部署項目戰時出現Tomcat錯誤

我在我的服務器CentOS上的tomcat6中部署文件戰時出現問題。部署項目戰時出現Tomcat錯誤

我用

的CentOS 5.x的
的Tomcat版本6
Java版本（我用javasun）

java version "1.6.0_30" 
Java(TM) SE Runtime Environment (build 1.6.0_30-b12) 
Java HotSpot(TM) Client VM (build 20.5-b03, mixed mode, sharing)

這是一個錯誤時啓動Tomcat開始部署

這裏是文件上下文調度符號均三bak.xml

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

     <property name="idgenService" ref="egovBackupResultIdGnrService"/> 
    </bean> 


</beans>

請幫我大家，謝謝... :)

它似乎有一些錯誤您的查詢。。！準備好的聲明本身就表明了這一點。你的查詢是否在你的數據庫上執行？

根據您的堆棧跟蹤，您看起來像在您的egovframework.com.sym.sym.bak.service.BackupScheduler類的init（）方法中有NullPointerException。

正如馬修所說，您的堆棧跟蹤顯示backupScheduler bean的初始化運行到空指針。

從看你的.xml文件的backupScheduler bean包含一個名爲「egovBackupResultIdGnrService」

<bean id="backupScheduler" class="egovframework.com.sym.sym.bak.service.BackupScheduler" 
    init-method="init" destroy-method="destroy"> 
    <property name="egovBackupOpertService" ref="egovBackupOpertService"/> 

    <-- THIS BEAN RIGHT HERE --> 
    <property name="idgenService" ref="egovBackupResultIdGnrService"/> 
</bean>

bean的引用，但我沒有看到被宣佈在此.xml文件的任何地方這個bean。這個bean是在其他地方聲明的嗎？

大家好，我已經部署在其他服務器上的這個項目，它工作。但在上面的服務器上它不起作用。關於 egovBackupResultIdGnrService，我已經在其他文件中聲明瞭xml準備好了。我認爲從JVM問題的根源。我不確定。你有什麼主意嗎？ – sonida 2012-01-09 01:27:54
