java tomcat 6崩溃新webapp

Question

我被要求接管一个Java webapp的主机，我以前从未使用过Java，我被告知Tomcat是我的选择，所以我有一个开启了Tomcat 6的windows服务器，我上传了该网站并创建了虚拟主机，该网站似乎对我来说运行良好，然后我接到一个电话，editlead上的语言验证出现了问题。jsp并在tomcat的引导中添加-xverify:none`解决了这个问题

今天服务器崩溃了，我无法重新启动服务，我不得不重新启动旧的服务，在这两次发生后，服务器停止崩溃，甚至试图复制他们在办公室可能做的事情，看看我是否能导致它崩溃，但没有

我试着阅读日志，但它让我感到困惑，所以如果有人能帮忙，我就把它们贴在下面

如果不了解LeadHandlerServlet中的情况，就很难判断这里发生了什么。我猜在第338行的doPost（）中有类似的内容：

RequestDispatcher appDispatcher=getServletContext（）。getRequestDispatcher（someURL）； appDispatcher。转发（请求、响应）

我看不到密码。但这可能是对forward（）的第二次调用。如果是的话，它会吹坏垫圈。一般来说，你需要在呼叫forward（）后，让你肮脏的小手远离回应。通常，人们在调用return语句后立即粘贴它，并让后续的传入线程处理下面可能存在的任何逻辑
