hibernet tools使用问题请教

[软件搬运工]

数据库连接信息如下:
<?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 name="MGRSYS">
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.password">MGRSYS</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@10.148.35.222:1521:MGRSYS</property>
<property name="hibernate.connection.username">MGRSYS</property>
<property name="hibernate.default_schema">MGRSYS</property>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>
</session-factory>
</hibernate-configuration>

在建立表的mapping时候，无法找到数据库的Table Schema，即找不到任何表。我连接其它数据可以看到，就是刚建立的数据库不行（新建立了两个数据库都不行）。
控制台会出现这个错误：2012-02-05 10:21:15,093 WARN Worker-4 org.hibernate.impl.SessionFactoryObjectFactory - Could not bind factory to JNDI
