i'm using tomcat 8.5 and i got an hhtp error 405 when i submit my two int it says " post method is not supported by this url" but i'm using get method. please help me.
Type : Status Report Message : The requested resource [/FoodMart/AddServlet] is not available Description : The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. Sir, can you please tell me what's getting wrong here; In html file after submitting 2 numbers; rather than showing output in console its showing above error.
Great explanation, but please slow down just a little bit. At first I though I got you on 1.25 speed 🤣🤣 But on the other hand... I don't need to put you on speed 😅 Anyway... Thank you!
When you are calling the SqServlet, and when it's printing, "result is 64", the URL of that page remains as localhost:8080/DemoApp/add?num1=6&num2=2. Shouldn't it be DemoApp/sq since it's from that Servlet?
I think since we are using request dispatcher In the AddServlet we could have directly said request.getAttribute("num1") in sqServlet since requestdispacther doesn't create a new request object it uses the same request object
I use post method in the first servlet and i notice the the url is add. So let's say that, servlet 1 call servlet 2, the servlet 2 send back the resp to servlet 1 and servlet 1 send the result on the browser???
Piyush Agarwal Hi Piyush, Java and JavaScript both are different web technology. Java is used for Server Side technology, which processed on big servers to handle millions of users across worldwide. JavaScript is client side technology, which runs in your machine browser. Both technologies serves basic purpose of web. JSP is one of Java EE technology to develop enterprise application. Whereas with advancement of JavaScript, specially introduction of Node, Java Script can also be used to develop server side code using serverless technology. It is another fact that JavaScript has name ECMA Script, due to encash popularity of Java, it is named JavaScript. Hope this reply sufficient for your question.
When we fetch an object of RequestDispatcher interface , using the method getRequestDispatcher(string), how does it work internally? Like RequestDispatcher is an interface(which cannot be instantiated ) , so how does this method create its object?
ok but how to just intercept res object from SqServlet if you just dedicated this servlet to computation and just return the square number in the AddServlet ?
when i m passing the value using post method isnt not working while its working with get method why is so for this example above since both the method passes the value
sir what if 1) i tried to print sum(k) on AddServlet and square(of k) on SqServlet 2)why we have to decleare req,and res on SqServlet page in doGet() methord
Hello sir..I am facing problem in executing this code servlet into another servlet that is i am not getting result as ""Hello to sq"" but getting previous result of addition??please help...
Pavan Rai Let him finish these servlets one .. He is uploading Java core, servlets at same time. I am also waiting for spring but let us first learn this one.
SIR,REQUESTDISPATCHER IS NOT WORKING IN MY ECLIPSE OR SERVER , WHENEVER I RUN IT ON THE SERVER (TOMCAT 8.5) IT SHOW A HUGE ERROR AND TELLING STACK IS OVERFLOW, PLEASE HELP
Check your spellings too. often time i write deGet instead of doGet. Or the Class names... and make sure you are writing the same the class name in your web.xml...
In href="cart?uid=u.getId()/bid=b.getBId()" can we change this to href="cart" and can we use session to handle the userid and bookid Can you post a video of how to use session for a list of books or anyother items

Bedankt

Spectacular sir. The confidence is increasing day by day by seeing your tutorials. No words....huge respect from AP.
I enjoyed it a lot after watching the theory of that rather than watching before theory
The greatest video that I ever seen before comparing with others
very conceptual teaching,thanks a lot sir.....its really good that you are moving forward with basics

Great Servlet tutorials so far, keep going, it's really helpful. Greetings!
Yes navin, we are enjoying the video
Great explanation, but please slow down just a little bit. At first I though I got you on 1.25 speed 🤣🤣 But on the other hand... I don't need to put you on speed 😅 Anyway... Thank you!

req.setAttribute() and req.getAttribute() methods belong to which type of session manangement
Easy to understand. Good work. Very helpful !!!
service() and doGet() doPost() method are public or Protected????
I use post method in the first servlet and i notice the the url is add. So let's say that, servlet 1 call servlet 2, the servlet 2 send back the resp to servlet 1 and servlet 1 send the result on the browser???
Http status 500 - Internal sever error is being generated
Pls respond
I'm really enjoying your videos! 😁

@Telusko Learnings How to call multiple servlets from a single servlet? Which servlet is responsible for creating res object then?
When we fetch an object of RequestDispatcher interface , using the method getRequestDispatcher(string), how does it work internally?
Like RequestDispatcher is an interface(which cannot be instantiated ) , so how does this method create its object?
ok but how to just intercept res object from SqServlet if you just dedicated this servlet to computation and just return the square number in the AddServlet ?
when i m passing the value using post method isnt not working while its working with get method why is so for this example above since both the method passes the value

how to resolve this??
sir what if
1) i tried to print sum(k) on AddServlet and square(of k) on SqServlet
2)why we have to decleare req,and res on SqServlet page in doGet() methord
It's shows error when I use doPost() and method=post in html file why don't we use use these?
At my end, I have to specify the argument for function getRequestDispatcher as "/sq" instead of "sq". Not sure why.
its working like a directory that is the main reason
Casting an object to int value doesn't work. Somebody knows why?
@Артем Воробкин thank you!
