Re: [Springframework-developer] interface21 Properties editor in BeanWrapperImpl

This problem might occur depending on the security policy setting on the 
JVM on which your app server is running. If you making  the appropriate 
JVM setting this problem will be solved.

Hope this helps

I don't understand why com.interface21.beans.propertyeditors.PropertiesEditor doesn't get registered automatically in your case... It definitely does on my installation (with a current Spring version).

It addresses every tier - data access, services, and web - in a reusable and flexible fashion. I particularly like its modularity: You can choose to use Struts for the web tier but use a Spring ApplicationContext for your services layer, for example - without any hassle. Or just use Spring JDBC in a project, using whatever you like for the rest of your infrastructure.

Recent developments include pluggable transaction management and AOP support. Ease of use and separation of concerns are central ideas, to allow for applications that consist of clearly separated layers instead of being web-centric. This enables reuse not only across various server applications with or without web layer but also including standalone applications.

For example, compare the validation support: Struts' is tied to ActionForms while Spring's isn't tied to web classes at all. Generally, Struts' API has some major design flaws that make it inflexible and not suitable for fine-grained reuse of application logic. It provides a lot features for web apps, though, especially in release 1.1.

It is built in a very flexible way, allowing for writing on controllers on any level you choose, be it Controller at the HttpServletRequest level, CommandController at the populated command level, or FormController at the form handling level. Even beyond that, you can customize mapping strategies, view resolution, etc. This is very different to Struts that just offers one single level of controller implementation, and no fine-grained customization hooks.

The latter project is currently in the business logic phase, using Spring for context infrastructure and configuration (providing a unit test environment with minimal effort), and Hibernate for O/R mapping. At the moment, there isn't even a J2EE container involved, just a simple test environment with mock JNDI and a mock JDBC DataSource! The project will use Spring's web MVC support in the UI phase (beginning soon) - then we will switch to a J2EE container seamlessly.
