Neopets Programming with Java

[Sean]

This is just a quick write up with some .java files to help you get started. Joe requested this from me a while ago and I've been slacking on putting it up.

First things first, a few files that may be beneficial to you:

Connection.java

This is the 'wrapper' or what you would use to connect to neopets and interact.
It's simple to use. Once you create a new instance its just neo.get("") and neo.post("", new String[][] { {}, {} });
If you need to set a referer, you can do that manually. Otherwise, the referer is set to the last page. There are a few modifications in this that I added such as proxy support, support for the potential botcheck, etc.

Apart from this, what joe really wanted was the gui creator for eclipse that I use.

Currently, I am using google's WindowBuilder Pro. It's a simple eclipse add-on that allows for quick gui creation. There are some bugs that i've found with it but nothing major and it should work for whatever you want to make.

That's all I'm going to post for now but if you have any other questions then feel free to ask.
