在JSF 网页中，连接数据库类问题

[Robinfu2013]

import java.sql.*;
import javax.servlet.jsp.jstl.sql.Result;
import javax.servlet.jsp.jstl.sql.ResultSupport;
public class Connection {
String sDBDriver = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
String sConnStr = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=Bank;";
Connection connect = null;
public Connection() {
try
{
Class.forName(sDBDriver);
}catch (java.lang.ClassNotFoundException e )
{
System.err.println(e.getException());
}
try
{
connect = DriverManager.getConnection(sConnStr,"sa","");
}catch(SQLException ex)
{
System.err.println();
}
}
}
红色的字体上面提示我"Connection.java": incompatible types; found : java.sql.Connection, required: icbc.Connection at line 20, column 37
我以前也是这样用，这次怎么提示出错了呢？这个类用作连接数据库
