錯誤，而堅持記錄

Question

我想在遠程數據庫中堅持一條記錄。不過，我收到以下錯誤：

Exception [EclipseLink-4003] (Eclipse Persistence Services - 2.1.3.v20110304-r9073): org.eclipse.persistence.exceptions.DatabaseException

這裏是我的的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="1.0" 
    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> 
    <persistence-unit name="prjEjbProj" transaction-type="RESOURCE_LOCAL"> 
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> 
<!--  <jta-data-source>java:comp/env/jdbc/MSSQL1</jta-data-source> --> 
     <class>com.model.DbLogTable</class> 
     <properties> 
      <property name="javax.persistence.jdbc.url" value="jdbc:weblogic:sqlserver://mssql1.xxx.xxx.xxx.com:1433;databaseName=mydb" /> 
      <property name="javax.persistence.jdbc.user" value="user" /> 
      <property name="javax.persistence.jdbc.driver" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" /> 
      <property name="javax.persistence.jdbc.password" value="pwd" /> 
     </properties> 
    </persistence-unit> 
</persistence> 

我的EJB模塊（消息驅動bean）部署在WebLogic Server上。我幾乎沒有使用過JPA/EJB3/Weblogic。所以可能是我犯了一個基本的錯誤，但我無法找到它。從錯誤中，我在persistence.xml中指定的驅動程序肯定是錯誤的，誰能告訴我應該指定什麼驅動程序？還有什麼我應該改變？

任何幫助，非常感謝。

哦該死..........我猜weblogic.jdbc.sqlserver.SQLServerDriver的作品。
