getOutputStream() has already been called for this response
Hi,
I am getting the *java.lang.IllegalStateException: getOutputStream()* has
already been called for this response when I use *return
map.findForward("success")* at the end of action method. But this exception
wont appear if I return null. As I am not using writer object. But this will
not display an error message in the jsp through action messages.
I am using struts1.3.
How to avoid the above said exception so that I can generate a pdf when
success and print a message when failed. As this is occurring because both
writer and outputstream are using at the same time.
Is it possible to close the outputstream after generating the pdf and after
that to send the message struts jsp using default writer.
My code is:
public ActionForward execute(ActionMapping map, ActionForm form,
HttpServletRequest req, HttpServletResponse res) throws Exception {
String savefilename = req.getParameter("savefilename")+".pdf";
FileForm file2 = (FileForm) form;
ArrayList list = file2.getList();
FormFile f2 = (FormFile) list.get(0);
Boolean b1 = validate(f2.getFileName());
if(b1==false){
ActionMessages messages = new ActionMessages();
messages.add("sts", new
ActionMessage("common.generatepdf.onlyimages"));
saveErrors(req, messages);
return map.findForward("success");
}
ServletOutputStream outStream=null;
Document document=new Document(PageSize.A4,0,0,10,10);
res.setContentType("application/pdf");
res.setHeader("Content-Disposition","attachment; filename="+savefilename);
outStream = res.getOutputStream();
PdfWriter writer = PdfWriter.getInstance(document,res.getOutputStream());
writer.setStrictImageSequence(true);
document.addHeader("String","Content");
document.open();
try{
for (int count = 0; count < list.size(); count++) {
FormFile f1 = (FormFile) list.get(count);
Boolean b = validate(f1.getFileName());
if(b==true){
Image convertJpg = Image.getInstance(f1.getFileData());
if(convertJpg.getDpiX()>75 & convertJpg.getDpiY()>75){
convertJpg.scaleToFit(200, 200);
}
document.add(new Paragraph());
document.add(convertJpg);
}
}
document.close();
writer.close();
ActionMessages messages = new ActionMessages();
messages.add("sts", new ActionMessage("common.generatepdf.success"));
saveMessages(req, messages);
}catch(Exception e){
ActionMessages messages = new ActionMessages();
messages.add("sts", new ActionMessage("common.generatepdf.fail"));
saveErrors(req, messages);
}
finally {
if(outStream != null)
try {
document.close();
writer.close();
outStream.close();
outStream.flush();
catch (IOException e) {
e.printStackTrace();
}
}

Re: getOutputStream() has already been called for this response
Posted by Dave Newton <da...@gmail.com>.
A request can only return one response: the file, or a forward (assuming
it's not some sort of streaming forward).
That method is pretty hard to follow, and should be refactored, IMO.
