response.setStatus

[Yogesh Hingmire]

Hello ranchers,

will a response.setStatus() result in activating the error handling mechanism.
i mean when we use this mehtod with status code as 4xx or 5 xx and i have the <error-page> in the web.xml for these codes ?

My guess is it wont activate the web.xml declared error page handling
mechanism.

could you please let me know on the same.

Thanks,
Yogesh

i think you are right, setStatus(int statusCode) does not interact with the error page defined in the <error-page> tag in web.xml
This method does not trigger the container to generate an error page. It just sends the status code to the browser.

Can anyone confirm ?

It's clearly written in the API for setStatus() :
If there is an error, and the caller wishes to invoke an error-page defined in the web application, the sendError method should be used instead.

7. Instead of displaying the standard HTTP 404- NOT FOUND message for all bad requests to a web application, you want to display a customized page. Which of the following is the correct way to do this? (Select one)

a You have to check the servlet container documentation and change the default error message file.
b You have to change your servlets to redirect the responses to your customized error message file.
c You have to specify the mapping of the error-code (404) and the customized error page in web.xml.
d You cannot do it in a standard way.

Answer: c

Explanation

You can map error codes to error pages just as you map exception types to error pages. The following web.xml snippet maps 404 to
V

<error-page>
<error-code>404</exception-type>
<location>customnotfoundpage.html</location>
</error-page>

but i am not sure which method will trigger the custom html page -

setStatus(SC_NOT_FOUND);
OR
sendError(SC_NOT_FOUND);

hth and also please anwer my question !

[Christophe Verré]

sendError will trigger it.
