I'm looking to identify each computer that accesses my website independent of cookies. I know it can be done because Twitter does it. Here's proof: Reset a browser (no cookies, no cache, total reset) Visit twitter.com Note the value of newly added _twitter_sess cookie Repeat Steps 1 - 3. Cookie _twitter_sess will have the same value as before Change IP addresses Repeat Steps 1 - 3. Cookie _twitter_sess will have the same value as before Change Browsers Repeat Steps 1 - 3. Cookie _twitter_sess will have the same value as before Change User Agents Repeat Steps 1 - 3. Cookie _twitter_sess will

I'm new to this forum and also new to JPA / EJB. I'm trying to deploy a .war file containing a small application to a tomcat server. The application is using JTA to communicate with the Derby db. When I run and deploy the application from and eclipse top the tomcat server running in eclipse, everything works perfect, but when I export a .war file and try to browse the application it throws an java.lang.ClassNotFoundException: javax.persistence.PersistenceException. My persistence file looks like this: <?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns

I am getting org.hibernate.LazyInitializationException: illegal access to loading collection in my JPA code - all collections are EAGER fetch - when the collection entity also has a collection. Could somebody please help me to fix this? I have isolated a problem in my JPA code to the following @Entity definitions: (note, I'm skipping the package and import statements to shorten the code. Some Lombok annotations are used, such as @Data to mean that the field has a getter/setter and @Cleanup to do the usual try/catch close() dance) @Entity @Data public class MyEntity implements Serializable {

I have a timestamp column tradedate in one of the DB(Oracle) tables. I am using hibernate as the persistence layer to fetch and store Data to DB. I have a requirement in which I need to query the DB on date. i.e From UI the user passes a date and I need to get the filtered data based on this date. If the tradedate column only has the date part my query returns the correct records The issue arises when the tradedate column is populated with a timestamp value ie(date + time). Then those values are not returned by the query. eg:say there are 10 records for 23rd Oct 2010 in DB 5 of them have the

Currently I am using ViewData or TempData for object persistance in my ASP.NET MVC application. However in a few cases where I am storing objects into ViewData through my base controller class, I am hitting the database on every request (when ViewData["whatever"] == null). It would be good to persist these into something with a longer lifespan, namely session. Similarly in an order processing pipeline, I don't want things like Order to be saved to the database on creation. I would rather populate the object in memory and then when the order gets to a certain state, save it. So it would seem
