雪地跪求各位大神帮忙看一下！
1. 原来的项目是在javaSE1.4下编译，部署在tomcat5中，现在把原项目拷贝的javaSE1.7下编译，部署在tomcat7中。
2. 在struts1.3.8中自定义的标签的标签不能被解析到，标签定义如下：
<?xml version=”1.0″ encoding=”UTF-8″ ?>
<taglib 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 http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd”
version=”2.0″>
<description>itcast babasport permission taglib</description>
<display-name>permission taglib</display-name>
<tlib-version>1.0</tlib-version>
<short-name>itcast</short-name>
<uri>http://www.itcast.cn/babasport</uri>
<tag>
<description>权限校验标签，有权限就显示标签体的内容，否则不显示</description>
<name>permission</name>
<tag-class>cn.itcast.web.taglib.PermissionTag</tag-class>
<body-content>JSP</body-content>
<attribute>
<description></description>
<name>module</name>
<required>true</required>
<rtexprvalue>false</rtexprvalue>
</attribute>
<attribute>
<description></description>
<name>privilege</name>
<required>true</required>
<rtexprvalue>false</rtexprvalue>
</attribute>
</tag>
</taglib>
3. 运行结果如下所示：
