Lucas you posted this question by replying to the thread: Re: Does struts really have to construct a new form bean every time?
Please do not hijack a thread when replying to an e-mail on a mailing list (this includes also simply changing the subject and replying). Your question has nothing to do with the original thread. When you have a new question please post a brand new message.
In relation to your question, I'm not exactly sure where the problem is. I'm guessing you are probably displaying html from the JSP and then calling your tag, which by that point I'm pretty sure you can't change the content type of the page. I'm not sure how jfreechart works but can't it just return an image and you could simply use it as an image on the page vs trying to change the content type of the page (assuming that what's your trying to do?)
