gnujaxp.jar与struts2中的xwork核心包冲突

在做项目的时候，项目启动报了以下的错误

。。。。。。

 

从错误消息可以推断出原因无非两种：

1.项目中导入的jar包有问题，存在冲突。

2.项目中缺少jar包。

从实际情况出发，我觉得问题应该出在第一点。通过排除法，发现是gnujaxp.jar与struts2中的xwork核心包冲突，删除这个jar包就没有以上错误。

gnujaxp.jar是jfreechart中的jar包，jfree.org论坛里的说法：当使用JRE1.3.1并且要使用org.jfree.data.xml.*时才需要这个jar。

因此本次项目中不需要使用。删掉即可。而且，gnujaxp.jar与众多框架存在冲突，项目中不到迫不得已不应导入此包。
