I have an application usig JSF + Spring. At the start I was using hard-coded DAO objects to access EIS layer. Then i decided to move to Hibernate, using Spring's templates. The fact is that when i use Hibernate, the application does not work, there's an error which causes my backing beans in the presentation layer fail. I have made some debuging, and came to the conclusion that this line (present in all backing beans) is the one causing troubles.

appContext = WebApplicationContextUtils.getRequiredWebApplicati onContext(context);

The application context xml file is:

Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http&#58;//www.springframework.org/dtd/spring-beans.dtd">

Notice that the application works well with the next context:

Code:
