How to get all AccountSubTypeEnums for a given AccountTypeEnum?

I am integrating Quickbooks Java API in my project. I am trying to get the AccountSubTypeEnums for a given AccountType. Is there an API to handle this?

There is no API for this.
However, Intuit does publish .XSDs for the schema, which contain all of the constants used, and are available here:

Getting information from a third party Wiki page

In the project I am working on I need to access information from the website explainxkcd.com which gives the explanation of specific xkcd comics. The information I am looking for would be the explanation of the comic as a string. Explainxkcd is a site that runs using mediawiki, software that forms a template for the "wiki" feel. Mediawiki has an api that allows you to extract information from their websites and I have gone to http://www.mediawiki.org/wiki/API:Main_page trying to figure out how to use their API for this particular wiki site but to no avail. It seems that you can replace the "index.php" in a URL with api.php to use the API but when I try this for http://explainxkcd.com/9/api.php it doesn't seem to work. I guess my URL is wrong but I don't see any information on how to find the specific URL to use for Explainxkcd.com
QUESTION:
How can I access information from a third party wikipedia page in a Java program? This can be through the mediawiki api or some other solution. If you know a good way to find the URL that can be used with mediawiki that would be preferred. Just looking for a nudge in the right direction here.
Thanks

Using the same method, s/index.php/api.php/, I get a different result: http://www.explainxkcd.com/wiki/api.php which seems to work. If a wiki is using pretty URLs (e.g. example.com/wiki/Main_Page), just click on edit, view source or history.
Yes, please use the API instead of screen-scraping. You can see a few existing Java libraries for that here.

How do I use Google Maps API in a Java code to fetch coordinates of specified location?

In a BI project I'm currently working on, we are in need of geo-coordinates for a list of locations. With the address location (such as "New York, US") as input, the output should be the coordinates as a latitude-longitude pair (like {40.71435, -74.00597}). The behaviour is similar to what is seen on this page.
A similar question earlier on SO points to using the Google Maps API in JavaScript to achieve this, but I'm looking for a Java solution -- some function of the form getCoordinates(location), because this is a small requirement in a larger Java program already in existence.
Any pointers on how I may use the Google Maps API (or any other maps API) in Java to achieve this would be of great help!

You can use the Google Geocoding HTTP API (see here).
To connect to it and get the responses you can use a Java URLConnection (tutorial is here) and parse the response using your favourite Json library (I personally use Jackson)

So you'd like a way to perform Google Maps API Geocoding via Java - here's one that might work for you. The response might not be in the exact same format you need but should be pretty workable:
http://code.google.com/p/geocoder-java/
You can see the final format returned in LatLng.java - just trace the code through starting from GeocodeResponse.java and you'll see the final format - the classes are pretty simple.

Getting Data from Internet in Java

I thought of making the following application for my college project in java. I know core java. I want to know what should i read "specifically" for this project as there is less time:
It will have an interface to put your query. This string would go as a query to internet search engines and with the help of search engine find the data (the first web page that we see (that is data for my application for this time. :) )).
I do not want to display the data. I just want the HTML file or the source code of the generated web page. Is it sounding like Common Getaway Interface? I do not know about this.
But i think it for the same purpose. If it is this. please guide me to know how to implement this.
Whatever please specify
Problem 1 : What should i read ? Any direct help at this point is not my intention. I want to implement it myself.
Problem 2 : Is connecting to internet requires some jnlp knowledge too.
for eg. as on google we search something it shows us the links of the websites. I can see the source code of this generated web page. I just want this page for my application to work on.
EDIT:
I do not want to rely on google only or any particular web server. I want to decide that by my application.
Please also refer to my problem 2.
As i discovered that we have Terms of Conditions for websites should i try to make my crawler. Would then my application not breaking the rules . Well its important for me.

Ashish,
Here what I would recommend.
Learn the basics of JSON from these links (Introduction ,lib download)
Then look at the Google Web Search JSON API here.
Learn how to GET the data from servers using HttpClient library here.
Now what you have to do is, fire a get request for the search, read the JSON response, parse the response using the JSON lib from #1 and you have the search results.
Most of the search engines (Bing etc) offer Jason/REST apis so you can do the same for other search engines.
Note: Jason APIs are normally used from JavaScritps on the UI side but since its very easy and quick to learn, I suggested you that. You can also explore (if time permits) the XML based APIs also.

URL url = new URL("http://fooooo.com");
in = new BufferedReader(new InputStreamReader(url.openStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
{
System.out.println(inputLine);
}
Should be enough to get you started .
And yes , do check if you are not violating the usage terms of a website . Search Engines dont really like you trying to access them via a program .
Many , Including Google , has APIs specifically designed for this purpose.

you can do everything you want using HTMLUnit. It´s like a web browser but for java. Check some examples at their website.

Read "Working with URL's" in the Java tutorial to get an idea what is behind the available libs like HTMLUnit, HttpClient, etc

I do not want to display the data. I just want the HTML file or the source code of the generated web page.
You probably dont need the HTML either. Google provide its search results as a web service using this API. Similarly for other search engine GIYF. You get the search results as XML, which is far more easier for you to parse. Plus the XML wont have any unwanted data like ads.

Parse JSON response from Google Maps page

I'm trying to find the best way of parsing the response from a "normal" (i.e. not using the API) Google Maps page in my java code.
Reason: I want to submit a query string requesting a listing (be it hotels, restaurants etc.) and then parse the JSON that comes back. I had looked into using the Google Maps API, but it doesn't seem to cover what I want to do, as this type of URL:
http://maps.google.de/maps/geo?q=address&output=xml&oe=utf8&sensor=false&key=...
is OK but this isn't:
http://maps.google.de/maps/geo?q=address+hotels&output=xml&oe=utf8&sensor=false&key=...
(due to the "+hotels" term). So I think the only option is to use a google maps response e.g.
http://maps.google.de/maps?q=address+hotels
and parse the JSON information that is included at the end. Does anyone have some hints as to how best accomplish this?

You should first make absolutely sure that the API doesn't support what you need. Checking the docs and maybe even reaching a real Googler might pay off. It strikes me as odd that their API wouldn't support something as simple as adding in another term.
If you're forced to do it the "hard way", there are two main steps:
1) Find and learn a JSON parsing library for Java. I can recommend Jackson -- fast, sturdy, and just released a version 1.0.0.
2) Teach your code to understand the spec the Google uses in their response. This is by far the most challenging part. My apologies, but I know nothing about Google's spec in this area. If you can find official docs, that's best. Or find unofficial docs published by someone else who had to do similar work. Otherwise, you may have to "reverse engineer".

Re. the google api docs: it does seem that what you're trying to do goes against the intention of Google to make their product (= a map) available to you, the developer, for your custom enhancement (by adding business outlet information or whatever). There's plenty of stuff on the Google maps API site describing this. But to parse their data (coming out of their database) and to display it independently of their product would seem to be rather different: section 10.12 of the terms explicitly cover this:
...code.google.com/intl/de/apis/maps/terms.html
However, there are apps out there (the "Around Me" iPhone app, for example) that seem to do just that: there might be a special arrangement between Google and Apple in that regard.
EDIT: alternatively you could look at this problem another way and use the Google Base API feed, since this allows you to build query strings specifying resource, distance, location etc. - i.e. it returns the data you require without using the Maps API (which you don't need anyway, given your description).
