Web services Liferay Prolet Web服务错误

我的liferay portlet有问题

我很好地部署了portlet，并在站点中使用它

我的portlet中有一个API/Web服务。几天前它还可以正常工作，但现在我遇到了一个ClassCastException

有什么问题吗

以下是stacktrace：

提前感谢

看起来portlet和服务器库中有重复的axis JAR。先检查一下

liferay-portal-6.1.10-ee-ga1\tomcat-7.0.25\webapps\ROOT\WEB-INF\lib

---

vs您的portlet libs。

我没有检查它，但是从我的portlet中删除了所有jar文件，并且它工作了，因此您所说的可能与问题有关。谢谢
