The latest german Eclipse-Magazin contains an article that I wrote together with Peter Friese (from Gentleware) and Heiko Seeberger (from Metafinanz) about using AOP for Eclipse RCP applications. The article describes how load-time aspect weaving can be used for real-world OSGi-based applications. Within the article we describe how security-related issues can be implemented using AOP and how those aspects can be woven into an RCP app using AJEER or the Equinox Aspects load-time weaving support for OSGi. The complete article can be found in the publications section.
