堆栈跟踪中的这一行看起来最有趣：

103625 [main] ERROR org.hibernate.util.JDBCExceptionReporter:78  
    - ERROR: column this_.id does not exist

我的猜测是，您的hibernate

@Entity

类声明了一个名为

id

的列，但不存在这样的列（可能该列实际上名为

table\u id

等）。

从您的日志中，不清楚您是否在

com.mycom.Myapp.manager.SystemServlet.contextInitialized（）中抛出异常

或者您只需记录一个异常即可查看发生了什么。如果您在那里抛出错误（即Tomcat可以看到的错误），启动将失败。只需注释掉异常，看看是否导致您的问题。

请提供您在webapp中尝试执行的操作，以及一些导致问题的代码片段。仅仅提供跟踪是没有帮助的！感谢您的快速响应，是的，它被故意忽略了，剩下的问题怎么解决呢？当您说“故意忽略”时，这是指您想忽略异常，还是您编写了一些代码以确保Tomcat看不到它？@venkat2010:Hibernate错误是web应用程序无法启动的原因。这是不容忽视的。
