中文XML论坛--为什么我在create Hibernate mapping时会出现“在Generating artifacts期间发生了内部错误”这样一个错误?

贴子主题：为什么我在create Hibernate mapping时会出现“在Generating artifacts期间发生了内部错误”这样一个错误?

本主题类别:

今天是用Eclipse3.2+MyEclipse5.0+oracle9i，用Database Explorer创建Hibernate3所需的HBM映射文件和VO对象时，居然报An internal error occurred during: "Generating Artifacts" 这个错误。

请达人帮我看看怎么回事？我用的是驱动ojdbc14.jar(把ojdbc14.zip改后缀成ojdbc14.jar。不知道可不可以？)。

通过查看.metadata\.log文件发现出现如下错误提示:
org.hibernate.exception.GenericJDBCException: Could not get list of tables from database. Probably a JDBC driver problem.
Configured schema:HANCHAOMAN
Configured catalog:null   （这句话最可疑，但不知道什么意思？）
