http://nagoya.apache.org/bugzilla/show_bug.cgi?id=26409 Document what to do if an Action doesn't need to be forwarded anywhere in the end? Summary: Document what to do if an Action doesn't need to be forwarded anywhere in the end? Product: Struts Version: 1.1 Final Platform: Other URL: http://jakarta.apache.org/struts/userGuide/building_cont roller.html#config OS/Version: Other Status: NEW Severity: Enhancement Priority: Other Component: Documentation AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Some actions like the ones displaying an image coming out of a database or downloading a file do not need to end with a next action or page (I guess the browser works on them in a thread separate from the main web-page body processing). The above documentation reference (see URL field) and http://jakarta.apache.org/struts/api/org/apache/struts/action/ActionMapping.html don't seem to have a recommendation for this. This is however a problem because Action.execute() always needs to return an ActionForward object. As per Bug 26408, this causes an IllegalStateException in your log which is kind of a false alarm if seriously work on your logs. Sample core part of the execute() method for illustration: response.setContentType(img.getContentType()); OutputStream out = response.getOutputStream(); InputStream is = img.getImgStream(); int c; int i = 0; while ((c = is.read()) != -1) { out.write(c); i++; } return actionMapping.findForward(????); --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
