Hi
I'm using a DownloadAction to generate a PDF and return it the the
browser. If there is a problem generating the PDF however, I want to
redirect the user to a specific JSP.
What's the best way of doing this? At the moment I am using
protected StreamInfo getStreamInfo(ActionMapping mapping, ActionForm
form,
HttpServletRequest request,
HttpServletResponse response) {
...
...
...
if(problem)
servlet.getServletContext().getRequestDispatcher("/admin.do?doAction=alr
eadyPrinted").forward(request, response);
return null;
}
else {
return new ByteArrayStreamInfo(contentType, myPdfBytes);
}
}
This works, but I always get a NullPointer, because I'm returning null
to satisfy the method signature. The exception doesn't cause a problem
for the user though, because the forward has already happened by then
(and the user is happily viewing the JSP)
Is there a better way to do this though - perhaps with
ResourceStreamInfo instead?
