The tutorials are great. This is my first tutorial series on the channel. Navin Sir is amazing at Java and on the concepts. Recommended to all Java lovers or better be learners.

Great tutorial, We enjoyed it sir. God bless You

hello sir, since we're modifying the url from res.sendRedirect("sq") to res.sendRedirect("sq?k="+k), how the compiler is looking this new url-pattern in web.xml? since we've defined url-parttern for only "sq" not "sq?k=".

[franciscasimirs]

Thanks a lot. It really helped me to prepare for my practical examination

[pavanchandaluri]

Hi Navin, thanks for your content. If i'm using doPost method instead of doGet it does not work. Could you may be shed some light on that

[wpatyune]

These two looks like similar purpose. Are these function doing the same purpose or depending on a certain occasion?

[harshithas]

In web.xml we have mentioned sq in servlet-mapping how can it map the same after using sq?k= in send redirect.

[mohanas]

Hi Navin, I believe there is one more concept called 'Hidden Form Field' in session management technique. we can send data from one servlet to another with this hidden field.

Hi Navin, Firstly I would like to thank you for this wonderfull series.I have one doubt i.e. sendRequest can be use only with get method ?

[bhavaniyallavula]

Great teaching sir. Thanks for ur videos.
I have a small doubt in this concept. Please clarify sir.
In the URL Rewriting, we actually changed the url pattern the client should call the sq servlet, but that same url pattern is not configured in web.xml.
Then, how do the server know to call the same sq servlet?
Thanks in advance.

[TruongNguyen-lrjf]

So do we should use sendRedirect or Dispatcher ?

[Saiyam]

can anyone help me ... after using setattribute in AddServlet i got an error coz it is saying that k is not an int type..convert into object..but after making it as object i get an error in ...int k = i + j;..
how to resolve it?

[pentainamerica]

dont we need to modify xml file once we change the argument in SendRedirect?

[shivanshuvyas]

What if we want to send the data using post method in sendredirect(), would we able to do so?

[patyue]

But why response dispatcher is used instead of this redirect method? Which one is common to use? Or in what circumstances we should use either one? Any practical example(s)? Thanks.

[spyrostomaras]

very helpful video congratulations grom greece man

[akarshgupta]

when we change url from sq to "sq?k=", doesn't the web.xml file plays a role in executing the url mapped in servlet mapping

[tekina]

what if it was a doPost in servlet1? then using URL rewrite wouldn't work right?

[prabhabaskar]

Doubt :
res.sendRedirect("sq"); & res.sendRedirect("sq?k=");
"sq" & "sq?k=" is different right ??
While configuring at web.xml
<url-pattern > /sq </url-pattern>

The actual pattern mentioned at url pattern is /sq right ??
Then how it correctly run instead showing err ??

[blagovestkabov]

But what happens when we use doPost method and we can not see the values in the URL?
