try {
     for(int i=0;i<input .length;i++){
          out.println(input[i]);
         }
  
 } catch (IOException e) {
  
  e.printStackTrace();
 }
    return EVAL_PAGE;
 }

 public String[] getInput() {
  return input;
 }

 public void setInput(String[] input) {
  this.input = input;
 }
  
}

Step 4: Create a new file with and save as custom.tld in your eclipse .save it under
               WebContent/WEB-INF/custom.tld

 
   1.0
  2.0
  Example TLD
  
    ObjectArray
    com.pratice.customtags.SimpleTag 
     
      input
      true
      java.lang.String[]
      true  
      false
    
   

Step 5: Create a jsp file index.jsp under WebContent folder of your dynamic web application

<%@ taglib prefix="My" uri="WEB-INF/custom.tld"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
   


<%String[] check={"naveen","rajesh","vivek"}; %>
   

Step: And Finally run the web application you will see the output as naveen
rajesh vivek Thanks and Regards Naveen
