警告: Unhandled Exception thrown: class java.lang.NullPointerException

信息: java.lang.NullPointerException
這個錯誤有可能是因為由于長時間沒有用頁面,導致頁面Session失效,從session里面取出數據的時候導致的錯誤!
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Invalid column name: XXXXX
at com.microsoft.jdbc.base.BaseExceptions.createException(Unknown Source)
at com.microsoft.jdbc.base.BaseExceptions.getException(Unknown Source)
at com.microsoft.jdbc.base.BaseResultSet.getColumnOrdinal(Unknown Source)
at com.microsoft.jdbc.base.BaseResultSet.getInt(Unknown Source)
這個錯誤是因為在sql語句里面沒有寫某些字段，但是在下面對取出結果操作時，經行了其他字段的讀取
HTTP Status 500 - No input attribute for mapping path /operatorSelectCarowner
type Status report
message No input attribute for mapping path /operatorSelectCarowner
description The server encountered an internal error (No input attribute for mapping path /operatorSelectCarowner) that prevented it from fulfilling this request.
是因為你在action里面配置的時候配置上了attribute和name屬性,但是沒有寫input屬性,在運行validate方法的時候,要檢測input屬性的!
