关于displayTag的问题
这两天在看displayTag标签。很想试试，不过我找到了1.2的jar包。不知道怎么用。在网上找了很多资源就是没有怎么配的。我的工程的Lib中的jar包如下：
antlr.jar
commons-beanutils.jar
commons-digester.jar
commons-fileupload.jar
commons-lang.zip
commons-logging.jar
commons-validator.jar
displaytag-1.2.jar
jakarta-oro.jar
standard.zip
struts.jar
这本来是一个测试struts1.2的小工程
在jsp页面上
<%@taglib uri ="http://displaytag. prefix="display" %>
现在报的异常：
