我有以下Java代码.此代码的目的是建立连接
到远程MySQL数据库ProductionDb(我的/etc/odbc.ini文件中定义的数据源).

import java.sql.*;
import java.util.*;
import java.io.*;

public class Test {

    public static void main(String[] args) {

        try {
            Connection conn = null;
            PreparedStatement s = null;
            String driver = "sun.jdbc.odbc.JdbcOdbcDriver";

            Class.forName(driver).newInstance();
            conn = DriverManager.getConnection("jdbc:odbc:ProductionDb");

        } catch (Exception ex) {
            System.out.println(ex.getMessage());
        }
    }

}

/etc/odbc.ini文件是：

$cat /etc/odbc.ini
[ProductionDb]
Driver = /usr/lib/odbc/libmyodbc.so
Description = Production Database
Server = [ hidden ] 
Port = 3306
User = [ hidden ] 
Password = [ hidden ] 
Database = ProductionDb

顺便说一下 – 我使用的是Java 7和Ubuntu：

 $java -version
    java version "1.7.0_09"
    Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
    Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02,mixed mode)

 $lsb_release -a
    No LSB modules are available.
    Distributor ID: Ubuntu
    Description:    Ubuntu 11.04
    Release:    11.04
    Codename:   natty

当我尝试运行我的程序时,我收到以下错误：

$java Test
java: symbol lookup error: /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libJdbcOdbc.so: undefined symbol: sqlAllocEnv
@H_502_9@
有谁知道我为什么会收到这个错误？
这有什么不对？
P.S顺便说一下我运行sudo apt-get install unixodbc-dev,sudo apt-get install libmyodbc和sudo apt-get install libMysqL-java
