Changing color scheme and font settings in gvim

I like using vim for quickly loading a file for view/edit etc on my windows m/c. 
At work, with the monitors being 21" in size.. I wanted vim to open up on a larger frame, and also wanted to have some tweaks incorporated (font, color scheme, tab width, etc). I thought I'd simply have to edit my .vimrc from my home directory and voila.. everything should work. Well.. not quite. It works fine for my command line vi invocation from cygwin, but not when I open up from vim. After googling a bit, found few suggestions which satisfied my needs. All you have to do is to edit the _vimrc file which is located in you vim installation folder. For instance, C:\Program Files\Vim 
You can either edit it directly, or open up vim editor and goto Edit -> Startup Settings. Once opened, you can add the settings to the file. In my case, I added the following: 

set tabstop=4
set number
set lines=50
set columns=120

If you need to change the color scheme, chose the color scheme that you liked, and add the following to the _vimrc file:

:color morning

For font settings, choose the font that you like, then type 
:set guifont?
This will display the current font setting information. Note that down and set it to guifont in _vimrc.
Here's mine:

if has ('gui_running') 
 set guifont=Bitstream_Vera_Sans_Mono:h10:cANSI
endif

Happy vimming!! And thanks for those folks who put out this nice little tidbit about vim settings.. 

JSON Hiccups

This is my first entry into the JSON world and everything looked pretty straight-forward from the outset.
When the time came to dig in and use JSON and map it back to POJO's, issues started sprouting, but nothing too daunting or complicated.

Issue 1: I had to call a RESTful webservice which responds with application/json type. I dont have the JSON schema available and the JSON object is quite large (requiring quite a few classes and fields). Now I needed to generate the java classes, but couldnt figure out an easy way (like how you would generate classes using XML schema). I could lookup the json string and then create the Java classes manually, which is what I did for the simpler json responses..but for the larger responses, it didnt seem to be a smart way to go about. After some googling, found this wonderful link http://jsongen.byingtondesign.com/ which generates the java files for you if you could provide the url for the json request! What a time-saver?

Issue 2:  This time, I was getting a json string which didnt follow the standard syntax. All the property names were capitalized and some properties were just named '$'. While reading about the json mapping, I understood that badgerfish, when creating json string from xml schema generates '$' as the property name to represent the text between the xml element. ex:
XML: <customer>Arnold</customer> is represented as
JSON: {"$": "Arnold"}
But due to the capitalized property names, when I tried to use ObjectMapper.readValue(json, Class)...it fails due to the fact that its looking for a property with lowercase name. To overcome that, I then had to use @JsonProperty annotation on each property in java file to match the property name in json and everything went smooth after that.  

Issue 3: Some of the generated java files didnt include all the property names that were found in the json string. So when I tried to map the values from json into java objects, it failed with an org.codehaus.jackson.map.exc.UnrecognizedPropertyException. If you need that property, you'd have to add that in your generated java file. But assuming you dont need that property and you dont want to keep adding those fields which is not needed by your app, the simplest way is to disable the FAIL_ON_UNKNOWN_PROPERTIES feature in Jackson's deserialization config by calling:

ObjectMapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);
