我想从NetBeans编写的Java代码中连接远程Sybase.到目前为止,我已经准备了如下代码:
public static void connect()
{
String host = "192.168.150.11";
String url = "jdbc:sybase:Tds:"+host+":4100";
String username = "sa";
String password ="";
SybDriver sybDriver = null;
Connection conn;
try
{
sybDriver=(SybDriver)Class.forName("com.sybase.jdbc3.jdbc.SybDriver").newInstance();
System.out.println("Driver Loaded");
conn = DriverManager.getConnection(url,username,password);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from zxdbl_888..account_0");
rs.next();
System.out.println(rs.getString(2));
}
catch (InstantiationException ex)
{
Logger.getLogger(Offline_charge.class.getName()).log(Level.SEVERE, null, ex);
}
catch (IllegalAccessException ex)
{
Logger.getLogger(Offline_charge.class.getName()).log(Level.SEVERE, null, ex);
}
catch (ClassNotFoundException ex)
{
Logger.getLogger(Offline_charge.class.getName()).log(Level.SEVERE, null, ex);
}
catch (SQLException ex)
{
Logger.getLogger(Offline_charge.class.getName()).log(Level.SEVERE, null, ex);
}
}
我得到的错误是:
java.lang.ClassNotFoundException: com.sybase.jdbc3.jdbc.SybDriver
我已经加载了jconn3.jar库.
解决方法:
通过Java应用程序安装Sybase驱动程序.
