java - sqlite 打开数据库 : './sqlite.db' : permission denied

Question

我正在使用 Jersey 制作一个 Restful 应用程序，我正在使用 Hibernate 来管理我的 Web 服务的持久层，目前我正在使用 Postgresql，但现在我想将 Postgresql 更改为嵌入式 SQLite，但我得到以下信息初始化错误:

我正在尝试创建 sqlite.db但许可被拒绝。关于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选择的路由是下一条:C:\WINDOWS\system32\.\sqlite.db显然没有权限访问那里...

Answer 1

已解决。

问题是由于我在 Eclipse 中运行 Tomcat，默认情况下它显示 C:\WINDOWS\system32 ，当我在 Eclipse 之外的 Tomcat 中运行 Web 服务时，它运行良好。
