单机情况下如何配置实用hibernate？
开发环境为JDK1.7+Hibernate3.5.3
hibernate.cfg.xml配置如下：
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/plib</property>
<property name="connection.username">root</property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- Enable Hibernate's automatic session context management -->
<property name="current_session_context_class">thread</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<!-- <property name="cache.use_second_level_cache">true</property>
<property name="cache.provider_class">org.hibernate.cache.EhCacheProvider</property> -->
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<!-- <property name="hbm2ddl.auto">create</property> -->
<mapping class="com.fd.plibmrg.model.Department"/>
<!--
<mapping class="com.fd.plibmrg.model.SourceCode"/>
-->
</session-factory>
</hibernate-configuration>
联网时可顺利通过测试，而使用代理上网（或不使用代理）时后台报错如下：

哪位大侠能详细描述如何在单机环境下使用hibernate，小弟在此不胜感激！！ 单机，hibernate
[解决办法]
没有dom4j.jar包？
