Creating Your Own Custom JSP Tags

This free, multimedia tutorial shows you how to use IBM's Rational Application Developer (IRAD) 6.0 to create a custom tag library (well, one custom tag, so it is a pretty impoverished library), and the corresponding Java code and tld file to make a custom tag work on a JSP page.

import java.io.IOException;

import javax.servlet.ServletContext;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpSession;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.JspWriter;
import javax.servlet.jsp.tagext.TagSupport;

import com.examscam.common.Timer;


public class TimerTag extends TagSupport {


public int doStartTag() throws JspException {
JspWriter out = pageContext.getOut();
ServletRequest request = pageContext.getRequest();
ServletResponse response = pageContext.getResponse();
ServletContext application = pageContext.getServletContext();
HttpSession session = pageContext.getSession();

Timer t = (Timer)session.getAttribute("timer");
if (t==null){
t = new Timer();
session.setAttribute("timer", t);
}
try {
out.print("Elapsed Time: " + t.getElapsedTime());
out.print("Start Time: " + t.getStartTime());
} catch (IOException e) { e.printStackTrace();
} return SKIP_BODY;
}
}
