Java 使用JPA/Hibernate和Jasypt进行配置

我试图在JSF/Primefaces项目中使用JPA+Hibernate4.5.1。我正在使用c3p0进行连接池。当应用程序启动时，c3p0尝试初始化池，但身份验证失败

这是我的persistence.xml：

    <persistence-unit name="ba">

    <properties>
        <property name="hibernate.connection.driver_class" value="net.sourceforge.jtds.jdbc.Driver"/>
        <property name="hibernate.connection.url" value="jdbc:jtds:sqlserver://x.x.x.x:1433/ba"/>
        <property name="hibernate.connection.username" value="ba"/>
        <property name="hibernate.connection.password" value="ENC(UcsChwXw5vYnM7w2S9XUaw==)" />            
        <property name="hibernate.connection.provider_class" value="org.jasypt.hibernate4.connectionprovider.EncryptedPasswordC3P0ConnectionProvider"/>
        <property name="hibernate.connection.encryptor_registered_name" value="configurationHibernateEncryptor"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>  
        <property name="hibernate.connection.release_mode" value="on_close"/>
        <property name="hibernate.archive.autodetection" value="class, hbm"/>
        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.c3p0.validate" value="true"/>
        <property name="hibernate.c3p0.min_size" value="5"/>
        <property name="hibernate.c3p0.max_size" value="20"/>
        <property name="hibernate.c3p0.timeout" value="8"/>
        <property name="hibernate.c3p0.max_statements" value="50"/>
        <property name="hibernate.c3p0.preferredTestQuery" value="SELECT 1;"/>
        <property name="hibernate.c3p0.idle_test_period" value="5"/>  
        <property name="hibernate.c3p0.idle_test_period" value="1200"/>
        <property name="hibernate.c3p0.acquire_increment" value="1"/>
    </properties>

</persistence-unit>

}

以下是“错误”行：

为了修复它，必须根据链接中提供的详细信息修改Jasypt-hibernate4提供的一个文件（EncryptedPasswordC3P0ConnectionProvider）

日志上写了什么？到底是什么错误？@snow8261，请检查更新。
