America always talk about peace.. and say that they are peace makers in the world. And say that the Muslims are the terrorist.
And the fight to maintain the peace in the world
Here are some of the great peace milestones that America laid in the heart of the innocent people.
And who is there to speak against it......
Is it a war against TRRORISM or war against PEACE

Websphere
when i heard about websphere i was confused a lot about what does it really mean. any how found out some fact about it which i like to share with you.
Websphere is a brand name of IBM which consist of a family of products. But in common Websphere Application Server (WAS) (- it is an application server) is simply ment by websphere.
It consist of 3 components:
1. Foundation tools
2. Business Portal
3.Business integration
If u really like to learn about it ....
http://books.google.lk/books?hl=en&id=H4Ilf0ZiJZ0C&dq=java+programming+on+ibm+websphere&printsec=frontcover&source=web&ots=b5RRDfMbS7&sig=9IIEmEdoIrC7SmeurDC-hXYZ4Hk#PPA39,M1
Because just now I'm also refering to it :D
