I'm designing a new app based on JPA/Hibernate, Spring and Wicket. The distinction between the DAO and Service layers isn't that clear to me though. According to Wikipedia, DAO is an object that provides an abstract interface to some type of database or persistence mechanism, providing some specific operations without exposing...
I have an application which uses Spring 2.5 and Hibernate 3. There's a web application with a presentation layer, a servive layer and a DAO layer, as well as some Quartz jobs sharing the same service and DAO layers. Transactions are initialized in different layers with @Transactional annotations, like this: It led me to a problem ...
I have a Spring MVC app that does not protect updates of user data with transactions. It assumes that only a single user is accessing the account data for that account at any one time. However, if two users were to log in using the same authentication credentials, it is theoretically possible, although unlikely, for two database upda...

In class we're now learning how to build up a Spring application, even though spring isn't directly involved, we learned how to make the interfaces for DAO and service layer objects. Please correct me if I'm wrong: DAO layer is pretty abstract: it just contains the CRUD operations and is further used to read data.(ie: get all objects, ...
I would like to display the currently running version of my web application in the page. The project is based on Maven, Spring, and Wicket. I'd like to somehow get the value of maven's ${project.version} and use it in my spring XML files, similarly to the way I use the Spring PropertyPlaceholderConfigurer to read a property file for set...
Firstly it is possible that I am asking something that has been asked and answered before but I could not get a search result back .

We are seeing Spring in school right now but we don't have the time to wait till the end of the semester to start developing an application. We continue using an app we made last year, and are writing the service layer right now. The problem is our "client" wants to have a desktop client and a webpart, which used the same dtatabase. Thi...
Our project has just decided to migrate from Spring 2.5.5 to Spring 3.0.4.
