    Nataly

    Nataly

    A framework that translate name-based pointcut to analysis-based ones

    Nataly, which can translate name-based pointcuts into analysis-based pointcuts automatically. Analysis-based pointcuts, can specify join points through static program analysis. But another problem is that there are few approaches can generate analysis-based pointcuts. We implement Nataly to tackle these two problems with a novel pattern, which is generated by static analysis.

    Pop Framework

    Pop Framework

    Use Java bean as model of web page, reference beans in hyperlinks

    Pop Framework (or Pop), http://www.popframework.net, is a bean-based MVC framework for Java/J2EE web applications. Pop implements IoC, Dependency Injection, and AOP. Pop provides annotations for users to define and reference a bean. Pop can help users to customize a bean, a scope, a factory and a reference in object-oriented way. Pop treats a bean as the model of a web page (JSP or servlet), the webpage itself is a view of the bean. The model provides the data for the view, the view is responsible for rendering the data. The Pop itself acts as the general-purposed controller for all views and models. The beans defined in server-side can be referenced by hyperlinks in client-side directly. Views and Models are therefore loosely coupled in Pop. A model can have multiple views for different devices and different locales. Each view and each model can be maintained and optimized independently and in parallel.
