basic lesson 14:Protecting your website with a login page

Some sites require that all users log-in using a username and password, before being able to visit any page.
This can be done using JSP sessions or servlets, and in fact this was a common technique for a while.  But starting with a new release of Servlets specifications (2.2) from Sun, this feature is now very simple to implement.

It is no longer necessary to use JSP techniques to provide login/password protection, but it is still a very common requirement of web-sites, therefore a brief overview is provided here.

To password-protect your site, you just need to design a login page.  This page can be as simple or complicated as you need it to be.  It must contain a <FORM> tag, with the METHOD set to POST and the ACTION set to "j_security_check".

<FORM METHOD=POST ACTION=j_security_check>

2012 PHENOMENON

The 2012 phenomenon comprises a range of eschatological beliefs according to which cataclysmic or transformative events will occur on 21 December 2012. This date is regarded as the end-date of a 5,125-year-long cycle in the Mesoamerican Long Count calendar. Various astronomical alignments and numerological formulae have been proposed as pertaining to this date, though none have been accepted by mainstream scholarship.

A New Age interpretation of this transition is that this date marks the start of time in which Earth and its inhabitants may undergo a positive physical or spiritual transformation, and that 2012 may mark the beginning of a new era. Others suggest that the 2012 date marks the end of the world or a similar catastrophe. Scenarios suggested for the end of the world include the arrival of the next solar maximum, an interaction between Earth and the black hole at the center of the galaxy, or Earth's collision with a planet called "Nibiru".

Scholars from various disciplines have dismissed the idea of such cataclysmic events occurring in 2012. Professional Mayanist scholars state that predictions of impending doom are not found in any of the extant classic Maya accounts, and that the idea that the Long Count calendar "ends" in 2012 misrepresents Maya history and culture. Astronomers and other scientists have rejected the proposals as pseudoscience, stating that they conflict with simple astronomical observations and amount to "a distraction from more important science concerns, such as global warming and loss of biological diversity"

• 50.5% of the 1,50,000 (75,750 candidates) will be taken from the top rankers of the Common Merit List (CML) of JEE (Main). 27% (40,500), 15% (22,500) and 7.5% (11,250) candidates will be taken from the top rankers of the category rank lists of OBC-NCL, SC and ST, respectively. The candidates figuring in the category rank lists will be those who do not figure in the 75,750 candidates chosen from the CML.
• 3% of the candidates selected within each category will be those belonging to PwD (Persons with Disability) sub-category, who figure in the respective rank lists of JEE (Main).
• Only the candidate’s aggregate marks in JEE (Main) will be considered and no tie-break mechanism will be implemented at this stage. This will make the list of candidates eligible to appear in JEE (Advanced)-2013 slightly more than 1,50,000 due to bunching of candidates with the same aggregate marks at the bottom of each category.
