I want to make a gwt app with large number of concurrent users. Users
will run many queries. Shouldn't I keep the connection open in this
servlet so it can execute the queries faster like below? In the code
below, for every user accessing this servlet does it create a new
connection to the database or use one connection object in the servlet
scope? Or should I use connection pooling?
import java.sql.*;
public class GreetingServiceImpl extends RemoteServiceServlet
implements
GreetingService {
private Connection connection;
public GreetingServiceImpl(){
//Open the connection here
}
public String greetServer(String input) {
//Use the connection here
Statement stmt = connection.createStatement();
..<do JDBC work>..
}
}
