java - org.apache.catalina.connector.CoyoteAdapter 服务严重 : An exception or error occurred in the container during the request processing

Question

尝试访问应用程序时，我们在 Tomcat 中遇到以下错误。错误详情如下。

org.apache.catalina.connector.CoyoteAdapter service
SEVERE: An exception or error occurred in the container during the request processing java.lang.NullPointerException
    at com.ify.sabs.limi.app.servlets.LoginValidate.doPost(LoginValidate.java:77)
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:637)
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
    at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290)
    at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)

当用户尝试登录到 web 应用程序时，会发生上述问题。我们正在使用 tomcat 6.0.18.0 并收到上述错误。

我也尝试通过 eclipse 运行它并得到以下错误

感谢所有问题都已解决。上述问题是因为应用程序无法连接到数据库，因为属性文件路径中的空格字符导致应用程序无法检测到属性文件。修复了同样的问题，问题得到了解决。
