Hello again!
I've another question regarding th JspC plugin: I build a very simple web
app based on the webapp archetype and want to precompile the JSPs with the
plugin. I want to use tag libraries like JSTL. I tried to compile a sample
JSP with the following content:
<%@ page language="java" contentType="text/html" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<body>
<h2>Hello World!</h2>
</body>
</html>
When I call the JspC plugin, the following error occurs:
[INFO] [jspc:compile {execution: jspc}]
[INFO] jspc args: [-uriroot, V:\Development\testWebapp/src/main/webapp,
-d, V:\Development\testWebapp/target/jsp-source, -s, -l, -webinc,
V:\Development\testWebapp/target/web-fragment.xml, -p, jsp]

<!-- [INSERT FRAGMENT HERE] -->
<display-name>Archetype Created Web Application</display-name>
</web-app>
As standard.jar contains the file c.tld in the META-INF directory with the
tag library definition for the specified URI, the library should be
present in the classpath
Thanks,
