我想会是tomcat的缓存的问题。有时候 你需要进入tomcat吧之前部署的东西最好删了再重新部署

老大，你真狠啊这么多东西真够我们喝一壶的呵呵我感觉也是你的servlet配置出了问题,有一个映射找不到映射名称，至于hibernate 那些信息啊在程序加载的时候，tomcat都不会在开始的时候加载进容器里面，你忘了在web.xml里面有一个配置<startup>,我不是很明白你想知道什么呵呵先说到这里吧

[Quote=引用 11 楼 juanmiao 的回复:]

把doGET 呢
[/Quote]

首先我要谢谢你，
最后我想跟你说，你是自言自语还是混水摸鱼，大哥，我的代码是对的，如果你留意二楼和五楼的话，你就明白这个话题是不可能发生的，一个Servlet里有两个dopost（），首先编译就无法通过，那是我再粘贴复制时没改过来，请不要盯着这一个，因为这个不是关键，关键的是 tomcat启动信息，为什么启动信息。。。。。我已经明白了，9楼里我说了不想重复一遍，我想撞墙去，其实我重装后啥问题没有。。。。

你好好看看你这段代码对着吗
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

request.setCharacterEncoding("utf-8");
String name=request.getParameter("USERNAME");
String pwd=request.getParameter("USERPASSWORD");
if("aaa".equals(name)&&"111".equals(pwd)){
request.getRequestDispatcher("./success.jsp").forward(request, response);
}else{
request.getRequestDispatcher("./error.jsp").forward(request, response);
}


}

其实我也希望问题出在那，那样我就解脱了，问题就不是出在web.xml,后来我也写了一个struts对mysql里表做增删改查,结果报错信息一样,我卸掉myeclipse,tomcat,重新安装,结果可以了,

但是有新的问题出现:java.lang.NoClassDefFoundError: org/apache/commons/collections/CursorableLinkedList
最后我弄明白了,其实就是我的tomcat web/lib里少了一个jar,commons-collections-3.2.jar复制进去就可以了,至于前面为什么 就报出这么一大堆错,我也头大,晕了,因为一个简单的例子,能报出hibernate的错误,可见加载web里的工程相当丰富,问题虽然没有解决,我揣摩着应该是这样,我快服自己了!
没有人回帖就给你分吧

这种情况出现时,代表什么呢?
我可什么都没做,更不要说hibernate,我都没干事,hibernate的信息怎么都在发布里呢?
求解答,我明白,卸了tomcat,卸了myeclipse,重新装下,准行,问题是我明白拿出问题,求解答,只要回答的好,透彻我能懂,我可以加分.

servlet里

Java code

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
}……
[/Quote]

我发错了，我写的是doGet,xml没有问题，你看tomcat信息就会发现，找到xml并加载了
后面还有一点东西

public void doGet(HttpServletRequest request, HttpServletResponse response)

doPost(request,response);
}

另外，web.xml要进行配置

<servlet>
<servlet-name>xxxx</servlet-name>
<servlet-class>包名字.Servlet类名</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>xxxx</servlet-name>
<url-pattern>/addUserServlet</url-pattern>
</servlet-mapping>
