我正在尝试使用JDBC连接到SQL Server 2008。我的SQL Server 2008带有Windows身份验证。

我的代码是

public class T1 {

/**
 * @param args
 */
private static void Connect(){
    try
    {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        String connectionUrl =        "jdbc:sqlserver://servername;databaseName=employee;user=username;password=''/*since it is windows authentication*/;";
        java.sql.Connection con = DriverManager.getConnection(connectionUrl);
    }
    catch(ClassNotFoundException e)
    {
        e.printStackTrace();
    }
    catch(SQLException e2)
    {
        e2.printStackTrace();
    }
}


public static void main(String[] args) {
    // TODO Auto-generated method stub

    T1.Connect();

}

我最终得到ClassNotFoundException。

堆栈跟踪为 java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source)
