Re: Unable to change content-type with Interceptor?
Hello all,
I was just looking for this option to override the content-type of the
json result. Is there any fix for this?
Thanks

Lukasz -
Thanks for all your help. You got me on the right track and it appears
the
json Result was what was overriding and setting the content type. As a
result, I have overridden the JSONResult class to use the dynamic
content-Type.
You're welcome :-)
/**
* Custom json result type to set Content-Type response header
dynamically
to either 'application/json' or 'plain/text'
* according to what the request header identifies in the Accept header
*
* (this is to fix browser wanting to download the json response on an
ajax
submit)
*
* @author Burton Rhodes

*/
public class JsonDynamicContentTypeResult extends JSONResult {
private static final Logger LOG =
LoggerFactory.getLogger(JsonDynamicContentTypeResult.class);
@Override
public void execute(ActionInvocation invocation) throws Exception {
ActionContext actionContext = invocation.getInvocationContext();
HttpServletRequest request = (HttpServletRequest)
actionContext.get(StrutsStatics.HTTP_REQUEST);
HttpServletResponse response = (HttpServletResponse)
actionContext.get(StrutsStatics.HTTP_RESPONSE);
// Set Content-Type according to what the request will accept
if (request.getHeader(Accept)!=null
request.getHeader(Accept).toLowerCase().contains(application/json)) {
this.setContentType(application/json);
} else {
// Default to text/plain
this.setContentType(text/plain);
}
try {
Object rootObject;
rootObject = readRootObject(invocation);
writeToResponse(response, createJSONString(request,
rootObject), enableGzip(request));
} catch (IOException exception) {
LOG.error(exception.getMessage(), exception);
throw exception;
}
}
}
Right now contentType isn't dynamically resolved, please register an
issue and I'll add such option to JSONResult so you will be able to
specify contentType via param/ tag, eg.
result type=json
param name=contentType${resolveContentType}/param
/result
and the action's resolvedContentType method will be called to obtain
valid contentType
Happy New Year :-)

Re: Unable to change content-type with Interceptor?
2012/12/30 Burton Rhodes burtonrho...@gmail.com: I'm not sure what I'm doing wrong, but I cannot for the life of me change the content-type of the response using an interceptor. My interceptor code is below. The example below seems a bit absurd, but eventually I will add code to change the content-type dynamically from application/json to text/plain depending on what the request will accept (this is to fix an IE bug related to ajax file uploads). What am I missing here?

Re: Unable to change content-type with Interceptor?
Just tried that without success. Oddly, even when I debug the code, the reponse.contentType is not changed immediately after the line: response.setContentType(text/plain). I am wondering if the contentType cannot be set twice (or overridden once set)?
