Hello, welcome to this lecture.
In this lecture, we will study about Barometer's as a source of data access for subjects previously
used in Barometer's Novant study barometer's.
These are typically farm fields which are submitted from a GSB file or an e-mail file be used initially.
And finally, Finnerman.
But in next door testimony in the logging application we use in next hour to post posts that confuse
the user name and password.
So we will see that later.
But these are typically from fields posted by a GSB orange.
You can only read that you cannot write.
You can really read them using request get better meta Funen.
And these are of string type the type of these parameters on this thing.
OK, so now let us see in eclipse how it looks.
The open eclipse.
Close this.
Businessman, Waterlogging Servlet.
Now in Logan Servlet.
We got a new post because this was the post form so that we posted a form from a Turkish deamon and.
What we did was.
You're going to get better with that username requestor, get better password.
These were the farm fields, username and password and used get barometer to get the better meter and
this type thing.
So the type is always getting you get used to request object to get better meter and this is how you
get a better meter.
You can set up an ATM.
You can write about a meter.
You can read about a meter.
So you read the barometer and you use the name username in the name has been given as user names.
So we use exactly that as a starting point to get better meter.
So we use fundamentally what the point is that we use to get better, meaning the method of the request
to get a better return.
So this is the essence of parameters.
In the next lecture, we will study attributes.
So see you in the next lecture.
