Something regular would be best - IMO. I think I favour a Smalltalk-style factory method: ClassName c = ClassName.new(); // construct... class ClassName { ClassName new() { ... } // constructor... } This is more regular than having dedicated constructor syntax - I would think. I doesn't deal with the class name, though - unless you allow: "static new()".

The multiple-inheritance thing isn't much of a bugaboo... it's not used all that much anyhow. The big problems are that (1) The libraries are very different between java and c++, and learning to "think" in terms of the STL takes time (2) The garbage collector in java lets you get sloppy with memory management...no such luck in c++ At a rough guess, it'd take you about 6 months, working with c++ every day, to become what I'd consider "fluent" in c++ (i.e., when confronted with a design problem, be able to sketch out the system design and bang out the code without having to consult the manual every fifteen minutes). If the job is mostly maintenance programming, then that's a horse of a different color -- you should be able to do useful work almost immediately (i.e., you can figure out c++ while you're figuring out the existing system and the existing set of development tools). ============================================================================== TOPIC: Sockets http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/edecab678cd31cd6 ============================================================================== == 1 of 1 == Date: Tues, Dec 7 2004 3:35 pm From: Michael Borgwardt FunkyKarma wrote: >>>The content doesn't matter. >> >>Yes, it does.

Sure, but what are you going to *do* with that knowledge? How do you get it to the receiving end?

There probably are, but I can't point you to specific ones.

The "standard" license may not include any distribution rights at all, in which case users would have to obtain their own licenses. Or you might have rights to distribute it freely. You might be able to come to an agreement with the licensor of the 3rd-party jar to act as an agent for them to license their jar to your clients and distribute it. Their are boundless possibilities. The only sure answer is to read the license and discuss its terms with the licensor. It may be in your best interest to involve an attorney. I am not one.

In the end, the answer is that you should do what the library author/vendor requires you to do. If there's text in the license requiring you to obfuscate the code before distributing it, then do so. Otherwise, it's not worth your effort to obfuscate a third-party library. Although you seem to consider obfuscation a key part of deployment of anything, most people don't share that extreme viewpoint. I can see why some library providers may not want you to do so. In my personal judgement (which is not an informed legal opinion, and encompasses more than legal requirements), your unprovoked obfuscation of someone else's code is more likely to cause problems than solve them. -- www.designacourse.com The Easiest Way To Train Anyone...

Maybe not. Googling returns a heap of different discussions about the subject, and not a very clear conclusion. So, I will try to re-state the question: Does a method create a stack frame for ALL local var's at the beginning, or does it increment/decrement a stack pointer along the way, thus re-using stack space?

Paskin" Hi, I am using the validator framework within Struts. However, I noticed if there is a session timeout the validator just throws a NullPointerException. I am using the standard validators, required, double, etc. Is there a way to do something if a timeout occurs?

At the moment I'm trying to develop a renderer with its own iteration, as suggested in paragraph 9.2.8 of the JSF 1.1 specs (I wouldn't really like to use dataTable), so that I can have the same functionalities of the JSTL forEach. Since it's taking some time, I thought that it might be better to get it somewhere. Unfortunately at the moment not only I can't find a renderer like that, but I can't find even a repository of JSF components or renderers. Does anyone know one?

And what happens if you refuse? That, I think, is the real test.
