[@Judosaper]

Thank you for excellent video about filter. Even with my bad listening English I understood how to use filter. But before when I read about it in my native language I didnt get how to use It. Thanks a lot friend!!!

[@AnshumanSharma-m1z]

The best playlist for understanding Servlet and JSP.

[@elitesharma817]

Thanks to you sir, I don't need to spend my money on anything just my wifi and you're there to teach us well. BTW I created 2 filters with typing each line on my own. And they worked very well. I'm very much grateful to these tutorials sir, thanks

[@GokulSankar-jz5oo]

Really awesome.... very nice and simple..... i spent 5hrs in google for this filter concept 😢

[@rajki007]

Can you do video on how to implement to call multiple filters in specific order? BTW Nice Video, Thanks

[@milansharma9810]

done here is my solution- HttpServletRequest req = (HttpServletRequest) request; String aname = (request.getParameter("aname")); PrintWriter out = response.getWriter(); System.out.println("milan"); if(aname.length()>3) chain.doFilter(request, response); else out.print("invalid String");

[@saubhagyasharma4528]

This entire 35-videos playlist for JSP has been very useful. Thank you. BTW, why do you address everyone as "aliens"?:D

[@javito1992]

i was going to ask the same question xd

[@tejasnareshsuvarna7948]

He uses the word aliens because programmers are different people. They always do things differently unlike normal people and keep searching for answers. That's why he addresses us aliens.

[@shaikkarimulla6318]

Done with assignment sir. Thank you very much

[@dollykaur75]

Thank you so much sir for great explanation of concepts

[@simbol5638]

Great lecture sir. here is my solution. if(nam.length()>=3) { out.print("This is Your filter name: " + " " + nam+" "); chain.doFilter(request, response); } else { out.print("Invalid Input");

[@fuadshirinov2116]

@Telusko One Quetion. Could you explain how to implement this technique to use GZIP so we can uptimize the website using Java EE? Thank you so much for your tutorials i subscribe

[@CreativityWithDeep]

I did it sir... thankyou sir for sharing your knowladge for us...

[@abhishekraj4386]

Hi Sir, I am unable make chain of filter, could you please explain how to that. Thanks for the Tutorial.

[@SriVinayA]

I have done the assignment sir.

[@parthchaturvedi2333]

Sir , you typecast the request object to HttpServletRequest Obj but used the Servlet request again and It worked

[@parthchaturvedi2333]

In the filter

[@drakshayanibakka11]

It's worked but I have a question I have created two filters for id and string check but I just want to know which filter will be called first either id filter or string filter and how these filter chaining happens .Please make a video on filter chaining .Thank you sir

[@somsuryananda]

Really a good explanation of the Filter theory. Very good work Navin. Love your videos. Also wanted to know your opinion on the taking the exam OCEJWCD.

[@suryakumars3117]

Is it Really Important to Typecast ServletRequest to HttpServletRequest?

[@deepakadik1210]

Nice

[@alexisbrunet2707]

That's really helpful, thanks a lot

[@abaisyet]

[@abhaydeshpande3239]

New Filter Implementation done!

[@morigene]

Nice explanation

[@maheshsahoo9980]

it is awesome ... sir please do next video ....

[@kidsfun381]

thank you so much sir for making this course

[@MisterXS75]

please make a video where you explain more about filter chains how do you say which order the filters are supposed to be called? does the filter need to be called exactly the same way as the servlet we want to filter? if i have more than one filter will they have all the same name ? thank you very much for you classes i'm learning a lot thank to you

[@njadnissi7455]

Hi Telusko, I wanna ask : between using JavaScript and Using Filter to check wether data in the form are right before to sending to a servlet, which one of the choices is the best.???

[@crickopedia8343]

thank you so much sir for this wonderful playlist of servlets and jsp Sir i want some more stuff like how we can sort and filter products etc. Like in flipkart amazon

[@Nelipson]

Done homework easily

[@sunilreddy814]

Sir, this was really helpful; my question is how to redirect to an error page or create session and print the error on the same form page. Thank you.

[@SaurabhKumar-bv9gs]

Yes, I have done your assignment sir. But one think I have found is that in order to chain the filters, I have to define all of them in web.xml even if I have used @webFilter annotation. Can you tell me if there is a way to order the filters using the annotation itself. Thanks

[@aszaw5342]

you can use that with using alphabetical name of your filter as > AFilter applies before BFilter .. and so on without define all of them in web.xml

[@huasheng1891]

Mr. Telusko: I think It should be: int aid=Integer.parseInt(req.getParameter("aid"));

[@floraaraya9984]

I have the same thought. It should use the req not the request.

[@shoaibnusrat9817]

Sir please can you make more vidoes on this topic so that we can advance these languages

[@ektachavan5221]

Hello sir it was a nice tutorial... I am facing issue as I have created two different filters for two different url one is global and other one is specific to single url.. This is not allowing my application to load. Please let me know what can be done under such scenario

[@seeteshguptasg4300]

sir, how can we interconnecting multiple filters..please make it video on that.. and how can we configure filters on web.xml file..please explain us..

[@anguilavigilante9454]

Hi! Please how can you use Filter to prevent Hotlinking from our images so tha if some body else copy our link and use one img Tag to display images in his web this image should not appear. Thank you very much for your Job

[@surajtopal9940]

thank you sir

[@abhijitthorat9296]

What is the difference between Filter and Spring Interceptors? When to use what?

[@moocheeseee]

what if we want to implement the invalid message somewhere in the login page?

[@sachintr8086]

how to make the filter to the specific servlet

[@vigneshwaran5803]

It's really nice sir. But how to configure this filter in web.xml file?

[@mohawberel]

You are awesome

[@yashtibrewal4259]

can I define the sequence on my own? also how do I make this filter for 2 different servlets, do I add one more @WebService? or copy paste the code?

[@yuvrajbrother3017]

THANK YOU SIR I AM A STUDENT OF I NEURON

[@anuragsinghnegi2165]

sir, ho do we chain multiple filters? like checking ID in 1 filter and checking name in another filter. How to chain them?

[@drakshayanibakka11]

yes I too have these doubt

[@Soumen110]

if(aname.length()>=3) chain.doFilter(request,response); else out.println("Invalid text input")

[@larhchimismail3399]

we can use regular expressions instead

[@compartelo007]

Thanks

[@TechHacksmohitsharma]

Done Name Filter!!

[@tharsantharsan416]

.. sir how to differentiate Get , Post request in filter

[@sagarmeena0210]

nice

[@rohitdhingra7186]

Can we maintain Order of filters in Java Configurations without using web.xml

[@KhuntRaju]

Awesome...

[@akashchhetri4827]

My name is A. 😂 Sir u r amazing

[@santhoshkumar.l7886]

sir i understood but please explain little bit clearly noting but with lot more 2 to 3 examples.

[@amanwithoutanyaim9503]

Done

[@gehnasrisravan]

Before login with username and password i have to some other default authentication with filter only in this case how can we do that stuff..??

[@umeshmanikdurge7885]

how to apply one filter on multiple servlets??

[@ambeshtiwari9977]

if(aname.length()>1) { chain.doFilter(request,response); }

[@alexthurston9940]

He says, "At least, more than 3 letters" - so >3 instead of >1

[@buradanaveen5008]

thank u much n u r the best but can u upload the code without annotation using web.xml file

[@JujareVinayak]

web.xml is complex than annotations

[@mickykumar7573]

Sir how to display all images from folder to jsp page sir please make on it.

[@highongameshog2439]

hey how can we maintain order of filters?

[@tanaysaxena8850]

The order is actually the order specified in web.xml file .Here Navin is just putting @WebFilter annotation and with annotations we cannot specify the order of filters.

[@vikramrathore3998]

sir you have typecasted ServletRequest to HttpServletRequest and stored it in req but never used that......so what is the use of typecasting??

[@ambeshtiwari9977]

int id=Integer.parseInt(req.getParameter("aid")); then using if condition using aid

[@JujareVinayak]

8:05 in line 30 instead of request use req.

[@matiny142]

But you didn't use req object after casting☹️

[@funfamily4497]

when i am creating the same jsp and servlet as in this tutorial, i am getting following error: Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. I am able to enter the id and name. i have given the same name in action tag(in jsp) and in @WebServlet() Please help me out

[@highongameshog2439]

you should be commenting all the sevlet & servlet-mapping tags in the deployment descriptor.Thats why your server is having trouble to find the source file.

[@highongameshog2439]

if you're using annotations

[@su5871]

not able to connect servlet to filter. i am giving mapping in web.xml

[@santhoshkumarramakrishnan2474]

done it

[@sunilreddy814]

Finally 😅🙏
