Change encoding of HttpServletResponse

Question

Hi,

I have an API that returns XML, it actually returns it using the default encoding (I believe it's UTF-8), but now requirements have changed and we need to return everything in UTF-16LE.

My question is: is there an easy way of doing this? I have access to the response just before the calls complete so I was wondering if I could do something like

//This method does not exist
response.setCharacterEncoding("UTF-16LE");

Thanks a lot!

UPDATE: The method mentioned is the one to use. I was using an old version (2.3) of the servlet API that did not include it. Changing the version fixed it all.

Answer 1

First

response.setHeader("Content-Type", "text/xml; charset=UTF-16LE");

Then, make sure you're actually emitting that encoding!

Answer 2

Uhh, the method does exist, here

Sets the character encoding (MIME charset) of the response being sent to the client, for example, to UTF-8. If the character encoding has already been set by setContentType(java.lang.String) or setLocale(java.util.Locale), this method overrides it. Calling setContentType(java.lang.String) with the String of text/html and calling this method with the String of UTF-8 is equivalent with calling setContentType with the String of text/html; charset=UTF-8.
