The appropriate return value for actions that generate their own output
is null. This is rarely the best solution, though, as there's more to
the http protocol than the content of the response. You're returning no
header information.
curl http://localhost:8080/congo/public/getConfiguredStylesheet.action
try curl -i to see the header info. Compare that output to a curl -i
request for a .css file delivered by your web app through more
conventional methods.

I believe that since you're generating the response yourself this has no
effect.

I was assuming he just meant that he wanted to feed the output out from a stream, although you're right -- unless the content is really large that does seem like extraneous overhead. Probably that means he's got a bunch of data in a database that he just wants to dump...but there's no real reason that can't be done as a jsp (the tags would allow all the looping, conditionals, etc. he's probably looking for), and if there's just a block of content to be included directly from the DB, that can be output there, too... -Dale - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

Re: Bizarre sporadic problem with streaming a stylesheet. [Solved?]
So this got weird. I tried everything. Rewrote the method, changed the responses, put debugging all over - nada. I could reproduce the problem by rapid-firing ^R at the browser, and the home would render with the stylesheet about half the time. It was interesting seeing it flip back and forth. My JSP's had two stylesheet lines in them, like this: LINK REL=StyleSheet href=getStylesheet.action type=text/css LINK REL=StyleSheet href=getConfiguredStylesheet.action type=text/css The first one would have loaded the 'default' style, with the configured oversion overriding / updating the sheet as necessary. I removed the first one. And it all started working perfectly. I don't know if it's a bug in the first action class (which HAD been working perfectly on it's own until I added the second line), or what - but I'm running now. How. Weird. -d - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

Is your request going directly to the app server on which this is running, or is some apache httpd/proxy/etc. in between that might be adding in extra info? If not I wonder where those are being added, or what's actually happening between so that when you say write(sb.toString()) other info is getting written first? Completely different theory: In how many different browsers/machines are you seeing this behavior? Is it possible that an empty answer (perhaps generated when a server was not coming up/going down/not running/etc.) has been cached by said browser and is sometimes using that instead?
