Neo4j的2.0.0 M3初始化失败

我已经使用在开发一个简单的Web应用程序的Neo4j 2.0.0 M3版本，在过去一个月左右的时间。直到今天，当我开始创建数据库时，我的版本完全没有问题。Neo4j的2.0.0 M3初始化失败

我有点新手和我有一个很难确定问题的确切原因是什么，以及如何去修复它。错误日志如下，我希望在解释输出时获得一些帮助。谢谢！

您正在使用什么版本的Java。你是否在使用Java 6运行它？ – Jatin

这可能是因为Neo4J的System Requirements。它说，你需要的Java 7

看起来你使用的是Java 6的这java.lang.ClassNotFoundException: java.nio.channels.SeekableByteChannel被抛出。使用Java 7应该可以解决这个问题。

谢谢Jatin。我可能应该自己想出了这件事，但无论出于何种原因，直到今天它已经在Java 6中正式发布了。 – bornytm
