Neo4j的2.0.0 M3初始化失敗

我已經使用在開發一個簡單的Web應用程序的Neo4j 2.0.0 M3版本，在過去一個月左右的時間。直到今天，當我開始創建數據庫時，我的版本完全沒有問題。Neo4j的2.0.0 M3初始化失敗

我有點新手和我有一個很難確定問題的確切原因是什麼，以及如何去修復它。錯誤日誌如下，我希望在解釋輸出時獲得一些幫助。謝謝！

您正在使用什麼版本的Java。你是否在使用Java 6運行它？ – Jatin

這可能是因爲Neo4J的System Requirements。它說，你需要的Java 7

看起來你使用的是Java 6的這java.lang.ClassNotFoundException: java.nio.channels.SeekableByteChannel被拋出。使用Java 7應該可以解決這個問題。

謝謝Jatin。我可能應該自己想出了這件事，但無論出於何種原因，直到今天它已經在Java 6中正式發佈了。 – bornytm
