Thanks for the tip; it helped me to look for the right thing and verify that 
HTML 4.01 specification indeed states exactly what you said: 
http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4

I believe line breaks in HTTP are always represented as  pairs,
regardless of the Client or Server OS's

The OS with the browser submitting the page is Windows?

Hi,

I have been stumped by the following problem: newlines within text received 
from an html form show up in the form ”\r\n” in our Struts 2 -based 
application. I am wondering how this is possible because I have verified the 
following:

1) The system is running on OS X or Linux, so the OS default newline is ”\n”.

2) The Java virtual machine reports ”\n” as its newline character 
(System.getProperty(”line.separator”)) when running the Struts 2 -application 
in a debugger.

3) When inspecting the form text in a browser debugger, the text shows newlines 
in the form ”\n” just before the form is submitted. I double-checked this by 
inspecting the actual character code values.

4) When I set a breakpoint to the bean-setter of the corresponding action in 
the Struts 2 application and let the form submission from the browser be 
executed, the setter receives the form text as a String-parameter where the 
newlines have become ”\r\n”.

What can be the reason for this? The form submission mechanism (something on 
the browser-side or in Tomcat) or the way Struts 2 handles form parameters 
before feeding them to the action? I want to get rid of these extra carriage 
returns but would very much like to find some other way than writing special 
code (such as a custom parameter interceptor) for reverting the text back to 
its original form...

Mysterious(?) carriage returns

[Heikki Hyyrö]

Hi,

I have been stumped by the following problem: newlines within text received 
from an html form show up in the form ”\r\n” in our Struts 2 -based 
application. I am wondering how this is possible because I have verified the 
following:

1) The system is running on OS X or Linux, so the OS default newline is ”\n”.

2) The Java virtual machine reports ”\n” as its newline character 
(System.getProperty(”line.separator”)) when running the Struts 2 -application 
in a debugger.

3) When inspecting the form text in a browser debugger, the text shows newlines 
in the form ”\n” just before the form is submitted. I double-checked this by 
inspecting the actual character code values.

4) When I set a breakpoint to the bean-setter of the corresponding action in 
the Struts 2 application and let the form submission from the browser be 
executed, the setter receives the form text as a String-parameter where the 
newlines have become ”\r\n”.

What can be the reason for this? The form submission mechanism (something on 
the browser-side or in Tomcat) or the way Struts 2 handles form parameters 
before feeding them to the action? I want to get rid of these extra carriage 
returns but would very much like to find some other way than writing special 
code (such as a custom parameter interceptor) for reverting the text back to 
its original form...
