Question

I have two classes(Pojos) name Soldbookdetails.java and Bookdetails.java,
what I want to do is, I have to get data from Bookdetails table(Soldbookdetails.java) and save the same data to my Soldbookdetails table(Soldbookdetails.java).

ActionClass.java

private Double[] id;//With getter and setter
private Double[] quantity;  //With getter and setter
Bookdetails book=new Bookdetails();//pojos,//With getter and setter
Soldbookdetails sbook=new Soldbookdetails();//pojos,//With getter and setter 
BookdetailsDAO dao=new BookdetailsDAO(); 
SoldBooksTransactionDAO dao2=new SoldBooksTransactionDAO(); 
------------

(Note: my both pojo are same only their Class name are different)

My problem: I am unable to save record from Bookdetails.java to Soldbookdetails.java .(See My above ActionClass.java class,inside the execute method , i have mention the ERRROR).

After getting record by Bookid , i am unable to save the record into my Soldbookdetails.java.

Please help me to solve my problem.

Answer 1

Your saveSoldbooks(Soldbookdetails s) method takes an object of Soldbookdetails as argument but you are passing an object of class Bookdetails.

The thing you can do is you can add a method that copies the attributes of an Bookdetails object to an Soldbookdetails object (without the id field). Then you should try to save the object of Soldbookdetails using your existing method.
