Neo4j服務器未啓動：

我正在使用Neo4j 2.3.0-M03社區版本。我已經使用neo4j導入工具創建了一個數據庫。現在，當我要啓動neo4j服務器時，它的失敗。有什麼建議？提前致謝！Neo4j服務器未啓動：

啓動Neo4j服務器...警告：不會更改用戶進程[21597] ...等待服務器準備就緒.........在120秒內無法啓動。 Neo4j服務器可能啓動失敗，請檢查日誌。

的日誌如下：

好像在Neo4j的安裝目錄下的lib文件夾一些權限問題。嘗試給neo4j安裝文件夾提供完整權限。

也建議使用穩定版本而不是里程碑版本。

感謝您的建議。但在我嘗試使用Traversal API在我的數據庫上實現BFS遍歷之前，它工作正常。我在我的jdk lib文件夾中創建了Neo4j庫文件的軟鏈接，以便讓它們在我的應用程序中可見。然後我的代碼運行良好，從數據庫中獲取遍歷路徑。但是，當我再次嘗試運行服務器以嘗試Neo4j-shell中的某些密碼時。它給這個錯誤。 –

我可以修復它。我的嵌入式數據庫出現了一些問題。我試圖用默認的graph.db運行服務器，並且運行成功。現在我必須確定使用導入工具創建的嵌入式數據庫有什麼問題。
