Enterprise Java productivity is still not ideal?

Spring community say that enterprise Java productivity is still not ideal. Why not? To start up the project you use code from previous projects or some assets. They are not ideal for new project. But why new Spring framework Roo provide ideal assets? There are exist many applications with designers just click and you have final applications. Such as WebSphere and AquaLogic. But still many developers and companies prefer use spring, ejb. This tools are more flexible. And actually I like idea of Spring Community. But Roo is still a toy. And I am afraid of automatically generated aspects. Last year innovations in enterprise application developing to create productive application with best practices is agile and cloud computing. I think it's quit interesting to have tool for manual coding and customization. We are going to the past no UI designers only command line. It's still flexible and fast solution.

Java future

Java future is abstract. But I think with time Java world would be stronger. I like the idea of Spring community. Java has more 3rd party libraries, but there are no one platform. The Spring present new framework ROO. At the first look it's pretty nice. Interesting how it's work for complex projects. Because for simple CRUD application it's wonderful. I think Java community need new technology for fast application creation. The maven help us to add dependency. But yet not exist flexible solution for assets.
