Question

我们在JBOSS 4.0.2中的jsp中使用JSTL。在使用标记库时，我们得到以下异常。当在tomcat 7上本地部署但在服务器jboss上部署时，不会发生错误

javax.servlet.ServletException: javax.servlet.jsp.tagext.TagAttributeInfo.<init>(Ljava/lang/String;ZLjava/lang/String;ZZ)V
    org.apache.jasper.servlet.JspServlet.service(JspServlet.java:272)

这是JSP代码：

    pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>

                <tr>

                                   </tr>

                </c:forEach>

</div>

据我所知，JBoss 4.0.2没有嵌入JSTL库。将jstl.jar和standard.jar添加到应用程序的lib文件夹中。下载，取决于您要使用的JSTL版本：

http://repo2.maven.org/maven2/javax/servlet/jstl/（JSTL 1.1）和
http://repo2.maven.org/maven2/taglibs/standard/

JSTL标记在jboss 4.0.2中抛出错误
