You can use the existing type that has no no-arg constructor by using a builder inside a factory method. No weird reflection needed - just a builder that knows how to construct the target object. Since the builder is a *new* type, your comment that it doesn't have this or that is ridiculous. You create the builder with a no-arg constructor and build what you need, returning an instance of the target type to the factory method. How about you speak to that suggestion, hm? -- Lew Honi soit qui mal y pense. http://upload.wikimedia.org/wikipedia/commons/c/cf/Friz.jpg
