Q:

Java Web Project connection with Jsp and Servlet

I am new to Java web project and am using Jsp and Servlet in it, in order to connect with the database my each and every jsp file is making a new JDBC connection and connecting through it.
Is there any other way I can have a common place for JDBC connection and through that I can communicate with Database?

A:

For simple non-production projects,
public class DatabaseConnection{
    private static Connection conn = new Connection(db conn properties);

    public static Connection getConnection(){
         return conn;
    }
}

Wherever you need database connections, use 
DatabaseConnection.getConnection()

If you want things like stale condition check etc etc. go for a connection pool. As it would be faster and better to include a open source connection pool than implementing these features manually.
For production environments, you can use Connection Pools like c3p0, hikariCP
