The type org.apache.axis2.description.DescriptionConstants cannot be resolved.

[Icandoeverything]

Eclipse3.5中导入一个能正常运行的工程时，出现The type javax.servlet.ServletException cannot be resolved.错误，按照提示修改了编译路径，导入了javax.servlet.*包以后，却又出现The type org.apache.axis2.description.DescriptionConstants cannot be resolved.的错误，不知何故？请教高手，如何解决？Google了一下，只有四个搜索结果，没有什么参考价值。烦请各位大侠帮小弟一把？
