解决方案 »

  1.   

    root causejavax.servlet.ServletException: java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver数据库驱动没加，或者没有import进来
      

  2.   

    class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 试一下。
      

  3.   

    com.microsoft.sqlserver.jdbc.SQLServerDriver
    还有检查一下你的驱动包添加了没？
      

  4.   

    com.microsoft.jdbc.sqlserver.SQLServerDriver驱动的问题，没有找到驱动包啊
      

  5.   

    你的JDBC驱动JAR未加入项目的classpath里
      

  6.   

    import 下驱动包，右键项目，build path
      

  7.   

    java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver
    你的项目构建路径中没有SQL的驱动包...
