【问题描述】：
我已经使用在 Tomcat 7.0.41 上运行的 hibernate 4.2.8 设置了一个 Web 服务。我使用 Postgres 9.2 数据库。
我创建了一个 Hibernate 用户类型来使用 Postgres 提供的点数据类型。首先，我尝试使用一个小型演示应用程序进行测试和使用，到目前为止一切正常。
当我在我的 Web 服务上尝试此代码时，它在尝试使用我的自定义类型插入一行时总是报告以下错误：

我使用的是相同的 DBS，但使用了不同的数据库，但两者都设置了 utf-8 字符编码
由于hibernate通过Tomcat提供的JNDI Ressource连接到数据库，我想Tomcat可能会破坏我的Insert语句。所以我删除了JNDI资源并直接连接到数据库，结果如下：

有人知道这可能是什么原因吗？由于重新配置数据库连接时错误发生了变化，我想这可能与 Tomcat 弄乱它有关。
