服务器：resin-3.0.28 支持JSTL1.1

运行JSTL2.0时，会报如下异常，但页面可以显示：

com.caucho.jsp.JspLineParseException: jar:file:/D:/soft/resin-3.0.28/webapps/WEB-INF/lib/jstl-1.2.jar!/META-INF/c.tld:6: <taglib xmlns="http://java.sun.com/xml/ns/javaee"> is an unexpected top-level tag.

<jsp12:taglib xmlns:jsp12="http://java.sun.com/JSP/TagLibraryDescriptor">,
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"> or
<taglib xmlns=""> are expected.

Syntax: (<taglib> | (<taglib> | <jsp12:taglib>) | <jsp12:taglib> | <taglib>)

这是因为resin-3.0.28不支持JSTL2.0

这是因为页面引用的tld的uri写错了，造成读tld文件失败
