The picture was taken on the Final Days at the battlefield in Mullaitivu, Northern Province of SRI LANKA when the so called "Invincible " terrorists named as LTTE or Liberation Tigers of Tamil Eelam, were completely decimated by the Sri Lanka Armed services. The long drawn out war of 30 years is over and PEACE has dawned in Sri Lanka once again. The picture epitomises the gruesome atmosphere of a fierce battle, and the natural humanitarian action of a Sri Lanka Army soldier saving a Tamil toddler and taking him to safety.The toddler shows full confidence in the soldier.

In past few days, I had to work on implementing a functionality for sending an HTTP request to another url and upload a file with that HTTP request and then get the response for the HTTP request from a Java servlet. This is the code I finally created for achieving my task. It does,

1. Connect to another given URL
2. Upload given string as a file to the above url
3. Then read the response for the above HTTP request.

Nowadays, many of us use TinyURL s instead of using long urls for the ease of use. Think that a site you visited has a tiny url like http://tinyurl.com/c8yvgr. We can not directly say whether this tiny url links to a good site or a porn site or a other malicious site by looking at given tiny url . But now you can preview the actual URL before visiting the target site using a feature provided by http://tinyurl.com.

In these days I'm involved with a project using a PostgreSQL database. This is the first time I'm working with PGSQL, So I could learn some new features in PGSQL. One of the requirement I needed while coding is to find an easy way to get the auto generated primary key value when inserting a data record to the PGSQL database. I could find several ways to do that and one of method I found was really easy way. Those methods I found are described in this post.

First Method:

public int insertData( String name, String address, String tp_no)
{

int insertedKey = 0;

ReCaptcha is a widely use Captcha generation web service which is owned by Google. Yesterday I had the opportunity to use ReCaptcha for one of my project. But there was a problem. Since ReCaptcha is generated to a certain style, width and height using a webservice request, it was hard to put it into the design of the form which I was trying to integrate ReCaptcha.
But finally I could solve the problem using some tricks. This is how I did it.
