org.apache.catalina.connector.CoyoteAdapter服務嚴重：請求處理期間容器中發生異常或錯誤

Question

嘗試訪問應用程序時，我們在Tomcat中收到以下錯誤。 錯誤詳細信息如下。

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)

當用戶嘗試登錄Web應用程序時，會發生上述問題。 我們正在使用tomcat 6.0.18.0，並收到上述錯誤。

我也試圖通過eclipse運行它並得到以下錯誤

Answer 1

謝謝所有的問題都解決了。 上面的問題是因為由於屬性文件路徑中的空格字符而導致應用程序無法檢測到屬性文件，所以該應用程序無法連接到數據庫。 修復相同，問題得到解決。
