使用middlegen产生hibernate映射文件的问题

来源：百度知道 编辑：UC知道 时间：2024/05/15 00:45:27
middlegen工具能根据接入的数据库表产生hbm映射文件，这好像跟用不用jboss没关吧？我根据网上的middlegen+hibernate配置教程（如http://farien.meimeiblog.com/blog/janlon/3498/），成功连入数据库，但是出现如下错误：

fail-if-not-jboss-home-present:
[echo] Directory for jboss.home = ${jboss.home} not found
[echo] You have to specify the home directory for JBoss in an ant property named jboss.home
[echo] You can do this by defining D:\Documents and Settings\jovi\Desktop\middlegen-2.1\samples/build.properties or in D:\Documents and Settings\jovi/build.properties

请高手解答一下这是怎么回事，这与jboss何关？

ialect does not support sequences
at net.sf.hibernate.dialect.Dialect.getSequenceNextValString(Dialect.java:319)

我的 tableName.hbm.xml是这样的：
...
<id name="id" column="MESSAGE_ID">
<generator class="sequence">
<param name="sequence">SEQ_message_id</param>
</generator>
</id>
...
我的hibernate.cfg.xml是这样的：
