I'm using Spring MVC (3.0) with annotation-driven controllers. I would like to create REST-ful URLs for resources and be able to not require (but still optionally allow) file extension on the end of the URL (but assume HTML content type if no extension). This works out-of-the-box with Spring MVC as long as there are no dots (period/full-...

Hi, I am working on a web application. We are using jasperreports. Compiling jasperreports on every call is an overhead and takes considerable time (4-7 seconds). We thought of precompiling the jrxmls using Spring but still have the ability to re-generate if the jrxml is changed/modified. Has anybody done this before? If yes, how. Thanks...

Since all pages will potentially use the same recordset every time I could store the countrylist as a List in some global bean, safe in this case. I could manage to refresh the list any time I want... but when things become more complex what is the best strategy for it...
Hi, I've got a web app with Spring set up to create my hibernate session factory (singleton) and session and transaction (both are request scoped), but it is destroying the session and transaction in the wrong order.

Spring does DI and creates objects so that your program need not worry of creating objects. But the question here is when an instance of injected object is created. Is it when the main program makes use of the instance or at the time an instance of main program is created. ...
Hi, i'm developing an application using Wicket as the view layer and JPA(Hibernate) as ORM. building the UI has been fun (even with ajax) using Wicket. My problem comes from integrating the persistent objects on edit pages (readonly pages are no problem using a LoadadableDetachableModel). I'm using the OSIV filter from spring to provide...
I have seen that I can add errors and render them via <form:errors /> tag and addError() method of BindingResult class, but I wonder if there is something similar to send information messages to the JSP. I mean, I want to add messages when the operation has been successful. I know I could do it by sending an error, but it would make no ...
I have a data structure representing a CSV file containing thousands of config settings.

These classes are not created by Spring as they have state. I would like the class t...

I am building a spring mvc web application. I plan on using hibernate. I don't have much experience with obfuscating etc. What are the potential downsides to obfuscating an application? I understand that there might be issues with debugging the app, and recovering lost source code is also an issue. Are there any known issues with the...
