Just curious to see what people have done out there in conerns to difficult projects.  For one of my computer science classes the professor made us write an assembler and emulator using JAVA with a subset of opcodes.  That was one difficult project!

JCreator definitly helped make that project 100x easier.

I think the hardest thing for me is the project I'm currently working on... It's a chatbox, which I love to make... The idea is to use only custom components, which have to work under Java 1.1... In some cases, it's pretty difficult :-)

Also the Server will be pretty difficult to make: It has to 200% perfect :-)

A distributed fileserver.  I didn't sleep for weeks.

I'm doing something like that now for work but in C#... it is keeping me extremely busy.

A webserver (which totally lacks support for any standard at all) that serves HTML pages .
My first experience with socket programming :)

Im planning on making my own webserver... Is it difficult? And what resources did you use (API, examples etc...)? :-)

It is not very hard, well.. if you prepare it well enough that is ;)
I created my webserver from reverse engineering the input i got from apache in putty, which is not a good/easy way to create your own server.

I used the following imports:
import java.net.*;
import java.io.*;

.net (of course) for the Sockets, you will definately need this one.. hint: ServerSocket
.io for reading the files that are being requested by the client

I could send you the source code for review if you like (pm me an adress or something and I'll mail it to you asap)

[MajinZ]

Off course it was pretty obvious that I would have to use a ServerSocket, and some I/O-streams... That shouldn't be a problem...

Mmm... I can't send you a PM :-O Stupid forum :-P Anyhow, my e-mail address is on my profile :-)

Just to make it a little easier: hans_roeder@hotmail.com

I'm really curious about the code right now :-)

Sent :)

the code is butt-ugly at some parts, but it works as intended.
It's just that the intention was to serve a page and *not* crash the server doing it, keep that in mind while you are reading the code ;)

[MajinZ]

Great :-D

The code looks fine, so I think I won't have any problems reading and understanding it...

Thank you very much :-)

[E-E-R]

You're welcome, if something isn't clear you can always email me (dutch or english or german doesn't matter, french is acceptable, no other languages :P) and I will try to explain it in more detail (since I did not comment anything that shouldn't be really that hard).

[MajinZ]

dutch or english or german doesn't matter, french is acceptable, no other languages :P

Hehehe, I think that's pretty funny :-P

Dutch would be best, since we're both uh... Dutch :-P I don't speak german (though I am half german :-$)... And french... Blegh, hate it :-P

I don't think I'll be asking you questions, but thanks anyway :-)

To bad you write the code in a syntax I don't really like... Now I first have to adjust everything :-P But I'll survive it I guess :-)

Thanks again, really appreciate it :-D

[bradleysmith]

Probably a sheet metal auto-unfolder.
Or a CNC plasma programmer.

Both seemed pretty tricky at the time.

Think you could send that web server to me as well?  wayneclarke "at" comcast "dot" net

Now everyone knows my true name O_o

[MajinZ]

There's nothing wrong with your name :-)

I'll send that later tonight...

(not my hardest project, just a response):
I wrote a simple webserver that essentially makes a specific folder available over HTTP. It was most just to practice my Java and networking stuff, but it works. It doesn't support all of the HTTP headers though... I don't think it supports enough to comply to the HTTP standards. It works fine for me though.

Personally I routinely find that what makes a project hard is not the "big requirements" but the "little requirements". One of my very first Java apps was a web site link-checker, something that ran all over a web site checking for broken links. While I'm sure my code sucked because I was new to Java, I was amazed at how easy it was. I thought it was going to be tough to figure out how to connect to a web site, download a page, extract links from it, etc. But then another early Java app I had to redefine the behavior of the Page-Up/Page-Down on a JTable. Sounded simple enough. It took me forever to figure out how to do that in Java 1.2, and then when Java 1.4 came along it broke my solution and I had to do it all over again. (At least the Java 1.4 way was fairly clean. Which reminds me: I still don't understand why an InputMap and an ActionMap are two separate things. Why not just have one entity that directly maps key strokes to actions? Why do I need the middle step? )

The hardest program I've done (and actually I'm still working on it) is a thorough and sophisticated scheduler/datebook/organizer program that is specially focused on user-friendliness and aesthetic interface design... I'm doing this without using a GUI builder or any other code generation tools. I started it last October, and just do it in my free time... I might have it ready this summer or fall if I'm lucky... :-)

i'm a beginner, and the hardest program i ever made is for my BTS (french diploma), it consists to interact and drive a 2-axis hardware, via internet or ip, and take informations by the camera (this system is called "heliostat", for the DGA, this is a specific energy source, "four solaire"). I had difficulties for programming I/O card.
I make another program, which lists movies and games, in a list, ... it's more graphical and it contains more functions. (i included server/client, for network support)

CheezItMan and Sahisoft, i 'm interested by your fileserver and notebook/organizer, if you would give it to me, I really thank you.
