Why Can't..?

package com.example.web;
 
import javax.servlet.jsp.tagext.*;
import javax.servlet.jsp.*;
import java.io.*;
 
public class SampleTagHandler extends BodyTagSupport{
 
public int doStartTag() throws JspException{
try{
pageContext.getOut().println("I am John -- IN doStartTag()");
}catch(Exception e){
e.printStackTrace();
}
return EVAL_BODY_INCLUDE;
}
 
public int doAfterBody() throws JspException{
try{
pageContext.getOut().println("How r u? -- IN doAfterBody()");
}catch(Exception e){
e.printStackTrace();
}
return SKIP_BODY;
}
 
public int doEndTag() throws JspException{
try{
pageContext.getOut().println("I am leaving -- IN doEndTag()");
}catch(Exception e){
e.printStackTrace();
}
return EVAL_PAGE;
//return SKIP_PAGE;
}
 
}

hello john,,

what will be the output for the above program you have given?
I read somewhere that if we want to print from a doAfterBody() we have to used previousOut implicit variable!!!


please give me a explanation about this...
