--  请教Jena中怎么建立实例（已经将本体倒入了数据库）
请教各位大虾：
我已经将在protege中建立好的本体倒入了MySql数据库中，同时看到了七张表，都是以Jena开头的
我现在有几个疑问：
第一：这几张表表示什么意思？
第二：为什么表里面没有数据？（应该有如类的信息吧）
第三：我如何在Jena里建立实例呀？
谢谢了

po.listClasses(maker, s_source);

这个运行结果怎么样？类都列出来了吗？

就是没有呀，在那几个表里面什么数据都没有，觉得有点奇怪了！

OntDocumentManager.getInstance().addAltEntry(ONT1, "http://www.owl-ontologies.com/travel.owl");

改成本地地址看看。

这个本体现在网上没有啊，你有没有映射到本地文件啊？

呵呵，再次谢谢你的帮助！
那个本体我是从网上下的，我已经下载到了本地，后来也改了本地地址。
http://www.owl-ontologies.com/travel.owl，这是它的命名空间。
后来我想干脆直接赋初值给s_source（取得本地地址，如file：F：/travel.owl）,后面的那个私有方法也就没用了，程序如下：但是还是看不到本体的任何内容。

能把你的travel.owl传上来吗？
没有本体文件，我不好帮你调程序啊

太谢谢你了！呵呵！
你是说travel.owl文件吧，不好意思，因为我看不到你给我的回帖，呵呵，很奇怪，只在首页能看到你的最后跟帖，但是看不到详细内容，我猜的。
