Retrieving information from website

Hi

I have a very basic question regd retrieving information from website using
a scripting language:

Basically I am working on the development of a database where a user enters
an address (street, city, state, zipcode). Based on the user input of the
address, I need to dynamically determine the latitude and longitude of that
address from the internet. One such website was :
http://stevemorse.org/jcal/latlon.php where we enter the street, city, state
and zipcode etc and the webpage returns the latitude and longitude.

I need to retrieve this information and update the database accordingly. My
question is: Should this retrieval be done using Perl or Php or thru any
other language ? What wd be the best way to incorporate this into my Java
application ? Any help/hints wd be appreciated ! Thanks

How often is this going to happen, and does the owner of the site allow
you to do repeated automatic requests?

IMO, if you are using Java, use Java. Otherwise you end up calling a
Perl/PHP program from Java, and processing the result of such a program.

Either PHP or Perl will do. With Perl you'll find the LWP::*
and WWW::Mechanize modules useful.

http://geocoder.us/ is another source. They take SOAP, and are
Perl-friendly (it's a one-liner using SOAP::Lite, once you have
instantiated the SOAP::Lite object). You need to pay them some money if
you are using it for commercail purposes. Personal use is free.

But I agree with John - if you're using Java use Java, which is
advertised as being wonderful for web apps. Of course the fine print in
the book I read said that if you were doing a "POST" you were on your own.
