I just came here to say thank you so much for sharing and explaining the knowledge that you have, you explain with so much patient and passion that I was able to understand completely. Keep up the good work.
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!!!
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
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
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.
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.
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.???
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
@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
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
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
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
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
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
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.
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.
Any UI experts here...? Sir i have a doubt.. I have two UI project, i have done gulp build for both the project.

String aname = (request.getParameter("aname"));
PrintWriter out = response.getWriter();
System.out.println("milan");
if(aname.length()>3)
chain.doFilter(request, response);

Great tutorial Reddy sir. Completed the assignment.

Thankyou sir, it's really helpful to me, salute sir
Thank you sir, I have completed the Assignment given by you.
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");
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
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
Thank you so much sir for great explanation of concepts
Done with assignment sir. Thank you very much
I did it sir... thankyou sir for sharing your knowladge for us...
Best teaching :)
Is it Really Important to Typecast ServletRequest to HttpServletRequest?
This entire 35-videos playlist for JSP has been very useful. Thank you.
BTW, why do you address everyone as "aliens"?:D
i was going to ask the same question xd
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.

New Filter Implementation done!
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
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.
if you're using annotations
how to make the filter to the specific servlet
.. sir how to differentiate Get , Post request in filter
if(aname.length()>=3)
chain.doFilter(request,response);
else
out.println("Invalid text input")
we can use regular expressions instead
Mr. Telusko:
I think It should be:
int aid=Integer.parseInt(req.getParameter("aid"));
I have the same thought. It should use the req not the request.
Nice explanation but please slow down the speed of speech delivery.
It's really nice sir. But how to configure this filter in web.xml file?
Nice explanation
Done homework easily
sir you have typecasted ServletRequest to HttpServletRequest and stored it in req but never used that......so what is the use of typecasting??
int id=Integer.parseInt(req.getParameter("aid"));
then using if condition using aid
8:05 in line 30 instead of request use req.
how to apply one filter on multiple servlets??
THANK YOU SIR I AM A STUDENT OF I
NEURON
hey how can we maintain order of filters?
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.
Sir how to display all images from folder to jsp page sir please make on it.

sir i understood but please explain little bit clearly noting but with lot more 2 to 3 examples.
Done Name Filter!!
thank u much n u r the best
