SCWD-STUDY GROUP

[Karthik Prabhakar]

Hi Guys,

I was just wondering if someone is starting on SCWD , if so shall we start on study group and work on chapters and discuss over chat and get each ones ideas across and effectively clear the certification with good marks.

Chatting and studying as a group really helps.

I wouldn't mind meeting in an Instant Messaging Chatroom (since many of us are thousands of kilometers away from each other) where we can discuss topics.

[Dinesh Sundrani]

Great Idea, M Interested. I have just got the HFSJ book.

Dilshan seems like a better option iam fine with it

[Karthik Prabhakar]

We will work on the schedule as from monday
chapter 1 -2 days 12th and 13th for study
14th is the day for discussion ofcourse its not strictly 14th alone we can talk abt it as it goes...

but from 15th next target for chapter 2 will start k.

tell me the feasibility from all the guys who r to start with it or any suggestions on start date or more days for chapter 1 is welcomed pour all ur suggestions

[Dilshan Edirisuriya]

That's okay but I don't think chapter 1 & 2 are too dificult. No need to waste 2 days for dat. From chapter 3 we can have 2 days to study
I don't know whether you are agree.

Hi guys!
I�ve been studying for this certification but since I work I find it difficult just have one or two days for each topic. Can�t we just talk about topics regardless of the chapter?

[arul ganesh]

What are idempotent methods of these and why ??

PUT,DELETE,TRACE,POST,GET,HEAD

[Ramedeus Ramirez]

Hello Ranchers,

This is of interest to me too. How can i get in touch with you all? where are you guys at(regards to HFSJ) right now. Sombody let me know

[vinuharan haran]

PUT,HEAD,TRACE,GET,DELETE,OPTIONS are all idempotent.Meaning they yield the same results for any number of identical requests.

Thanks,
vinu.

[Dosapati Kalyani]

Hi Vinu,

Can u give me one practical example which simulates about "GET is idempotent & POST is not idempotent" ??

Thanks
Kalyani

[Muthuvel Ramamoorthy]

Hi Guys, i start today reading Head First Servlets & JSP and i have a voucher which expired 31 July 2006. I think i have short time but hope to pass. I would like to join in this conversation also.

I have completed my 1.4 today an hour before.

Thank you

[Karthik Prabhakar]

Vinu/Kalyani,

GET,HEAD,OPTIONS,TRACE - NONIDENPOTENT
PUT,DELETE,POST - IDEMPOTENT

WHEN U MEAN BY THE TERM IDEMPOTENT U MEAN TO SAY WHEN WE USE THESE METHODS IT SHOULD NOT CHANGE ANYTHING THATS RESULTS FROM THIS CALL,

DELETE CAN DELETE THE FILE ON SERVER IF THAT METHOD IS USED,PUT CAN LOAD A FILE TO THE SERVER IF ALREADY A FILE WITH THAT NAME EXISTS IT WILL OVERRIDE IN THE SENSE IT TRYING TO CHANGE SOMETHIGN ON THE SERVER SIDE ,OFOUCRSE POST CAN DO ALL THE TWO IT CAN DELETE AND UPLOAD LIKE PUT SO THESE THREE METHODS R CALLED IDEMPOTENT WHICH MEANS CHANGES THE STATE OF ANYTHIGN IN THE SERVER ,

REST ARE CALLED NONIDEMPOTENT WHICH WHEN USED WILL NOT CAUSE ANYTHIGN CHANGE ON ANYTHIGN ON THE SERVER.

[Ulf Dittmer]

Karthik,

please don't shout at us in all uppercase letters. It's unnecessarily hard to read, too.

[Karthik Prabhakar]

Sorry abt that Ulf

[Ulf Dittmer]

GET,HEAD,OPTIONS,TRACE - NONIDENPOTENT
PUT,DELETE,POST - IDEMPOTENT

You switched the descriptions. GET is idempotent, while POST is not.

[vinuharan haran]

Hi Dittmer,
According this link...
http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9
GET,HEAD,PUT,DELETE,OPTIONS,TRACE are all idempotent.
Kindly explain on this...
Thanks,
vinu.

[Praful Thakare]

Hi Vinuharan,

in above mention site definition of idempotent is ,

A method is idempotent if side-effects of "ALL identical" requests is the same as for a single request.

Now if we talk about PUT it has to be idempotent as all the identical request will always put same file on server so the side-effect is same, now ideally even DELETE will try to delete the same file that will have same side effect, but practically its not possible to delete same file.

Some one kindly let us know what is expected answer in exam
are DELETE and PUT idempotent ?

Cheers
