无法连接到Firebird（Ubuntu）

我是Ubuntu的新手，我只是把它安装在电脑上。 我安装了Samba并共享了文件夹“/ samba”和“/ hd”。 我下载并安装了Firebird，并复制了我在Windows上创build的数据库，并将其放入“/ samba”中。 这是我的Java代码：

public static Connection getConnection() throws SQLException { Connection connection = null; try { Class.forName("org.firebirdsql.jdbc.FBDriver"); } catch (ClassNotFoundException e) { throw new RuntimeException(e); } connection = DriverManager.getConnection("jdbc:firebirdsql://localhost:3050/samba/LNX.FDB", "sysdba", "masterkey"); return connection; } public static void main(String[] args) throws SQLException { getConnection(); } 

我得到这个错误：

 Exception in thread "main" org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544344. I/O error during "open" operation for file "samba/LNX.FDB" Error while trying to open file null at org.firebirdsql.jdbc.FBDataSource.getConnection(FBDataSource.java:120) at org.firebirdsql.jdbc.AbstractDriver.connect(AbstractDriver.java:136) at java.sql.DriverManager.getConnection(DriverManager.java:571) at java.sql.DriverManager.getConnection(DriverManager.java:215) at br.com.ipsnet.jdbc.ConnectionFactory.getConnection(ConnectionFactory.java:16) at br.com.ipsnet.jdbc.ConnectionFactory.main(ConnectionFactory.java:22) Caused by: org.firebirdsql.gds.GDSException: I/O error during "open" operation for file "samba/LNX.FDB" Error while trying to open file null at org.firebirdsql.gds.impl.wire.AbstractJavaGDSImpl.readStatusVector(AbstractJavaGDSImpl.java:2098) at org.firebirdsql.gds.impl.wire.AbstractJavaGDSImpl.receiveResponse(AbstractJavaGDSImpl.java:2048) at org.firebirdsql.gds.impl.wire.AbstractJavaGDSImpl.internalAttachDatabase(AbstractJavaGDSImpl.java:463) at org.firebirdsql.gds.impl.wire.AbstractJavaGDSImpl.iscAttachDatabase(AbstractJavaGDSImpl.java:411) at org.firebirdsql.jca.FBManagedConnection.<init>(FBManagedConnection.java:105) at org.firebirdsql.jca.FBManagedConnectionFactory.createManagedConnection(FBManagedConnectionFactory.java:509) at org.firebirdsql.jca.FBStandAloneConnectionManager.allocateConnection(FBStandAloneConnectionManager.java:65) at org.firebirdsql.jdbc.FBDataSource.getConnection(FBDataSource.java:118) ... 5 more 

如果我去“/ samba”并input：

 isql-fb connect "localhost:/samba/LNX.FDB" user 'SYSDBA' password 'masterkey'; 

它工作得很好，我可以select，删除，更新，插入，…没有任何问题。

• 在HBASE中创build表时，类未findexception
• 使用start-stop-daemon无法在Linux中停止Java服务
• Java Swing显示停止更新，直到生成X事件
• Shell脚本导入mysql转储文件
• 是否有任何Java库来调整Linux上的IO调度优先级

如果我在Windows机器上使用IBExpert连接到Ubuntu中的数据库，它会显示：

 Unable to complete network request to host "Server-Test". Failed to estabilish connection. 

如果我使用Flamerobin，它说：

 An assertion failed! ../src/common/strconv.cpp(3031): assert "Assert failure" failed in wxCSConv(): invalid encoding value in wxCSConv ctor 

但它连接。 我可以select，删除，更新，…
