紧急求救：Servlet /mp threw load() exception

[ustbjack]

项目mp布置到tomcat后，启动出错：

很有可能是classpATHpath问题，我说的是项目的classPath 。包的那个。 或者少包。

[ustbjack]

能说的具体些吗？项目中引入了Hibernate3.2和structs1.2。是不是包有冲突呢？

[wenjjing2lianee]

给LZ一个差不多的贴,应该有帮助:

[wenjjing2lianee]

可能情况很多:
用resin3.*以上版本跑struts1.2的程序时，启动会出现javax.servlet.UnavailableException at org.apache.struts.action.ActionServlet.init(ActionServlet.java:368)异常
问题出在struts1.2中的commons-digester.jar包，将struts1.1中的commons-digester.jar包替换struts1.2中的包就可以解决这问题了。

[ustbjack]

在Myeclipse下同样的另外的项目没有问题[Quote=引用 3 楼 wenjjing2lianee 的回复:]

你的struts和web配置文件正确么？ActionServlet设置为load-on-startup了么？

[ustbjack]

不是跟引入Hibernate和structs的顺序有关吧？
