Solved Whats this error mean (i'm being nooby?)

Solved

 

HelloThereMain.java:66 This means that there is something wrong on line 66 in the HelloThereMain class
It is a NullPointerException, that means, that you didn't defined something correctly, the server sees it as null, nothing

 

If you need more help, you'll need to show us some code. Please include the line numbers, so we can see where the error is.

 

The error was moved to line 71 due to puting line numbers

You should split your code into several methods, each of them doing a specific thing, with a relevant name. That will clarify it a lot. I think your problem here, if the error is on the line I think, is that you don't have a list under the key "messages" in your config.

 

Like I said I was just trying to update it, meaning I didn't write most of it, I will try your suggestion

 

If you update someone's code, first understand it (all of it), then re-write it to make it your own (and maybe improve it in the process).

 

Will do Nitnelave, I just recently started working on java in general, guess it's time to learn hashmaps.
Good thing it's spring break next week XD

Ok, so I decided to re-write it, I just need to know, how do I put text into a text file, could I use somthing like this http://www.javapractices.com/topic/TopicAction.do?Id=42 or do I need to do somthing entirely diffrent?

Yes, it seems good, but don't use the java 7 version, it is recommended to be able to compile on java 6, or even 5.
