How to receive data via sockets retrieved through Result Set?

Question

Statement st=(Statement) sqlcon.createStatement();
ResultSet p=st.executeQuery("SELECT * FROM `chat`.`online_users`");

I have got the data from the database through the object of ResultSet but when i am sending it to the client through sockets it is giving an error. It is not serializable. How to send data and receive data retrieved through ResultSet across socket?

Answer 1

Read the data from the ResultSet , push it in a List then send your List . All the implementations like ArrayList already implement Serializable interface, you can read this answer to know more about List Serialization.

Answer 2

Well, you could inherit from ResultSet and implement Serializable interfaces in a new class. I would suggest a better approach would be to send XML between layers, or if you want an all Java solution, how about creating an object for each row, stuffing them in a collection class or vector, and serializing it instead of the ResultSet class.

Answer 3

由于它需要可序列化并通过网络连接发送，因此CachedRowSet似乎是您尝试的不错选择。
