這是我試過的代碼。

ODatabaseDocumentTx db = new ODatabaseDocumentTx("plocal:F:/Program Files/orientdb-community-2.2.0/databases/mydbo").open("admin", "admin"); 

ODocument doc = new ODocument("Person"); 
doc.field("name", "Luke"); 
doc.field("surname", "Skywalker"); 
doc.field("city", new ODocument("City").field("name","Rome").field("country", "Italy")); 


doc.save(); 
db.close();

我不能找出我有錯誤。請幫助我

您有一臺服務器正在運行，您嘗試從另一個進程中以plocal打開數據庫。請確認您在使用plocal（控制檯或外部進程）訪問它時沒有活動的OrientDB實例，並且您一次打開一個plocal連接？
