我正在使用下面的代码从 servlet 连接到 SQL Server 2005 数据库。但它抛出了以下异常：

java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver

代码片段：

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

import javax.servlet.*;
import javax.servlet.http.*;

public class InsertServlet extends HttpServlet
{
public void doPost(HttpServletRequest request,HttpServletResponse response)
throws ServletException,IOException
{
    doGet(request,response);

}

public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException,IOException
{
    response.setContentType("text/html");
    PrintWriter pw=response.getWriter();
    EmpDetailBean empdetailbean=new EmpDetailBean();
    Connection con=null;
    PreparedStatement pstmt2=null;
    //ResultSet rs=null;
    String employeecode=request.getParameter("employeecode");
    pw.println(employeecode);
    empdetailbean.setEmployeecode(employeecode);
    try
    {   //String emp_code=(String)session.getAttribute("empcode");
        //Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        //String url = "jdbc:sqlserver://localhost;" +  
               // "databaseName=test;user=sa;password= ;"; 

        //con=DriverManager.getConnection("Jdbc:Odbc:leave1");
        con=DriverManager.getConnection("jdbc:sqlserver://10.217.7.3;databaseName=test;user=sa;password=123;");
        String query1="insert into leavetype(dbo.empcode) values(?)";

        pstmt2=con.prepareStatement(query1);
        pstmt2.setString(1,empdetailbean.getEmployeecode());

        int k=pstmt2.executeUpdate();
        System.out.println(k);
        pstmt2.close();    

    }
    catch(Exception e)
    {   pw.println("exception"+ e);

    }


}

}

如果您想com.microsoft.sqlserver.jdbc.SQLServerDriver用作驱动程序，则sqljdbc.jar需要存在于您的类路径中，即WEB-INF\lib.

如果您想使用 Jtds 驱动程序，请检查此链接以获取驱动程序和数据库 URL

似乎您已部署的 war 文件中缺少 JDBC 连接的 Jar 文件。你能确保lib文件与war文件正确打包吗
