I wrote a pair of Applets to compute sales tax.  I did some looking at
web hit stats and discovered the Canadian Tax calculator  is my most
popular piece of software.   It would be nice if it could
automatically default configure itself to the province/state of the

What is the best IDE to use when developing Java applications?

I want a website that is a CMS, has usernames, password.  The "normal"
security system stuff.  I know there are a multitude, just assume that
people create accounts and the credentials are stored in a MySQL
database.

I have a web page http://somehost/somewhere.html which contains an
applet (the applet jar is now signed).
<APPLET CODE=myApplet24.class ARCHIVE=myApplet24.jar WIDTH=768
HEIGHT=850></APPLET>

I was trying to figure out how to connect an applet to a mysql
database.  I only found very old articles on it.  It seems no one does
this.  So, now I am stuck.  I want to write a game in an applet that
utilizes a database.  I don't want to use Flash and php, which I keep

When the number of elements gets above around 2700 the Arrays.sort
inside the Collections.sort throws an exception:
java.lang.ArrayIndexOutOfBoundsException
Any ideas?

If you are creating an application that is going to be run in an

Is there any way I can customize a JScrollPane and instead of one
horizontal JScrollPane it would show two? Can you point me somewhere?
Thank you.

How do I find the number of rows in a multi dimensional array? The
number of columns can quite easily be found with A[0].length, but Java
unlike Matlab does not allow an expression like A[][0].length . I
suppose that there is a way around it.

I have a crawler program,  it fetches html on the internet and a
parser will parse the page.
Because of slow networks, I use many robots to crawl the pages and
one parser.

I have written quite a bit of code that loads an entire file into RAM
then does indexOf, substring, regexes etc, working on the giant
String, often creating a new giant String and writing it out.
I wondered if anyone had developed some sort of package to allow such
