I have a JBoss Seam project already in place, and I'm trying to add a service that will return a PDF from a URL request. It's my understanding that to do that I will need to modify the HTTP response, and to do that I need a component that extends HTTPServlet. I've tried to do that but I suspect that I'm missing some vital information. The code and error are below. If you read on, thank you, and prepare to be shocked by ignorance and apparently willful stupidity. But that's why I posted it in the Beginner's Corner. The component code looks like this: @Name("printServer") | @Stateless | @Scope(ScopeType.PAGE) | public class PrintServer extends HttpServlet implements IPrintServer { | | private static final long serialVersionUID = 1278807414184735439L; | | @Logger | private static Log log; | | public String test(String message) { | log.info("Running printing test method", "Arg = " + message); | | return "Printing test message = " + message; | } | } The interface code (do I even need to do that?) looks like this: @Remote | public interface IPrintServer { | public String test(String message); | } The servlet mapping in web.xml looks like this: <servlet> | <servlet-name>Print Servlet</servlet-name> | <servlet-class>com.mckesson.hbi.services.PrintServer</servlet-class> | <load-on-startup>2</load-on-startup> | </servlet> | <servlet-mapping> | <servlet-name>Print Servlet</servlet-name> | <url-pattern>/services/pdf/*</url-pattern> | </servlet-mapping> | The page I'm using it in looks like this: <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" | "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> | <ui:composition
