Simple JSP - Attribute invalid for tag according to TLD

My project in eclipse -

enter image description here

I get the error below when I run MyTagUser.jsp - HTTP Status 500 - /jsp/MyTagUser.jsp(14,0) Attribute subTitle invalid for tag Header according to TLD 

org.apache.jasper.JasperException: /jsp/MyTagUser.jsp(14,0) Attribute subTitle 
invalid for tag Header according to TLD

org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40)
 org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:407)...etc.

Snippet from Header.jsp - 

<body>
<img src="../images/java_logo.gif"><br>
<em><strong> ${subTitle} </strong></em> <br>
</body>

Snippet from MyTagUser.jsp - 

<%@ taglib prefix="myTags" tagdir="/WEB-INF/tags"%>
<html>
<head>
</head>
<body>
<myTags:Header  subTitle="Java is the best !!!" />
JSP and Servlets.
</body>
</html>
Solution

  • You must use the attribute directive in your Header.tag file as show below - 

    <body>
<%@ attribute name="subTitle" required="true" rtexprvalue="true" %>
<img src="../images/java_logo.gif"><br>
<em><strong> ${subTitle} </strong></em> <br>
</body>
