Neo4j服务器未启动：

我正在使用Neo4j 2.3.0-M03社区版本。我已经使用neo4j导入工具创建了一个数据库。现在，当我要启动neo4j服务器时，它的失败。有什么建议？提前致谢！Neo4j服务器未启动：

启动Neo4j服务器...警告：不会更改用户进程[21597] ...等待服务器准备就绪.........在120秒内无法启动。 Neo4j服务器可能启动失败，请检查日志。

的日志如下：

好像在Neo4j的安装目录下的lib文件夹一些权限问题。尝试给neo4j安装文件夹提供完整权限。

也建议使用稳定版本而不是里程碑版本。

感谢您的建议。但在我尝试使用Traversal API在我的数据库上实现BFS遍历之前，它工作正常。我在我的jdk lib文件夹中创建了Neo4j库文件的软链接，以便让它们在我的应用程序中可见。然后我的代码运行良好，从数据库中获取遍历路径。但是，当我再次尝试运行服务器以尝试Neo4j-shell中的某些密码时。它给这个错误。 –

我可以修复它。我的嵌入式数据库出现了一些问题。我试图用默认的graph.db运行服务器，并且运行成功。现在我必须确定使用导入工具创建的嵌入式数据库有什么问题。
