servlet与javabean实现长文本数据分页显示

这是做wap的时候碰到的问题,您碰到类似的问题可以参考一下！
javabean文件:
DataConnection.java;//数据库连接
BasicInfo.java;//数据bean容器
DataWork.java;//数据操作
servlet文件:
OrderInfoServlet.java;//servlet实现长文本数据分页显示
xml配置文件:
web.xml;//servlet配置

DataConnection.java文件内容为：

package wap_cctv_film;

import java.sql.*;

public class DataConnection {

  public static Connection getDataConnection() {
    Connection conn = null;
    try {
      Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
      conn = DriverManager.getConnection("jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=wapvod","cctv_sql_user","cctv_sql_user");
    }
    catch (Exception ex) {
      ex.PRintStackTrace();
    }
    return conn;
  }
}

BasicInfo.java文件内容：

package wap_cctv_film;

import java.io.*;

public class BasicInfo
    implements Serializable {
  private String basicName;
  private int basicHits;
  private int basicID;
  private String basicText;
  private int basicIsShow;
  private int basicType;
  public String getBasicName() {
    return basicName;
  }

  public void setBasicName(String basicName) {
    this.basicName = basicName;
  }

  public int getBasicHits() {
    return basicHits;
  }

  public void setBasicHits(int basicHits) {
    this.basicHits = basicHits;
  }
  public int getBasicID() {
    return basicID;
  }
  public void setBasicID(int basicID) {
    this.basicID = basicID;
  }
  public String getBasicText() {
    return basicText;
  }
  public void setBasicText(String basicText) {
    this.basicText = basicText;
  }
  public int getBasicIsShow() {
    return basicIsShow;
  }
  public void setBasicIsShow(int basicIsShow) {
    this.basicIsShow = basicIsShow;
  }
  public int getBasicType() {
    return basicType;
  }
  public void setBasicType(int basicType) {
    this.basicType = basicType;
  }

}

DataWork.java文件内容：

package wap_cctv_film;

import java.sql.*;
import java.util.*;

public class DataWork {
  private Connection conn;
  public DataWork() {
