JSPs and Servlets Tutorial 05 - The POST Method and Passing Parameters

[@potatopotato4676]

Watching these tutorials 12 years after launch, still they feel really high quality. It's like buying a quality product and it works a lot longer than economical ones. Thanks!

[@trocandobytes]

Agree!!

[@LiveLoveLaughEveryday]

Every tutorial of yours is excellent. Many of my confusions are resolved after watching your tutorials. I just hope you keep producing the tutorials. Your ability of making complex things simple is just amazing. It's a unique talent. Thanks a lot!!!

[@kart0624]

Thanks for doing this man. I know it takes time and effort, and passing this knowledge on for beginners is really great. Thanks again.

[@photonpoint7086]

At the end I'm able to understand Java Web with your generous efforts. Thank you so much. I hope so we will able to watch your JSF Tutorials.

[@arkanglegeibriel]

As someone new to this, this is my ONLY complaint. I'm still learning the difference between xml and html. His eclipse theme (default) displays the color schemes the same on both. EVEN THOUGH HE HAD CLEARLY MADE AN HTML FILE, I had the xml bias in my head. This isn't a problem with the presenter as he's done a magnificent job. But in case this confuses anyone else I thought I'd post this. Good luck to anyone here to learn!

[@DeanGl]

I, for one did. But It's so long ago that I'm currently watching these tutorials to refresh my memory. I'm not in the US though.

[@MukulTripathi]

I found this video as the most important video of the tutorial series.

[@halflifethenna]

[@brvdley6442]

Your disk was almost full back then man, hope you got more space by now

It is clear. Thanks for sharing!

[@zPathwalker]

Such an awesome tutorial!

[@chiragjain9490]

I m not getting that how an html file is called from servlet.....bcoz in the main method there is not a single line which is indiacting towards html file

[@sfathimasajini]

really very good and it is very usefull.....

[@maravindh]

You are awesome man..

[@LeCoffeeMonster]

Guys to address the problem, check that your is the same as in web.xml /xmlServletpath xmlServletpath must be the same spelling in both, i got 404 because spell it wrongly Hope this works

[@Dragosknight]

Kousik it's throwing 405 error what is the reason. It says that url not supported

[@vinaymolige7998]

excuse me sir i am getting HTTP method POST is not supported by this URL please tell me how to fix it

[@Lasetacular]

Nope, I'm watching this video at my first job. Surely you'll be more marketable to know this stuff, but I'm not sure it's expected as it is mostly an enterprise practice.

[@IvoShurbanovski]

keep on working. you are really great teacher. let me now ask you a question. in the simpleform.html when i click submit query I get an error 404. when I run the xmlservlet independently it runs without a problem. solution?

[@LordCarringtan]

Did anyone here learn this in college (undergrad)? I'm currently in college and we don't learn any Java Web Information so I am teaching it to myself to be ready for the job market. But I'm curious did you learn this in your undergrad studies?

[@poojarevankar107]

Hi , Whenever i hit Submit Query button, my url will be localhost:8080/xmlServletPath instead of localhost:8080/SimpleServletProject/xmlServletPath..i.e Project name goes missing.so i get Webpage not found page.... when i manually type project name it works fine.. FYI..I have put url pattern in form action.. Please suggest..

[@gogetadexter]

+pooja Revankar Im getting the same problem. I have used annotations for the URL pattern. Did you find any fix?

[@amitgiri1790]

I think you have used action= "/xmlServletPath" in form field. Remove that "/" . user action ="xmlServletPath". I was also getting the same problem. I fixed it by removing "/"

[@Akashpatil-pf6hm]

yup it worked thanks

[@nupurjaiswal957]

Thanks Amit. I solved the same issue using your solution

[@mikesca1980]

I found my problem , but i do not know the fix. It seems like once i ran a html files, it stays the same and do not take the changes made later on. I had to recreate a new file by making sure everything is correct before running it on server. I wonder where is files cached

[@DaBBoSaH]

fanx greattttttt

[@mikesca1980]

One addition : When i run the SimpleForm.html in eclipse and try to view source code. the method="post" disapeared? although i can see it on the editor.

[@ChandanKumar-rl6df]

hey Kousik, After clicking submit button it is not transferring to xmlServlet page and showing 404 error. I have made same code as u have done.

[@FarahNazifa]

So far so good. But this doesn't work exactly the way you showed. The problem is - after I create a form with two inputs. That works. After I click on the button, the url changes to localhost:8080/xmlServletPath?userName=Farah and HTTP Status 404 - /xmlServletPath on the screen! I am looking forward for an answer how to resolve this problem. Thank you. :)

[@abbykr999]

Be sure to set i.e. no ''/'' character, which is obviously present in "url-pattern" tag in web.xml file... and also when you edit your html file, saving and re executing it is not enough. The changes don't take place somehow, even restarting tomcat doesn't help,weird huh!. You need to refresh the eclipse browser. Hope it helps...

[@TheMazem]

HI koushik,Am very new to Java EE.I have a small issue.i,e: When the java source file is changed, tomcat is not reloading the context automatically, it is reloading only when i build the source file.can you please let me know why the reloading is not happening automatically when the resource file is changed in my case.

[@rsscssr1]

hi, why don't you close writer of response object? is there special sense or it's just because of tutorial?

[@mikesca1980]

I can't get the servlet doPost work. I have method="post" on the html form and i have implemented the doPost method on the servlet. It doesn't call the doPost method. Anyidea? I saw you had the same problem before the refresh but i have refresh my buildin browser

[@2011jiqbal]

IF UR HTML PAGE is not loading well.. hit the refresh button inside the eclipse internet browser

[@ivarjar]

I dont get it he is using only using Out.println() function, but no HTML tags are present, then how does the browser render the ouput. If i remember correctly he said outputs should be inside HTML tags. corrrect me if i am wrong.

[@llitfkitfk]

I use SimpleForm.html not working when I use doGet() method But after I change the name SimpleForm.html to others like form.html or simple.html...., it is working! Why?

[@saivatsav8377]

Hi Sir after submitting the simpleform.html i am getting an error which is "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists". Can you please help me with that..Thanks in advance.

[@sasmalpayal]

I would like to know that what is the uses of the setContenttype method.

[@kacperopyrcha6056]

I was also confused about that. I find answer on stackoverlfow: stackoverflow.com/questions/14291027/what-is-the-use-of-response-setcontenttypetext-html-in-servlet hope this explain you everything :)

[@shaik119]

I am still getting 404 http status not found. No problem with server. Localhost 8080 loads apache home page.

[@muhammedrefaat8661]

i'm just learn a little object oriented concepts in C# (from beginneng to inheritance) ... and i didn't learn any java that's made me hate my college coz they don't focus on one major but some network some DB some embedded systems some computer vision ... i hate it

[@FACE90966]

I have a problem. If i click on the project then choose run on server, i get Null in jsp getAttribute. But when i click on the servlet then run on server i dont get Null attribute. My question is why? I hope you understand my problem.

[@thevagabond85yt]

post it on stackoverflow.com/

[@maddy0891]

+Bibhu Prasad yes i jus removed the space while typing ?username=yourname

[@keshubmathur6972]

I am getting a file download - security warning . Can anyone tell me why?

[@DarkMassFabrikator]

ty ty ty

[@apbassboost]

private void ? () throws what?

[@moezrebai7462]

thanks

[@pranavsrikartata3350]

this is working for me if I give URL pattern as /xmlservlet but not working if I give it as /xmlservletpath...i couldn't understand why...could anyone please explain this to me

[@ivarjar]

In the previous tutorials i think he has mapped the url pattern to /xmlservletpath instead of /xmlservlet(default). He has done it in the web.xml file. The default mapping is the servlet class name which is in your case.

[@akshivepandey4163]

i've done exact same thing but, getParameter is returning null value why ? can anybody help ?

[@reloaderify]

Check if the "userName" field in html is the same as in 'request.getParameter("userName")'

[@rhythmnarang6455]

its mapping on the url localhost:8081/SimpleServletProject/SimpleServletPath?userName=m .......instead of SimpleServletPath it should be xmlServletPath. coz i have given my form action as

[@madhurapradhan4439]

I get null value in doGet Method instead of the username i am typing in url....i did every step as told by you...still

[@bibhuprasad4050]

Madhura Pradhan Did you get the output?. Even I am facing the same problem

[@madhurapradhan4439]

Bibhu Prasad yes i just removed space while typing ?username=yourname in url

[@bibhuprasad4050]

Madhura Pradhan I got the output also. I didn't refresh the browser.

[@gilbertslam]

+Madhura Pradhan in the HTML form tag, do you have the input name set as username?

[@TomasProchazkaCZE]

Dude you are getting more and more silent in every video :-D Just keep continue with these tuts and i will send you some money for some new mic :-D
