Hi, I am trying to run a custom tag in JRUN.
I placed my
jsp and dlt file in:
JRun\servers\default\default-app\
and I placed my class file in:
JRun\servers\default\default-app\WEB-INF\classes
my dlt file looks like this:
<?xml version = "1.0" encoding = "ISO-8859-1" ?>
<!DOCTYPE taglib PUBLIC
"-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
<taglib>
<tlibversion>1.0</tlibversion>
<jspversion>1.0</jspversion>
<shortname>advjhtp1</shortname>
<info>
A simple tag library for the examples
</info>
<tag>
<name>welcome</name>
<tagclass>
WelcomeTagHandler
</tagclass>
<bodycontent>empty</bodycontent>
<info>
Inserts content welcoming user to tag libraries
</info>
</tag>
</taglib>
my
java file looks like this:
import java.io.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class WelcomeTagHandler extends TagSupport{
//method called to begin tag processing
public int doStartTag() throws JspException{
//attempt tag processing
try{
//obtain jspWriter to output content
JspWriter out = pageContext.getOut();
//output content
out.print("Welcome to JSP Tag Libraries");
}
catch(IOException e){
throw new JspException(e.getMessage());
}
return SKIP_BODY;
}
}
and my jsp file looks like this:
<?xml version = "1.0"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml-strict.dtd">
<%-- taglib directive --%>
<%@ taglib uri = "advjhtp1-taglib.tld" prefix = "advjhtp1" %>
<html xmlns = "http://www.w3.org/1999/xhtml">
<head>
<title>Simple Custom Tag Example</title>
</head>
<body>
<p>The following text demonstrates a custom tag:</p>
<h1>
<advjhtp1:welcome />
</h1>
</body>
</html>
I get the following error when trying to run the jsp:
/customTagWelcome.jsp:
javax.servlet.ServletException: Parse Error in JSP page: The tag handler class '
WelcomeTagHandler
' for custom tag 'welcome' on line '16' could not be found.
I tried everything. i tried using a package, i tried placing the class file in every possible directory. but it just can't seem to find the class file for some reason.
does anyone know where exactly all the necessary files need to be in order to run properly?
Thank you
