class "org.apache.commons.collections.CursorableLinkedList"'s signer information does not match signer information of other classes in the same package
在做Struts + Hibernate 的项目时遇到了这个问题,纠缠了几天,在网上找了几篇,才大概找到了问题原因,是包冲突。但没有一个比较完整的描述。我的理解就是下面这些:
异常是说org.apache.commons.collections的数字签名和其他类的不匹配。
在Struts 1.2 的核心包里有一个commons-beanutils.jar 这个的版本是1.7.0,里面有commons.collections。(你可以打开这个jar看看,里面确实有这个东西)而在Hibernate 3.0 的核心包也有一个commons-collections.jar。这就造成了冲突。
解决方法:将Struts 1.2 的核心包里有一个commons-beanutils-1.7.0.jar 换成commons-beanutils-1.6.1版本的包。这样就不会再出这个异常了。呵呵。
