Nicolas Frankel has a nice article over at dzoneon what you can do with proxies in Java. As he reminds us in his introduction to this article there is real power inherent in Java if you are familiar with the way that proxies work. He covers shared Java proxies as well as CGLib proxies, the latter of which do away with a lot of the limitations enforced upon programmers by pure Java proxies e.g. you don’t have to implement interfaces and you also can extend classes with it. This is a well-written, erudite article that is a outstanding introduction to Java proxies.
