以前写的代码没有问题，现在在新的机器上部署就报错：
2013-10-8 22:36:17 org.apache.catalina.core.StandardHostDeployer install
信息: Installing web application at context path /NetCTOSS_V3 from URL file:E:\Tomcat 5.0\webapps\NetCTOSS_V3
ERROR - Cannot load JDBC driver class 'oracle.jdbc.OracleDriver'
2013-10-8 22:36:28 org.apache.catalina.core.StandardContext start
严重: Error filterStart
2013-10-8 22:36:28 org.apache.catalina.core.StandardContext start
严重: Context startup failed due to previous errors
jar包也不缺啊。。tomcat下的servlet-api.jar也在。实在不知道什么原因了。求大家帮帮忙，不胜感激。我也在试探中。（看过有的资料说是eclipse的bug，搞不懂。自己感觉像spring配置文件的问题，还不敢确定，下面是配置文件内容）
