Question

My client first creates a url object with the url of the server (containing the servlet) and sends data to the servlet using the following code:

URL url = new URL("http://localhost:8080/hello");
    URLConnection connection = url.openConnection();
    connection.setDoOutput(true);

    ObjectOutputStream out=new ObjectOutputStream(connection.getOutputStream());
    out.writeObject(stringToReverse);

After receiving the required data from the server, the client again needs to send a data to the servlet. Should I close the above ObjectOutptStream and create a new one within the same connection to send the data? How should it be done?

Another question that I have is that each time I write data into the outputstream of the client, should I create a separate ObjectInputStream in the servlet?

Answer 1

Since these are all specific to a connection that ends as soon as the data is sent, I would suggest just instantiating them each time you make a connection. These objects are initialized using constructors instead of setter methods, and this suggests that the classes were not intended to be reused over and over again..
