Why do you write that your Struts Action is the place that your code is printing the raw file yet your stack trace shows you are in a JSP? Is your JSP invoking an action? If so that's your problem: everything is probably already committed, Stream-wise that is. How are you getting to this action code you included from a JSP? Shouldn't JSP's and taglibs only use the Writer? Mixing that by calling some sort of action to get OutputStream doesn't sound like a good idea, at least not according to the Tomcat Servlet docs on interface ServletResponse method getOutputStream() and getWriter(): Either this method or getWriter() may be called to write the body, not both.
