eclipse使用hibernate插件生成反向工程问题

 如果 hibernate的配置文件写成这样

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
  "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
  "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
        <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:ORCL</property>
        <property name="hibernate.connection.username">gisway</property>
        <property name="hibernate.connection.password">gisway</property>
               <property name="hibernate.default_schema">gisway</property>
        <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>
    </session-factory>
</hibernate-configuration>

红色部分. schema 小写的 schema 会造成 sys.log***什么什么表重复..要么没有.  如果改成 大写.就可以了 GISWAY
