我从服务器复制了一个应用程序，然后部署到Tomcat6(与服务器相同)，但我总是得到错误!尝试重装Tomcat，还是报错。

错误 1:

   desc:there are  the classes that could not found by tomcat still in the path /web_inf/lib

问题1:它有什么问题？

问题2:error1和error2有关系吗？

好的，这是竞争堆栈跟踪

最佳答案

Question1: What's wrong with it?

第一个错误看起来像是 webapp 或其配置中的错误。 Tomcat 报告当 web 应用程序关闭时某些东西(例如其中一个 servlet)没有正确整理。如果不解决这个问题，您的网络服务器可能会在几次 webapp 重新启动后耗尽内存。

第二个错误是提示找不到某些类。这可能是某种网络服务器或网络应用配置错误。

在这两种情况下，如果您向我们展示完整的堆栈跟踪，将会有所帮助。

Question2: Is there any relation between the error1 and error2?

可能不会。

一点点挖掘告诉我，您可能会在名为 axis-x.y.jar 的 JAR 文件中找到 org.apache.axis.transport.http.AdminServlet或类似的东西(完整列表请参见 http://findjar.com/class/org/apache/axis/transport/http/AdminServlet.html)

对于 org.jdom.input.SAXBuilder 寻找像 jdom-x.y.jar 这样的文件(完整列表参见 http://findjar.com/class/org/jdom/input/SAXBuilder.html)

第二个错误与您最初报告的错误不同，但它仍然是 webapp 中的错误。这可能是您第一个错误的结果；即假设 servlet 正常启动。

您需要查看安装在 Tomcat 上的 Web 应用程序，并查看 Axis 和 JDOM JAR 是否位于 WEB-INF/lib 中。如果没有，请返回到您从中复制 webapp 的服务器，然后查看那里的 webapp ...以及服务器的公共(public)图书馆区域。 (你不说你从什么样的服务器复制...)

关于java - 找不到 Tomcat 类 & 路径 WEB-INF\lib 中有该类，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5633239/
