部署项目战时出现Tomcat错误

我在我的服务器CentOS上的tomcat6中部署文件战时出现问题。部署项目战时出现Tomcat错误

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)

这是一个错误时启动Tomcat开始部署

</beans>

请帮我大家，谢谢... :)

它似乎有一些错误您的查询。。！准备好的声明本身就表明了这一点。你的查询是否在你的数据库上执行？

根据您的堆栈跟踪，您看起来像在您的egovframework.com.sym.sym.bak.service.BackupScheduler类的init（）方法中有NullPointerException。

正如马修所说，您的堆栈跟踪显示backupScheduler bean的初始化运行到空指针。

从看你的.xml文件的backupScheduler bean包含一个名为“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，但我没有看到被宣布在此.xml文件的任何地方这个bean。这个bean是在其他地方声明的吗？

大家好，我已经部署在其他服务器上的这个项目，它工作。但在上面的服务器上它不起作用。关于 egovBackupResultIdGnrService，我已经在其他文件中声明了xml准备好了。我认为从JVM问题的根源。我不确定。你有什么主意吗？ – sonida 2012-01-09 01:27:54
