从java插入oracle中的数据有问题

Question

我在VM的服务器和客户端中都有centos6.4。我正在尝试从Java（java SE 8）在oracle 11gr2中存储一些值（jTextFieldBookID.getText（），jTextFieldBookName.getText（），jTextFieldCategory.getText（），jTextAreaDescription.getText（）和sqdate。）。但有数百个错误。我没有解决办法。

代码是：

tablebookmaster:-
SQL> desc tablebookmaster;
 Name                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 BOOKID                    NOT NULL NUMBER(38)
 BOOKNAME                           VARCHAR2(45)
 CATEGORY                           VARCHAR2(30)
 DESCRIPTION                        VARCHAR2(60)
 REGISTRYDATE                       DATE

ClassConnectDB文件：

package PackageInventory;

import java.sql.*;
import javax.swing.JOptionPane;


public class ClassConnectDB 
{


    public static Connection connectdb()
    {
        try
        {
            Connection conn = null;

            Class.forName("oracle.jdbc.driver.OracleDriver");
            conn =  DriverManager.getConnection("jdbc:oracle:thin:@serverora11gr2:1521:orcl","scott","tiger");


            return conn;
        }
        catch(Exception e)
        {
            JOptionPane.showMessageDialog(null, " exception in ClassConnectDB.connectdb() is :  " + e);
            return null;

        }
    }

}

        //sqdate = new java.sql.Date(udate.getTime());







        String sql = "insert into tablebookmaster values(?, ?, ?, ?, ?);";

        pst = conn.prepareStatement(sql);



        pst.setInt(1, Integer.parseInt(JTextfieldBookIdStr) );

        //JOptionPane.showMessageDialog(null,"

        pst.setString(2,JTextFieldBooknameStr);

        pst.setString(3,JTexTFieldCategoryStr);

        pst.setString(4,JtextAeraDesciptionStr);

        pst.setDate(5, sqdate);

        pst = conn.prepareStatement(sql);

        int inserted  = pst.executeUpdate();



        if(inserted == 1)

        {

            JOptionPane.showMessageDialog(null,"row inserted successfully");       

        }



        else

        {

            JOptionPane.showMessageDialog(null,"Sorry!. Your record has not saved");

        }



        conn.close();

   }

    catch(Exception e)

    {

           JOptionPane.showMessageDialog(null, "exception in jButtonSaveActionPerformed : " + e);



    }

}
