I am using class.forname() in several classes to load other classes so that my application can be configured without changing the exsisting code . I am not very clear about the issues which can come across using class loaders . I tested in my localhost where all classes reside in one container, it works . But in production and tdl ,the environment is clustered and app tier and web tier are seperated so could there be issues with class.forname() or dynamically loading classes which I donot see in my development environment but can arise in production because of clustering or seperation of web tier and app tier.
