Hi Jeff!
Thanks for the fix. I found out the same solution in the meantime, but I'm
still struggling with another problem: I now added a tag file I created
myself and get weird errors from AntCompiler included in Jasper.
Here is my testdata:
index.jsp:
<%@ page language="java" contentType="text/html" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="tags" tagdir="/WEB-INF/tags" %>
<html>
<body>
<h2><c:out value="Hello"/> <tags:test testAttribute="World"/>!</h2>
</body>
</html>
WEB-INF/tags/test.tag:
<%@ attribute name="testAttribute" type="java.lang.String" required="true" %>
${testAttribute}
The Ant JspC task can create the sources and compile them without any
problems. When I use Maven, the following stacktrace is created:

The java file for the tag is created correctly, but it seems that it fails
compiling it.
