sqlite打开db：'。/ sqlite.db'：权限被拒绝

Question

我正在使用Jersey制作一个安静的应用程序，我正在使用Hibernate来管理我的Web服务的持久层，目前我使用的是Postgresql，但现在我想将Postgresql更改为嵌入式SQLite，但是我在初始化时遇到以下错误：

1    [localhost-startStop-1] ERROR org.hibernate.tool.hbm2ddl.SchemaExport  - schema export unsuccessful

我正在尝试创建sqlite.db但许可被拒绝。如何解决这个问题的任何线索？

PD：这是persistence.cfg.xml

编辑：我发现当persistence.cfg.xml有： <property name="connection.url">jdbc:sqlite:./sqlite.db</property>

sqlite选择的路线是下一个：C:\WINDOWS\system32\.\sqlite.dband显然没有权限访问那里...

Answer 1

解决。

问题是由于我在Eclipse中运行Tomcat，默认情况下它显示了C：\ WINDOWS \ system32，当我在Eclipse外部的Tomcat中运行Web服务时效果很好。
