用Java格式化结果集

我需要格式化从JDBC获得的结果集

有没有我用的现成包装

我在上面的网站上看到了它，但不知道如何获取jar文件

package mysql.first;

  public static void main(String[] args) throws Exception {
      MySQLAccess dao = new MySQLAccess();
        //dao.readDataBase();
        dao.createtemptable();
  }

  public void createtemptable() throws Exception{
      try
      {
          // This will load the MySQL driver, each DB has its own driver
          Class.forName("com.mysql.jdbc.Driver");
          // Setup the connection with the DB
          connect = DriverManager

                  + "user=sqluser&password=sqluserpw");

          connect.setAutoCommit(false);

          // Statements allow to issue SQL queries to the database
          statement = connect.createStatement();

-1对于effortI的lact，在下载文件后，我导入了我的Java项目中的所有jar文件..导入com.hp.hpl.jena.query.*；是成功的，但是在我的程序中用我的一个方法引用类ResultSetFormatter时，它失败了…我的经验非常少，所以你必须忍受me@ay89-上面说ResultSetFormatter无法解析..我已经在上面附加了我的代码
