In fact, I'm doing this in Java, it's a Maven project and hosted as a web service on GlassFish. The service returns the data in json format. The problem is when the values are null, I have to serialize them as "" or "null". I want to return as just null. However, I still can't find a way.

You really need to have a good understanding of the use of classes and their methods and properties for such a project. However, the first thing you need to do is work on the actual design of your project. The data store, what information you need to keep, and how you will access it. The inputs, how customers will request reservations. The outputs, how information will be displayed etc. All of that needs to be designed before you can start writing any code.

I just ran an internet search for "eclipse java profiler". The results are confusing. I was expecting to find a list of tools or at least a simple tutorial on how to use a free one, but haven't seen anything of the such.
I find it hard to believe that an OSS profiler doesn't exist. Can someone point me to a tutorial on how to use one? Preferably with eclipse integration.
