Thread: Scripting Variables

I am last year BSc(I.T) student.I have little bit knowledge of Java Programming Language.currently I am learning JSP(Java Server Pages). I want detail information about the Scripting Variables in JSP. If you are having any information about it, then please give me that, it will be helpful to me.Thanks in advanced.

if you declare variable from the JSP script then that variables are called as JSP scripting variable. So, the JSP tags Scripting variables are the variables are the page level variables declared by jsp tags. If you think about the variable below then you will come to know about the Jsp tag scripting variables:

Code:

<star:secondtag>
	<p align="center">Date value retrieved from JSP Tag : <%= time %></p>
</star:secondtag>

Following code which is given below is helpful for you to understand JSP tag variables.

Code:

package com.stardeveloper.tag.test;

import java.util.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;

public final class SecondTag implements Tag {

	private PageContext pc = null;

	
	public void setPageContext(PageContext p) {
		pc = p;
	}

	public void setParent(Tag t) {}

	public Tag getParent() { return null; }

	public int doStartTag() throws JspException {
		Calendar cal = Calendar.getInstance();
		pc.setAttribute("time", cal.getTime().toString());

		return EVAL_BODY_INCLUDE;
	}

	public int doEndTag() throws JspException {
		return EVAL_PAGE;
	}

	public void release() {
		pc = null;
	}
}
