我是靠谱客的博主疯狂酒窝，最近开发中收集的这篇文章主要介绍gnujaxp.jar与axis冲突问题，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

一个Web应用程序，在WTP里无法完成web services向导，手工配置axis后访问http://localhost:8080/myapp/servlet/AxisServlet时提示如下错误：

org.apache.axis.InternalException: org.apache.axis.ConfigurationException: org.apache.axis.deployment.wsdd.WSDDException: Must include type attribute for Handler deployment!

经排除法发现只要删除WEB-INF/lib下的gnujaxp.jar即恢复正常。这个jar文件是因为应用程序使用到jfreechart带来的，按照jfree.org论坛里的说法，只有使用jre1.3.1版本jfreechart才真正需要此文件，所以删掉它问题解决，WTP里web services向导恢复正常。

BTW, 除了axis，这个gnujaxp.jar好像还和spring、ibatis等环境有冲突，见这个google查询结果。
