Thanks for your reply.
As a
java developer i just want to improve my skill in Java.
I didn't describe my whole problem before because i just want to start with small requirement.
1. Identify the restricted key words from URL in browser.
2. Show "Warning message" and restrict particular site.
3. Send email to admin for trying to access for that particular restricted page.
4. Send email to admin for trying to disable or uninstall application.
Now could you tell me an idea how to go about this?, if already exist please refer me i will go throw that.
