jpa 连SQL2000数据库报错

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'RecordDAO': Injection of persistence dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/spring.xml]: Invocation of init method failed; nested exception is java.lang.AbstractMethodError: com.microsoft.jdbc.base.BaseDatabaseMetaData.supportsGetGeneratedKeys()Z

得知是microsoft提供的数据库驱动存在bug。需要换一种驱动连接，使用jtds（下载地址：http://sourceforge.net/projects/jtds/files/）下载jtds1.2版，解压得到jtds-1.2.jar，引用到eclipse中项目目录下（去除原驱动引用），更改hibernate配置文件：

原驱动连接配置：

 <property name="connection.driver_class">com.microsoft.jdbc.sqlserver.SQLServerDriver</property>
  <property name="connection.url">jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=portal</property>
更改jtds连接：   
  <property name="connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
  <property name="connection.url">jdbc:jtds:sqlserver://127.0.0.1:1433;DatabaseName=portal</property>

问题得到解决。补充：java代码调原驱动连接数据库是没有问题的，搭配hibernate会有此问题。
