The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Trouble with simple custom tag

Asked by andrew200 in Java Programming Language, Java Standard Tag Library (JSTL) & Server Tags, Extensible HTML (XHTML)

Tags: tag, load, handler

I am trying to run a sample custom tag java application. I get this error:

org.apache.jasper.JasperException: /index.jsp(23,4) Unable to load tag handler class "java.TestTagClass" for tag "tt:TestTag"

I have double and triple checked all of the paths and directory structure but the error remains the same.

Here is what I have:

The directory structure starts with the root at: c:\Java Projects\WebStuff\WebApplication3

I think these are the important files:

build\web\index.jsp
build\web\WEB-INF\classes\java\TagTest.class
build\web\WEB-INF\lib\jstl.jar
build\web\WEB-INF\lib\standard.jar
build\web\WEB-INF\tlds\TLDTest.tld
build\web\WEB-INF\web.xml

here are some code snippets:

index.jsp:

<%@ taglib uri="TheTag" prefix="tt"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>JSP Page</h1>

<tt:TestTag/>

</body>
</html>

</taglib>
</web-app>

<taglib version="2.0" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-jsptaglibrary_2_0.xsd">

<uri>/WEB-INF/tlds/TDLTest</uri>
<tag>
<name>TestTag</name>
<tagclass>java.TestTagClass</tagclass>
</tag>
</taglib>

_______________________________________________

I suspect that for some reason the java.TestTagClass in not being found because I can change the <tagclass> value to anything and I get the same error.

I really want to get this thing to work so I can move on-- your help is appreciated!

Thanks
