SpringSide 3.0.3不能通过

SpringSide 3.0.3 Stable版，导入后
启动Tomcat就一直报错:
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'http'.
在官方网站上看了，说是少jar包，可是我不知道少了什么jar包

看一下，spring-security-core-*.*.*.jar、spring-security-acl-*.*.*.jar、spring-security-taglibs-*.*.*.jar，Spring Security的包。

在的XSD配置文件中缺少 http的定义，而在配置文件中你使用了的标签。
