Struts1.2+hibernate2+spring2.5+displaytag1.11配置出错！求救！！

[b]最近在做一个java web项目的时候想用displaytag进行分页，在网上搜了好多资料后自己尝试配置，可是配置后项目无法启动！如果去掉dispalytag相关内容则可以正常运行！[/b]

我的服务器时tomcat6.0的，IDE开发环境是MyEclipse Blue 7.0M2。具体配置过程如下（Struts Spring Hibernate配置没有问题，配置过程不叙述）：
1、将displaytag的相关jar包拷贝到项目的/web-inf/lib目录下。
2、将displaytag中的css、img、images卡被到项目的webroot目录下。
3、在jsp页面中添加<%@ taglib uri="http://displaytag.sf.net" prefix="display"%>。

重新部署项目、发布包以下错误，（急切寻求好心人帮忙！）：
