Environment Running under:
JBoss Version : 4.0.2
| JDK Version : 1.4.2
|
| I am using the Custom Tag Lib to iterate over the data. I am having a
problem with the output of the jsp while using the custom tag lib.
|
| The output from Jsp Page when accessed first time is :
|
| anonymous wrote : Hello
| | Hello Again
| | Hello Again
| | Hello Again
|
| When I try to re-visit the page or refresh the page again then the output
from the Jsp Page is :
|
| anonymous wrote : Hello
| | Hello Again
|
| The source code:
|
| RepeatHelloTag.java:
|
|
|
| | package com.masslight.tagExampleClasses;
| |
| | import javax.servlet.jsp.*;
| | import javax.servlet.jsp.tagext.*;
| | import java.io.*;
| |
| | public class RepeatHelloTag extends
javax.servlet.jsp.tagext.BodyTagSupport {
| | int count = 1;
| | int numberOfIterations = 3;
| | String greeting = new String("Hello <BR>");
| | public int doStartTag() throws JspTagException {
| | try {
| | pageContext.getOut().print(greeting);
| | } catch (Exception ex) {
| | throw new JspTagException("IO problems");
| | }
| | return EVAL_BODY_BUFFERED;
| | }
| | public int doAfterBody() throws JspTagException {
| | try {
| | if (count < numberOfIterations) {
| | count++;
| | return EVAL_BODY_BUFFERED;
| | }
| | else {
| | BodyContent bodyContent = getBodyContent();
| | bodyContent.writeOut(getPreviousOut());
| | return SKIP_BODY;
| | }
| | }
| | catch (Exception e) {
| | throw (new JspTagException("error"));
| | }
| | }
| | }
| |
|
| The Jsp File :
|
|
| tagExample.jsp
|
| <%@ page language="java" %>
| | <%@ taglib uri="WEB-INF/tagExampleLib.tld" prefix="greeter" %>
| | <html>
